Genetic and biological aspects of Zebu adaptability.

The utility and documentation of traits and characteristics of Zebu, Bos indicus, cattle in beef production in the United States are discussed with reference to adaptation. Zebu cattle are uniquely suited to hot climates due to coat, hide, skin and hematological attributes. Form, growth and physiological aspects are unique genetic attributes which are different from those of Bos taurus cattle. ...

Growth and carcass traits associated with GH1/Alu I and POU1F1/Hinf I gene polymorphisms in Zebu and crossbred beef cattle

The objectives of the present study were to estimate the allele and genotype frequencies of the GH1/Alu I and POU1F1/Hinf I polymorphisms in beef cattle belonging to different genetic groups and to determine the effects of these polymorphisms on growth and carcass traits in cattle submitted to feedlot management, an intensive production model. Genotyping was performed on 384 animals, including ...

Running head : Maternal Variances for Growth of Beef Cattle Variance Components due to Direct and Maternal Effects for Growth Traits of Australian Beef Cattle

Variance components for birth, weaning, yearling and final weight in Australian Hereford, Angus and Zebu Cross cattle were estimated by Restricted Maximum Likelihood. Six different animal models were fitted for each trait and breed, ranging from a simple model with animals as the only random effect to the most comprehensive model allowing for both genetic and environmental maternal effects and ...

Estimation of variances due to direct and maternal effects for growth traits of Nelore cattle.

Estimates of (co)variance components and genetic parameters were obtained for birth, 205-d, and 365-d weight for Nelore cattle in Brazil, using single and multiple-trait animal models. Data were from the Brazilian Zebu Breeders Association (ABCZ). Records of 27,549 calves sired by 587 bulls and raised on pasture in 57 herds were analyzed by restricted maximum likelihood fitting an animal model ...
