Kernel processing of corn silage has yielded inconsistent results on diet digestibility and growth performance in beef cattle. These are likely a function of a variety of factors such as differing dry matter concentration of corn silage at harvest, diet inclusion levels, and length of cut.

Predictions for the Midwest U.S. indicate that both winter and spring temperatures and precipitation will increase. These climatic changes could result in muddier conditions during winter and spring in the Midwest. It has previously been demonstrated that a muddy environment increases the net energy requirements of mature cow’s by approximately 3.9 Mcal/d.

The selection of Aleutian disease-resistant individuals based on Aleutian disease (AD) tests is seen as a potential method to control AD effectively. However, the knowledge regarding the genetic background of AD tests is limited.

Sustainable ingredients are of increasing demand within the pet food industry. Corn-fermented protein (CFP) could provide a sustainable protein source for pet food.

In tandem with the fast expansion of the pet-economy industry, the present aging research has been noticing the function of probiotics in extending the healthy lifetime of domestic animals. In this study, collaborating with understanding the characteristics of gut microbiome from canine feces by multiomics approaches including culturomics, metagenomics, and transcriptomics, we isolate and identify commensal lactic acid bacteria (LAB) as novel potential probiotics for the use of antiaging using Caenorhabditis elegans surrogate animal model and multiomics analysis.

Very few studies have been conducted to determine the differences in environmental impacts based on the diet composition of growing-finishing swine feeding programs across major pork production regions in the United States. Therefore, the objective of this study was to determine and compare greenhouse gas (GHG) emissions, water consumption, land use, as well as nitrogen (N), phosphorus (P), and carbon (C) balance of five diet formulation strategies and feeding programs for growing-finishing pigs (25–130 kg body weight) in the three spatially explicit U.S. pork production regions.

The purpose of this study is to optimize the isolation and culture method for muscle stem cells, called satellite cells, in the breast muscle of meat-type chicken (Broiler). Satellite cells play pivotal roles in muscle development, growth, and muscle regeneration.

Cow–calf operations in the tropics and sub-tropics have benefited from the environmental adaptation provided by Bos indicus genetics. However, reproductive performance has been a cause of concern, although poorly quantified. This study characterized how much the B. indicus genetics in crossbred cows influence herd reproduction.

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.
