Repeated treatment with vaginal sponges and PMSG - a study in 19 flocks

, : Repeated treatment with vaginal sponges and PMSG - a study in 19 flocks. Chevre ( 189): 19-21

Oestrus was synchronized in 368 French Alpine and 272 Saanen primiparous and multiparous goats by treatment with FGA- impregnated sponges for 11 days, and treatment with 400-600 IU PMSG and 50 mu g cloprostenol on day 9 of sponge treatment, and all were inseminated with frozen semen 43-45 h after sponge withdrawal. 98% of goats exhibited oestrus; 59.2, 22.0, 11.7, 3.8 and 1.4% did so <25, 25-30, 31-36, 37-48 and 49-72 h after sponge withdrawal, and 66.5, 61.0, 37.3, 25.0 and 22.2% of in the above 5 groups resp. conceived. A significantly greater percentage of goats aged 3.5-4.5 yr and treated 3-5 times showed oestrus >30 h after sponge withdrawal, compared with older goats treated the same number of times or goats of all ages treated <3 times, and the CR for these goats was 52% vs. 59 for goats of the same age treated <3 times. Analysis of blood samples collected from 297 goats revealed that the interval between sponge withdrawal and first signs of oestrus averaged 26.2+or-4.9 h for with a blood PMSG concentration of <5% vs. 33.0+or-9.1 h for those with a concentration of >5% (P<0. 001), and the CR was 61.5% vs. 43.8 (p<0.05). It is suggested that goats failing to conceive after the first treatment should not be be given further hormone treatment the same year in order to avoid the development of anti-PMSG antibodies.
