The luteinizing hormone response of pregnant cows and their calves to synthetic luteinizing hormone releasing hormone


Journal of Reproduction and Fertility 46(1): 235-237
The luteinizing hormone response of pregnant cows and their calves to synthetic luteinizing hormone releasing hormone
Pregnant cows and their calves responded to LH-RH [luteinizing hormone-releasing hormone] treatment, but the time course of the response was different, the newborn calves with undeveloped gonads responding in a similar way to castrated animals. Peak levels of LH after LH-RH treatment in the pregnant cows and their calves were lower than those reported for the mature non-pregnant animal, suggesting pituitary refractoriness during the later stages of pregnancy.
