The primary objective of the current study was to create a classification system and management of available ingredients for sheep and cow farmers. Additionally, the study aimed to investigate the techniques employed in production and the types of feed ingredients utilized, specifically focusing on those accessible within the local context in Benin.\u0000Materials and methods: An open-ended questionnaire was used for this study, followed by in-person interviews. A cross-sectional survey was carried out from March to April 2023, in three poles of development agriculture (PDA), including PDA2, PDA4, and PDA5, where the government projected to develop ruminant breeding. Data were collected from 450 sheep, and cow breeders selected based on the number of their animals and the breeding experience in the three PDAs. The breeders' socio-demographic characteristics, the feed supplementation practice, and the available feed resources were recorded.\u0000Results: The survey revealed that sheep and cows were bred more by men (54.67%), married people (78.57%), and illiterate individuals (64.74%). The average age of the breeders was 45.66 years. Only 9.83% received training in animal breeding, and their main activity was cropping production. Regardless of the PDA, commercial feeds were well known but rarely used by breeders due to their high cost. Some breeders used commercial feeds only in the dry season. The feed supplements included lick stones, multi-nutritional blocks, and pelleted and floury feeds. The most widely used ingredients were agricultural by-products (cereals and legumes) and agro-industrial by-products (maize bran, cottonseed cake, and palm kernel cake).\u0000Conclusion: The current study's findings have indicated a wide range of feed resources, such as agricultural and agro-industrial by-products in Benin, that can be exploited to produce efficient local feed supplements.","PeriodicalId":318133,"journal":{"name":"Farm Animal Health and Nutrition","volume":"114 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-08-29","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"124797401","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The current study investigated the influences of supplementing Nigella sativa (NS) seeds to an Aflatoxin-contaminated diet on rumen parameters, digestibility, and nitrogen balance of male Nubian goats.\u0000Materials and methods: A total number of 20 healthy male Nubian goat kids aged 8-9 months and an average weight of 11 ± 0.5 kg were randomly assigned to 5 equal groups. The control group (T1) received a basal diet. The second treatment group (T2) received the same diet contaminated with 150 ppb Aflatoxin and other treatments received an aflatoxin-contaminated diet supplemented with different levels of crushed NS seeds including 2% (T3), 4% (T4), and 6% (T5) of the total dry matter. Through using naturally infected groundnut cake, Aflatoxin was mixed with other ingredients of ration in different proportions to formulate treated diets. High-performance liquid chromatography was used to determine Aflatoxin concentration. Rumen liquor samples were collected after 40 days feeding period to evaluate rumen pH, volatile fatty acids (VFAs), ammonia nitrogen (NH3-N), rumen electrolytes, and protozoa count.\u0000Results:  Rumen pH, ammonia nitrogen, ruminal sodium, and potassium were not significantly affected by the treatment groups. Rumen volatile fatty acids, protozoa count, nutrient digestibility, and nitrogen retention were significantly reduced by an Aflatoxin-contaminated diet (T2) compared to other groups. Supplementation of NS seeds to an Aflatoxin-contaminated diet caused a significant increase in VFAs, decreased protozoa count, and improved digestibility and nitrogen retention in all treated groups compared to T2 and T1 groups.\u0000Conclusion: Supplementing NS seeds to an Aflatoxin-contaminated diet positively affected rumen ecology and improved digestibility and nitrogen retention. The study recommended supplementing 6% of NS seeds to goat diets can reduce the negative effects of Aflatoxin in the diet.","PeriodicalId":318133,"journal":{"name":"Farm Animal Health and Nutrition","volume":"76 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-08-29","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"127214673","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This study evaluated the productive and reproductive performance, feed resources, feed management, and major constraints of three breeds of cattle (White Fulani, Sokoto Gudali, and Red Bororo) production under an extensive system in Northern Nigeria.\u0000Materials and methods: A structured questionnaire survey and group discussion were used for collecting data. 60 farmers with 30 years of experience in cattle farming were selected to administer the questionnaire. Each breed (White Fulani, Sokoto Gudali, and Red Bororo) was grown by 20 farmers.\u0000Results: The results indicated that 70% of the farmers agreed with the first service at the age of 2.3-3 years in the three breeds. The first calving at the age of 3.3-4 years was 40% for White Fulani farmers, while 80% for Sokoto Gudali and Red Bororo farmers respectively. The calving interval in the range of 1-2 years was adequately observed in all three breeds. The age of 13-15 years was reported as the female reproductive period in this study. The total number of calves produced per cow's lifetime in the present study was estimated at 8-11 for White Fulani and Sokoto Gudali, and 4-7 for Red Bororo. Feed resources and management of three breeds of cattle under extensive management indicated that natural pasture was the most common source of feed for cattle in the rainy season. Besides, natural pasture, tree leaves, and shrubs were used as cattle feed in the dry season. The main cattle production constraints reported by the farmers included feed and water in the study area.

The COVID-19 pandemic, which rapidly spread to 187 countries, has caused significant economic disruption in various industries, including the dairy industry. The dairy industry has been affected by supply chain disruptions, consumer behavior changes, and global demand shifts due to the pandemic. The present review aims to evaluate the impact of the COVID-19 pandemic, mainly from the dairy farm level, and propose strategies for mitigating the effects of future global crisis events. The dairy industry, a major source of income for many dairy herds, was significantly impacted by the COVID-19 pandemic. The consumption patterns of milk and dairy products underwent substantial alterations, leading to decreased profitability of dairy farms due to disruptions in the supply chain, increased transportation costs resulting from transportation restrictions, and a shift in consumer purchasing behavior. These factors collectively resulted in reduced revenue from selling milk and dairy products. Heifer replacement considerations also impacted the economic viability of dairy farms. The pandemic caused a shortage of meat (beef, pork, poultry) and a surplus of milk. In addition to the abovementioned factors, the COVID-19 pandemic also impacted other economic indicators, such as gross returns from the sale of culled dairy animals and dairy feed costs. These impacts further amplified the financial challenges faced by the dairy industry and dairy farmers, underscoring the need for robust mitigation strategies and resilient policies to minimize the economic impact of pandemics and other crises. In conclusion, the COVID-19 pandemic has profoundly impacted the dairy industry, affecting supply chains and international commerce. Governments are encouraged to implement measures to mitigate the impact of future pandemics on the dairy sector. The authors of this review propose several recommendations for dairy farmers and veterinarians to increase their resilience in the face of future outbreaks. These recommendations include sourcing feed from reliable local farms, acquiring internet connectivity equipment to facilitate communication during travel restrictions, maintaining a sufficient supply of personal protective equipment, incorporating mechanization in farm operations, stockpiling essential veterinary medications and vaccines, and training technicians to perform veterinary procedures in emergencies when veterinary services are unavailable.","PeriodicalId":318133,"journal":{"name":"Farm Animal Health and Nutrition","volume":"54 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-03-25","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"129878101","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This feeding trial was carried out to evaluate the responses of growing boarfed sundried cassava peel meal (CPM)-based diet supplemented with the enzyme. Materials and methods: Thirty-two growing boars (Large white x Landrace), eleven weeks old with an average weight of 25.00 ± 0.30 kg, were allocated randomly to dietary treatments. A basal diet was compounded containing 48% sundried CPM. The dietary treatments were T1 (control) supplemented with 0.0g/100g, and other treatments, including T2, T3, and T4, received 0.5g/100kg, 1.5g/100g, and 2.0g/100g levels of Quadraxyme® supplementation, respectively. Quadraxyme® is a product of Quadragen Veterinary Health Private Limited. Quadraxyme® contains amylase, cellulase, xylanase, pectinase, lipase, arabinose, α-galactosidase, and β -glucosidase. Results: This study showed significant differences in average feed intakes and daily weight gains across the dietary treatments. Pigs in the T4 group had the highest weight gain, followed by those in T2 and T3 groups, while the minor weight gain was in the diet with no enzyme supplementation. The dietary treatments significantly influenced hematological parameters in almost all the studied indices. The mean corpuscular hemoglobin concentration (MCHC) values of pigs fed the T1 diet recorded significantly higher MCHC and a reduction in concentrations of packed cell volume, red blood cell counts, and a slight increase in mean corpuscular volume concentration. The dietary treatments did not affect the total blood protein and albumin levels of the growing pigs enrolled in this investigation. The result showed that the levels of enzyme supplementation to the SDCPM-based diet did not significantly influence the electrolytes of the growing boars. The PO42- increased in enzyme-supplemented diets, and group T4 supplemented with 0.20g/100kg of the enzyme recorded the highest PO42- value (6.79mg/100ml) among the other groups.

The purpose of this paper was to provide an overview of recent research on the host's innate immune system, barriers, and cells that respond to parasitic nematodes. This study investigated the nematode-associated molecular patterns that may recognize by host. Given the innate defense is more than just a static barrier against pathogen infections. It can actively contribute as a director of the adaptive immune response, which is ultimately responsible for the rejection of invasions. The role of innate defense against pathogen infections is located in zone of researcher concentration. Some nematode parasites can actively move through tissues, they pose a challenge to the innate immune system. Furthermore, their cuticular surface, which varies with each molting, cannot be phagocytosed. The nematode's thin, carbohydrate-rich surface layer, as well as the chemicals produced by this layer, cause the first contact with the host's innate immune system.
