Random regression models with B-splines to estimate genetic parameters for body weight of young bulls in performance tests

ABSTRACT The objective of this study was to estimate genetic parameters for body weight of beef cattle in performance tests. Different random regression models with quadratic B-splines and heterogeneous residual variance were fitted to estimate covariance functions for body weights of Nellore and cr...
