title: [Effect of various drugs and enzymes on the quality of deeply frozen bull sperm].
abstract: In vitro experiments were carried put to test the effect of beta-glucuronidase, ensaprost-phi, and carbocholin-proserin on a total of 725 samples of deeply-frozen bull semen in 8 nutrient media. Studied were the motility, thermal resistance, and oxygen consumption of spermatozoa. The first two indices showed highest values with the use of medium No 2 consisting of 2.8 per cent solution of sodium citrate and 4 gamma ensaprost-phi, and the consumption of oxygen was highest in medium No 1, consisting of 2.8 per cent solution of sodium citrate and 50 U beta-glucuronidase. Biologic experiments with 2106 cows were also carried out. The conception rate was 9.03 per cent higher that that of the control animals at first insemination.
