Effect of TRH on the secretion of prolactin in ewes at various stages of pregnancy and in non-pregnant ewes during the breeding season and seasonal anoestrus



Effect of TRH on the secretion of prolactin in ewes at various stages of pregnancy and in non-pregnant ewes during the breeding season and seasonal anoestrus



Journal of Reproduction and Fertility 61(1): 149-155



The concentration of prolactin in plasma was measured before and after the injection of thyrotropin releasing hormone (TRH) in 6 pregnant and 6 non-pregnant Border Leicester ewes during the breeding season and seasonal anoestrus. During the first 80 days of pregnancy, the basal concentration of prolactin was low and stable, but thereafter it increased progressively to reach a max. value on day 140.
