The purpose of our work was to compare the efficiency of two programs for the induction and synchronization of estrous and ovulation in acyclic cows (Ovsynch and Select Synch). To the first batch of 18 cows we have given 2 ml Cystorelin (100 mcg GnRH) on day 0, on day 7th 2 ml Estrumate (500 mcg of ...
