Estimation of genetic parameters for body weights, scrotal circumference, and testicular volume measured at different ages in Nellore cattle
(Journal of Animal Science, 2010-04-01) [Resumo]
Data from 129,575 Nellore cattle born between 1993 and 2006, belonging to the Jacarezinho cattle-raising farm, were used to estimate genetic parameters for scrotal circumference measured at 9 (SC9), 12 (SC12), and 18 (SC18) ...
Evaluation of TFAM and FABP4 gene polymorphisms in three lines of Nellore cattle selected for growth
(Genetics and Molecular Research, 2010-01-01) [Resumo]
We analyzed the polymorphisms TFAM HaeIII, TFAM MboI and FABP4 MspA1I in three Nellore lines selected for growth in order to evaluate how selection affects the frequencies of these polymorphisms and evaluate their association ...
Random regression analyses using B-splines functions to model growth from birth to adult age in Canchim cattle
(Journal of Animal Breeding and Genetics, 2010-12-01) [Resumo]
P>The objective of this work was to estimate covariance functions using random regression models on B-splines functions of animal age, for weights from birth to adult age in Canchim cattle. Data comprised 49 011 records ...
