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

open access: yesThe Anatomical Record, EarlyView.
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.

Lures do not increase box‐trapping success of an endangered felid in South Texas

open access: yesWildlife Society Bulletin, EarlyView.
We used a randomized design and linear regression to assess whether visual (compact disc [CD] and ribbon), and olfactory (musk and ocelot urine) lures would increase capture success of three mesocarnivores (ocelots [Leopardus pardalis], bobcats [Lynx rufus], and coyotes [Canis latrans]) with box traps baited with a live bird from December 2023 to April

Cardiovascular Plasticity and Adaptation of High‐Altitude Birds and Mammals

open access: yesIntegrative Zoology, EarlyView.
This schematic depicts the cardiovascular adaptations of mammals and birds to high‐altitude hypoxia. It highlights key phenotypic changes in oxygen transport and cardiac responses, driven by molecular mechanisms including transcriptional regulation and genetic modifications.

Caracterização do estro de novilhas cruzadas (Bos taurus indicus x Bos taurus taurus) por radiotelemetria

open access: yesBrazilian Journal of Veterinary Research and Animal Science, 2006
Embora a técnica de inseminação artificial (IA) apresente inúmeras vantagens, no Brasil é empregada em apenas 7% das fêmeas de corte. Falhas na detecção de estros constituem o principal fator limitante para a obtenção de êxito no emprego da técnica.

Impact of Model Parameterisation and Variance Component Estimates on Genomic Predictions of Carcass Traits in Montana Composite Cattle

open access: yesJournal of Animal Breeding and Genetics, EarlyView.
ABSTRACT This study evaluated the influence of variance component (VC) estimates, obtained from different models and two relationship matrices, pedigree‐based (BLUP) and genomic information‐based (ssGBLUP), on genomic predictions of carcass traits in Montana composite cattle.

Genetic Parameters of Methane Emission, Feed Efficiency, Feeding Behaviour, and Growth Traits in Beef Cattle

open access: yesJournal of Animal Breeding and Genetics, EarlyView.
ABSTRACT Climate change has intensified the need to reduce greenhouse gas emissions, particularly methane (CH4) from enteric fermentation. Genetic selection has emerged as a promising mitigation strategy; however, studies on Bos taurus indicus , especially Nellore cattle, remain limited.
