Response of cyclic and post-partum suckled cows to injections of synthetic LH-RH

Response of cyclic and post-partum suckled cows to injections of synthetic LH-RH

Journal of Reproduction and Fertility 50(2): 203-210

Doses of 125, 250 or 500 mu g LH-RH were injected i/m into suckling beef cows on approximately day 11 of an oestrous cycle synchronized by prostaglandin treatment. There was a positive linear relationship between dose of LH-RH and the area under the measured LH peak. Administration of 500 mu g LH-RH as a single injection to suckling cows 13-32 days after parturition resulted in LH release but failed to induce normal ovarian activity.
