Abstract
Fifty eight dairy cows without detectable aberrations of the genital tract were injected with 250-mu-g Gonado relin the twelfth day after the third insemination. Fifty two cows selected in the same way (control group), received an injection with physiologic saline. The pregnancy rate at third insemination was 52% in both groups. Only 17 of the 53 non-pregnant cows (experimental and control group) were inseminated for the fourth time after a normal cycle length. The pregnancy rate of this insemination was also equal for the experimental and the control group. Milk progesterone values obtained from 70 animals showed that half of the non pregnant cows that were not seen in oestrus 3 weeks after the third insemination had a prolonged cycle. In the other half oestrus was not noticed by the herdsman. Also for these parameters there were no differences between both groups. The conclusion is that a GnRH-injection given 12 days after the third insemination does not improve fertility of repeat breeder cows.
