(2013) Selection of young ewe lambs according to their antral follicular count: response to exogenous hormonal stimulation and fertility at first breeding season. In: Atti X Congresso Nazionale So.F.I.Vet, 8-9 luglio 2013, Taormina (Messina). (Submitted)
Anti-Mullerian Hormone (AMH), Antral Follicular Count (AFC) and the response to exogenous hormonal stimulation have been used, in adults, as suitable markers to determine the ovarian reserve (1-4), to predict oocyte quality (5,6) and a wide variety of fertility indices (6-9). This investigation aims to evaluate if animals selected according to their High or Low AFC at an early prepubertal age show different responses, in the number of follicles and AMH plasma levels, to exogenous hormonal stimulation; to verify whether differences are maintained over time until puberty; and to observe possible variations on fertility at first breeding season.
