Highly precocious activation of reproductive function in autumn-born goats (Capra hircus) by exposure to sexually active bucks 2019 Access copy available to the general public Unrestricted Goats are seasonal breeders with the main cue controlling the timing of breeding season being photoperiod. Hence, the season of birth impacts puberty onset: spring-born goats reach puberty in autumn, at 7 mo of age, whereas autumn-born goats reach puberty at 1 yr during the next reproductive season. The aim of this study was to determine whether exposure of autumn-born young females to sexually active males could counteract the delay in puberty onset observed in autumn-born goats. Females exposed to sexually active males (n = 8) reached puberty earlier than isolated females (n = 8), with exposed females ovulating at a mean age of 3.5 mo. To our knowledge, such precocious puberty onset obtained through social stimulation has never been described in the literature. Moreover, those exposed females exhibited estrus behavior for most ovulations. Our results indicate that in goats born out of season, exposure to sexually active bucks is a really efficient approach to induce early puberty, suggesting that social interactions could have a crucial impact on the regulation of pubertal transition. info:eu-repo/semantics/openAccess by-nc-nd http://creativecommons.org/licenses/by-nc-nd/3.0/es/ 1.778 2019 0.683 2019 AGRICULTURE, DAIRY & ANIMAL SCIENCE 16 / 63 = 0.254 2019 Q2 T1 Animal Science and Zoology 2019 Q1 ENDOCRINOLOGY & METABOLISM 124 / 143 = 0.867 2019 Q4 T3 Food Animals 2019 Q1 Endocrinology 2019 Q3 info:eu-repo/semantics/article info:eu-repo/semantics/acceptedVersion Chesneau, D.
