Methods of reducing embryonic losses in diary cows and their clinical effectiveness
Abstract
In experiments on 375 lactating cows, the effectiveness of the use of progestogens, gonadoliberins and gonadotropins was evaluated to reduce embryonic losses and delay the development of the embryo and fetus. The possibility of increasing their effectiveness by combining the prescription with the biologically active preparation Sat-Som and the selenium-containing drug Selemag is shown. Prophylactic efficacy increased from 8.3 to 16.3% to 18.5-35.7%. New approaches to increasing the efficiency of insemination of cows by the assignment of recombinant bovine interferon-tau and a nonselective cyclooxygenase inhibitor Flunixin meglumin prolonging the progesterone-synthesizing function of the corpus luteum are proposed. The prospects of their application are shown.
