Abstract

Fifty cattle were divided into 3 groups (I, II, III) according to FSH-R dosage used to induce superovulation between days 9 and 11 of the estrous cycle. Ova/embryo recovery rate did not differ significantly between groups I and II administered total dosages of 16 and 24 mg, respectively. However, the average number of recovered ova/embryos and transferable embryos was significantly lower in group III (administered a total dosage of 30 mg) (P < 0.05) than groups I and II. These results suggest that intramuscular administration of 16 mg FSH-R over 3 days is sufficient for inducing superovulation in Japanese Black cattle.
