The spread of respiratory disease in cattle and caused economic damage
O. G. Petrova, doktor veterinarnyh nauk, professor, A. D. Alekseev, aspirant Uralskogo gosudarstvennogo agrarnogo universitetaCattle breeding- is the leading branch of agriculture. The basis of the livestock is cattle, which is a provider of valuable food for mankind: meat and milk. The value of meat is determined by the nutritional content of protein and fat. Milk contains all biologically active substances, many of which do not exist anymore in any other product. The quality of milk and meat directly depends on the state of health of animals.
The ongoing economic reforms in the country changed the situation in animal husbandry. The diversity of forms of ownership led to a change of veterinary service and technological processes in the industry. At the present stage in front of a veterinary science and practice arose the problem of diagnostics, prevention and treatment considering the new conditions. In addition, market conditions formed numerous intermediary and trading subjects, trade of animals and derived products from them expanded. Modern farming has entered a qualitatively new stage of development. Currently industrial methods of livestock are widespread: modern facilities are building, old ones are modernized, computer technologies are widely used.
All these facts led to changes in the epidemic situation and manifestations and course of animal infectious diseases. Respiratory diseases of infectious etiologies are most common and are one of the leading causes of death. They remain the only form of pathology, the death from which not only has not decreased, but continues to grow. According to the forecasts of veterinary experts, by 2020 respiratory diseases will be included in the top three indicators death. Economic losses associated with diseases of respiratory tract of animals carry to economy huge harm.
Another side of the problem is delayed diagnosis. Outbreaks of respiratory tract of infectious etiology they are detected in more than 20–25 % of cases. Important is the question of the problem of the control of communicable diseases of respiratory organs – the lack of comprehensive information about the peculiarities of their epizootology.
