The document discusses dairy cattle feeding management over five phases: 1) early lactation 2) peak dry matter intake 3) mid to late lactation 4) dry period 5) transition period. It provides guidelines for each phase, including nutrient requirements, feeding practices, and goals of optimizing milk yield and minimizing costs. The largest input cost is feed, representing 60-70% of total costs. Proper feeding is crucial for high milk production and reproductive success.

दूध देने वाले पशुओं का पालन हजारों वर्षों से होता आ रहा है। प्रारंभ में, इनका उपयोग निर्वाह खेती के लिए खानाबदोश द्वारा किया जाता था। जब भी पूरा समुदाय दूसरे देश में स्थानान्तरण करता था ये उनके साथ होते थे। जानवरों की रक्षा करना और खिलाना यह जानवरों और चरवाहों के बीच सहजीवी सम्बन्ध का एक बड़ा हिस्सा था।
हाल के अतीत में, कृषि करने वाले समाज के लोग दुधारू जानवरों को कुटीर उद्योग के रूप में घरेलू और स्थानीय (गांव) में दूध की खपत के लिए पालते थे। जानवर कई प्रकार से इनके लिए उपयोगी हैं, उदाहरण के लिए जवानी के समय इनके लिए हल खींचते हैं और मरणोपरान्त इसका मांस उनलोगों के लिए उपयोगी होता है। इस मामले में आम तौर पर जानवरों को हाथ से दुहा जाता थ और इनके झुंड का आकार काफी छोटा होता था, इसलिए सारे पशुओं के एक घंटे में दुह लिया जाता था - करीब दस प्रति दूध दुहने वाले. इन कार्यों को दूध दुहने वाली (दूध दुहने वाली औरतें) या दूध दुहने वाला पूरा करते थे। डेयरी शब्द की उत्पत्ति मध्य अंग्रेजी के शब्द डेयेरी से हुई है, डेये अर्थात् (नौकरानी या दूध दुहने वाली महिला) और पुरानी अंग्रेजी का शब्द डेगे (रोटी गूंथने वाला).
औद्योगीकरण और शहरीकरण के साथ, दूध की आपूर्ति ने वाणिज्यिक उद्योग का रूप ले लिया है, गोमांस और डिब्बाबंद से बिल्कुल भिन्न विशिष्ट नस्लों वाले मवेशियों को
Dairying is an important source of subsidiary income to small/marginal farmers and agricultural labourers. In addition to milk, the manure from animals provides a good source of organic matter for improving soil fertility and crop yields. The gobar gas from the dung is used as fuel for domestic purposes as also for running engines for drawing water from well. The surplus fodder and agricultural by-products are gainfully utilised for feeding the animals. Almost all draught power for farm operations and transportation is supplied by bullocks. Since agriculture is mostly seasonal, there is a possibility of finding employment throughout the year for many persons through dairy farming. Thus, dairy also provides employment throughout the year. The main beneficiaries of dairy programmes are small/marginal farmers and landless labourers.To know more please visit us www.growelagrovet.com
Poultry meat is an important source of high quality proteins, minerals and vitamins to balance the human diet. Specially developed varieties of chicken (broilers) are now available with the traits of quick growth and high feed conversion efficiency. Depending on the farm size, broiler farming can be a main source of family income or can provide subsidiary income and gainful employment to farmers throughout the year. Poultry manure is of high fertilizer value which can be used for increasing yield of all crops.
The advantages of broiler farming are
a) Initial investment is lower than layer farming
b) Rearing period is 5-6 weeks only
c) More number of flocks can be taken in the same
shed
d) Broilers have high feed conversion efficiency i.e. the amount of feed required for unit body
weight gain is lower in comparison to other livestock
e) Faster return from the investment
f) Demand for poultry meat is more compared to sheep/goat meat

Dairy feed needs to provide Energy: It is as the fuel for a machine and it is needed for milk production.
Protein: The material to build up the muscles, fetus and the milk production.
Minerals: They are needed for growth of the bone and the fetus as well as for the milk production.
Vitamins: Intervene in the metabolism and the digestion of feeds.
Water: Water is needed for maintenance and to produce milk. Water contains about 90% in the milk.
Modern hybrid layers can be reared successfully in floor and cage brooding systems in developing countries. However, they need more careful management than village chicks, which are better able to cope with temperature fluctuations.
Prior to chick arrival, it is important to clean and disinfect the cages or the floor brooding area. The brooders should be set up the day before delivery, at 34 to 36 °C for cage brooding or 35 to 36 °C for floor brooding. Drinkers need to be full or the drinking system in operation, to encourage birds to drink. If nipple drinkers are used, the water pressure should be reduced so that birds can see the drop of water hanging on the drinker. Feed should be placed on paper if birds are reared in cages. Feeders on the floor should be filled and kept under high light intensity for 20 to 22 hours per day for the first week, to attract the birds.
Most people who are involved in commercial egg production,have seen management guides for different strains of layers before and may think “if you have seen one, you’ve seen them all”. Others take the contents more seriously and expect frequent updates to find specific data which apply to the current generation of layers and current management practices.
Newcomers in the business may need more detailed explanations than can be presented in this compact format.
We hope that each reader will find some useful information,to confirm proven management practices or to stimulate improvements.
Poultry egg and meat are important sources of high quality proteins, minerals and vitamins to balance the human diet. Commercial layer strains are now available with traits of high egg production and high feed conversion efficiency. Superior germplasm of chicken have been developed by both public and private sectors which met the requirement of Indian Poultry Industry. Depending on the farm-size, layer (for eggs) farming can be main source of family income or can provide income and gainful employment to farmers throughout the year. Poultry manure has high manure value and can be used for increasing yield of all crops.
Poultry is one of the fastest growing segments of the agricultural sector in India today. India has emerged on the world map as the 3rd largest egg producer (56 billion eggs) and annual growth rate in egg production approximated 6% per year (Source; Report of the Working Group on AH & dairying, 12th Five Year Plan). The current strength of layers in India is estimated to be 230 million and the annual percapita availability of eggs has increased from 7 eggs in 1961 to 52 eggs in 2010. However, the present availability is far below the ICMR recommendation of 180 eggs per capita per annum.In the poultry industry, value added products utilizing poultry eggs, culled birds for human consumption have been developed. However only 6% of the eggs produced in the country are converted into processed egg products mainly for export.To know more please visit us www.growelagrovet.com
If you plan to start or have started raising chickens for egg production, you need to understand flock production capabilities. You need to know how to gauge the number of eggs your flock can produce and be aware of the variables that affect egg production. You should be able to identify which hens are laying and determine why your hens are not laying. By having a firm grasp of these factors, you will help ensure the success of your flock.
In this article it has been described :
Identify the threats to our poultry and how disease agents
might enter a poultry farm
Identify the costs of diseases and their prevention
Define the three principles of biosecurity:
Segregation & Traffic control
Cleaning

Identify biosecurity risks present in a poultry farm
This manual is a brief guide to preventing, diagnosing and controlling poultry diseases. All major poultry diseases are discussed in detail. The description of each disease includes information about its cause, the susceptibility of poultry species, ways the disease is transmitted, clinical signs and lesions, how the disease is diagnosed, and ways to treat it. There are colour photos to aid in disease identification. There is additional information on the nature and cause of disease and on sanitation practices, and a glossary of common terms. The book is fully indexed so that diseases can be found by both their formal and common names
Layer poultry farming means raising egg laying poultry birds for the purpose of commercial egg production. Layer chickens are such a special species of hens, which need to be raised from when they are one day old. They start laying eggs commercially from 18-19 weeks of age. They remain laying eggs continuously till their 72-78 weeks of age. They can produce about one kg of eggs by consuming about 2.25 kg of food during their egg laying period. For the purpose of producing hybrid eggs layer, consider the various characteristics of cock and hen before breeding. There are various types of highly egg productive layer breeds available throughout the world.
Poultry production can be divided into four sectors:
1. industrial and integrated, 2.commercial high bio-security, 3. commercial low bio-security, 4. village, and family or backyard poultry. The focus here is largely on sectors 3 and 4 but there may be some overlap.
‘Family poultry’ as defined by the International Network for Family Poultry Development, covers sectors 3 and 4 which encompass small - scale poultry production.
There are numerous poultry handbooks which cover sectors 2 and 3, but this hand book has attempted, in two manuals, to cover mainly sector 3 while not ignoring the great importance of bio-security particularly in the face of highly pathogenic avian influenza (H5N1). It is envisaged that, given time, some producers, now in sector 3 may move into sector 2.
The two manuals are pitched at two different levels.
The Trainer’s (instructor) manual assumes that the trainer has qualifications and/or experience in a branch of agricultural science but not necessarily in poultry production. Some of the material included is beyond that necessary to give an initial course in poultry production but may be useful as the farmer progresses from sector 3 to sector 2. The trainee’s manual has numerous illustrations and is aimed at a lower level than for the trainer.
The farmer may be interested in starting a poultry enterprise is already producing poultry in a small - scale commercial or semi-commercial (opportunistic) situation but would like to make poultry farming more permanent. The course will allow the farmer to increase his/her knowledge and skills and to become aware of a number of important issues (e.g. managing the environment, disease surveillance) of his/her enterprise.
In order to minimise repetition, there is some material in the trainee’s manual that is not in the trainer’s manual. Trainers should familiarise themselves thoroughly with both manuals.
The third manual is for the millions of families, worldwide, in low – income,
developing countries who keep backyard poultry, mainly unmanaged, with few inputs, but nevertheless are of great importance by providing, some security, income and high – quality protein. It is hoped that this manual will make families aware of the possibility of improving output with a minimum of input.
Much of the information has been taken from a range of sources as well as the author’s own experience of working in several developing countries over 25 years.
Ideally, there should be a small-scale demonstration unit or a poultry farm available so that the trainees can see, first hand, and better understand the main points in these manuals and observe how commercial poultry production should be practised.

Proper vaccination is an essential part of a good poultry management program and for the success of any poultry operation. Effective preventive procedures such as immunisation protect hundreds of millions of poultry worldwide from many contagious and deadly diseases and have resulted in improved flock health and production efficiency.
Immunization cannot be a substitute for poor bio-security and sanitation. Thus, vaccination programs may not totally protect birds that are under stress or in unhygienic conditions. The primary objective of immunizing any poultry flock is to reduce the level of clinical disease and to promote optimal performance. Certain vaccines may also have an impact on human health (i.e. Salmonella vaccines).
For breeders – we also want to accomplish some additional goals:
A. Protect the bird (as a pullet and hen) against specific diseases.
B. Protect the progeny of the hen against vertical transmission of disease.
C. Provide passive immunity to progeny.
This color atlas of poultry diseases .This is very useful guide for poultry farmers & poultry practicing professionals.The atlas contains colour photographs demonstrating the overall pathology of birds. The book includes more than 50 diseases from avian infectious pathology and a similar number from non-infectious pathology.There are both classic and well known diseases and new and little known diseases. The book is designed for veterinarians, veterinary students, poultry farmers and poultry specialists.
