Milk fever, also known as parturient paresis or hypocalcemia, is a metabolic disorder of dairy animals that occurs around calving due to low blood calcium levels. Multiparous, high producing cows and buffaloes fed lush green fodders like alfalfa before calving are most susceptible. Clinical signs include anorexia, muscle shivering, depression, staggering, and recumbency. Treatment involves intravenous calcium injections, while prevention focuses on feeding a low calcium diet before calving and prophylactic calcium supplementation around calving.
Metabolic disorders in dairy animals are disturbances in metabolic processes that often occur around calving. Key periods are the last 3 weeks of pregnancy and the first 3 weeks of lactation due to hormonal and dietary changes. Common metabolic disorders include milk fever, ketosis, fatty liver disease, left displaced abomasum, and laminitis. Preventing these disorders requires careful management of nutrition, especially transition diets between dry and lactating periods.
Black-leg is an acute, infectious, and highly fatal bacterial disease that affects cattle, buffalo, sheep, and goats. It is caused by Clostridium chauvoei bacteria which form spores that can survive in soil for years. The disease is typically contracted by ingesting contaminated feed or soil. Symptoms include high fever, lameness, and swelling of the hip, back, or shoulder muscles. The infection causes necrosis of muscles which leads to gangrene and death within 12-48 hours in most cases. Treatment involves antibiotics, draining swelling, antitoxins if available, and fluid therapy but the fatality rate is nearly 100%. Vaccination is recommended before rainy season to build immunity
Impacts of heat stress on poultry productionOssama Motawae
Heat stress negatively impacts poultry production in several ways. It causes behavioral changes where birds spend less time feeding and more time resting. Physiologically, it disrupts reproductive hormones and growth rates. It also suppresses the immune system by reducing organ weights and antibody responses. In terms of production, heat stress decreases feed intake, body weight, egg production, and meat quality. It results in estimated annual economic losses of $1.69-2.36 billion to the US poultry industry.

This document discusses three common calf diseases in Jamaica: calf scours, calf pneumonia, and tick fever. Calf scours is diarrhea with many potential causes including bacteria, viruses, and protozoa. Affected calves show dehydration, fever, and bloody diarrhea. Treatment involves fluid therapy and antibiotics. Calf pneumonia is a respiratory disease caused by bacteria and viruses. Calves display nasal discharge, cough, and reduced appetite. Preventive measures include vaccination and improving ventilation. Tick fever causes fever and weakness transmitted by tick bites. Affected cattle are treated and vaccination helps prevent the disease.
Heat treatment and chemical treatments can increase the bypass protein content of feed ingredients fed to ruminants. Heat treatment through processes like autoclaving can increase the rumen undegraded protein fraction by denaturing proteins and forming protein-carbohydrate complexes. Chemical treatments using formaldehyde or lignosulfonate can also increase rumen undegraded protein by forming cross-links between amino acids or precipitating protein respectively, making it less susceptible to microbial breakdown in the rumen. The level of treatment and feed ingredient impacts the effectiveness at increasing bypass protein for ruminant digestion and nutrition.

This document discusses several sociological theories:
- Marx's conflict theory focuses on class struggle between the bourgeoisie and proletariat, with the ruling class justifying exploitation through false consciousness. Revolution would arise from class consciousness.
- Weber believed religion allowed capitalism to emerge, with Protestants valuing hard work. Conflict theory views conflict as natural due to competition over scarce resources. Schools legitimize inequalities.
- Social reconstructionism aims to create a better society through education emphasizing social reform. Freire saw education as a means for oppressed groups to resist oppression through critical thinking.
Redwater is caused by the blue tick. Signs include fever, lack of appetite, red urine, and pale eyes and gums. If not treated, it can lead to death. Treatment involves keeping cattle calm and injecting them with Berenil or Imizol. Prevention involves vaccination and testing cattle annually.
Healthy livestock are more profitable as they grow faster and produce more. Sick animals display outward signs like being listless, going off feed, being restless, or having a dull coat. Animals get sick from malnutrition, parasites, diseases, and poisonous plants. Parasites include worms, ticks, lice, and mites. Worms live in intestines and damage absorption of nutrients. Vaccinations help animals develop antibodies to fight common diseases and are given according to species-specific plans. Diseases like foot and mouth disease and avian flu can devastate herds so biosecurity, quarantines, and culling infected animals are important prevention strategies.

Skin Infection In Dogs – An Important Yet Neglected ConditionMonkoo Dog
Most Common Bacterial Infections in Dogs
Dogs have been known for centuries for their innumerable abilities and contributions. Studies have shown that bringing home a dog can change one’s life for the better. There is no better natural antidepressant remedy than a dog.
Yes, it is true that dogs are a great addition in anyone’s life but there are rules and guidelines that should be implemented especially for the well being of the dog. From healthcare to food, dogs have a different need than us humans.
This document discusses various causes of poor absorption of nutrients in young goats (kids), including coccidiosis and black scour worms. Coccidia and worms damage the lining of the small intestine, reducing the ability to absorb vitamins and nutrients. Kids with these infections have lower blood vitamin B12 levels, a less efficient immune system, and risk anemia. Without quick diagnosis and treatment, and careful nursing, the intestinal damage can be permanent, impairing absorption long-term. A fecal sample test is needed to identify worm eggs or coccidial oocysts and guide appropriate treatment.
Nematodes are invertebrate roundworms that inhabit marine, freshwater, and terrestrial environments. They comprise the phylum Nematoda (or Nemata) which includes parasites of plants and of animals, including humans, as well as species that feed on bacteria, fungi, algae, and on other nematodes. Four out of every five multicellular animals on the planet are nematodes (Platt, 1994). Cobb (1914) calculated that if the nematodes resident in a single acre of soil near San Antonio, Texas, USA, were to proceed in head-to-tail procession to Washington D.C., some 2000 miles away, the first nematode would reach Washington before the rear of the procession left San Antonio!
Ghost Worms in the Sky
Lyrics: Kathy Merrifield

The majority of nematodes are microscopic, averaging less than a millimeter in length, but some of the animal parasites are quite large and readily visible to the naked eye. The animal and plant parasites are of direct importance in agriculture, the environment, and in human health; however, most nematodes in the environment are not parasites. Nematodes that feed on other organisms are important participants in the cycling of minerals and nutrients in the ecosystem that is fundamental to other biological activity. Some of these nematodes may have major roles in decomposition, including biodegradation of toxic compounds. In fact, the incidence of certain nematode species is sometimes used as an indicator of environmental quality. Insect-parasitic nematodes can be of importance in regulating insect populations, and are being used in the biological control of insect pests.
The developmental biology of one nematode species, Caenorhabditis elegans, is better characterized than that of any other multicellular organism. C. elegans is studied as a model system in molecular and developmental biology, and is providing insights into many other areas of biology and medicine.
Livestock diseases cause billions in losses annually in the US. Three main causes of disease spread are poor sanitation, improper management, and introducing new animals. Diseases can be caused by nutritional defects, physiological defects, morphological defects, or pathogenic organisms like viruses, bacteria, fungi and protozoa. Good management practices like isolation of new animals, vaccination programs, clean facilities, adequate rations, limiting visitors, quick diagnosis, and proper handling can help prevent disease spread. Common diseases are described along with their causes, symptoms, and prevention/treatment methods.
The document discusses various animal diseases including their causes, symptoms, prevention and treatment. It provides details on nutritional, physiological, morphological and pathogenic defects that can cause disease. Common viral, bacterial, fungal and protozoan diseases are described along with their characteristics. Key points for prevention include proper sanitation, nutrition, housing and vaccination. Overall, the document emphasizes that following good management practices is essential to controlling the spread of diseases and reducing economic losses for livestock producers.
The document discusses several diseases that lowland sheep are more susceptible to compared to hill sheep, including maggots, internal parasites, and footrot. Maggots and footrot are better controlled in hill sheep due to their natural habitat, while lowland sheep are more affected by these conditions due to climate and higher stocking rates on farms. The document also provides details on maggot prevention methods, common parasites such as worms and liver fluke, symptoms and management of footrot, and an overview of bluetongue virus which can cause inflammation and hemorrhaging in sheep.

Fasciola hepatica, or the liver fluke, is a parasitic flatworm that infects livestock like cattle and sheep and causes significant economic losses. It has a complex lifecycle involving an intermediate snail host and affects animals by causing anemia, weight loss, and liver damage. Diagnosis involves examining feces for eggs of the parasite. Treatment of infected animals includes dewormers like albendazole or triclabendazole. Preventing exposure by controlling snail populations and removing animals from flooded pastures can also limit the spread of this parasitic infection.
Greasy Pig Disease(Exudative epidermitis) is a generalized staphylococcal infection that affects young pigs.
The disease is also called exudative epidermitis which describes the oozing of fluid from the inflamed skin.

This document discusses common vices in poultry such as cannibalism, egg eating, egg hiding, and pica. It describes these vices and their causes. Cannibalism is when birds attack and eat each other, often due to overcrowding, genetic factors, or nutritional deficiencies. Egg eating can develop if birds break eggs accidentally and develop a taste for them. Egg hiding is a natural instinct that can occur if birds have too much freedom. Pica is eating unsuitable materials and can be due to phosphorus deficiency or parasites. Prevention methods include debeaking, isolation, improved diets, limiting freedom, and reducing stressors.
This document discusses several types of bacteria and viruses that can cause stomach infections, including E. coli, Campylobacter, Listeria, Vibrio, Toxoplasma, Salmonella, and Norovirus. It describes where each pathogen is typically found, the symptoms it causes, and precautions people can take to avoid infection, such as thoroughly cooking foods and washing hands. The key message is that following basic food safety and hygiene practices can help prevent the spread of dangerous stomach germs.
This document discusses common vices exhibited by livestock, including eye rolling, tongue rolling, self-licking and hair/wool eating, object sucking, intersucking between calves, and intersucking or milk suckling among adult animals. These vices are abnormal habits that can be caused by factors like genetics, confinement, or low-quality diets. Solutions aim to provide animals with free movement, balanced diets including salt mixtures, and separation from other animals exhibiting the behaviors.
This document discusses nutritional deficiency diseases in poultry. It begins by defining nutrition and describing macronutrients and micronutrients. It then explains that deficiencies can occur if nutrients are not present in feed or if birds cannot utilize available nutrients. Several specific deficiency diseases are described in detail, including symptoms and treatment options. These include slipped tendon caused by manganese deficiency, fatty liver hemorrhagic syndrome, and deficiencies of protein, vitamins A, E, D, thiamine, niacin, pyridoxine, biotin, folic acid, vitamin B12, choline, iodine, and zinc. The document provides an overview of important poultry nutritional deficiencies.

1. Common Diseases of Pigs
1. Salt poisoning
Salt poisoning in pigs occurs due to the excess intake of salt through the feed. An excess of ordinary
feeding salt in the ration or garbage feeding may result in this condition. The affected pigs show
symptoms of itchiness, thirst and constipation. They may become blind, deaf and completely
indifferent around the pen bumping into walls.
Providing water at all times liberally is most important in order to prevent the occurrence of the
disease. The feed should be replaced and providing salt in the ration should be completely stopped.
Mildly affected pigs will recover easily, whereas seriously affected ones may have to be isolated for
disposal.
2. Mercury poisoning
Mercury poisoning in pigs occurs as a result of feeding grains that have been treated with a
fungicide. Sudden death is observed in case of severe poisoning. The affected pigs will go off -feed,
become weak, suffer partial blindness and eventually become unconscious and die.
To prevent occurrence of mercury poisoning all surplus treated grains should be burned and ashes
buried deeply. A veterinary help may be required.
3. Head poisoning
This usually occurs in pigs which are let loose to feed on waste heap With old cans, tins and
batteries. Poisoned animals will show the symptoms of feed, pass. blood stained stools, stagger and
squeal. Jaw munching, convulsions, partial blindness and coma are observed in the final stages.
One to four ounces of Epsom salt (magnesium sulphate) can be provided to the suspected animals as
a first aid before seeking the advice of a veterinarian. Pigs should be prevented from having easy
access to the disposed cans, tins, etc. by discarding the tins in proper places.
4. Mould poisoning
Feeding of mould grains by the pigs result in their poisoning due to moulds. A decreased feed
consumption and rate of gain are the first visual symptoms. The affected animals show swelling of
2. external genitalia accompanied with weakness, staggering, yellow membranes and possibly death.
Pregnant sows may abort. Avoid feeding mouldy grains to the pigs. Especially to the pregnant or
breeding females. Keep the feeding trough clean and avoid chances of left over feed getting mouldy.
5. Lameness and paralysis
This condition affects both the new born and mature animals. Lameness and paralysis occur due to
arthritis, lack of calcium and phosphorus and vitamin E deficiencies. Nutritional deficiencies have
also been responsible for abnormal location. The environment and poor management of the pigs
also contribute to the impaired locomotion of pigs. Symptoms of lameness and paralysis are
fractures, swelling of joints, partial paralysis of both rear legs or an individual limb and shifting of
weight from leg to leg.
The control and treatment include provision of feeding a balanced ration and providing an ideal
environment to the pig for housing.
6. Heat stroke
Heat stroke may occur as a result of extremely hot weather, poor ventilation and lack of sufficient
fresh water during summer. Affected animals appear dull and seek shade and water. The body
temperature rises very high. It can be treated by applying wet cool packs to the back, sides and head
of the affected animal. In extremely Warm weather, well ventilated accommodation should be
provided. Fresh water should be available at all times. It is advisable not to have sows over fat at
farrowing time. Pigs kept outdoors must have shade and water.
7. Sunburn
Sunburn affects young pigs frequently and particularly white breeds due to excessive exposure to
sunlight. The symptoms are formation of large areas of pink, reddened skin which may develop
blisters. The pig staggers and sways. Treatment consists of providing shade and the application of
soothing medicines to the affected areas on skin. Sunstroke can be prevented by providing shade
and allowing pigs to have exposure to sunlight in increasing daily stages.
8. Constipation
Constipation means failing or having difficulty in passing , feaces. It is common in pigs of all ages and
occurs frequently in sows at farrowing time. Sudden changes in feed, over feeding, lack of exercise,
poor water supply and high temperature during the course of a disease may result in constipation.
Constipation at farrowing time can be prevented by feeding a bulky ration during the dry per iod and
the amount should be reduced as farrowing approaches. Provide plenty of water and add bran to
3. the ration bulky and thus avoid constipation. Mineral oils have also been successful in treating
constipation.
9. Mastitis
Mastitis is inflamation of the udder which leads to stoppage of milk production. The affected, glands
of the udder become swollen, hot and painful and the sow will not allow the piglets to nurse.
Common symptoms are fever, loss of appetite, constipation, and reduced milk flow. Proper f eeding
and management before and after farrowing lowers the occurrence of mastitis. Care should be taken
to avoid injuries to the udder and all wounds on the teats and glands should be cleaned and treated
with an antiseptic preparation. Regular cleaning and disinfecting of pen can control mastitis.
10. Metritis
Metritis is inflammation of uterus and occurs mainly due to insanitary conditions. Affected sows will
show signs of metritis at 1-3 days after farrowing. The sow will be off-feed, depressed, showing high
temperature and unwillingness to move. Prevention should include an examination and treatment of
the boar to prevent the spread of infection during breeding. Farrowing pens should be thoroughly
cleaned and disinfected.
11. Infertility and abortion
Infertility may be the result of infectious diseases, anatomical, hormone malfunctions and hereditary
defects. There may be parallel malfunctions in the boars also. Treatment of such animals is costly
and it is better to dispose of such animals. Abortions and still births may occur due to infections of
bacteria, fungi, virus and nutritional deficiencies.
12. Agalactia
Agalactia means partial or complete absence of milk flow Immediately after farrowing. It is most
commonly seen in gilts and young sows. The causes may be nutritional deficiencies, lack of water,
extreme heat or cold, constipation, mastitis, metritis, pneumonia, etc. Another important cause is
hormonal dysfunctioning for which veterinary help must be sought.
13. Anaemia
Anaemia is found commonly in young pigs of 2 -3 weeks old and is caused due to lack of iron and
copper in their bodies. Symptoms are paleness of the skin and in severe cases, a definite chalky
appearance is noticed. There is slow decline in health and the anaemic piglets are more susceptible
to other diseases than normal piglets. It can be prevented by providing iron containing foodstuffs
4. orally or by iron injections. Iron containing powders, pastes and liquids are also available in the
market which can be given twice a week in small amounts until the piglets are eating good amounts
of solid food. Over dose of oral or injectable preparations should be avoided.
14. White scours
The occurrence of white scours is a common problem among piglets and are a major cause of high
mortality of piglets in farrowing bums. They occur among the one week old pig lings and the affected
piglets are listless, weak and rapidly lose weight. A profuse yellowish white creamy diarrhoea is
evident. White scours is caused by bacteria and one of the best ways of preventing is to ensure that
the piglets receive colostrum milk (sow's milk within 4 -5 days of its litter is called colostrum and
contains antibodies). Strict sanitation should be followed and ensure that the piglets are born in a
warm, dry and draft free environment.
15. Para Keratosis
This is a non-inflammatory disease affecting tile skin of pigs and is caused by a high calcium and low
zinc in tile ration. Symptoms include lesions occurring on tile skin between tile hind legs and on tile
underside of tile stomach, crusty scales, low feed intake and poor weight gain. It is prevented by
properly balancing tile ration for calcium and zinc.
III. Non-contagious Diseases
The non-contagious diseases do not spread from pig to pig by contact. Only few animals will be
affected at a time. They are not very serious diseases as the affected animals usually recover if they
are detected promptly and proper treatment is given in time.
However, most of these diseases can also be prevented by good care, handling and management.
The non-contagious diseases are usually caused by parasites. These parasites may live outside tile
body or inside the body. Those living outside the body are called external parasites and those living
inside the body are called internal parasites.
A. External parasites
External parasites of pigs consist of a wide variety of insects such as lice, flea and flies having wings
or wingless, ticks and mites. These group of parasites have jointed legs and vary in size. The winged
insects frequently move from one host to other with the help of their wings, whereas wingless
insects or ticks are found adapted to their host. They have well developed claws on their legs or
mouth parts by which they can cling to the skin, burrow or cut and suck blood through skin. Mites
are found under the skin where they inflict injury and irritation. the symptoms include loss of blood,
5. irritation, scratching of body over any hard surface and reduction of feed in take. Raw bleeding areas
due to scratching invites winged insects, which often lay eggs on these wounds. These eggs develop
into larvae which search for fresh tissues and burrow deep inside the muscles. In swine the louse
and mange mites are the most common pests.
1. Hog louse
This parasite is found common in pigs and is often observed around the ears and on the backs and
sides of affected animals. Pigs constantly scratch and rub themselves and show irritation when the
lice puncture the skin and suck blood. Hog lice are capable of transmitting swine fever and usually do
not leave the body of a living pig other than by direct contact with other pigs.
Treatment and control
All pigs in a barn should be carefully inspected regularly for tile presence of lice. New additions to
the herd should be checked carefully for the presence of lice and dewonning all pigs in the barn
should be done. For treatment, p[ and Metthoxychlor preparations are frequently used for louse
control.
2. Mange mites
There are two types of mange mites that affect swine. The mites burrow into the skin and lay their
eggs. They are seen more often in winter months. The most common symptom is intense itching
which results in constant rubbing and scratching by the pits. The skin becomes quite reddended and
have a scurfy appearance.
Treatment and control
Spraying with Lindane is highly effective and should be repeated every 10-12 days to eradicate the
mites completely. Lindane should not be used on very young pigs or animals close to market weight.
The pig bam should be thoroughly cleaned and disinfected.
B. Internal parasites
Non-contagious internal parasites are worms usually found inside the host's body, especially in the
gut, stomach, intestine, bronchitis, muscles, connective tissues and urinary system. Large intestinal
round worms, nodular worms, whip worms and red stomach worms are the common intestinal
parasites.
6. 1. intestinal roundworms (Ascaris suum)
It is Large the most common parasite of swine and causes considerable economic loss to hog
production. Both adult and young pigs are affected. The young pigs become stunted and unthrifty
and have long coats of hair. They also become easily susceptible to pneumonic. conditions. The adult
pigs have damaged intestinal walls resulting in inflammation. The adult worms are very large,
creamy pink in colour and can be seen when passed with the faeces.
2. Nodular worms (Oesophagostomum delltatum)
The worm is small and is thread like in appearance. they damage the intestine by causing
inflammation and pinhead nodules in the intestine. Symptoms include low absorption of feed and
the pigs become thin and may have diarrhoea under severe infestation.
3. Whip worm (Trichuris trichiura)
This wonn commonly affects hogs and is shaped like whip and so called whipwonn. The damage
caused by the whip worm is not usually severe but harmful organisms easily enter the intestine due
to the inflammation of the intestine.
4. Red stomach worm (Hyostrongylius rubidus)
The red stomach worm is very small, reddish in colour and can be seen in the mucous of the
stomach wall. It causes considerable damage to the lining of the stomach which results in bleeding
and ulceration of the stomach lining.
Prevention and control of worms
Insanitary condition is the main cause of the incidence of these parasites. Therefore, regular cleaning
and proper disposal of manure and other waste materials should be carried out. Mix sodium flouride
in feed @ 0.75 to I % for control of ascarids. Cadmium oxide fed @ 0.015% in feed for three days is
effective in re4noving round wonns. Piperazine salt is quite effective in removing round wonns and
nodular worms. It can be given in feed or water to young pigs as well as sows just prior to farrowing.
Hygromycin and thiabendazole are also effective against nodular worms and rcd stomach worms.
C. Protozoan parasites
These parasites are very minute and cannot be seen with the naked eye. They may either live in the
tissues (pigs alimentary system) or in the blood of the pigs. Tissue parasites for example Eimeria sp.,
Isopora sp. and Bacillus coli invade different tissues and take nutrients from the host for their
7. growth. They affect the stomach and thus produce impaired stomach, loose stool, diarrhoea and
sometimes dysentery, whereas blood parasites, for example Trypanosoma sp,. Toxoplasma sp. etc.
invade different internal systems of pigs and destroy blood cells, produce fever, listlessness,
diarrhoea, jaundice and may even result in the death of the animal.
Prevention and control
Control measures include improved hygiene, over crowding of young piglets should be avoided, pens
should be cleaned regularly and feeding facilities should be improved. Control of intennediate hosts
like ticks should also be done. Ticks can be controlled by using different organo-phosphates or
organo-chlorinated com- pounds.
IV. Contagious Diseases
Some of the diseases of pigs spread rapidly in the herd and cause high mortalily. These diseases are
generally transmissible and are caused by virus, bacteria and fungi. The transmissible (i.e. infectious
or contagious) disease often affects the entire flock in stages and are, therefore, of vital concern to
the poultry keepers.
It is not always easy to determine how exactly a particular disease finds its way into a herd. but it is
certain that every outbreak originates from some infected animals which transmits the disease to
others. It is known that infectious diseases are generally introduced into healthy herds through
newly purchased animals. Wild birds. insects, animals and human beings also contribute to the
spread of the infection from one place to another The contagious diseases are usually caused by
virus and bacteria. The common contagious diseases are described below.
A. Viral diseases
1. Hog cholera (swine fever)
It is a highly, infectious virus disease affecting swine of all ages.
Symptoms
Young pigs usually show signs of the disease first. Depression, lack of appetite, a drooping attitude,
high fever, marked eye discharge due to conjunctivitis, early constipation followed by diarrhoea are
8. some of the earliest symptoms. As the disease progresses, a purple discolouration of the skin of the
belly is common.
Treatment and control
In early infection (3 -4 days) treat with anti-hog cholera serum. Vaccination before occurrence of
outbreak with swine fever vaccine will prevent outbreak. An amount of five doses along with 5 ml
cold sterile distilled water can be given to pigs of less than one year old.
2. Foot and mouth disease
Foot and mouth disease is a highly contagious disease of all cloven footed animals. However, in pigs
the disease is not usually as severe as in catlle.
Symptoms
Symptoms include appearance of small blisters in the mouth, causing soreness and a reluctance to
feed. There may be severe lameness in swine due to blisters around the top of the hoof and
between the toes or claws.
Treatment and control
There is no specific treatment for this disease. Timely vaccination of animals should be done. Other
treatments are following hygienic measures in the barn and washing the lesion with potassium
permanganate solution.
3. Transmissible gastroenteritis
It affects pigs of all ages and piglets under two weeks of age are highl y susceptible.
Symptom. This disease occurs as an explosive outbreak with a sudden onset of profuse, watery
diarrhoea. Most piglets under ten days of age will die within 2 -7 days after showing symptoms. It
usually appears in winter months. The nursing sow may also become ill, go off-feed and collapse.
Treatment and control
9. There is no specific treatment for this disease except that strict measures should be taken to isolate
and dispose of affected animals. Care should be taken during the introduction of new stock to a
herd. Building, etc. should be thoroughly disinfected.
4. Rabies
Rabies is a virus disease of all warm-blooded animals. It is mostly caused by dog or cat bites. The
virus is present in the dog's saliva which is transmitted through bites.
Symptoms
Affected pigs may salivate, walk backwards, have convulsions and eventually become paralysed.
There is no treatment for rabies. Keep the dogs and cats away from pigs, especially mad dogs.
.
6. Pig influenza
It is a viral disease affecting mostly young pigs.
Symptoms
The affected animals suffer from severe fever, loss of appetite, respiratory distress and discharge
from the nostrils and eyes are also noticed.
Prevention and control
The pigs should be provided with warm bedding and protected from cold. Vaccination must be
repeated every six months to be effective in swine.
B. Bacterial diseases
1. Brucellosis
Both the sow and boar are affected by brucellosis. It causes infected delivery in female animals and
infection of the reproductive organs in the male animals.
10. Symptoms
Swollen joints, lameness, abortion as early as 22 days and sterility may occur. Infertility and lack of
sexual drive in boars is also seen.
Treatment and control
It is better to dispose of infected animals from the herd. The boars should be carefully controlled
because the germs from the boar can be transmitted without the boar itself being ill.
2. Salmonellosis
This is a common contagious disease among swine caused by Salmonella bacteria. Spoiled feed,
sudden change in feed and insanitary conditions are the main secondary factors responsible for the
spread of the bacteria.
Symptoms
The common symptoms are dullness, high fever, dark red to purple discolouration of the skin along
the stomach and tips of ears. In acute endemic form, which is common in grower pigs, high fever
and a severe watery diarrhoea with a putrid odour and shreds of mucous from the intestinal wall are
observed.
Treatment and control
Infected animals should be segregated and treated. Water and feed should be checked. A thorough
clean up and disinfection should be carried out after the incidence of salmonellosis.
3. Anthrax
The disease is caused by bacterium Bacillus anthracis. It is a serious disease occurring sporadically
and affecting man and other animals. The disease germs can survive in the soil for years.
Symptoms
The affected animals show symptoms of high fever, inflamation of the throat, bloodstained fluid
coming from all the body opening, severe respiratory distress and dysentery. The affected animals
are usually found dead in the field.
11. Prevention and control
The carcass of tile animal suspected to have died of Anthrax should be burned and not buried. In a
field where anthrax has been found, as far as possible, cattle should be kept away. Anthrax spore
vaccine gives protection to health animals.
4. Pasteurellosis (bacterial pneumonia)
The disease is caused by a bacteria known as Pasturella nultocida. Sudden change in the
environment of the pig resulting in an additional stress to the animal's body is the favorable
condition for the occurrence of the disease.
Symptoms
Affected animals are depressed, huddle. breathe quickly, have a discharge from the nose and cough
frequently. Feed intake is reduced and many mamals are permanently affected, resulting in general
unthriftiness and poor growth.
Treatment and control
Provide proper environment for the pigs and avoid any feature that might cause extra stress. Isolate
all new stock before adding them in the herd. Follow sound management practices and provide good
sanitation, well ventilated barns and rich nutrition to the pigs to control the disease.
5. Swine erysipelas
It is an infectious disease of swine caused by a bacteria. The disease affects pigs of all ages. There are
two main fom1s-acute (septicaemic and skin) and chronic (joint lesions and heart lesions). Sows
which have farrowed recently are quite susceptible to an acute form and feeder pigs arthritic type
which later becomes chronic.
Symptoms
The disease is characterized by severe fever and appearance of typical reddish diamond shaped
discolourations on the body. In the acute septicaemic type, the pig is off -feed, has high temperature
and appears very sick. Dark reddish purple blotches appear along the neck throat, belly and inside
the thighs as well as ears. In the chronic form of the disease, swelling in joints, stiffness and
lameness is noticed. The joints most commonly affected are the back, elbow, stifle and hock.
12. Prevention and control
Affected animals should be isolated and treated with specific anti -swine erysipelas serum. Healthy
animals should be vaccinated against the disease in addition to treatment with antiserum.
Vaccination of young pigs should be done at 8-12 weeks of age and breeding stock twice a year
before breeding.
Disinfectants should be used frequently and liberally in pens and barns. Animals that die should be
properly disposed of.
6. Leptospirosis
It is an infectious disease of swine caused by a bacteria known as Laptospira icterolzaemorrhagiae.
The infection is usually spread by the urine of an infected animal.
Symptoms
Very small percentage of pigs suffer from acute trouble. Abortion in sows usually occurs 2-4 weeks
before pregnancy and is the only obvious symptoms of leptospirosis. Sometimes very weak piglets
are born at the normal time.
Prevention and control
A veterinary help should be sought to treat the infected animals. Wet and marshy pasture areas
should be fenced off to avoid the risk of exposure of swine on pasture.
7. Swine dysentery
Swine dysentery is a very common problem in the piggeries and is one of the worlds most serious pig
disease. It is caused by a bacteria known as Vibrio coli. Adults as well as young weaned pigs are
infected. The disease is spread through feed or water which has been contaminated by infected pigs
and carrier animals.
Symptoms
The first symptom includes a loose, light coloured to yellow diarrhoea. In a few days tile faeces may
become blood-stained with shreds of mucus and producing putrid odour. The affected pigs are
depressed, become quite dehydrated due to loss of body fluids and gradually loose weight due to
low feed consumption.
13. Prevention and control
A sound systematic sanitation programme will help in the prevention of the disease. New stocks
should be isolated for at least two weeks. Herd treatment through medicated drinking water is very
effective in controlling the disease. In recent years drugs such as Arsenic, Carbodox, Lincomycin,
Tylosin and Virginiamlycin have been commonly used for controlling this disease.
8. Tuberculosis
Tuberculosis in pigs is caused by a bacteria known as Mycobacterium tuberculosis. Young pigs get
infection through infected sows milk.
Symptoms
The disease affects all parts of tile body. Lesions are found throughout the body including internal
organs such as liver, spleen, kidneys, joints and lymph glands. Intermittent high fever is also often
noticed. The pig becomes very docile and sluggish and have good appetite.
Prevention and control
The first step in tile control of tuberculosis in a pig herd is to remove the source of infection periodic
testing should be done to remove and destroy the reacting animals and to keep the herd free of the
disease.
C. Protozoan disease
1. Balantidiosis
It is a protozoan disease of pigs and is caused by Balantiodium coli. The protozoa inhabit the caecum
and colon. Infection occurs through contaminated feed and water.
Symptoms
Symptoms include diarrhoea. dysentery, abdominal colic, vomitting, loss of appetite, muscular
weakness and faeces with blood and mucus.
14. Treatment and control
Control measures include: (i) treatment of affected animals and carriers, (ii) sanitary disposal of
infected faecal materials and (iii) prevention of feed and water contan1ination. The condition can be
treated with arsenical preparations, diguinol, neftin, chloro and oxytctra cyclines. Ayurvedic drugs
like hurchi and homeopathic drugs like meresol are also effective.
V. Prevention of Swine Diseases
Prevention is definitely better than cure and it is perhaps the only remedy available to pig farmers. It
is possible to prevent most of the non-contagious diseases. Contagious diseases can be prevented to
a certain extent through following timely preventive measures.
There are four important steps for removing cause of disease. They are (i) preventing the
introduction of new diseases, (ii) removing the existing sources of infection to break the disease
cycle, (iii) cleaning and disinfecting to reduce the number of disease organisms, (iv) practising good
management to reduce the effect of stress and to eliminate carrier animals.
A. Principles
Some of tile simple principles which can help in preventing most of the diseases to a great extent
and thereby reduce the loss due to diseases and make the piggery farm profitable are given below.
1. As far as possible, fanners rearing pigs should either raise their own fattening animals or buy only
from reputable and reliable disease free stock owners.
2. Animals with known history should be purchased.
3. Provide sufficient space, fresh air, good ventilation, sunlight, warmth and dry environment.
4. All pigs purchased should have proper identification marks.
5. Newly purchased animals should be isolated for 3 -4 weeks before they are introduced into the
herd.
6. House them in properly elevated, dry and hygienic rooms and buildings with good flooring and
surface drainage, all weather proof roof, easy to keep clean, not dirty, dry litter and guaranteeing a
constant temperature should be selected for boars, sows and piglets.
7. Follow strict hygienic and sanitary methods. Clean pens and buildings thoroughly and regularly
and dispose of dead animals by sanitary means.
15. 8. The animals must be fed with good quality of balanced feed according to their age, sex,
physiological status and functions performed. Provide plenty of clean fresh water to drink.
9. All the pigs in the pen should be inspected daily to detect dull and unthrifty ones which may
apparently be not in sound health, and suspicious ones should be immediately isolated for special
care and attention.
10. The pig run whether enclosed or open should be clean.
11. Boars should be purchased and brought to the farm before they are of breeding age.
12. Animals which keep on scratching their bodies without eating their feed should be picked out
and examined for the presence of ectoparasites (lice, fleas, mange, etc). They must be removed by
dusting or spraying the medicines.
13. Animals which have diarrhoea and those loosing weight should be segregated and examined for
the presence of endoparasites. They must be dewormed regularly as per the recommendations .
14. Discourage, if not check, the entry of visitors into the pen and keep them away from baby pigs. A
few pairs of rubbed boots kept at the entrance for the visitors will help for entering the pen in case
of necessity.
15. Isolate dull and apparently sick animals into the segregation shed and dispose of dead animals
immediately.
16. Observe animals frequently and give extra care at weaning, castration and vaccination.
17. Outside yards and run-ways that have been occupied by disease affected swines cannot be made
safe by disinfection and should be left vacant for atleast a year. All litter and manure should be
removed so that the surface of the soil will be exposed to direct sunlight.
18. Consult the local veterinary doctor from time to time and arrange for timely preventive
vaccination of all animals against swine fever and other diseases before their occurrence.
B. Practices
1. All newly purchased animals or those brought back from shows and exhibitions, should be
quarantined and kept isolated for 3 -4 weeks before they are introduced into the herd.
2. Segregate tile young pigs, from older pigs.
3. Visitors should not be allowed to enter piggery pens and houses.
4. Provide plenty of shade, small stuffy housed are a nuisance
in hot weather. Free air circulation under the shade is important.
5. Sweep out thoroughly feeders, water troughs, runways and passages. Scrub with hot water and
lye, using one litre of lye in 45litres of cold water.
16. 6. Apply a heavy, even coating of lime wash containing a reliable disinfectant to the floors, walls,
partitions, feeders, water troughs, and gutters.
7. In making lime wash use 0.45 kg of lime in 4.5 litres of water and as disinfectants vary greatly in
strength, they should be added according to the directions given on the container.
8. Remove manure completely from the floor and walls of the pen by thorough scraping.
9. Bum all scrapings and sweeping and do not allow them to scatter around the building.
10. Empty and scrub individual drinking bowl on troughs with a reliable disinfectant solution.
11. Remove all manure, straw-bedding and other refuse from the neighbour hood of the building.
12. To clean and disinfect an earthen floor, it is suggested that the top 15 cm of soil be removed and
replaced with 15 cm of fresh soil obtained from clean source.
13. Protect feed and water from being contaminated with manure and urine and from the droppings
of birds and rodents.
14. Dampness and overcrowding should be avoided by improving drainage and providing ample
living space. The pen should receive plenty of direct sunlight.
15. The animals should be fed adequately with well balanced rations to build up resistance against
disease.
16. Keep livestock and feed trucks away from those areas to which pigs have access.
17. The sow should be cleaned and washed before being introduced into the farrowing pen.
18. Regular deworming in affected area or herd should be done.
19. Correct feeding of the sow both before and after farrowing is necessary to ensure a litter of
strong healthy piglets.
20. The pig keepers in the villages should co-operate with one another and act collectively in taking
the necessary preventive measures. If an infectious disease breaks out in a herd, the above
additional precautions should be taken.
C. Preventive measures
The common methods of prevention of diseases are the use of disinfectants, vaccines and
fumigation. They are briefly described here.
1. Disinfectants
17. Disinfectants are chemicals used to disinfect the utensils, implements, the whole house and Its
surroundings. Some of the most common disinfectants which are available in the market are crest,
Lysol, Lye, Izal, lime and Creolin.
Solutions of these compounds for disinfecting houses and equipments are given below.
a. Lysol: Used as a 1 -2 % solution, it is an effective general disinfectant, suitable for-instruments,
equipments, foot bath, etc.
b. Lye (CaOH solution): About 2-5% solution will destroy most of pathogenic organisms and their
spores. Highly corrosive to skin.
c. Lime powder: An inexpensive general disinfectant, can be used as a white wash to walls; also used
in combination with 2-4 % Cresol or I-2% Lye as an economical and effective disinfectant.
To prepare white washing mixture, dissolve 22.5 kg hydrated lime in 27 litres of waters for several
hours and mix it with 7 kg of salt dissolved in 21litres of water.
2. Vaccination
Vaccination is a common method of preventing the diseases especially those for which suitable
treatment is not available.
Vaccines are now being used for swine fever, foot and mouth disease and rinderpest. These are
given in the table-1.

3. Fumigation
Fumigation of the buildings in the all in and all out (system of raising pigs have been found successful
in preventing occurrence of diseases. The most common fumigant is made from potassium
permanganate and formalin. For each 100 cu.ft of room space, use one ounce of formalin (37%
solution) and 0.6 ounce (17.5 g) of potassium permanganate. Mix the two chemicals in an enameled,
ceramic or plastic vessel. The wall and pen surfaces should be wet when the fumigation process is
started. The building should be tightly closed for 24 hours. Fumigated buildings should be well
ventilated for at least a day. Farrowing houses should remain closed and empty of livestock and feed
two weeks before sows are admitted for farrowing.
VI. Conclusion.
Economical piggery production demands healthy livestock. One of the worst hindrances in livestock
rearing is disease, and to keep the livestock free from disease is equally difficult. Hence the practice
is to keep the incidence of diseases low among livestock. To keep the disease incidence low, some of
the general aspects of preventive measures discussed in this booklet have to be kept in mind and
practised. Successful pig production generally depends on the efficient disease control. The aim of
fanners should be to prevent diseases and parasites rather than merely treating after they occur.
"Prevention is better than cure" and also the better the sanitation and management practices, the
less will be the occurrence of parasitic and other diseases among livestock.
