Summary. The paper presents the results on the species and percentage composition of the microflora in biofilms of pig feed, which varies depending on the seasonal factor. Bacteria Streptococcus spp., Pasteurella multocida, Neisseria spp., and Clostridium perfringens in biofilms were found much more often (by 25% or more) in the warm period of the year, while listeria in silage and haylage — in the autumn–winter period. This property of feed biofilms is also significantly influenced by the conditions of cultivation, harvesting and storage of agricultural products. In the study of biofilms of microflora of barley, corn and wheat, it was found that their structural basis are aerobic fungi of the mold Aspergillus spp. Bacteria Streptococcus spp., Pasteurella multocida, Neisseria spp., and Clostridium perfringens without mold form much looser biofilms in vitro and these biofilms are much more sensitive to a wide range of commercial antibiotics. The structural basis of polymicrobial biofilms of barley, corn and wheat microflora is highly likely to be aerobic fungi of Aspergillus spp.
