Intervalo entre partos en el vacuno de carne extensivo de raza retinta

Abstract

La eficacia reproductiva en el vacuno depende, entre otros parámetros, del intervalo entre partos. Esta variable está considerada una de las más importantes para la rentabilidad de la explotación en el caso del vacuno de carne en régimen extensivo. En este trabajo se estudia la influencia de distintos factores sobre el intervalo entre partos en la raza retinta mediante el análisis de 7356 partos de 1803 vacas pertenecientes al Núcleo de Control de Rendimientos de la Asociación de Ganaderos de esta raza. Nuestros resultados muestran que este parámetro se ve afectado principalmente por la ganadería, la campaña ganadera, época, sus interacciones y el tipo de parto, no existiendo relación significativa entre este período y el peso al destete de los terneros El valor medio obtenido para todo el intervalo analizado ha sido de 16,144 ± 0,086 meses y la heredabilidad estimada para este carácter fue de 0,1104 ± 0,08.
