Dried distillers grains with solubles (DDGS) are commonly used as a protein source in finishing cattle diets; however, increased availability of canola meal (CM) from biodiesel production has increased interest in CM as an alternative protein source. This study evaluated the effects of replacing DDGS with CM on nutrient and amino acid (AA) intake, flow, and digestibility.

Full-fat rice bran (FFRB) is a valuable feed alternative, but its available energy values for gestating and lactating sows remain poorly defined. Although the substitution method is widely used to determine the energy content of feed ingredients, the optimal inclusion level of FFRB in sow have not been clearly elucidated.

With policies restricting antibiotic overuse becoming mainstream, farmers are turning to non-antibiotic feed additives to maintain poultry health. Based on this trend, this study evaluated the effects of supplementing wheat-based broiler diets with essential oils-organic acids mixture (EOA) alongside enzyme preparations.

Marbling is the main determinant of beef quality and palatability and is affected by feeding practices. Corn-based diets are commonly fed to cattle to support faster growth and contain high amounts of starch and linoleic acid. Together, these dietary characteristics alter how fats are processed in the rumen, leading to ruminal formation of fatty acids such as trans-10, cis-12 conjugated linoleic acid (t10, c12-CLA) and trans-10 18:1 (t10-18:1).

Canine atopic dermatitis (cAD) typically requires lifelong management using a combination of medications, topical therapies, and allergen-specific treatments. To determine if targeted nutrition can help manage this condition, researchers evaluated the effects of two therapeutic veterinary foods on 39 dogs with cAD over an 8-wk period.

Bovine viral diarrhea virus type 1 (BVDV-1) is a widespread viral infection responsible for large economic losses in cattle herds. In this study, a knock-out (KO) gene edited cell line targeting the Synaptogyrin-2 (SYNGR2) gene was generated via CRISPR-Cas9 to test the role of this gene in BVDV-1 replication.

The domestic turkey is a major species in the international poultry meat industry. Although free-range, organic-like systems are rising in popularity, little research has been conducted in this regard. That is the case of the effect of uncontrolled rearing systems on turkey growth, which is still an understudied field.

On September 16th, the Senate Agriculture Committee met to reconsider passage of the Agriculture Act of 2026. The committee attempted to pass the bill in early August but failed on a party line vote due to the absence of Sen. McConnell (R-KY). McConnell’s return to the Senate in September enabled the committee to advance the legislation by a vote of 12-11.

Preconditioning is a stressful period in which newly weaned steers are vaccinated, dewormed, commingled, and transitioned to a new environment and diets; these stressors compromise immunity, welfare, and growth. Chromium is known to improve glucose metabolism, reduce stress, and increase weight gain in cattle; however, the underlying physiological mechanisms during preconditioning are not fully understood.

Drinking water intake (DWI) for feedlot cattle was assessed by meta-analysis using 35 studies, up to 131 experiments. A wide range of countries, breeds, sex, stages in the feedlot, and environmental conditions were represented. Studies were observational while others evaluated interventions including water quality and shade.

Dietary supplementation with human milk-derived Limosilactobacillus reuteri may help improve the health and growth of weaned pigs by supporting intestinal health and immune functions during the post-weaning period. The dietary probiotic improved growth performance and tended to reduce frequency of diarrhea, suggesting its potential as a functional feed additive for weaned pigs.

A diet with a low protein content is a known effectful measure in reducing the incidences of post-weaning diarrhea. However, a negative side effect of this measure is that the pigs grow slower as their requirements for nutrients are not being met.

Mushroom complex (MC) is a blend of mushroom water extracts including β-glucans and bovine colostrum that may promote immune function and gut health. However, these potential benefits have not been tested in cats. In this study, 20 healthy adult cats were fed a kibble diet for 15 wk.

Omega-3 fatty acids, such as eicosapentaenoic acid (EPA) and docosahexaenoic acid (DHA), help regulate inflammation, support immune function, and contribute to maintaining normal physiological processes. This study evaluated the effects of increasing dietary EPA and DHA intake from fish oil in healthy adult, large-breed dogs.

Chronic fear and anxiety experienced by pet dogs can negatively affect their welfare, although the physiological mechanisms underlying these states remain poorly understood. The objective of this study was to explore metabolites associated with fearfulness in dogs.

Milk from cows carrying the A2 variant of the β-casein protein has attracted increasing interest because it may be easier to digest than conventional milk. As a result, many dairy farms are progressively selecting cows with the A2A2 β-casein genotype. However, little is known about whether genetic variation in genes expressed in the mammary gland could be detected specifically in A1A1 or A2A2 groups.

Pellet quality is a major concern for commercial feed mills as it influences the production efficiency of pelleted feed, as well as downstream animal performance. The Pellet Durability Index (PDI) is commonly used to measure pellet quality. However, since numerous variables can affect PDI, it is challenging for commercial feed mills to consistently achieve the desired PDI.

Intake of low-quality forage (LQF) in the absence of protein supplementation fails to meet ruminal microbial nitrogen requirements, decreasing forage utilization and animal performance. Supplementation of both protein and starch is used to ameliorate the negative effects of LQF; however, the effect of supplementation on ruminal microbial communities is not well-understood.

Reproductive management in sheep often involves estrus synchronization using intravaginal sponges. While the effects on adult ewes are known, the impact on nulliparous ewe lambs remains unclear. This study characterized the vaginal bacteria of 22 Latxa ewe lambs at three stages using 16S rRNA gene amplicon sequencing: baseline, after initial physical handling (hymen rupture), and after sponge removal.

Odd-chain fatty acid metabolism has recently become a topic of interest for human health. This interest has followed observations of inverse associations between pentadecanoic acid (C15:0) and/or heptadecanoic acid (C17:0) with cardiovascular disease, type 2 diabetes mellitus, and hypertension risk.
