Methods of standardization of body weight for 205, 365 and 550 days of age were compared. It was used information of animals of the Nellore breed, raised in the Northeast Brazil, and controlled by the Brazilian Zebu Breeders Association (ABCZ). The following methods were compared: MET1 – used by ABCZ; MET2 – individual curves of linear regression for each animal; MET3 – individual curves of quadratic regression; MET4 – individual Brody curve; MET5 – used by the Program of Genetic […]
