Genomic Analysis of Taurine and Indicine Ancestry in the Montana Tropical Composite Population

Journal of Animal Breeding and Genetics, EarlyView.
ABSTRACT The Montana Tropical cattle, a Taurine and Indicine composite, were developed in Brazil since 1994 and were based on crossing four biological types of cattle: zebu (mainly Nelore), tropical adapted taurine (mainly Senepol and Romosinuano), British taurine (mainly Angus) and continental taurine (as Charolais, Simental and Limousin).

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

Journal 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.

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

Brazilian 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.

Morphological dimorphism in the Y chromosome of "pé-duro" cattle in the Brazilian State of Piauí

Genetics and Molecular Biology, 1999
"Pé-duro" (hard foot) is a rare breed of beef cattle of European (Bos taurus taurus) origin, originated in northern and northeastern Brazil. Y chromosome morphology, outer genital elements and other phenotypic characteristics were examined in 75 "pé-duro"

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.

Expressão de genes ligados à maciez da carne em bovinos da raça Nelore. [PDF]

, 2015
Dentre as características da carne, a maciez é a mais desejada pelo consumidor. Bovinos de origem Bos taurus indicus são conhecidos por produzirem carne de menor maciez quando comparado às raças de origem taurina.
