REPRODUCTIVE TRAITS SELECTION IN NELORE BEEF CATTLE

Abstract – The objective of this work was to estimate the allelic and genotypic frequencies of CAST / Xmn I, a calpastatin gene polymorphism, and CAPN530, a calpain 1 large

The genetic variability for growth traits and population structure of Nelore cattle in Northern Brazil indicates that this population has potential for genetic gain by

The purpose of this study was to (i) estimate genetic parameters for a number of reproductive and vegetative traits of physic nut (based on phenotypic

ruziziensis, it was estimated the parameters heritability and genetic and phenotypic correlations between the traits associated with flowering, and the traits responsible for

Gene IRF1 emerges as a candidate for harbouring mutations associated to reproductive traits measured early in life, in both Brahman and Tropical Composite cows. Gene IRF1

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

Heritabilities and genetic correlations in a Canchim beef cattle herd were estimated using data on the following traits: male scrotal circumference at twelve months (SC12); days

Resistance of beef cattle heifers to the cattle tick Boophilus microplus was evaluated by artificial infestation of 66 beef cattle heifers of the following genetic groups: 16
