DETERMINACIÓN DE UN ÍNDICE DE SELECCIÓN PARA EL PESO AL NACER Y AL DESTETE EN GANADO BOVINO DE LA RAZA BRAHMAN
Objective. To Estimate a selection index for birth weight and weaning weight in Brahman cattle on the north coast of Colombia. Material and methods. To calculate this index we estimated the components of variance between and inside of the reproducer, and the genetic and phenotypic covariances betwee...
