Effect of 17β-estradiol on milk production, hormone secretion, and mammary gland gene expression in dairy cows.

Journal of dairy science Dec 21, 2017
Estradiol inhibits milk production in dairy cows. The present study evaluated the effect of 17β-estradiol (E2) injections on prolactin (PRL) secretion and the mammary gland response to this hormone. Eight mid-lactation cows were used in a crossover d...
