The article presents an analysis the literature data on the frequency of and etiologic factors of disease of cows hooves, including different clinical forms of pododermatitis. It is established that the deterioration of the quality hoof horn, which causes diseases of hooves influencing on poor conditions of keeping, unbalanced feeding, by deficiency of nutrients and minerals, deformation hooves, lack of motions, insolation and corrective clearing. An important place in the pathology of highly productive cows hooves strains belonging to deformations of hooves horn. It was established that determining influence on the formation of deformed hooves have errors in feeding (excessive feeding of concentrated feed - for high concentrate feeding), in keeping (absence or lack of active constitutional, the use of concrete, brick and slot floors, etc.) and breeding of animals with deformed hooves, irregular shape of which are inherited. To orthopedic diseases include diseases: pod dermatitis, laminitis, ulcers of pulp (Rusterholts ulcer), body, and also purulent necrotic lesion, which mostly occur in the form of rim phlegmon and pulp, caused by an infiltration of pathogenic microflora through damaged skin, rarer due to metastasis of infect. However, despite the significant number of works, devoted to the problem of orthopedic pathology, remained undefined a number of issues regarding pathogenesis of some clinical forms of pododermatitis, in connection with that in Ukraine research in this direction were conducted. So perspective is depth study of some links of pathogenesis, some clinical forms of pododermatitis to develop tactics and treatment method of orthopedic sick 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.

According to the analysis of literary data it was found that in veterinary dentistry orthodontic disease are common, among which are abnormalities of the teeth and dental bite. The causes of the anomalies of the teeth- jaw apparatus are congenital and acquired. These include hereditary, genetic abnormalities, insufficient development of chewing muscles, insufficient root resorbtion of deciduous teeth, reducing the size of the jaws and gums for virtually no altered the shape of the teeth, errors in diet (soft and liquid feed, calcium deficiency), developmental disability, training with the wrong load on the teeth of young animals, deficiency of minerals in the diet, late change of teeth, tooth size discrepancy to jaws sizes, too large molars and so on. Hyperdontia, olihodontia, convergence, retention are registered among anomalies of the teeth. Violation of the number of teeth, the formation and eruption of teeth are referred to the abnormalities of teeth. Violation of the formation of teeth consists of enamel and dentine dysplasia. To the violation of the teething belong: retention, false polilentia, primary or secondary wolf mouth, dysplasia of temporomandibular joints, cranio-mandibular osteopathy (QS). Furthermore we pay attention to the displacement of the tooth crown and crown slope of (retroposition, vestposition, torpoposition, supraposition, infraposition, mezioposition). To the malocclusion in dogs belong: прогнатию, прогенію, direct bite (central occlusion), anterior cross bite, crooked bite, the open bite, alveolar bite, floating (not constant), skewed bite, mixed bite. Malocclusion of teeth and other problems could cause injury to soft tissue, cause pain and to promote the emergence and development of severe periodontal disease.

Out of all diseases of organs and systems of teeth disease in dogs is a group of diseases, the symptoms of which are most often observed only when the process involves not only teeth, but also the tissues surrounding them. Paronodopathies deserve special attention, among which chronic catarrhal gingivitis is a polietiological disease in which pathogenesis has a major role in the microorganisms of the oral cavity of dogs, odontogenic deposits in the form of plaque and dental stone. The disease can be complicated by loss of teeth, deformation, reduced functionality of the tooth-jaw system, the formation of chronic diseases in the body, sensitization and development of various forms of somavtic pathology. It has been established that among surgical diseases of dogs gingivitis is most often detected, which is 31.7%. Among the various forms of gingivitis, the largest percentage is the chronic catarrhal gingivitis, which is registered in 47.5% of dogs, mostly dwarf breed. Somewhat less, namely 20.3%, is acute catarrhal gingivitis, 11.9% is chronic hypertrophic and 8.5% is chronic ulcerative gingivitis. The disease is appeared by galitis, disturbance in the intake of food, edema, bleeding of the gums, lesions of the clear papillae, dental plaque with anthrax, formation of pseudocysts. For the objectivity of disease information, clinical manifestations are presented in the form of numerical expressions and dental indexes. It has been established that chronic catarrhal gingivitis in dogs is characterized by an increase in the number of microorganisms in the biotope of the oral cavity, which contribute to the development of inflammation in the gums.
