Intensive swine production increases the exposure risk of piglets to immunological stress that disrupts hepatic functionality, leading to inferior disease resistance and compromised growth performance. Therefore, it is imperative to seek appropriate nutrients with protective potential to alleviate liver injury of young piglets under the conditions of immunological stress.

Maternal nutrient restriction during the last trimester of pregnancy impairs the fetal development, increases morbidity and mortality, and reduces its performance in adult life. Animals with compromised pregnancies exhibit a reduction in uterine blood flow thereby limiting the nutrients available for the fetus to grow and develop.

To reduce cost and also utilize locally produced ingredients, pig diets nowadays can include a large proportion of fiber-rich ingredients. Exogenous enzymes can be added to diets to improve their digestibility and limit negative effects of fiber.

Microbial phytase increases the digestibility by pigs of phytate-bound P in feed ingredients of plant origin, but digestible P can also be increased in diets by the addition of feed phosphates due to their high digestibility of P and lack of phytate. However, it is possible that the phytate from plant ingredients complexes with P from feed phosphates, resulting in a lower digestibility of P, but research to address this possibility has not been reported.

Ducks use bathing water for wet preening and feather maintenance. Commercially, it is challenging to provide clean bathing water without compromising litter quality and duck health.

Fat is involved in the synthesis of new fatty acids (FAs), FA circulation, and lipid metabolism. Various genetic studies have been conducted on porcine fat but understanding the growth and specific adipose tissue is insufficient. The purpose of this study is to investigate the epigenetic difference in abdominal fat according to the growth of porcine.

Methane production from cattle digestion results in the loss of 6% to 10% of gross energy intake in cattle and globally is the single most significant source of anthropogenic methane (CH4) emissions. The purpose of this study was to analyze greenhouse gas traits recorded in a commercial feedlot unit to gain an understanding into the relationships between greenhouse gas traits and production traits of economic importance.

Prior biological information can be helpful in the genomic prediction of the traits. Previous multi-omics studies by our group identified genes relevant to puberty and fertility in Brahman cattle, a beef breed in northern Australia. We used this biological information in the genomic prediction of three heifer fertility traits, measured in another beef cattle breed: Tropical Composites.

In 2021, US$50 billion was spent on pet food and pet treats in the United States alone. Pet diets are largely sourced from animal proteins; however, the sustainability of these diets remains a major concern. Microbial proteins from microorganisms such as yeasts offer a sustainable protein alternative.

The feature infographic examines the ways that neonatal mammals acquire first immunity. The review paper, “Implications of placentation type on species-specific colostrum properties in mammals, “looks at how different species confer passive immunity to their young.

During evolution of mammalians, intrinsic strategies and components of maternal care during the transition from pregnancy to lactation have evolved into a broad variety in gestation length, number, size, and maturation stage of the offspring at parturition, and colostrum and milk composition.

Broilers are susceptible to physiological stress under the environment of faster growth that may cause growth retardation, and this problem has inspired the research in alternative managements and dietary strategies to control the incidence and severity. Due to the consumer preference for natural products, the application of polyphenol compound has been increasing in appeal.

The objective of this study was to evaluate the effectiveness, economic benefit, and animal performance of oxfendazole, eprinomectin, and a combination of both anthelmintics during a 42-day preconditioning phase in naturally infected, recently weaned calves at four different research locations.

In dairy cows, the transition from late pregnancy to the early postpartum (PP) period and the onset of lactation is characterized by vast changes in metabolism and immune function, thus the concept of immunometabolism is particularly relevant at this stage of the dairy cows’ life.

The United States Department of Agriculture’s (USDA’s) Farm Service Agency (FSA) has announced that dairy producers can now enroll for 2023 coverage through the Dairy Margin Coverage (DMC) Program. The DMC safety net program from USDA helps producers manage changes in milk and feed prices.

The Food and Drug Administration (FDA) has announced that it has submitted the FDA Food Safety Modernization Act (FSMA) Final Rule: Requirements for Additional Traceability Records for Certain Foods. The rule is proposing to establish additional traceability recordkeeping requirements for persons that manufacture, process, pack, or hold foods the FDA has designated for inclusion on the Food Traceability List.

The United States Department of Agriculture (USDA) has announced $800 million in debt relief to distressed USDA farm loan borrowers. The loans will assist approximately 115,000 producers who cannot obtain sufficient commercial credit through direct and guaranteed farm loans.

The United States Department of Labor has published a final rule to amend the H-2A visa program. The final rule, Temporary Agricultural Employment of H-2A Nonimmigrants in the United States, is effective as of November 14, 2022.

The National Institutes of Health (NIH) has published a new policy resource page, Animals in NIH Research. The webpage provides details on how, why, and when NIH uses animals in biomedical research and the associated benefits.

President Biden has signed the National Security Memorandum on Strengthening the Security and Resilience of United States Food and Agriculture. The memorandum builds on the Biden Administration’s ongoing work to ensure Americans have access to safe, affordable food, that US producers can get their goods to market, and that the US food and agricultural system is better prepared for threats that may harm the health of crops and livestock and cause shocks to the cost or availability of food.
