Course description

Animal Hygiene is the branch of the veterinary science, which relying on the knowledge of physiological and ethological demands of animals, describes the preconditions of health preservation and investigates the pathophysiological changes brought about by adverse environmental effects in order to gain information on the aetiology and pathomechanism of multifactorial diseases. On this basis, animal hygiene systematise the preventive veterinary measures with special reference to their economic consequences. Animal hygiene deals primarily with herds and health protection of the herds, therefore the subject is more or less equivalent to the subject „herd health ” taught in number of the veterinary colleges of the western hemisphere.

Animal hygiene is an interdisciplinary science that lays bridge over animal husbandry and veterinary medicine. Its curriculum involves the management and nutrition technologies of farm animals. The discipline also describes the multilateral effects of housing and nutrition on the health, on the inherited behavioural characteristics of farm and companion animals, on economy of their production and on the rural environment. Based on these knowledge vet­erinary undergraduates will be trained to become able for critical analysis of housing systems and nutritional regimes, for understanding the aetiology of management related diseases prevailing at herd level, for the application of methods of herd health management in order to prevent and control of multi­factorial diseases of high economic consequences.

Beyond teaching theoretical and practical knowledge of the discipline we endeavour to implement three goals. First of all we try to form an approach by which the veterinary practitioner becomes able to analyse the production decline, abnormal behaviour and animal diseases in their complex interactions with the environment. We also intend to prepare our undergraduates for the analysis of the economic consequences of their preventive and curative meas­ures. And last but not least in harmony with other disciplines we regard important to teach our students to esteem and acknowledge the work of experts of other branch of agricultural science.

Theoretical and practical knowledge of animal hygiene is based on animal physiology, husbandry, nutrition, microbiology and immunology. At the same time it contributes to the better understanding of epizootology, state vet­erinary medicine and food inspection.
