    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.

    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: An investigation of the effect of folic acid and its delivery routes on broiler chickens’ hatch and growth performance, blood biochemistry, anti-oxidant status, and intestinal morphology


    Folic acid (FA) is an essential vitamin with anti-oxidant and growth-promoting properties. Notwithstanding, studies have shown that, like other bioactive substances, its efficacy can be affected by dosage and delivery routes. However, the in ovo delivery of bioactive substances directly to the developing embryo continues to show promising results in poultry production.

    Interpretive Summary: Metabolome of purulent materials of liver abscesses from crossbred cattle and Holstein steers fed finishing diets with or without in-feed tylosin


    Liver abscesses in feedlot cattle, a consequence of feeding a diet of high-grain and low-roughage, are a mixed bacterial infection with Fusobacterium necrophorum, a ruminal bacterium as the primary causative agent. Cattle with liver abscesses do not exhibit clinical signs and the abscesses are detected only at slaughter.

    Interpretive Summary: Strategies for accommodating gene-edited sires and their descendants in genetic evaluations


    Coupling gene editing, a technology with the potential to make specific changes to DNA sequence (e.g., quantitative trait nucleotide, QTN), with genomic selection can generate faster genetic gain in economically important traits. However, gene editing would impact the genetic relationship among individuals and, consequently, genetic evaluations. The objectives of this study were to understand how gene editing impacts genetic prediction and develop strategies to mitigate potential errors in estimated breeding values (EBV).
