Abstract
The article describes the problem of microbial contamination of feed in animal husbandry and the microflora that causes mastitis in lactating cows. The microbial contamination of 52 commercial batches of fodder from 5 farms of 3 regions of Ukraine (barley, corn silage, oat haylage, alfalfa hay, sunflower meal) has been determined. Pasteurella multocida in association with Neisseria lactamica, Actinobacillus pleuropneumonia, Clostridium perfringens was isolated from 61.5% of barley, 66.7% of corn silage, 60.0% of alfalfa hay, and 50.0% of sunflower meal. 262 samples of milk from cows with mastitis have been studied. Aspergillus candidus, Aspergillus niger were most often isolated in association with Mycoplasma bovis, Streptococcus agalactiae, Candida albicans, Neisseria sicca, Clostridium perfringens. High film-forming activity of microorganisms in feed was determined, by optical density: Pasteurella multocida + Actinobacillus pleuropneumonia D620 = 3.76 and Pasteurella multocida, Actinobacillus pleuropneumonia, Neisseria lactamica D620 = 3.62. While from the milk of cows with mastitis we isolated associations of microorganisms that were strong producers of biofilms by the optical densities D620 = 4.02 and 4.23
