In Vivo Inhibition Followed by Exogenous Supplementation Demonstrates Galactopoietic Effects of Prolactin on Mammary Tissue and Milk Production in Dairy Cows

ABSTRACT: It has been previously shown that the long-term inhibition of milking-induced prolactin (PRL) release by quinagolide (QN), a dopamine agonist, reduces milk yield in dairy cows. To further demonstrate that PRL is galactopoietic in cows, we performed a short-term experiment that used PRL inj...
