RIVAS-MUNOZ, Raymundo et al. Effect of a short-term prostaglandin protocol upon synchronization and reproductive outcomes in cyclic goats. Abanico vet [online]. 2021, vol.11, e110.  Epub 11-Out-2021. ISSN 2448-6132.  https://doi.org/10.21929/abavet2021.14.

The aim of the study was to evaluate the reproductive response of cyclic goats in northern Mexico (26° N) subjected to two administration schemes of prostaglandins (PG; 5 days vs. 10 days) to synchronize estrus response. Cyclic adult French-Alpine goats were allocated in two groups. Group G5 (n = 10), received the first PG-injection (0.2 ml; 160 μg cloprostenol) on d -5 and group G10 (n = 10) received the first PG-injection on d -10. Both groups received the second PG-injection on d 0. General reproductive outcomes after second PG-administration were similar (P>0.05) between treatments. Estrus response= 60% for both groups, estrus latency= 68h vs 52h, ovulation= 80% vs 60% (G5 vs G10, respectively; P>0.05). Since no differences occurred between groups, administration of the G5 treatment seems to be an interesting short-term synchronizing alternative protocol in that it generated important reproductive outcomes.
