Reproductive qualities of cows against the background of immunocorrection of the organism complex domestic biological products

Method for prevention of postpartum diseases and realization of biological resource potential of reproductive qualities of black-and-pesky livestock due to enhancement of non-specific resistance of steel cows organism by biological preparation of Prevention series. Cows in the control group where no biopreparations were used had an average separation time of 12,6 ± 1,02 h, versus 7,2 ± 0,42 and 5,8 ± 0,66 h in the 1st and 2nd test groups, and were 5,4 and 6,8 h lower respectively. In the postpartum period, subinvolution of the uterus was recorded in three cows in control. Among the animals of the 1st experimental group, 1 case of said pathology was identified, while in the 2nd experimental group this disease was not registered. The dates of onset of the first sexual hunt were shorter in the 2nd experimental group of cows (28,8 ± 0,56 days) by 5,8 days compared to the 1st experimental group (34,6 ± 0,93 days) and by 14,4 days compared to the control (43,2 ± 1,64 days). Against the background of the application of biopreparations, there was a significant decrease in the insemination index of cows of the 1st (1,8 ± 0,24) and 2nd (1,4 ± 0,36) test groups compared to those in control (2,6 ± 0,26)...
