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

Journal 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.

Contribution of Fat Adjustment to Residual Feed Intake Estimation in Beef Cattle

Journal of Animal Breeding and Genetics, EarlyView.
ABSTRACT Including fat thickness as a covariate in the regression model used to calculate residual feed intake (RFI) could help preserve carcass quality traits, such as marbling, flavour and juiciness, by accounting for variation in fat deposition.

Genetic Relationships Between Residual Gain and Economically Important Traits in Nellore Cattle

Journal of Animal Breeding and Genetics, EarlyView.
ABSTRACT Sustainable beef production requires identifying animals with superior feed efficiency to reduce environmental impact and production costs. This study aimed to estimate heritability and genetic correlations between residual gain (RG) and growth, reproductive, carcass and feed efficiency traits in Nellore cattle.

Integration of genome and transcriptome reveals core genes and allele-specific expression genetic variants associated with immune differentiation of taurine ancestry dairy cattle from indicine ancestry cattle

BMC Genomics
Background Disease is a key factor to shorten productive lifespan of dairy cattle. Shifting from classical ‘treating existing diseases’ to ‘preventing diseases before they occur’ is a challenge in high-producing dairy cattle.

Avaliação das células luteais de fêmeas taurinas (Bos taurus taurus) e zebuínas (Bos taurus indicus)

, 2014
The aim of this work was to determine the number of bovine luteal cells comparing 80S taurus females with 80S indicus females at the beginning and at the end of estrous cycle. Sixteen corpus luteum were collected in eight 80S taurus cattle and in eight 80S indicus cattle, distributed into four groups.

Updating the forelimb anatomy of the domestic cat (Felis catus, Felidae) based on evolutionary inferences of its muscles and nerves I: Shoulder and brachium

Journal of Anatomy, EarlyView.
In this study, we provide a detailed description of the shoulder and brachium muscles and the brachial plexus of the domestic cat (Felis catus). We identified muscular variants (articularis humeri, coracobrachialis longus, biceps brachii caput breve), clarified the independence of the anconeus medialis muscle from the triceps brachii muscle, and ...
