Biochemical parameters of blood of calves when using a probiotic based on the strain enterococcus faecium l-3

Abstract

In this paper, we studied the effect of a probiotic, based on the Enterococcus Faecium L-3 strain on 20 black-motley calves. The effect of the drug on their biochemical parameters of blood serum were studied. The authors found that this drug, which was fed to calves up to 45 days of age, had a positive effect on the biochemical parameters of blood and on the total animal organism.. So, at 14 days of age, blood serum parameters in calves, not receiving the drug, such as: bilirubin, alkaline phosphatase, alanine aminotransferase and aspartate aminotransferase levels were significantly higher than in calves that received probiotic, which indicates possible dystrophic changes in the liver. Also, at 14 days of age in cows, recieving the drug , the blood serum amylase level was significantly higher than of the calves, not receiving the drug. By the age of 30 days, the tendency to a higher content of bilirubin, alkaline phosphatase, alanine aminotransferase and aspartate aminotransferase in the blood serum, persisted in the calves of the control group, compared with the animals of the experimental group. By the age of 45 days, the levels of bilirubin, alanine aminotransferase and alkaline phosphatase were also significantly higher in control group of animals, than in experimental group and were 5.0 ± 0.56 pmol / L and 3.72 ± 0.4 pmol / L , 30.66 ± 2.9 IU / L and 16.52 ± 1.2 IU / L, 345.7 ± 30.7 and 226.6 ± 24.1, respectively.The results obtained, indicated that regular feeding of a probiotic based on Enterococcus Faecium L-3 to calves of the milky period, contributes to the normalization of biochemical parameters and greater resistance to gastrointestinal disorders.
