Abstract

THE INFLUENCE OF PROBIOTIC BACILLUS LICHENIFORMIS ON SELECTED METABOLIC PARAMETERS OF CALVES

Link R. and *Zigo F.

ABSTRACT

The aim of the study was to evaluate the effect of Bacillus licheniformis administration on selected metabolic indices in blood of calves. We also compared phagocytic activity of neutrophils between groups. Eighteen calves, 7–8 days old, were included in the trial and they were divided into three groups. Experimental groups were given 200 ml of Bacillus licheniformis culture twice a day for ten days. Calves in the first group (n = 6) got culture at the concentration of 3x108. ml-1 and the second experimental group (n = 6) got culture at the concentration of 3x107. ml-1. Control group (n = 6) got only milk. Blood samples were colected on the 0th, 2th, 5th and 10th day of the experiment. The Bacillus licheniformis significantly increased level of haemoglobin, values of packed cell volume (PCV), number of erytrocytes on day 10 of the trial. Level of total cholesterol in blood of the experimental groups was steady while cholesterol in the control group increased on day 10, which expressed significantly compared with experimental groups. Application of Bacillus licheniformis do not influenced index of phagocytic activity of neutrophils and level of minerals in blood.
