The fat composition and mineral content of beef influences both its taste and nutritional value. This study seeks to understand the relationship between meat quality and the nutritional value of beef from Brangus cattle. Animals varied greatly in their levels of essential omega-6 and monounsaturated fat.

Premium pet foods often include chicken slurry, which is thought to be superior to chicken meal but is not well-tested. This study aimed to determine how chicken slurry inclusion level affected the apparent total tract digestibility (ATTD) and palatability of extruded dog foods, and gastrointestinal health indices of dogs.

Heat stress and its effects on milk production are commonly related to the effects of climate change. In the temperate regions, cold winters and mild summers have historically provided some buffering effect and maintained milk production. However, a measurable effect of heat stress on milk production was found, with its severity and period dependent on microclimates and the rate of increase dependent on climate change.

This study explored how diet, specifically dietary fiber, and the timing of weaning affect the wellbeing of pigs. The sows and their offspring were fed two types of fiber: low-fermentable hay and high-fermentable sugar beet pulp, in either fine or coarse form. Conventional weaning with late weaning of piglets was also compared.

Poultry encounter challenges in synthesizing endogenous enzymes to completely degrade antinutritional factors, including phytic acid (PA) and nonstarch polysaccharides (NSP). These exogenous enzymes are present in plant-based feed ingredients, which encapsulate nutrients and adversely affect their digestion in the gastrointestinal tract (GIT).

Dairy cows face significant metabolic challenges during the different phases of the production cycle. One of their primary issues revolves around meeting the elevated energy demands, encompassing essential maintenance requirements and the energy required for milk production.

This study investigates the relationship between genes and metabolites in sheep ovaries and blood. The analysis revealed that glutathione pathways are active in both the ovary and blood, which indicates a possible exchange of metabolites between these 2 tissues.

Probiotics, live microorganisms, postbiotics, metabolites of probiotics, or the components that result from probiotic activity, help to maintain a healthy gut environment and are beneficial for general health and well-being. Minimal research has been conducted on the effects of probiotics and postbiotics on canine health.

Specific components of yeast may affect gut microbiota and health. Corn fermented protein (CFP) is a co-product from ethanol production which contains approximately 20% to 25% yeast. In this work, 11 cats were fed diets containing no yeast (T1) and either 3.5% brewer’s dried yeast (T2), 2.5% brewer’s dried yeast plus 17.5% distillers dried grains with solubles (T3), or 17.5% CFP (T4).

Octobers edition of Washington Roundup includes three summaries: Pressure Mounting on Agriculture Committee Leaders to Complete Farm Bill, Draft Dietary Guidelines Raise Meat Industry Concerns, and FDA Publishes 2023 Summary Report on Antimicrobials Sold or Distributed for Use in Food-Producing Animals.

A recent Nature career feature article (DePaul, 2024) focused on the roles of science policy advisors, noting “Many researchers think that science policy is a total snoozefest.” Four science policy specialists, from Spain, Canada, United States, and India, shared their insights for the article.

Teresa A. Davis, PhD, ASAS Fellow, former ASAS President, and past chair of the ASAS Public Policy Committee was elected as a new member of The National Academy of Medicine (NAM). The academy announced the election of 90 regular members and 10 international members during its annual meeting on October 21, 2024.

Gastrointestinal nematodes or worm parasites in grazing livestock and horses are a major health challenge due to worldwide prevalence of the parasite’s resistance to available dewormers. Pharmaceutical companies have limited interest in development of new products because of cost and the likelihood that worms will develop resistance to new compounds and continue to market older dewormers.

Gastrointestinal nematodes (GIN) are the most important health issue for small ruminants in many world regions. The GIN parasitism causes welfare concerns and severe economic losses related to reduced productivity, cost of treatment, and, eventually, mortality.

Cattle, sheep, goats, and their associated industries are a vital component in the development of rural areas and sustainable land use strategies in Europe. With 77 million bovines and 74 million sheep and goats in the EU (Eurostat, 2023), ruminant production is deeply linked to European culture.

Egg production in the United States has changed significantly in the last century. From the 1920s to the 1960s, egg production underwent a significant evolution, driven by advancements in breeding and husbandry practices (Kidd and Anderson, 2019).

Developing deworming programs for horse farms based on scientific evidence has become more challenging as the concern over the development of anthelmintic resistance (AR) by internal parasites has continued to grow over the past few decades. The once simple recommendation of “deworm horses every two months” has become outdated and is strongly discouraged by many experts in the field as it is believed to hasten the development of AR in parasites which renders commonly used deworming drugs less effective.

Beef cattle are often provided supplements to compensate for seasonal nutrient deficiencies. However, one of the challenges to strategic supplementation is controlling individual intake variation. The most common method to regulate intake of self-fed supplements is the use of salt.

The growing aquaculture production can greatly affect the aquafeed industry and cause problems, especially in providing fish meal (FM) for diets. Price and production instability in FM can restrict producers’ ability to produce aquafeed. Therefore, it is advised to use plant proteins such as soybean meal (SBM), which has high protein, reasonable price, and relatively balanced amino acids profile.
