The article describes a method of preventing postpartum obstetric-gynecologic diseases and improving the reproductive function of cows by increasing the nonspecific resistance of the organism with the use of Prevention-N-B-S bio-preparation. For the first time the newly developed bio-preparation was injected to cows of Experimental Group 2 intramuscularly with a dose of 10 ml 35-30, 15-10 and 10-5 days before the expected calving date, while Dorogov’s antiseptic stimulant 2 fraction and Eleovit at the ratio of 1:9 were injected to the animals of Experimental Group 1 60 days before the estimated calving dates. It was established that the first estrus of Experimental Group 2 cows (28.8 ± 0.56 days) was 5.8 and 14.4 days earlier than that of the same-age cows of Experimental Group 1 (34.6 ± 0.93 days) and the Control Group (43.2 ± 1.64 days). The service period in Experimental Group 1 (64.6 ± 1.62 days) and Experimental Group 2 (57.8 ± 1.50 days) became shorter, comparing to the Control Group (89.2 ± 3.02 days). Use of bio-preparations in critical pregnancy periods of cows reduced the risks of subinvolution of uterus, endometritis and mastitis in the postpartum period and increased reproductive qualities of cows. The effect was most apparent when Prevention-N-B-S bio-preparation was used.
