英语. Effect of (GnRH analogue) on post-partum reproductive efficiency in dairy cows. 59 dairy cows from two different farms were divided in two groups of 29 and 30 cows respectively. The 29 cows were treated on day 14 post partum with 20 mcg/head of buserelin, whereas 30 cows (controls) received 5 ml of sterile solution at the same period.
