Role of LH in the progesterone increase during the bromocriptine-induced prolactin decrease in heifers.

The luteotrophic effect of bromocriptine in heifers was studied to determine if the reported posttreatment increase in progesterone (P4) just before or at the beginning of luteolysis was attributable to loss of a luteolytic effect of prolactin (PRL) or to the stimulation of LH, a known luteotropin. Four treatment groups (n = 7) were used: control (Ct… CONTINUE READING
