AB  - An experiment was designed to investigate the ovarian activity by which progestin administration induces puberty in Awassi ewe lambs. Prepubertal lambs were fed to provide approximately 0.125 mg/ewe lamb MGA twice daily for a 12 d period (MGA; n = 14) or to serve as untreated controls (CONT; n = 14). Laparoscopic examinations of ovaries were conducted on days 7 and 8 after last MGA feeding. The percentage of ewes having active ovary on days 7 and 8 d after last MGA feeding was significantly higher (p<0.05) for treated (56%) than for control ewes (11%). We suggest that MGA withdrawal accelerates follicle growth to the preovulatory stage and puberty was able to be induced in 9 months old Awassi ewe lambs with MGA treatment for 12 days.
