    Interpretive Summary: 5-hydroxytryphophan mitigates ergot alkaloid-induced suppression of serotonin and feed intake in cattle


    Some grass species have a symbiotic relationship with an endophytic fungus that produces toxic ergot alkaloids which have detrimental impacts on herbivores. Ergot alkaloids have a significant impact on livestock production causing annual loss to the livestock industry that likely exceeds $1 billion.

    Interpretive Summary: Improving feed intake and rumen fermentation in lambs using mixed-dimensional attapulgite clay to adsorb naturally occurring mycotoxins


    The issue of mycotoxin-contaminated animal feed has consistently presented a significant challenge in relation to animal health and production. The mixed-dimensional attapulgite clay (MDA) has been proven effective in binding polar mycotoxins such as aflatoxin, while also effectively adsorbing hydrophobic or weakly polar mycotoxins such as zearalenone (ZEN) and ochratoxin.

    Interpretive Summary: Processing of corn-based dog foods through pelleting, baking and extrusion and their effect on apparent total tract digestibility and colonic health of adult dogs


    Dog foods were produced via extrusion, baking, and pelleting to yield increasing amounts of starch resistant to digestion (resistant starch [RS]). The foods were compared to a negative dextrose control that contained dextrose in place of starch.

    Interpretive Summary: Maternal protein supplementation during mid-gestation improves offspring performance and metabolism in beef cows


    In tropical conditions, beef cows on pasture often experience protein restriction during mid-to-late gestation, potentially impacting offspring development negatively. To address this, we investigated the effects of strategic protein supplementation for pregnant beef cows fed low-quality forage during mid-gestation on the postnatal growth trajectory of their offspring.

    Interpretive Summary: Sustainable pig diets: partial grain replacement with former food products and its impact on meat quality


    Pigs are ideal species to convert food losses, also named former food products (FFPs), into animal proteins. The present study investigated the impact of incorporating sugary and salty FFPs into the diets of growing and finishing pigs on meat quality and its sensory characteristics.

    Interpretive Summary: Effects of dietary protein level on intestinal function and inflammation in nursery pigs


    High dietary crude protein (CP) is thought to antagonize nursery pig enteric health. Feeding high CP diets to nursery pigs did not exacerbate intestinal health or inflammation, and overall, protein level in the diet has little impact on animal health and performance.

    Interpretive Summary: Levodopa attenuates the feed intake reduction caused by ergot alkaloids in cattle


    Fescue has become the dominant cool-season perennial grass in the southeastern region of the United States and is also found in other countries. Endophytes from a plant–fungus symbiotic relationship produce toxic alkaloids that have caused significant annual economic losses to the livestock industry.

    Interpretive Summary: Supplemental trace minerals as complexed or inorganic sources for beef cattle during the receiving period


    Issues associated with health and management of newly received cattle continue to pose significant animal welfare and economic challenges for the beef industry. Diagnosis of bovine respiratory disease, accompanied with poor growth performance, can be addressed by nutritional intervention in receiving cattle.

    Interpretive Summary: Genetic parameters for carcass traits of progeny of beef bulls mated to dairy cows


    Low-cost genotyping platforms and sexed-semen have enabled the production of high breeding value dairy replacement heifers from a fraction of the herd representing the most elite cows. The remainder of the cow herd can be bred to beef bulls using male-sexed-semen.

    Interpretive Summary: Lightweight model-based sheep face recognition via face image recording channel


    Accurate identification of individual sheep is a crucial prerequisite for establishing digital sheep farms and precision livestock farming. In this study, we developed a lightweight sheep face recognition model, YOLOv7-SFR. Utilizing a face image recording channel, we efficiently collected facial images from 50 experimental sheep, resulting in a comprehensive sheep face dataset.

    Interpretive Summary: Parental betaine supplementation promotes gosling growth with epigenetic modulation of IGF gene family in the liver


    The goose industry plays important roles in economics, cultures, and ecosystems, yet the low laying and growth rates of many indigenous breeds hinders the development of the goose farming. Betaine, an important methyl donor, is commonly used as a feed additive in livestock and poultry to enhance animal growth.

    Interpretive Summary: The effects of including sprouted barley with alfalfa hay in the diet on ruminal health and performance of cow-calf pairs


    Climate variability and uncertainty associated with weather patterns can greatly impact feed security for cattle producers. Flooding, drought, and temperature extremes can reduce a farmer’s ability to produce a consistent crop, resulting in feed prices that can fluctuate greatly.

    Interpretive Summary: Effect of continuous or intermittent feeding of ergot contaminated grain in a mash or pelleted form on the performance and health of feedlot beef steers


    Produced by the fungus Claviceps purpurea, ergot alkaloids (EA) are toxic to beef cattle when consumed and can lead to reduction in feed intake and growth performance, vasoconstriction of the blood vessels, hyperthermia, damage to extremities (ears, tails, and hooves) and in severe cases, death.

    Interpretive Summary: Efficacy of a novel multi-enzyme feed additive on growth performance, nutrient digestibility, and gut microbiome of weanling pigs fed corn–wheat or wheat–barley-based diet


    There is a pressing need to enhance livestock production efficiency to meet the growing global demand for meat. Carbohydrases and proteases are enzymes typically added to swine diets to improve nutrient utilization, leading to better growth rates and feed efficiency. This ultimately contributes to sustainable and economically viable pig farming.

    Interpretive Summary: Unveiling the Genetic Landscape of Feed Efficiency in Holstein Dairy Cows: Insights into Heritability, Genetic Markers, and Pathways via Meta-Analysis


    A thorough understanding of the genetic factors that influence the feed efficiency of dairy cows is a prerequisite for planning and implementing selective breeding programs. Therefore, a systematic review of reported heritability, genetic markers, and biological pathways affecting FE-related traits in Holstein dairy cows was conducted and followed by a meta-analysis.

    12th Nutrient Requirements of Swine Committee is Underway


    The National Academy of Sciences, Engineering and Medicine (NASEM) has established the committee to develop the 12th Nutrient Requirements of Swine. The committee has already met in person twice and on-line three times with annual in-person and monthly on-line meetings scheduled for the future. NASEM’s charge to the committee is to “conduct an in-depth review of the scientific literature on the nutritional needs of swine and prepare a report that revises and updates the 11th edition of Nutrient Requirements of Swine.”

    Interpretive Summary: Final rule issues for the Packers and Stockers Act


    The United States Department of Agriculture (USDA) has announced the finalization of the Inclusive Competition and Market Integrity Under the Packers and Stockyards Act. The final rule will be effective for 60 days following publishing in the Federal Register and is designed to establish clearer, more effective standards under the Packers and Stockyards (P&S) Act for prohibited practices relating to discrimination, retaliation, and deception in contracting.
