The article deals with the results of biochemical and biophysical search of hoof horn of clinically healthy cows and patients with purulent pododermatitis. It is known that the development of the inflammatory process in the area of the hoof, in particular, for purulent inflammation of the producing layer of the skin, affects not only the general condition of the organism of animals, but also the biochemical indices of the hoof horn of the cows. Thus, in the epidermis of cows hoof for purulent pododermatitis, there is a probable increase by 3.7% moisture content and by 26.8% -the concentration of SH-groups in the tendency to reduce the concentration of ash, fat and protein. These changes indicate a slowdown in the keratinization and accumulation process, as a result, in the hoof horn of the epidermis, excessive moisture content. It was found that other biochemical indices influence the state of the hoof horn, in particular, the concentration in the epidermis of the hemispheres of sulfur, keratoses, calcium. Thus, for purulent pododermatitis, the sulfur content decreases by 17.1%, calcium -12.3%, which indicates a deterioration of keratinization processes, which is confirmed by the redistribution of sulfur concentration in keratoses, namely an increase of 2.9% of the contents of a-keratosis and 3.7% was g-keratosis. In the process of keratinization, microelements, in particular copper and zinc, play an important role. For purulent inflammation of the producing layer of the skin of the cows hoof, a decrease in the concentration of these mineral substances is observed on 17.9 and 13.9%, respectively. Changes in the biochemical indices of the epidermis in the cows hoof for purulent pododermatitis also affected its biophysical properties. Thus, the density of the hoof horn was decreased by 7.3%, and the hardness by -2.5%. Consequently, purulent pododermatitis is accompanied by changes in certain biochemical and biophysical parameters of the hoof horn, which reflects the processes occurring in the epidermis of hoof and is one of the triggers of the development of inflammation of the skin of the cows hoof.
Violation of the conditions of animals keeping and the lack of proper level of veterinary and sanitary culture on farms does not allow to achieve a balance between the organism of the cattle and the environment of its stay. The uneven distribution of body weight on the surface of the sole caused by keeping animals on a rough floor promotes the emergence of producing corns, stretching of the tendons and ligaments, slippery flooring leads to the fall of animals and the occurrence of various injuries, in particular, fractures of the limbs, tensile bond, capsule of the joint, excessively hard floor – to excessive erosion of the horn of the sole, etc. In such herds it is difficult to maintain animal health at the proper level and prevent the occurrence of, in particular, aseptic pododermatitis. The article deals with the results on the dissemination of aseptic pododermatitis in cows for the presence of animals on wooden and reinforced concrete slit floors during the winter and standstill period of containment. It has been established that aseptic pododermatitis in cows on reinforced concrete slit floor is registered in 71.6% of cases, while on wooden – only 28.4%. In the hoof horn of the thoracic and pelvic extremities of the cows, with aseptic pododermatitis, the amount of moisture decreased by 8.2 and 9.3% respectively, the concentration of SH-groups increases by 10.6 and 15.8%, with a possible decrease in the content of calcium, sulfur, cuprum and zinc; decreases the hoof horn density and resistance to abrasion of the epithelium of the hooves of the pelvic limbs by 1.6 and 18.0%, as well as the intensity of the abrasion sole hooves of the thoracic and pelvic limbs is increased by 7.5 and 20.0%, which helps to reduce the growth of the epidermis of the sole. Consequently, changes in certain biochemical and biophysical indices of hoof horns of cows suffering from aseptic pododermatitis, which were held on the reinforced concrete slit, indicate a deterioration in the quality of the epidermal hooves and excessive erosion of the sole, which is one of the causes of the occurrence and development of aseptic pododermatitis in cows.
The article deals with the results of researches of many scientists concerning the pathogenesis of purulent pododermatitis in cattle. A considerable distribution of orthopedic diseases, in particular pododermatitis in highly productive cows, has been established. It is proved that untimely corrective cleansing of the hoof, and as a consequence of deformation, prolonged stall content, unsatisfactory zoo-hygienic conditions, in particular, the high content of ammonia in the air, moisture, nymphs on the floor, the imbalance of ration of feeds, the deficit in ration of nutrients and minerals, the absence of the mition and insolation, leads to a deterioration in the quality of the hoof, which is manifested by changes in biochemical and biophysical indices. This leads to aseptic pododermatitis, and penetration into the area of the sole of the microflora and microscopic fungi contributes to the purulent inflammation of the base of the skin of the hoof soles in the livestock. The theoretical substantiation and practical confirmation of the role of microscopic fungi in the pathogenesis of purulent pododermatitis in cattle, which is to destroy hoof keratin, which is due to the keratolytic properties of fungi. It has been scientifically proven that the identification of keratomycetes in the hoof horn is important in the diagnosis of purulent poddlermatitis in animals and influences the choice of directions for their successful treatment. It was established that the elimination of negative conditions of keeping, feeding, corrective cleansing, provision of animals for motion and insolation in combination with the application for therapeutic purposes of substances that possess not only anti-inflammatory, antimicrobial, but also fungicidal properties contributes to the rapid recovery of orthopedic animals.
The article deals the results of searches on the prevalence, etiological factors and pathogenic mechanisms of certain dental diseases in cats. The analysis of literary data of domestic and foreign scientists testifies, that among dental diseases in cats the largest group consists of periodontal diseases. The changed type of feeding, the imbalance of the ration, the lack of complete self-cleaning of the teeth lead to a decrease in the immunobiological reactivity of the organism. Incorrect bite, deformation of the teeth, parodontopathy, etc. cause an animal's discomfort, cause complications in the cardiovascular, respiratory and other systems. Periodontopathies are registered, for the most part, in adult cats. The etiological factors of periodontal diseases are local and general. The starting mechanism of the inflammatory process in the peritoneal tissues is a violation of the ratio of various associations of microorganisms, the balance of which depends on the presence of dental plaque and dental stone. The results of research of many scientists testify that periodontal diseases are accompanied by complicated and profound disorders at the morphological level, as well as systemic changes in metabolic, biochemical, immunological and endocrine reactions. In the absence of prevention, untimely diagnosis of periodontal disease and the treatment of dental sick cats irreversible changes in the dental system of animals are developed. Diseases of the oral cavity in cats is one of the main causes of loss of teeth, the emergence of deformations, the formation of chronic foci beyond the oral cavity and the development of various forms of somatic pathology. Therefore, to prevent the development of periodontal disease and their complications in cats it is necessary to develop effective measures for the prevention of diseases of the parolont, and for stomatologically sick animals - methods of treatment with the use of new medicinal substances.
