Genome‐Wide Association Studies for Anogenital Distance and Linear Type Traits in Gir Cattle

Journal of Animal Breeding and Genetics, EarlyView.
ABSTRACT Although linear type traits have been under selection in the Dairy Gir cattle for the past three decades, there are few studies exploring genetic architecture for these traits. The aim of this study was to identify candidate genes for anogenital distance and linear type traits in the Gir breed. For this study, the body measures of rump length (

Diet‐Related Differences Predominate Over Breed‐Associated Differences in Hepatic Lipid Metabolism, Antioxidant Vitamins and Lipid Quality Indices Among Beef Cattle

Journal of Animal Physiology and Animal Nutrition, EarlyView.
ABSTRACT Understanding how nutritional management and genetic background influence hepatic metabolism is important for improving the nutritional quality of bovine products in tropical production systems. This study evaluated breed‐associated differences under a common dietary regimen and diet‐related differences within the Nelore breed with respect to ...

Contemporary Management of Human‐Caused Hybridization in Mammals: A Review

Mammal Review, Volume 56, Issue 4, December 2026.
By reviewing studies on human‐mediated (i.e., anthropogenic) hybridization, we identify key management gaps, including inconsistent identification of admixed individuals, limited population‐level assessments, insufficient social engagement, and unclear management objectives.

Descriptive, comparative, and functional anatomy of the facial musculature in cattle (Bos taurus)

The Anatomical Record, Volume 309, Issue 11, Page 3297-3329, November 2026.
Abstract Facial expressions can provide insight into animal emotions and pain, but no standardized system for assessing the entire facial display in cattle (Bos taurus Linnaeus) exists. The Facial Action Coding System (FACS), originally developed for humans, identifies distinct facial movements based on mimetic muscles.
