THE EFFECTIVENESS OF USING DIFFERENT FORMS OF PROBIOTIC SUPPLEMENT BASULIFOR TO CALVES DURING THE PREWEANING PERIOD

Abstract

Feeding of probiotic supplements Basulifor to calves up to six months of age in dry (C) and liquid (G) forms containing strains of Bacillus subtilis and Bacillus Licheniformis at 14.7-10.7 MJ of metabolic energy per 1 kg of dry matter of feed mixtures included in the diet had a positive effect on productivity and morphobiochemical parameters of blood. In the first scientific and economic setting, with the inclusion into the diet of calves from the second group of 15 g and from the third group of 20 g Basulifor-S per head per day, the average daily gains in live weight increased by 8.5% and 19.3%, respectively, relative to the control group, the increase in which was 686.0 ± 8.8g. In the second scientific and economic setting, when giving calves of the second and third experimental groups, respectively, 0.4 ml and 0.5 ml of Basulifor-Zh per liter of whole milk per head per day the average daily gains in live weight increased by 15.2% and 21.6% against the control, and amounted to 730±29.5g and 770±23.3 g. Morphobiochemical blood parameters were in the reference values of the norm in both settings. In the first setting, the blood counts did not differ significantly in all groups. In the second setting, an increase by 16.09% in the concentration of erythrocytes in the second experimental group and by 17.24% in the third was found, with a simultaneous decrease in the level of leukocytes by 22.16% and 18.29%, respectively, and an increase in the globulin fraction of proteins when using the liquid form of the probiotic supplement Basulifor-Zh, which allows us to talk about optimizing metabolism and increasing productivity.
