Genetic correlations between mature cow weight and productive and reproductive traits in Nellore cattle

I. C. Regatieri, Boligon, A. A., Baldi, F., and Albuquerque, L. G., Genetic correlations between mature cow weight and productive and reproductive traits in Nellore cattle, vol. 11, pp. 2979-2986, 2012.

We investigated genetic associations between mature cow weight (MW) and weaning weight (WW), yearling weight (YW), weight gain from birth to weaning (GBW), weight gain from weaning to yearling (GWY), weaning hip height (WHH), yearling hip height (YHH), scrotal circumference (SC), and age at first calving (AFC). Data from 127,104 Nellore animals born between 1993 and 2006, belonging to Agropecuária Jacarezinho Ltda., were analyzed. (Co)variance components were obtained by the restricted maximum likelihood method, applying an animal model in a multi-traits analysis.
