Use of weaning management group as a random effect for a more robust estimation of genetic parameters for post-weaning traits in Nellore cattle

V. B. Pedrosa, Eler, J. P., Ferraz, J. B. S., and Groeneveld, E., Use of weaning management group as a random effect for a more robust estimation of genetic parameters for post-weaning traits in Nellore cattle, vol. 13, pp. 7013-7021, 2014.

Data from 69,525 animals were used to compare two types of analyses, one of them having the weaning management group (WEMANG) included as an effect in the contemporary group (F_WEMANG) and the other considering the weaning management group as a random effect, not related to the mathematical model (R_WEMANG) for post-weaning traits.
