Determinación de un índice de selección para el peso al nacer y al destete en ganado bovino de la raza brahman

Abstract

Objetivo. Estimar un índice de selección para el peso al nacer y al destete en ganado bovino de la raza Brahman en la “Hacienda Mundo Nuevo”, Costa Norte Colombiana. Materiales y métodos. Para el cálculo de este índice fue necesario estimar los componentes de varianza entre y dentro de reproductor y las covarianzas genéticas y fenotípicas entre las características en estudio utilizando el procedimiento MIXED de SAS. Resultados. El índice estimado fue: I=X1-0.4286X2 , obteniendo así una máxima correlación entre el fenotipo agregado y genotipo agregado, convirtiéndose en una herramienta de mejoramiento genético para hacer el proceso de selección mas técnico y eficiente y lograr un mayor progreso genético por unidad de tiempo. Conclusiones. Se recomienda la utilización de los animales de mejor índice, ya que existe correlación entre el índice y el genotipo agregado.
