Although in vitro data with mixed ruminal fluid demonstrated positive effects of postbiotics from lactobacilli on measures of fermentation and microbial profiles, there is a paucity of in vivo data with lactating ruminants. We evaluated the effects of incorporating a postbiotic yeast fermentation product in diets of lactating goats on energy partitioning, carbon and nitrogen balance, and performance.

The inclusion level of wheat in poultry feeds is limited by nonstarch polysaccharides (NSP). Feeding NSP will increase the intestinal viscosity and residence time of the digesta, reduce nutrient digestion, and absorption of nutrients by birds, thereby damaging the intestinal function and growth performance.

Gilt development feeding programs are important to ensure that the female grows at an appropriate rate, without becoming overconditioned or developing locomotion issues. Moreover, between 90 d of age and puberty is the first phase of rapid mammary development, which is necessary to support milk production after farrowing and which can be negatively impacted by reduced energy and protein intakes.

Male sexual behavior is a key factor in reproduction, especially in seasonal breeders such as sheep. The identification of differentially expressed genes (DEGs) in brain regions involved in male reproduction and sexual behavior between rams with different sexual activity by RNA high-throughput sequencing can provide useful information to the sheep meat industry.

Over the past 115 years, the American Society of Animal Science (ASAS) has evolved into a multi-faceted organization, including establishing the ASAS Foundation 25 years ago as the philanthropic branch of ASAS. The Foundation enhances, advances, and supports ASAS’ mission and initiatives.

This experiment evaluated the effects of dietary inclusion of hempseed cake or dried corn distillers grains plus solubles on ruminal fermentation parameters, organic matter (OM) intake, total tract nutrient digestion, and nitrogen (N) balance in steers fed finishing diets.

Stress from weaning, feed restriction, transportation, and gastrointestinal acidosis can cause inflammation and intestinal damage, resulting in decreased absorptive capacity and immune defense capability. Gastrointestinal inflammation has a significant catabolic cost and causes nutritional resources to be directed away from anabolic processes.

Greenhouse gas emissions are a major concern in the beef industry. This study examined the effects of supplementation with ruminal probiotics consisting of three native ruminal microbes (NRM) for their influence on methane reduction and growth performance of beef cattle.

The objective of this review is to summarize the current knowledge on the effect of protein and energy restriction during the last third of gestation to beef cows on growth performance of offspring, focusing principally on Bos taurus cows.

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.
