Resumen

El objetivo fue evaluar el efecto del aumento de peso, el puntaje de condición corporal y el conteo de folículos antrales sobre la fertilidad de vacas inseminadas artificialmente en tiempo fijo. Para este experimento se utilizaron 194 vacas Nelore, pluríparas, entre los 30 y 45 días posparto. Las vacas se pesaron, se evaluó su puntuación corporal y se realizó una ecografía transrectal de los ovarios para identificar el cuerpo lúteo y contar los folículos antrales. Luego, los animales se pasarán por un protocolo hormonal para la realización de la inseminación artificial en tiempo fijo. Treinta días después de la inseminación artificial se volvió a pesar a las vacas y se diagnosticó la gestación mediante ecografía transrectal. La tasa de embarazo no interactuó (P> 0.05) con la puntuación corporal o con la presencia de cuerpo lúteo o con el recuento de folículos antrales. El aumento de peso entre la inseminación artificial y el diagnóstico de embarazo que muestra interacción (P = 0,02) con una tasa de embarazo. La ganancia de peso promedio entre el inicio del protocolo de inseminación artificial por tiempo fijo y el diagnóstico de gestación fue de 9.0 Kg. Las vacas que ganaron hasta 73 kg de peso vivo, tuvieron una mayor tasa de gestación. En conclusión, el aumento de peso entre el momento de la inseminación artificial en tiempo fijo y el diagnóstico de gestación influyó en la tasa de preñez.
