Abstract: One hundred 6- and 7-year-old Romney ewes were treated for 13 days in January (mid-summer) with intra-vaginal sponges containing 40 mg of 6-methyl-17-acetoxyprogesterone (map). All ewes received 1000 i.u. pregnant mares serum gonadotrophin (pmsg) on the day of sponge removal and fifty ewes received a second 1000 i.u. pmsg 16 days later. The onset of oestrus was synchronized in both treatment groups and was apparently 2 weeks earlier than in twenty untreated ewes. Lambs born as percentage of ewes surviving was satisfactory in all groups being: one dose of pmsg, 94%; two doses of pmsg, 106%; controls 105%. |
