La administración a cerdas de cloprostenol 24 horas después del parto reduce el intervalo destete‑cubrición y mejora la tasa de partos en el ciclo siguiente

Abstract

En este estudio se seleccionaron un total de 448 cerdas productivas de diferentes ciclos (rango de ciclos del 1 al 7), asignando de forma aleatoria 215 cerdas al grupo control y 233 cerdas al grupo PGF2α. A las cerdas del grupo PGF2α se les inyectó 2 ml cloprostenol sódico (87 μg) 24 horas postparto. Se registraron los datos productivos individualizados de las cerdas de cada uno de los grupos. El intervalo destete hasta la cubrición fue de 6.20 ± 0.22 días para el grupo control y 5.72 ± 0.23 para el grupo PGF2α (P<0.01). El porcentaje de cerdas cubiertas antes de 6 días fue superior para el grupo PGF2 frente al control (73.39% vs. 62.33%, P=0.01) y aumentó la tasa de partos en el grupo PGF2α (93.99 vs 86.51 %, P<0.01), pero no se encontraron diferencias para el tamaño de camada (13.54±0.15 vs. 13.53±0.15; P=0.50). La concentración de progesterona se redujo desde la hora 0 a las 72 horas en el grupo PGF2α (0.47± 0.14 vs 0.35±0.13, P<0.05), mientras que la reducción no fue significativa en el grupo control. La metodología y los datos del presente estudio podrían servir de base para diseñar estrategias productivas y tomar medidas específicas para el control de los parámetros reproductivos de las cerdas mejorando tasas de fertilidad y días no productivos.
