BIOCHEMICAL INDICATORS OF BLOOD SERUM IN COWS VACCINED BY ASSOCIATED VACCINES AGAINST VIRAL-BACTERIA ENTERITIS IN CALVES
The article presents the results of biochemical studies of blood serum in cows after vaccination of animals experimental samples associated vaccines against infection enteritis of calves. The use of test vaccines does not cause changes in the biochemical parameters of blood in vaccinated cows, both in relation to the control group and in comparison with accepted reference values, which indicates the harmlessness of the developed associated vaccines in animals.
