Cattle Ticks and Risk Factors Related to Tick Infestation of Livestock in Per...Agriculture Journal IJOEAR
Tick-borne diseases are a global public health problem, particularly in sub-Saharan Africa, where most of the disease is caused by malaria and many other diseases of viral, parasitic or bacterial origin. This study aimed to identify the bovine tick's species in cattle farms and to determine possible risk factors related to tick infestation in Abidjan district and Azaguié commune. Thus, in July 2019, thirteen (13) herds distributed in these localities were visited for tick sampling and to conduct epidemiological investigations. At each visit, ticks were harvested from 15 cattle per herd. All the farms visited were infested with ticks. 96.92% of sampled animals had ticks. A total of 1796 ticks were collected of which 89.42% (1606) were adults, 10.41% (187) were pupae and 0.17% (3) was larvae. Two species of ticks have been identified, Amblyomma variegatum with 25% of the population and Rhipicephalus (Boophilus) microplus with 75%. 96% of the cattle were infested by ticks of the species R. (B.) microplus and 56% of the cattle were infested by ticks of the species A. variegatum. The co-infestation of cattle by the two identified species was 53%. The distribution of the sexes showed that in the species A. variegatum, males were more numerous (13.44% for males and 8.76% for females). However in the species R. (B.) microplus, females were more numerous (5.08% for males and 62.3% for females).The analysis of risk factors associated with tick infestation in cattle has shown that factors such as Undefined parks, Type of pasture, Training in the use of acaricides and Presence of wild animals contribute to major ectoparasite infestations in cattle. Tick samples collected from peri-urban farms in the district of Abidjan and the locality of Azaguié as part of this study, indicate that the relatively recent introduction of the species Rhipicephalus (Boophilus) microplus presents a threat to animal and human health.
Hydatidosis of camels and cattle slaughtered in sokoto state, nothern nigeriaAlexander Decker
This study examined 189 camels and 285 cattle slaughtered in Sokoto, Nigeria to assess the prevalence of hydatidosis. The study found:
1. Hydatid cysts were found in 44.4% of camels and 1.8% of cattle examined, with the prevalence significantly higher in camels.
2. The majority of cysts in camels were found in the lungs (93.2%) while most cysts in cattle were found in the liver (80%).
3. Most cysts recovered from camels and cattle were small, and there was no association between cyst size and infected organ.
The results indicate hydatidosis is common in the study
This document summarizes a study that assessed ectoparasite infestation on goats and domestic fowls in Vunania, Ghana. Approximately 76% of goats and 84% of domestic fowls were found to be infested with ticks, fleas, mites, and lice. A total estimated population of 4,110 ectoparasites was found on goats, and 9,688 ectoparasites were found on domestic fowls. The most common locations of infestation varied between parasite type and animal. The results suggest rainfall influences ectoparasite activity and survival. Further control efforts are needed to address the health effects on livestock.
Hepatic and Rumenal Worms Infestations of Cattle in Vina Division (Adamawa – ...AI Publications
The main objective of this work is to describe a preliminary epidemiological account of major hepatic and rumenal distome worms of cattle in Vina Division, Adamawa Region of Cameroon. A total of 1361 cattle dung specimens and 450 blood samples were collected between April 2018 and March 2019 in 06 subdivisions within Vina Division. The dung and blood samples were placed in a cooler. The cooler was immediately transported to the medical and veterinary laboratory of Special Mission of tsetse fly Eradication where samples were kept cold at +4°C for at most 48 hours. The qualitative method of concentration of worm eggs by simple sedimentation was performed.Blood parameters were measured using a haematology automated system. Of the 1361 cattle dung specimens examined, 424 presented distome eggs giving a prevalence of 31.15 %.These were Fasciola gigantica, Paramphistomum daubneyi and Dicrocoelium hopes eggs.All cattle age groups were infected by worms. In terms of prevalence, medium cattle were found to be the most infected. In lean cattle the parasitic loads of F. gigantic and D. hopes were high and then decreased as the health of the animals improved. All cattle breeds were infected by at least one of the worm species. Bokolo and Djafoun were most infected by F. gigantica, while Holstein and Aku were more influence by P. daubneyi. Goudali breed is the one that has undergone the least parasitic pressure. Male cattle were more infected than females, but females exhibited higher mean intensity of infestation. Older cattle were more susceptible to F. gigantic and D. hopes infection while Adults were more infected by P. daubneyi. Whatever the parasite considered, parasitic load progressively increased with the age of the cattle. The number of cattle infected by P. daubneyi and D. hopeswas greater in the rainy season unlike F. gigantic infection which was more recurrent in the dry season. Mbe locality had a high prevalence of F. gigantica and P. daubneyi. However, Ngaoundere 1, 2 and 3 presented the highest mean intensities for all worm species. Prevalence and mean intensities of cattle have been more important in extensive livestock status. All the worms were encountered all year round, except for November and December 2018 where D. hopes was absent. Polyparasitic cases were observed. Nevertheless, bispecifics associations were most frequent. Mean Corpuscular Volume, Platelet Concentrations, Mean Corpuscular Haemoglobin, Total Leucocytes Count and Granulocytes mean values were higher in cattle with significant parasitic loads while Total Erythrocyte Count and Packed Cell Volume were low. Today, it is well established that distomatoses represent one of the major parasitoses of cattle in Vina Division of Cameroon.

A review on the diagnostic and control challenges of majorAlexander Decker
This document discusses the diagnostic and control challenges of major tick-borne diseases that affect cattle, including babesiosis, anaplasmosis, and theileriosis. It describes the causative agents, transmission cycles, clinical signs, and economic impacts of these diseases. It notes that while new diagnostic techniques like PCR and improved serological tests have been developed, limitations remain. Historically, control has relied on intensive acaricide use but this is not always cost-effective or sustainable given increasing acaricide resistance in ticks. More integrated control approaches and improved diagnostics are needed.

A cross sectional study was conducted from November 2015 to April 2016 in Jimma zone of Oromiya region, to determine the prevalence of abomasal nematodes of sheep slaughtered at Jimma municipal abattoir. A systematic random sampling technique was applied to select the sheep. Abomasum of sheep was incised following the standard procedures. A total of 387 abomasums were incised and using standards of parasite identification methods two genera of nematodes were identified with an overall prevalence of 78.29%. The prevalence of Haemonchus contortus and Trichostrongylus axei was 66.67% and 53.5%, respectively. A statistically significant difference (P > 0.05) was not found between origins in prevalence of these parasites. However, a statistically significant difference (P < 0.05) was noticed between the level of the prevalence and different body conditioned animals. The highest prevalence was in poor body condition (97.26%). The overall mean worm count was 5334.97 and the mean worm count of specific nematode were 675.19 and 690.82 for Hemonchus and T. axei, respectively. The great majority of the infected sheep was with light, moderate and heavy degree of infestation. The current study epitomized that the prevalence of nematodiasis was high and consequently; sustainable control programs should warrant.

This study determined the seroprevalence of brucellosis in small ruminants in and around Bahir Dar, Ethiopia from 2008-2009. A total of 500 serum samples from sheep and goats were tested using the Rose Bengal plate test and complement fixation test. The overall prevalence of brucellosis was 1.2% by the Rose Bengal plate test and 0.4% by the complement fixation test. All positive samples by complement fixation test were from adult female goats. While the prevalence was low, the study concluded that brucellosis exists in the area and positive animals should be eliminated to control spread of the disease in small ruminants.
Ongoing disease control programmes in indiaBhoj Raj Singh
Animal Husbandry, Dairying and Fisheries sectors play an important role in the national economy and in the socio-economic development of the country. Livestock sector alone contributes 4.11% towards overall National GDP and 25.6% of total Agriculture GDP. The biggest impediment to growth of this sector, however, is the large-scale prevalence of diseases such as Foot and Mouth Disease (FMD), Hemorrhagic Septicemia (HS), Brucellosis, Black Quarter (BQ) in cattle, Enterotoxaemia, Peste des Petits Ruminants (PPR) & Sheep-Goat Pox in sheep and goats and Swine Fever in pigs, which drastically affect the productivity of animals. The presence of this disease not only deters the domestic economy but also foreign investment in the livestock sector. Although India have been free from disease like Rinderpest, Contagious Bovine Pleuropneumonia (CBPP), Bovine Spongiform Encephalopathy (BSE), presence of other economically important disease still threaten the very roots of livestock sector. This presentation describes various control programs that have been introduced by the Government of India, nationwide for controlling the infectious diseases of animals that have been or should be targeted for eradication or elimination, direct and indirect benefits from control programs, drawback issues and opportunities for the future.

FMD: Menace in India
Discusses problems of FMD Control in India like:
Lack of faith in farmers and veterinarians that FMD can be controlled with vaccination (due to repeated failure of vaccines in quality and vaccination failures resulting in FMD outbreaks).
Lack of infrastructure facilities for maintaining the cold chain and efficient transport to the vaccination site.
Lack of human resources for handling/ vaccinating livestock.
Needs for further researches on diagnosis (Pen-side), disinfection, vaccines and vaccination (affording at least a year immunity, quality vaccine etc.) and control strategies.
No-timely investigation or excessively delayed investigation of FMD outbreaks especially those occurring after vaccination.
Transparency in vaccine quality monitoring and vaccine purchases.
Fear in veterinarians for reporting FMD in their area of operation.
False statistics of the disease and vaccination.
No legal punitive action against suppliers of substandard FMD vaccines even after the supply of multiple substandard batches of vaccine.
This study examined the seroprevalence of brucellosis in small ruminants in Dire Dawa, Ethiopia. Blood samples were collected from 159 sheep and 265 goats and tested for Brucella antibodies. The overall seroprevalence was found to be 2.6%, with 1.9% in sheep and 3.0% in goats. There was no significant difference in prevalence between age groups, sexes, or species. Most respondents (66.7%) lacked awareness of brucellosis's zoonotic importance. Many flock owners (72.2%) drank raw milk and most (96.3%) handled fetal materials with bare hands, exposing them to Brucella infection
This document discusses brucellosis, a globally important zoonotic bacterial disease. It is caused by Brucella species and transmitted from animals to humans through contact or consumption of infected animal products like unpasteurized milk. In animals it causes reproductive issues like abortion. In humans it causes non-specific flu-like symptoms. Diagnosis involves isolating the bacteria or detecting antibodies. Treatment is difficult due to antibiotic resistance. It has significant public health and economic impacts especially in developing countries where control measures are not well implemented.

This document summarizes information about African swine fever (ASF) in smallholder pig systems in Africa, including:
1) ASF is caused by a virus that can survive for long periods outside a host. It has no vaccine and causes high mortality in pigs.
2) ASF transmission cycles involve domestic pigs, wild boar, soft ticks, and human activities. It is endemic in many African countries and has spread to Europe and Asia.
3) Controlling ASF is challenging due to multiple transmission cycles and lack of vaccines. Key control strategies include early detection, movement restrictions, culling, and improving biosecurity through practices like sanitation and restricting food waste access.

This document discusses avian influenza in Indonesia. It provides statistics on Indonesia's poultry population and production systems. Smallholder backyard farms account for 20% of production while commercial farms make up the remaining 80%. Avian influenza has been confirmed in 29 out of 33 Indonesian provinces. The government's national strategic plan aims to control avian influenza at its source in animals through culling, compensation, vaccines, and improved biosecurity. The plan also focuses on risk communication and strengthening human pandemic preparedness.
1) Researchers identified a new genotype (genotype XXIII) of the African swine fever virus (ASFV) in domestic pigs from Ethiopia. 2) Analysis of partial p72 and full p54 gene sequences showed this new genotype shares ancestors with genotypes IX and X found in Eastern Africa. 3) Analysis of the central variable region of the B602L gene also identified novel amino acid repeats not previously characterized.
Toxocara vitulorum infection has been reported to have a cosmopolitan distribution in whole of the tropical and subtropical regions of the world with a moderate, continental climate. Parasitic diseases of dairy animals are a universal problem and considered one of the major obstacles in health and production performance of animals. Retarded growth, poor production of milk, meat, poor quality of skin and hides are known harmful effects of parasitic infections in bovines. This study was aimed to determine prevalence of Toxocara vitulorum in Ambo area Sankalefaris peasant association in cattle of different Age and sex group. Across sectional study was conducted to investigate the prevalence of bovine ascariasis infection on 243 animals in Senkale Faris peasant association in Ambo district west Shewa zone. To achieve this; floatation techniques was employed. Based on this method about the overall prevalence was 243(63%) of which ages, and sex was a determinant factor Toxocara vitulorum. The known prevalence with age and sex category was <3 month,122(68%), 3-6 month, 70(61%), 6 month 30(12.3%) and 1 year 21(8.6%) p-value 0.000, from this we can say age of cattle has highly significant on enhancing the disease. In conclusion the result of the present study has revealed that there is high prevalence of ascariasis in calves, hence, appropriate treatment, control and owner’s awareness, should be implemented so that to increase the productivity of

Persistence of African swine fever outbreak in a farm in Kaduna, Nigeria.David Dazhia Lazarus
This document summarizes a study on the persistence of African swine fever outbreak in a farm in Kaduna State, Nigeria. The study found that five breeder houses on the farm were wiped out within a week of the outbreak. Testing of samples from the single surviving piglet confirmed the presence of African swine fever virus through serology and PCR analysis. The outbreak demonstrates that African swine fever continues to be a problem in Nigeria due to unregulated pig movements and lack of effective control strategies. Comprehensive surveillance, improved biosecurity, and government support are recommended to improve management of the disease.

- Higher prevalence was seen in male turkeys compared to females. Multiple parasitic infections per turkey were common.
- The small intestine was the most common site of infection for nematodes and protozoa. No parasites were found in the proventriculus.
Bovine Mastitis due to Coliform Bacteria, and Susceptibility to Antibiotics, ...Premier Publishers
This study was aimed at determining the prevalence of coliform bacteria in bovine milk in Plateau State of Nigeria and their antibiotic susceptibility patterns. A total of 640 milk samples were collected aseptically and 160 questionnaires from where data such as breed, age, parity, lactation stage, floor type, and husbandry system were analyzed. Cows without clinical mastitis were subjected to California Mastitis Test to determine the presence of subclinical mastitis. Bacteriological assays and antibiotic susceptibility tests were conducted according to standard guidelines. Subclinical mastitis with a prevalence of 63.8% was more prevalent in cows than clinical mastitis. Overall, the Friesian breed had the highest mastitis prevalence of 85.7% compared to White Fulani (which is indigenous in Nigeria). Cows aged within 2-4 years old had the least mastitis prevalence of 55.2%. Coliforms isolated from milk samples included E coli, K. pneumoniae, K. oxytoca, C. freundii, E. aerogenes, E. cloacae, and S. marcescens, with E coli having the highest prevalence of 44.8%. The most resistant antimicrobial agent was Streptomycin with 79% prevalence. The principle of One Health approach which targets the environment, animals and humans should be considered important. Good hygienic measures should be intensified among pastoralists.
Toxoplasmosis in Farm Animals in the United StatesHVCClibrary
This document provides an invited review on the prevalence of Toxoplasma gondii in farm animals in the United States. It discusses how T. gondii is one of the most common parasitic infections in humans and animals worldwide. Food animals like pigs, chickens, lambs and goats can become infected through environmental exposure to T. gondii oocysts, resulting in meat containing tissue cysts that can infect consumers if undercooked. Surveys have found T. gondii infection to be common in food animals in the US, especially pigs. The review examines prevalence studies in these various food animals and discusses the challenges in determining the relative contribution of food versus environmental transmission of T. gondii to humans
Emerging parasitic infections in goats in pastoral systems in kenyaAlexander Decker
This document summarizes a study on parasitic infections in goats in pastoral systems in Kenya. A total of 832 goats from 76 herds across 5 provinces were sampled to analyze tick infestation and strongyle egg counts. The overall mean tick count was 21 ticks per animal, with some districts having much higher counts. The overall strongyle egg count was 545 eggs per gram of feces. Both ticks and strongyle parasite infections were widely prevalent and at high levels. The study suggests these parasitic infections will become more economically important for pastoralists due to increasing pressure on grazing land and water sources. Further research is needed to understand disease transmission and impacts, and develop effective control strategies.
The purpose of the study was to know the conduct of pig farms, the state of cysticercosis and its consequences on the quality of production of pigs in N'Djamena, Chad. Three methods were used: (i) the transverse and retrospective survey for information related to the conduct and hygiene in 64 farms sampled in eight blocks belonging to three districts, (ii) the langueyage to observe cysts and (iii ) documentary investigation for total seizures in the slaughter house over six years. All farms had barns which were considered in good condition (66%). However, most of the farms (91%) did not practice permanent confinement. The majority (81%) accounted for two per day of food distributions to pigs against three for the minority (19%). According to 64% of the farmers, 50% of citizens of their respective square have latrines. Of 861 pigs identified, 20% were examined and 9.7% were carriers of cysts. Carcasses at slaughter percentage seizures ranged from 2.5% to 5% depending on the year; an average of about 4% over six years. The prevalence of infestations remained generally lower than those observed in some cities of northern Cameroon. Losses were estimated to average 5,31,900 FCFA / year. Knowledge and practice of screening techniques for this disease by producers would minimize economic losses, improvement of production quality and avoiding human contamination. Further investigation seems necessary to highlight the animal health status and quality of pork production in this area.
This study determined the seroprevalence of brucellosis in small ruminants in and around Bahir Dar, Ethiopia from 2008-2009. A total of 500 serum samples from sheep and goats were tested using the Rose Bengal plate test and complement fixation test. The overall prevalence of brucellosis was 1.2% by the Rose Bengal plate test and 0.4% by the complement fixation test. All positive samples by complement fixation test were from adult female goats. While the prevalence was low, the study concluded that brucellosis exists in the area and positive animals should be eliminated to control spread of the disease in small ruminants.
Ongoing disease control programmes in indiaBhoj Raj Singh
Animal Husbandry, Dairying and Fisheries sectors play an important role in the national economy and in the socio-economic development of the country. Livestock sector alone contributes 4.11% towards overall National GDP and 25.6% of total Agriculture GDP. The biggest impediment to growth of this sector, however, is the large-scale prevalence of diseases such as Foot and Mouth Disease (FMD), Hemorrhagic Septicemia (HS), Brucellosis, Black Quarter (BQ) in cattle, Enterotoxaemia, Peste des Petits Ruminants (PPR) & Sheep-Goat Pox in sheep and goats and Swine Fever in pigs, which drastically affect the productivity of animals. The presence of this disease not only deters the domestic economy but also foreign investment in the livestock sector. Although India have been free from disease like Rinderpest, Contagious Bovine Pleuropneumonia (CBPP), Bovine Spongiform Encephalopathy (BSE), presence of other economically important disease still threaten the very roots of livestock sector. This presentation describes various control programs that have been introduced by the Government of India, nationwide for controlling the infectious diseases of animals that have been or should be targeted for eradication or elimination, direct and indirect benefits from control programs, drawback issues and opportunities for the future.

FMD: Menace in India
Discusses problems of FMD Control in India like:
Lack of faith in farmers and veterinarians that FMD can be controlled with vaccination (due to repeated failure of vaccines in quality and vaccination failures resulting in FMD outbreaks).
Lack of infrastructure facilities for maintaining the cold chain and efficient transport to the vaccination site.
Lack of human resources for handling/ vaccinating livestock.
Needs for further researches on diagnosis (Pen-side), disinfection, vaccines and vaccination (affording at least a year immunity, quality vaccine etc.) and control strategies.
No-timely investigation or excessively delayed investigation of FMD outbreaks especially those occurring after vaccination.
Transparency in vaccine quality monitoring and vaccine purchases.
Fear in veterinarians for reporting FMD in their area of operation.
False statistics of the disease and vaccination.
No legal punitive action against suppliers of substandard FMD vaccines even after the supply of multiple substandard batches of vaccine.
This study examined the seroprevalence of brucellosis in small ruminants in Dire Dawa, Ethiopia. Blood samples were collected from 159 sheep and 265 goats and tested for Brucella antibodies. The overall seroprevalence was found to be 2.6%, with 1.9% in sheep and 3.0% in goats. There was no significant difference in prevalence between age groups, sexes, or species. Most respondents (66.7%) lacked awareness of brucellosis's zoonotic importance. Many flock owners (72.2%) drank raw milk and most (96.3%) handled fetal materials with bare hands, exposing them to Brucella infection
This document discusses brucellosis, a globally important zoonotic bacterial disease. It is caused by Brucella species and transmitted from animals to humans through contact or consumption of infected animal products like unpasteurized milk. In animals it causes reproductive issues like abortion. In humans it causes non-specific flu-like symptoms. Diagnosis involves isolating the bacteria or detecting antibodies. Treatment is difficult due to antibiotic resistance. It has significant public health and economic impacts especially in developing countries where control measures are not well implemented.
African swine fever epidemiology and control in smallholder pig systems: The ...ILRI
This document summarizes information about African swine fever (ASF) in smallholder pig systems in Africa, including:
1) ASF is caused by a virus that can survive for long periods outside a host. It has no vaccine and causes high mortality in pigs.
2) ASF transmission cycles involve domestic pigs, wild boar, soft ticks, and human activities. It is endemic in many African countries and has spread to Europe and Asia.
3) Controlling ASF is challenging due to multiple transmission cycles and lack of vaccines. Key control strategies include early detection, movement restrictions, culling, and improving biosecurity through practices like sanitation and restricting food waste access.

This document discusses avian influenza in Indonesia. It provides statistics on Indonesia's poultry population and production systems. Smallholder backyard farms account for 20% of production while commercial farms make up the remaining 80%. Avian influenza has been confirmed in 29 out of 33 Indonesian provinces. The government's national strategic plan aims to control avian influenza at its source in animals through culling, compensation, vaccines, and improved biosecurity. The plan also focuses on risk communication and strengthening human pandemic preparedness.
1) Researchers identified a new genotype (genotype XXIII) of the African swine fever virus (ASFV) in domestic pigs from Ethiopia. 2) Analysis of partial p72 and full p54 gene sequences showed this new genotype shares ancestors with genotypes IX and X found in Eastern Africa. 3) Analysis of the central variable region of the B602L gene also identified novel amino acid repeats not previously characterized.
Toxocara vitulorum infection has been reported to have a cosmopolitan distribution in whole of the tropical and subtropical regions of the world with a moderate, continental climate. Parasitic diseases of dairy animals are a universal problem and considered one of the major obstacles in health and production performance of animals. Retarded growth, poor production of milk, meat, poor quality of skin and hides are known harmful effects of parasitic infections in bovines. This study was aimed to determine prevalence of Toxocara vitulorum in Ambo area Sankalefaris peasant association in cattle of different Age and sex group. Across sectional study was conducted to investigate the prevalence of bovine ascariasis infection on 243 animals in Senkale Faris peasant association in Ambo district west Shewa zone. To achieve this; floatation techniques was employed. Based on this method about the overall prevalence was 243(63%) of which ages, and sex was a determinant factor Toxocara vitulorum. The known prevalence with age and sex category was <3 month,122(68%), 3-6 month, 70(61%), 6 month 30(12.3%) and 1 year 21(8.6%) p-value 0.000, from this we can say age of cattle has highly significant on enhancing the disease. In conclusion the result of the present study has revealed that there is high prevalence of ascariasis in calves, hence, appropriate treatment, control and owner’s awareness, should be implemented so that to increase the productivity of

Improved control of poultry movement and vaccination are needed to reduce virus spread and environmental load.
Brucellosis: Epidemiology and Control in indiaBhoj Raj Singh
This document summarizes information about bovine brucellosis, including its causative agent, transmission, clinical signs, epidemiology, diagnosis, and control programs in India. It discusses that B. abortus is the primary cause of bovine brucellosis. Seroprevalence studies in India show varied rates of infection across states, with some states reporting over 40% seropositivity. National control programs aim to reduce the disease impact through biannual screening, vaccination of female calves, and bull castration. However, effective control remains challenging due to issues like lack of disposal plans, limited vaccination coverage, and involvement of multiple animal hosts. Improved vaccines, diagnostics, and eradication strategies are still

Persistence of African swine fever outbreak in a farm in Kaduna, Nigeria.David Dazhia Lazarus
This document summarizes a study on the persistence of African swine fever outbreak in a farm in Kaduna State, Nigeria. The study found that five breeder houses on the farm were wiped out within a week of the outbreak. Testing of samples from the single surviving piglet confirmed the presence of African swine fever virus through serology and PCR analysis. The outbreak demonstrates that African swine fever continues to be a problem in Nigeria due to unregulated pig movements and lack of effective control strategies. Comprehensive surveillance, improved biosecurity, and government support are recommended to improve management of the disease.

Bovine Mastitis due to Coliform Bacteria, and Susceptibility to Antibiotics, ...Premier Publishers
This study was aimed at determining the prevalence of coliform bacteria in bovine milk in Plateau State of Nigeria and their antibiotic susceptibility patterns. A total of 640 milk samples were collected aseptically and 160 questionnaires from where data such as breed, age, parity, lactation stage, floor type, and husbandry system were analyzed. Cows without clinical mastitis were subjected to California Mastitis Test to determine the presence of subclinical mastitis. Bacteriological assays and antibiotic susceptibility tests were conducted according to standard guidelines. Subclinical mastitis with a prevalence of 63.8% was more prevalent in cows than clinical mastitis. Overall, the Friesian breed had the highest mastitis prevalence of 85.7% compared to White Fulani (which is indigenous in Nigeria). Cows aged within 2-4 years old had the least mastitis prevalence of 55.2%. Coliforms isolated from milk samples included E coli, K. pneumoniae, K. oxytoca, C. freundii, E. aerogenes, E. cloacae, and S. marcescens, with E coli having the highest prevalence of 44.8%. The most resistant antimicrobial agent was Streptomycin with 79% prevalence. The principle of One Health approach which targets the environment, animals and humans should be considered important. Good hygienic measures should be intensified among pastoralists.
Toxoplasmosis in Farm Animals in the United StatesHVCClibrary
This document provides an invited review on the prevalence of Toxoplasma gondii in farm animals in the United States. It discusses how T. gondii is one of the most common parasitic infections in humans and animals worldwide. Food animals like pigs, chickens, lambs and goats can become infected through environmental exposure to T. gondii oocysts, resulting in meat containing tissue cysts that can infect consumers if undercooked. Surveys have found T. gondii infection to be common in food animals in the US, especially pigs. The review examines prevalence studies in these various food animals and discusses the challenges in determining the relative contribution of food versus environmental transmission of T. gondii to humans
Emerging parasitic infections in goats in pastoral systems in kenyaAlexander Decker
This document summarizes a study on parasitic infections in goats in pastoral systems in Kenya. A total of 832 goats from 76 herds across 5 provinces were sampled to analyze tick infestation and strongyle egg counts. The overall mean tick count was 21 ticks per animal, with some districts having much higher counts. The overall strongyle egg count was 545 eggs per gram of feces. Both ticks and strongyle parasite infections were widely prevalent and at high levels. The study suggests these parasitic infections will become more economically important for pastoralists due to increasing pressure on grazing land and water sources. Further research is needed to understand disease transmission and impacts, and develop effective control strategies.
The purpose of the study was to know the conduct of pig farms, the state of cysticercosis and its consequences on the quality of production of pigs in N'Djamena, Chad. Three methods were used: (i) the transverse and retrospective survey for information related to the conduct and hygiene in 64 farms sampled in eight blocks belonging to three districts, (ii) the langueyage to observe cysts and (iii ) documentary investigation for total seizures in the slaughter house over six years. All farms had barns which were considered in good condition (66%). However, most of the farms (91%) did not practice permanent confinement. The majority (81%) accounted for two per day of food distributions to pigs against three for the minority (19%). According to 64% of the farmers, 50% of citizens of their respective square have latrines. Of 861 pigs identified, 20% were examined and 9.7% were carriers of cysts. Carcasses at slaughter percentage seizures ranged from 2.5% to 5% depending on the year; an average of about 4% over six years. The prevalence of infestations remained generally lower than those observed in some cities of northern Cameroon. Losses were estimated to average 5,31,900 FCFA / year. Knowledge and practice of screening techniques for this disease by producers would minimize economic losses, improvement of production quality and avoiding human contamination. Further investigation seems necessary to highlight the animal health status and quality of pork production in this area.

It concludes by discussing additional control measures used elsewhere like community sanitation programs, public education, pig vaccination and coordinated mass treatment of humans and pigs.
Distribution of cattle tick-borne haemoparasites in 54 Departments of Côte d’...Open Access Research Paper
The Rhipicephalus microplus tick is a major economic and veterinary concern on livestock production in tropical regions of the world. In Côte d’Ivoire, this invasive and proliferating tick has occupied almost the entire territory. To assess the prevalence of tick-borne haemoparasites in cattle following this invasion, a parasitological study was carried out in 179 farms in 54 departments. Blood and tick samples were collected from 895 cattle over one year of age, with 5 individuals per farm. Ten tick species were identified, of which Rhipicephalus microplus the most found. Microscopic analysis of blood smears identified 3 tick-borne haemoparasites: Anaplasma marginale, Anaplasma centrale and Babesia bovis, with prevalences between 4% and 24% according to departments. Only the Southern, Central, and Northern zones were infested with tick-borne haemoparasites of cattle. The highest prevalence of Babesia bovis (8%) was found in the Southern zone. Agboville’s department was the most infested by A. marginale (24%) and B. bovis (20%). Parasitological analyses revealed a low prevalence of tick-borne haemoparasites in Côte d’Ivoire. A molecular study should be conducted to confirm these results.
This study examined the seroprevalence of brucellosis in small ruminants in Dire Dawa, Ethiopia. Blood samples were collected from 159 sheep and 265 goats and tested for Brucella antibodies. The overall seroprevalence was found to be 2.6%, with 1.9% in sheep and 3.0% in goats. There was no significant difference in prevalence between age groups, sexes, or species. Most respondents (66.7%) lacked awareness of brucellosis's zoonotic importance.

Characteristics of village chicken production in farming system in Côte d’Ivo...Agriculture Journal IJOEAR
Abstract— A study on the local chicken production parameters has been undertaken in the area of Korhogo. The work was conducted by a survey focused on 110 small farms from 20 villages (Koulélékaha, Natyo- Kobadara, Bafimé, Paroginékaha, Latakaha, Lénékaha, Lérikaha, Dyègbè, Pokaha, Torgokaha, Dokaha, Karakoro, Tyoronyaradougou, Nanbadyélékaha, Konborodougou, Dobyankaha, Lonakaha, Nalougovogo, Nalolokahaand Nanvikaha)in the department of Korhogo. The herd of the poultry farms varied from 10 to 105 chickens. The work shown that traditional poultry farming is practiced in majority by women and young with respective distributions of 60 % and 62.27 %. In 82 % of cases, breeding products are both for home consumption and marketing. Only 20 % of that product are solely for sale and marketing. The breeding system of that farm is extensive with a dietary and sanitary behavior which does not comply with the art standard. The housing of these animals are precarious henhouses which do not fit norms and good hygiene practice to guarantee the well-being of those birds. Three (3) types of chickens were defined on the basis of the tradition of the Sénoufo(people of the north of the Côte d’Ivoire) considerations. The age for chickens to start laying varied from 6 to 8 months for39 ± 4 eggs in 3 ± 1.10 laying per year. The eggs per laying were 9.75 ± 4 eggs for an average weight of 35 ± 3.48 g. The average incubation duration was 21 ± 2 days with a hatching rate varying between 50 % and 90 %. The adulthood traditional chickens' weight in that farm varied from 1 to 1.5 kg.

Bovine mastitis has a negative impact through economic losses in the dairy sector across the globe. A cross sectional study was carried out from September 2015 to July 2016 to determine the prevalence of bovine mastitis, associated risk factors and isolation of major causative bacteria in lactating dairy cows in selected districts of central highland of Ethiopia. A total of 304 lactating cows selected randomly from five districts were screened by California Mastitis Test (CMT) for subclinical mastitis. Based on CMT result and clinical examination, over all prevalence of mastitis at cow level was 70.62% (214/304).
Two hundred fourteen milk samples collected from CMT positive cows were cultured for isolation of major causative bacteria. From 214 milk samples,187 were culture positive and the most prevalent isolates were Staphylococcus aureus 42.25% (79/187) followed by Streptococcus agalactiae 14.43%
(27/187). Other bacterial isolates were included Coagulase Negative Staphylococcus species 12.83% (24/187), Streptococcus dysgalactiae 5.88% (11/187), Escherichia coli 13.38% (25/187) and Entrococcus feacalis 11.23% (21/187) were also isolated. Moreover, age, parity number, visible teat abnormalities,husbandry practice, barn fl oor status and milking hygiene were considered as risk factors for the occurrence of bovine mastitis and they were found significantly associated with the occurrence of mastitis (p < 0.05). The findings of this study warrants the need for strategic approach including dairy extension that focus on enhancing dairy farmers’ awareness and practice of hygienic milking, regular screening for subclinical mastitis, dry cow therapy and culling of chronically infected cows.
Production and marketing behaviour of hadiya pastoralists southern ethiopiaAlexander Decker
This document summarizes a study on the cattle production system of Hadiya pastoralists in southern Ethiopia. Some key findings:
1) Hadiya pastoralists keep large herds of cattle, not just as an economic asset but due to their cultural obligation, with herd sizes and cattle ownership associated with social status.
2) Households engaged in selling cattle (the "selling position") tended to be older, with more wives and experience, and owned significantly more cattle than other households.
3) While cattle are the most important livestock, goats, donkeys and poultry are also raised, but environmental factors prevent rearing of camels and sheep.

Community Breeding Practice and the Challenges in Dairy Cattle Management in ...Agriculture Journal IJOEAR
Abstract— Dairy product is an important feed supplementation. However, rearing dairy cattle is became a challenge especially at smallholder level due to lack of indigenous dairy cattle breeds. As a result, the country has established cross breeding program since 1990`s. Nevertheless, it is not uniform and does not consider smallholder farmers. Therefore, this research initiated to identify the breeding practice and the main challenges of smallholder farmers in rearing dairy cattle. For this purpose, first systematic field survey was conducted to generate preliminary information and breed judgment. Then two study areas were selected purposively based on milk production potential and dairy breed characteristics. Two focus group discussions per study area were conducted. Then, randomly 200 respondents per study area were selected. Finally, individual interview and field observation were employed to generate the needed data. Even though there is no established breeding scheme, the smallholder farmers practiced breed improvement by either cross breeding or straight breeding. They implemented Cross breeding to improve milk productivity using 50-100% exotic blood sire/semen. Pure exotic semens were preferred for AI (Artificial insemination). The smallholder framers do not select indigenous caw for cross breeding practice. However, they selected indigenous caw/heifer for replacement based on pedigree history, body stature, and udder vein. Regarding mating system, more than 50% of the respondent exercise control-mating system in their herd. Mostly this was done by pertaining the sire and dam together for a single day. In addition to this partiality in preference of sire, less productive individual cattle culled from the herd by castration, sell and slaughtering. The management system, early castration and lack of accurate estrus detection were the major challenges in dairy cattle development. As the result of this survey in the two study areas, indiscriminate cross breeding without consideration of the production system, body size and blood levels were predominant. Therefore, successive training for smallholder farmers on breeding system is highly recommended.

This document discusses Gandhi's concept of trusteeship as an alternative economic system. It summarizes that Gandhi did not distinguish between economics and ethics, and based trusteeship on religious ideas like non-possession and truth as well as Western ideas like stewardship. Trusteeship aimed to persuade wealthy property owners to hold wealth in trust for the benefit of society rather than personal gain. It was meant as a non-violent alternative to capitalism and communism that eliminated class conflict through cooperation and trust between rich and poor. The document provides background on the philosophical and religious influences on Gandhi's views before explaining the key aspects of his theory of trusteeship.
Impacts of a New Spatial Variable on a Black Hole Metric SolutionIJSRED
This document discusses the impacts of introducing a new spatial variable in black hole metrics. It begins by summarizing Einstein and Rosen's 1935 paper which introduced a variable ρ = r - 2M in the Schwarzschild metric to remove the singularity. The document then introduces a similar new variable p = r - 2√M and analyzes how this impacts the Schwarzschild metric. Specifically, it notes that this new variable allows for negative radii values and multiple asymptotic regions beyond just two, introducing concepts of probability and imaginary spatial coordinates. Overall, the document explores how different mathematical variables can impact theoretical physics concepts like wormholes.

The goal is to improve upon traditional crop selection methods and help increase farmers' incomes.
Functions of Forensic Engineering Investigator in IndiaIJSRED
Forensic engineering involves applying engineering principles and methodologies to answer legal questions, especially regarding accidents and failures. A forensic engineer investigates failures through failure analysis and root cause analysis to determine how and why something failed. The engineer must be familiar with relevant codes and standards, understand eyewitness testimony, apply the scientific method to reconstruct events, and report findings clearly to assist courts. A forensic engineering investigation follows the scientific method to methodically analyze evidence and test hypotheses to determine the cause and circumstances of a failure or accident.
An improved modulation technique suitable for a three level flying capacitor ...IJECEIAES
This research paper introduces an innovative modulation technique for controlling a 3-level flying capacitor multilevel inverter (FCMLI), aiming to streamline the modulation process in contrast to conventional methods. The proposed
simplified modulation technique paves the way for more straightforward and
efficient control of multilevel inverters, enabling their widespread adoption and
integration into modern power electronic systems. Through the amalgamation of
sinusoidal pulse width modulation (SPWM) with a high-frequency square wave
pulse, this controlling technique attains energy equilibrium across the coupling
capacitor. The modulation scheme incorporates a simplified switching pattern
and a decreased count of voltage references, thereby simplifying the control
algorithm.

Advanced control scheme of doubly fed induction generator for wind turbine us...IJECEIAES
This paper describes a speed control device for generating electrical energy on an electricity network based on the doubly fed induction generator (DFIG) used for wind power conversion systems. At first, a double-fed induction generator model was constructed. A control law is formulated to govern the flow of energy between the stator of a DFIG and the energy network using three types of controllers: proportional integral (PI), sliding mode controller (SMC) and second order sliding mode controller (SOSMC). Their different results in terms of power reference tracking, reaction to unexpected speed fluctuations, sensitivity to perturbations, and resilience against machine parameter alterations are compared. MATLAB/Simulink was used to conduct the simulations for the preceding study. Multiple simulations have shown very satisfying results, and the investigations demonstrate the efficacy and power-enhancing capabilities of the suggested control system.
