摘要：
Non-lactating beef cows (N = 40) were used to determine in vitro production of progesterone by CLs collected on days 6-8, 13-15 and 19-20, following Ovsynch or CIDR ovulation synchronization protocols. Progesterone released by the CL tissues into the medium was measured after 1 h of incubation (control) and after 6 h of hormone treatments (LH, PGF(2alpha) or LH + PGF(2alpha)). In vitro progesterone production did not differ (P > 0.05) between Ovsynch and CIDR ovulation synchronization protocols. Pooled data, irrespective of ovulation synchronization treatments, showed interaction (P < 0.05) between hormone treatment and stage of CL.
