UNFAVORABLE MICROCLIMATE PARAMETERS AS FACTORS CONTRIBUTING TO THE DEVELOPMENT OF FOOT DISEASES IN COWS

The results of clinical and orthopedic examination of Holstein cattle in free-range conditions are reflected in the article. Lameness in animals of varying severity 25%, deformation of the hoof horn 20%, interdigital dermatitis 10-15%, laminitis 15-20%, purulent-necrotic lesions of the hooves 15-20% were established by us. The revealed pathologies of the distal extremities were the result of violations of the zoohygienic parameters of the microclimate and the technology of keeping highly productive cows. The microflora Enterococcus faecium, Escherichia coli (non-pathogenic type), Staphylococcus aureus, Proteus spp., fungi (Aspergillus spp., Mucor spp.) was isolated during microbiological studies of scrapings from the wound surface of the hooves. Molds Aspergillus spp., Mucor spp., Fusarium spp. revealed in samples of bedding material (straw) from animal resting places, which contributes to the development of diseases of the distal extremities of an infectious and non-infectious nature.
