Barashkin M.I., Petrova O.G.
Summary. Data on the analysis of the results of observations in farms of Ural region are presented in the article. Milk yield of cows significantly increased over the past 7 years in the farms of the Sverdlovsk region in industrial technology, content. This is due to the increase in the proportion of the diet of feed. Many farms specialists recorded deterioration of animal health: reducing rumen pH, of acid base balance of blood, metabolism, reproductive function. All this leads to shorter lactation, early retirement from a herd of cows. Studies conducted by regional, zonal district, laboratories of Sverdlovsk region, pointed out that the retired high producing cows most often recorded by the affected limb (22.3-25.6%), metabolic disorders (24-24.9%), diseases of the reproduction (9.7-14.5%), digestive (15-16.5%), mastitis (9.5%), infectious pathology (19.5%). To increase the efficiency of milk production at industrial technologies knowledge of the content of rumen digestion, which will generate an overall plan for the production of fodder on the farm with the main characteristics - nutrient status, exchange of energy, moisture, acidity is needed.
Key words: Sverdlovsk region, cattle, dairy farming, rumen acidosis, laminitis, lameness, mastitis, infectious diseases, blood serum, metabolism.
