RESUMEN

La predicción de la composición corporal del ganado, tanto vivo como en canal, es importante en todos los segmentos de la industria de la carne; ya que tiene utilidad en: desarrollo de pruebas de progenie, evaluación de la canal, en experimentos de nutrición, en la estimación de los requerimientos de energía, en la asignación en forma individualizada de el costo por concepto de alimentación y en la producción de animales con la composición corporal optima, para obtener una remuneración económica máxima. La grasa es el componente corporal más variable en cantidad y distribución durante el crecimiento, por lo tanto, ésta se utiliza para determinar la composición corporal. El peso corporal de los bovinos, cuando llegan al corral de engorda (peso inicial), influye sobre el peso y características de la canal utilizadas para la estimación de la composición corporal. Los animales con peso inicial liviano (becerros) presentan una mayor cantidad de grasa subcutánea comparados con los (pesados) añeros. Por esta razón, no se deben utilizar las ecuaciones hechas con añeros para determinar la composición corporal de becerros para evitar una sobreestimación.
