Immune status of dairy calves growth with the combined use of probiotics and prebiotics

The aim of the research was to study the immune status of milk-growing calves with the combined use of the probiotic «Vetosporin-Zh» and the prebiotic «Gumi-Malysh». The immune status of calves of the milk growth period was studied on 60 heads of 30-day-old black-and-white Holsteinized calves, which were selected according to the principle of analogues and divided into three experimental groups of 20 heads each. All calves were kept in the same conditions of keeping and feeding. For the calves of the experimental groups, the probiotic «Vetosporin-Zh» and the prebiotic «Gumi-baby» were used for 21 days. As a result of the conducted hematological, biochemical and immunological studies and analysis of the data obtained during the experiment, it was concluded that the combined use of the probiotic «Vetosporin-Zh2 and the prebiotic «Gumibaby » positively affects all types of metabolism in the body of calves. During the experiment, there was an increase in the content of erythrocytes by 1.13 times, hemoglobin by 1.19 times, hematocrit by 1.07 times; total protein 1.27 times, albumin 1.07 times, globulins 1.29 times; the number of Tlymphocytes by 1.08 times, the number of B-lymphocytes by 1.15 times, IgA by 1.12 times, IgM by 1.35 times, IgG by 1.63 times.
