EFFICIENCY OF CLEANING AND DISINFECTION METHODS PREVENTION FOR CALFS

Abstract

The article presents the results of studies on the use of mechanical, physical
and chemical methods of cleaning and disinfection of a dispensary for calves. The
studies were carried out on a farm in the Akmola region of Northern Kazakhstan,
in a calf barn. Cleaning of the dispensary for calves was carried out in three ways:
mechanical method - cleaning with shovels, scrapers, brooms, as well as with the
help of hydro-cleaning; physical method - natural (sun rays) and artificial light
sources - ultraviolet rays of germicidal lamps; chemical method - whitewashing
surfaces and spraying the aerosol preparation GAN-10%. An analysis of the
growth of microorganisms in the livestock premises was carried out according to
the zoohygienic method for analyzing samples of environmental objects. Studies
before treatment of the calf quarters showed a massive growth of bacilli and
bacteria - 100%, molds - 80%, yeasts - 20%, actinomycetes - 80%. After treatment,
the number of microorganisms during mechanical treatment, microbial
contamination decreased by only 31.1 ± 3.5%, with physical treatment already by
56.9 ± 2.8%, with chemical treatment by 91.0 ± 0.6%.
