Welfare of beef cattle

EFSA Journal, Volume 23, Issue 7, July 2025.
Abstract This Scientific Opinion provides an assessment of beef cattle welfare focusing on risks related to flooring, water access, nutrition and feeding, high environmental temperatures, lack of environmental enrichment, lack of outdoor access, minimum space allowance and mixing practices. In addition, risks related to pasture and feedlots, weaning of

Effects of Slaughter Age on the Quality of Gannan Yak Meat: Analysis of Edible Quality, Nutritional Value, and GC × GC‐ToF‐MS of the Longissimus Dorsi Muscle

Food Science &Nutrition, Volume 13, Issue 6, June 2025.
Gannan yak meat is a natural green organic food with rich nutritional value. However, the slaughter age of Gannan yaks in the market is older and has lower meat quality. The meat quality of Gannan yak aged 2–4 years is the best, and the content of monounsaturated fatty acids and polyunsaturated fats is the highest.

A Fast and Powerful Empirical Bayes Method for Genome-Wide Association Studies

Animals, 2019
Linear mixed model (LMM) is an efficient method for GWAS. There are numerous forms of LMM-based GWAS methods. However, improving statistical power and computing efficiency have always been the research hotspots of the LMM-based GWAS methods.

Association of the SNP in akirin 2 Gene With Growth and Carcass Traits in Zavot Cattle

Veterinary Medicine and Science, Volume 11, Issue 2, March 2025.
This study explores the association between the *c.188G>A SNP in the 3′‐UTR region of the akirin 2 gene and key growth traits in Zavot cattle, specifically focusing on its impact on average daily live weight gain (ADWG). Using polymerase chain reaction–restriction fragment length polymorphism (PCR‐RFLP) analysis, we identified genotype frequencies of 0.

Tissue expression and predicted protein structures of the bovine ANGPTL3 and association of novel SNPs with growth and meat quality traits

Animal, 2015
Angiopoietin-like protein 3 (ANGPTL3) is a secreted protein that regulates lipid, glucose and energy metabolism. This study was conducted to better understand the effect of ANGPTL3 on important economic traits in cattle.

The Beneficial Impact of Sorting Heavy Cattle at Re-Implant [PDF]

This research examined a simple sorting strategy to reduce the prevalence of heavyweight carcass discounts. Cattle that were identified and sorted off at re-implant had a reduced prevalence of heavyweight carcasses versus unsorted cattle.
