Estimates of covariance functions for growth of Nelore cattle applying a parametric correlation structure to model within-animal correlations
(2005-05-01)
A total of 20,065 weights recorded on 3016 Nelore animals were used to estimate covariance functions for growth from birth to 630 days of age, assuming a parametric correlation structure to model within-animal correlations. ...
