Resumo: The present study evaluated the efficacy of two protocols for estrus synchronization with different intervals in order to use them in artificial insemination (AI) in Saanen and Alpine multiparous goats in June (end of the natural mating season). The animals were allocated into two groups, according to breeding, parity, and body condition score to receive two doses of 37.5 ?g d-cloprostenol (Prolise®, ARSA SRL, Buenos Aires, Argentina) latero-vulvar 7.5 (n=23) and 11.5 (n=25) days. No animal became pregnant after NM. In AI animals, conception rate was 69.2% (9/13) for T7.5 and 70.6% (12/17) for T11.5 (P> 0.05). Even at the end of the breeding season, the protocols were able to synchronize a significant percentage of animals in a short window of time, resulting in a high conception rate after AI.
