Ranking of Nellore animals in cattle championships: genetic parameters and correlations with production traits

E. A. Simielli Filho, Mercadante, M. E. Z., Silva, J. A. I. I. Vasconc, and Josahkian, L. A., Ranking of Nellore animals in cattle championships: genetic parameters and correlations with production traits, vol. 13, pp. 5722-5731, 2014.

Records of 17,141 Nellore cattle participating in cattle championships, born from 1994-2009, were used to estimate genetic parameters between animal rank in cattle championships, evaluated from weaning to 36 months of age as repeated traits, and growth, fertility, and carcass traits, evaluated at 365 days of age as single traits. Two traits were defined for animal rank in cattle championships: value 1 was attributed to animals ranked from 1st to 3rd place within the age category, and value 0 was assigned to the remaining animals (TOP3).
