Avaliação de matrizes bovinas no Pantanal. [PDF]
, 2013 No início do século XX inicou-sse a introdução de gado zebu, de origem indiana (Bos taurus indicus) no Pantanal. A partir de então, por meio de cruzamentos contínuos, as raças zebuínas absorveram praticamente toda a população do Tucura (Bos taurus taurus)

Cardiovascular Plasticity and Adaptation of High‐Altitude Birds and Mammals
Integrative 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.

Australian Veterinary Journal, EarlyView.In vitro embryo production (IVEP) is now a widely commercialised assisted reproductive technology used in cattle reproduction. The use of follicle‐stimulating hormone (FSH) to superstimulate donor cattle prior to ovum pick‐up (OPU) is generally regarded as an effective strategy to improve oocyte quality, developmental competence and increase embryo ...

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.

Studies on restricted suckling in dual purpose and dairy breed cattle in Mexico [PDF]
, 2005 The aim of this thesis was to investigate the effects of rearing calves by restricted suckling (RS) compared to artificial rearing (AR) in dual purpose and dairy breed cattle in Mexico, milked once or three times a day, respectively.

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.

A Partial African Ancestry for the Creole Cattle Populations of the Caribbean [PDF]
, 2017 Seventy-eight cattle samples from three Creole Caribbean islands and one Brazilian breed were analyzed for sequence variation in the hypervariable segment of the mitochondrial DNA control region. Seventy-three samples displayed Bos taurus haplotypes, and
