Influence of the probiotic additive Basulifor on the growth and morphobiochemical parameters of the blood of heifers up to six months of age

Abstract

The purpose of the work was to study the infl uence of the probiotic additive Basulifor on the growth and morphobiochemical blood parameters of heifers up to six months of age. The experiment was carried out under the conditions of OOO “Agrofi rma Kultura” in the Bryansk region. The effectiveness of the use of the probiotic additive Basulifor as part of the diet for calves in winter was studied; its eff ect on the productivity and morphobiochemical parameters of the blood of calves up to 6 months of age was analyzed. It was found that the indicators of the average daily gain in live weight in heifers in the 2nd and 3rd experimental groups, who received the probiotic additive Basulifor in doses of 0,4 and 0,5 ml/l of milk per day, respectively, were 15,0 and 21,6 % higher. 1 kg of dry matter of the diet for calves contained 10,7 MJ of metabolic energy, 101 g of digestible protein, 5,04 g of lysine, 5,04 g of methionine+cystine, 4,8 g of calcium and 3,73 g of phosphorus. Blood parameters in the two experimental groups were higher than in the control group, but were within the physiological norm. Thus, albumin indices in the 3rd experimental group were higher in relation to the 2nd experimental and 1st control groups by 0,6 and 5,9 abs.%, respectively. The content of α-globulins in the 3rd experimental group also increased in relation to the 2nd experimental and 1st control groups by 1,40 and 0,86 abs.%, respectively. In the 3rd experimental group, the total protein index was 68,03±2,0 g/l and as higher than in the 1st control group and the 2nd experimental group. Thus, the use of the probiotic additive Basulifor in the diet of heifers up to 6 months of age contributed to an increase in the average daily gain in live weight and strengthening the immune status of animals.
