PECULIARITIES OF MICROBIOCENOSES IN LIVESTOCK PREMISES IN THE TYUMEN REGION
For the successful prevention of diseases caused by conditionally pathogenic microflora, it is necessary to know the composition of the microbiocenosis of livestock buildings where animals of different age and physiological groups are kept. The aim of the work was to study the characteristics of microbiocenosis of livestock buildings for various purposes. The study of the composition of the microbiocenosis of livestock buildings was carried out in April 2018 in one of the breeding reproducers of the dairy business of ZapSibHleb-Iset LLC with. Krasnovo, Isetsky district of the Tyumen region. It has been established that the composition of the microflora of the examined livestock houses consisted of six types of microorganisms, three types of bacteria - Staphylococcus aureus, Streptococcus faecalis, Escherichia coli and fungi - Mucor, Candida and Aspergillus. Depending on the purpose of the premises, there were differences in the quantitative indicators of microorganisms. Thus, the total number of colonies of microorganisms on five Petri dishes, selected in the maternity ward and calf houses, where calves are kept from 0 to 6 months, was 903 colonies; in a housing with dairy cows aged two years and older, the total number of colonies was 953 colonies, and in the case of rearing rearing calves aged from 6 to 12 months, the smallest quantitative indicator is 535 colonies. The largest representation in the microbial community was Staphylococcus aureus, subdominant Streptococcus faecalis, and Escherichia coli colonies were found in a small amount. The most common mold fungi were Aspergillus, the maximum total number of colonies grew from the air of the body of the rearing of young stock - 49 and the maternity ward with calf - 32. Fluctuations of the total number of colonies of microorganisms in the air of rooms with different purposes can be explained by various indicators of microclimate, dust and crowded animals.
