Abstract
In order to determine the efficacy of an analog of LH-RH (FUJINO et al.6) on fertility in dairy cows, single subctaneous injection of 100 μg LH-RH analog or vehicle only were given at the time of insemination. Pregnancy rate was higher in treated cows than in controls (75.0% and 61.3%, respectively), while the difference was not statistically significant.
