The postpartum anestrus period of lowland anoa (Bubalus depressicornis) in captivity

Abstract

Information about the estrus cycle in anoa is particularly important to determine the optimal mating time. The purpose of the study is to determine the duration of the estrus cycle reversion in anoa while they are in their postpartum period. Estrus cycles are determined by observing estrus behavior/signs. Observations were conducted on 1 female postpartum anoa without any lactating activity and 1 female postpartum anoa with lactating activity at Anoa Breeding Center, Manado. The result shows that the postpartum anestrus length periode of the lactating anoa is longer than the one without it. The first anoa was giving a birth on June 2016, estrus reappears 3 months 9 days after. The second anoa was giving a birth on February 2017, estrus reappears 6 months later after the calf weaned. With all these information, the captive center would be able to make a better mating and reproduction plan for the anoa. It is going to rise the percentage of anoa's mating success rate.
