Oestrous and conception rate in Saanen goats synchronized with medroxyprogesterone acetate (MAP) at two times of the year

Oestrous and conception rate in Saanen goats synchronized with medroxyprogesterone acetate (MAP) at two times of the year

The study aimed to evaluate the rates of visual oestrous and conception in Saanen goats subjected to oestrus synchronization at two seasons of the year. Hormonal synchronization was done using an intravaginal sponge impregnated with medroxyprogesterone acetate (MAP), for 11 days. In addition, 48 hours before sponge removal, 300 IU equine chorionic gonadotropin (eCG) and 125 µg cloprostenol were administered. The goats that showed heat were mounted by fertile males. The pregnancy diagnosis was done 60 days after the service by transrectal ultrasound. The rate of presentation of heat was 86.7 and 96.7% for the anoestrous season (January-February) and the cyclicity season (March-April), respectively, without significant difference between periods. The conception rate was 88.5 and 62.1% for the periods January-February and March-April, respectively (p<0.05). It is concluded that the use of MAP impregnated intravaginal sponges for the synchronization of oestrus in Saanen goats is effective, regardless of the time of year.

El estudio tuvo como objetivo evaluar las tasas de presentación de celo y concepción en cabras Saanen con sincronización del estro en dos épocas del año. La sincronización hormonal se hizo mediante una esponja intravaginal impregnada con acetato de medroxiprogesterona (MAP), durante 11 días. Además, 48 horas antes del retiro de la esponja se administró 300 UI de gonadotropina coriónica equina (eCG) y 125 µg de cloprostenol. Las cabras que mostraron celo fueron sometidas a un empadre controlado por monta natural. El diagnóstico de gestación se hizo 60 días después de la monta mediante ultrasonografía transrectal. La tasa de presentación de celo fue de 86.7 y 96.7% para la época de anestro (enero-febrero) y ciclicidad (marzo-abril), respectivamente, sin diferencia significativa entre periodos. La tasa de concepción fue de 88.5 y 62.1% para los periodos enero-febrero y marzo-abril, respectivamente (p<0.05). Se concluye que el uso de esponjas intravaginales impregnadas con MAP para la sincronización del estro en cabras Saanen es eficaz, independientemente de la época del año.
