    Interpretive Summary: Effects of bacterial direct-fed microbial combinations on beef cattle growth performance, feeding behavior, nutrient digestibility, ruminal morphology, and carcass characteristics


    Direct-fed microbials (DFM) are naturally occurring microorganisms that alter cattle ruminal fermentation and intestinal function and have been shown to improve growth performance and nutrient digestibility of cattle. The use of DFM in animal feed has continuously increased in feedlots as an alternative to traditional antibiotic additives, which have gained negative public perception and additional regulatory scrutiny.

    Interpretive Summary: The effects of torula yeast as a protein source on apparent total tract digestibility, inflammatory markers, and fecal microbiota dysbiosis index in Labrador Retrievers with chronically poor stool quality


    Pet and human populations continue to grow and compete for nutritious, sustainable protein sources. The incorporation of alternative proteins like torula yeast can provide a solution to this problem. Torula yeast also may have additional health benefits like reducing gut inflammation.

    Interpretive Summary: Supplementing vitamins and minerals to beef heifers during gestation: impacts on mineral status in the dam and offspring, and growth and physiological responses of female offspring from birth to puberty


    Great variation exists in management decisions to offer a vitamin and mineral supplement to cow–calf herds in the Northern Great Plains. Decisions to supplement (or not) vitamins/minerals during critical periods of fetal development may have lasting postnatal impacts on the offspring; however, there is a lack of reports focusing on the long-term offspring outcomes.

    Interpretive Summary: Impact of maternal live yeast supplementation to sows on intestinal inflammatory cytokine expression and tight junction proteins in suckling and weanling piglets


    Increasing evidence supports the benefits of improving sow nutrition during gestation and lactation to promote gastrointestinal development and overall health of piglets. The objective of this research was to investigate the effects of maternal live yeast (LY) supplementation to sows during late gestation and lactation periods on the intestinal health of suckling and weaned piglets.

    Interpretive Summary: Effect of Saccharomyces cerevisiae Postbiotics and Essential Oil on Growth Performance and Intestinal Health of Weanling Pigs During K88 ETEC Infection


    Weanling pigs are vulnerable to a variety of stressors and pathogen infections. Enterotoxigenic Escherichia coli (ETEC) is one of the leading causes of diarrhea and growth retardation in weanling pigs.

    Interpretive Summary: Effects of dietary supplementation with 3-nitrooxypropanol on enteric methane production, rumen fermentation, and performance in young growing beef cattle offered a 50:50 forage:concentrate diet


    Enteric methane (CH4) is a by-product from the fermentation of feed in the digestive tract of cattle. The production of CH4 is responsible for the loss of 2% to 12% of the animal’s gross energy intake.

    Interpretive Summary: Effects of bacterial direct-fed microbial mixtures offered to beef cattle consuming finishing diets on intake, nutrient digestibility, feeding behavior, and ruminal kinetics/fermentation profile


    During the finishing phase, a high-energy diet offers benefits related to beef cattle growth and development. However, it is essential to acknowledge that finisher diets are energy-dense and can pose digestive challenges, such as subacute ruminal acidosis.

    Interpretive Summary: Effect of supplementing a Bacillus subtilis-based probiotic on performance, intestinal integrity, and serum antioxidant capacity and metabolites concentrations of heat-stressed growing pigs


    High ambient temperature provokes heat stress in animals, and pigs are highly affected showing low performance, and intestinal integrity and microbiota compromised. Probiotics could help pigs to maintain a healthy intestinal environment.

    Interpretive Summary: Daily dosing of cannabidiol (CBD) demonstrates a positive effect on measures of stress in dogs during repeated exposure to car travel


    Pet dogs often experience stress during routine car travel which can negatively affect both dogs and humans. A range of management and treatment options exist to address this, such as behavior modification, drug therapy, and supplements, yielding mixed results.

    Interpretive Summary: Is there a right time for dairy Alpine goat kid weaning: How does the weaning age of dairy Alpine goat kids affect their growth and behavior?


    In dairy goat kids, there is limited literature available on weaning management practices, despite this period being one of the most stressful events for kids and being associated with measures of poor welfare. This study aimed to compare weaning of dairy goat kids at 6-, 8-, and 10-wk of age to maximize outcome measures of welfare related to growth, feed intake, and behavior.

    Interpretive Summary: Rehydration post-transport: duration of oral fluid therapy on behavior, biochemical measures of hydration, and health of neonatal dairy calves


    Most male calves are sold and transported from the dairy farm soon after birth. Typically, calves are transported without access to milk and/or water, and they often arrive at calf-raising facilities with varying degrees of dehydration.

    Interpretive Summary: FDA releases antimicrobial report


    The United States Food and Drug Administration’s (FDA’s) Center for Veterinary Medicine (CVM) published the 2022 Summary Report on Antimicrobials Sold or Distributed for Use in Food-Producing Animals. This year, the FDA published the results in an interactive dashboard that allows users to interact with the data and create data visualizations using criteria such as antimicrobial drug class, species, and year.

    Interpretive Summary: Some states looking to ban cell-cultured meat


    A House bill introduced in Arizona would prohibit cell-cultured animal products. House Bill 2121 would restrict the production and sale of cell-cultured animal products, citing public health concerns and harm to the ranching industry and state economy. If law, those who violate the legislation would face a penalty of up to $25,000.
