    Interpretive Summary: Effects of weight loss and feeding specially formulated diets on the body composition, blood metabolite profiles, voluntary physical activity, and fecal metabolites and microbiota of obese dogs


    In this study, we aimed to determine the effects of restricted feeding of specially formulated foods on weight loss, body composition, voluntary physical activity, serum hormones and oxidative stress markers, and fecal metabolites and microbiota populations of obese dogs. A control (OR) food was fed during a 4-wk baseline to identify intake needed to maintain the body weight (BW).

    Interpretive Summary: Short communication: diversity of endogenous avian leukosis virus subgroup E elements in 11 chicken breeds


    Avian leukemia virus subgroup E (ALVE) is an endogenous retrovirus, which is extensively integrated with the chicken genome, and has some effects on chicken production traits and appearance. Most of the current studies on ALVE insertion sites were conducted in standard breeds.

    Interpretive Summary: Effects of lasalocid, narasin, or virginiamycin supplementation on rumen parameters and performance of beef cattle fed forage-based diet


    Feed additives are nutritional tools that benefit dietary digestibility and nutrient utilization, alter ruminal fermentation routes, and improve cattle growth and efficiency, thus increasing productivity and profitability in beef cattle systems. Nonetheless, most of the current research focuses on supplementing feed additives in high-concentrate diets.

    Interpretive Summary: Level of feeding and stage of maturity affects diet digestibility and protein and fat deposition in cross-bred lambs


    Understanding animal responses to changes in nutrition will assist to create more efficient red meat production systems. Complex interactions exist due to the quality, physical characteristics and level of feeding of the diet, and the nutritional history of the animal. The resultant changes to body composition and the partitioning of energy to tissues has important implications for producers.

    Interpretive Summary: Effects of adding ruminal propionate on dry matter intake and glucose metabolism in steers fed a finishing ration


    Propionate metabolism by the liver is thought to be a key regulator of appetite and feed intake of animals, including cattle. Previous research has shown that providing propionate to the rumen of cattle decreases feed intake.

    Interpretive Summary: Influence of fiber-rich coproducts on nutrient and energy digestibility and utilization in sows


    Coproducts from the food and agricultural industries have the potential to partly substitute grain in diets for empty nonlactating sows. Many coproducts are high in fiber and with diverse fiber composition. Some being easily fermented, while others are more resistant to fermentation giving rise to a large variation in the total tract digestibility and utilization of nutrients and energy.

    Interpretive Summary: Effects of dietary crude protein level and sodium butyrate protected by medium-chain fatty acid salts on performance and gut health in weaned piglets


    Reducing dietary levels of crude protein (CP) and the use of feed-additives such as sodium butyrate protected by medium-chain fatty acid salts are currently under investigation as nutritional strategies with beneficial effects on the intestinal barrier, and consequently on the health of weaned piglets.

    Interpretive Summary: One-carbon metabolism and related pathways in ruminal and small intestinal epithelium of lactating dairy cows


    The gastrointestinal tract serves a number of essential functions in the animal and exposure to physiological and environmental stressors can lead to disruption of its barrier function and compromise nutrient absorption. In nonruminants, mechanisms to cope with pro-oxidant and pro-inflammatory stressors are essential for maintaining gut function.

    Interpretive Summary: Lipid metabolism mRNA expression and cellularity of intramuscular adipocytes within the Longissimus muscle of Angus- and Wagyu-sired cattle fed for a similar days on feed or body weight endpoint


    This study investigates intramuscular (IM) adipocyte development in the Longissimus muscle (LM) between Wagyu- and Angus-sired steers compared at a similar age and days on feed (D) or similar body weight (B) endpoint by measuring IM adipocyte cell area and lipid metabolism mRNA expression. Angus-sired steers (AN) were compared with steers from two different Wagyu sires (WA), selected for either growth (G) or marbling (M), to be compared at a similar days on feed (DOF; WA-GD, and WA-MD) in Exp. 1 or body weight (BW; WA-GB, and WA-MB) in Exp. 2.

    Interpretive Summary: Effect of weaning strategy and backgrounding management on growth performance, carcass characteristics, and mRNA expression in the longissimus muscle of beef steers


    The intramuscular fat depot, also called marbling, is a vital component of beef quality. This study aimed to investigate the effect of the weaning strategy (early vs. normal) and the subsequent backgrounding management on marbling deposition of beef carcasses.

    Interpretive Summary: Galyean appreciation club review: a holistic perspective of the societal relevance of beef production and its impacts on climate change


    This article aims to provide data-driven information about the relevance of the U.S. beef cattle herd to our society and its greenhouse gas (GHG) contribution to climate change. The Environmental Protection Agency reported that U.S. beef cattle emitted 22.6% of the total agricultural emissions, representing about 2.2% of the total anthropogenic emissions of carbon dioxide equivalent (CO2e).

    Interpretive Summary: Enterococcus faecium from chicken feces improves chicken immune response and alleviates Salmonella infections: a pilot study


    Infectious bacterial contamination in broiler production is a food safety concern and can be transmitted to humans via contaminated meat and derived products. Minimizing bacterial infections using beneficial bacteria called probiotics can reduce the emergence of antibiotic resistance in the livestock industry.

    ADD SOY Act introduced


    A new bipartisan bill was introduced by Congressman Troy A. Carter, Sr. (D-LA.) and Congresswoman Nancy Mace (R-SC) that would require schools to provide fluid milk substitutes upon request of a student or parent/guardian. The Addressing Digestive Distress in Stomachs of Our Youth (ADD SOY) Act would make soy milk available to children in schools who need an alternative to cow’s milk.
