It is determined on the basis of conducted researches on perfection of energy-protein nutrition norm of young cattle of 6-12 months of age that 11,5 MJ of exchange energy at 6-7 months of age and decease to 10 MJ for 12 month of age is needed in 1 kg of dry matter to get 1000 g of average daily weight gain. 8-9 g of digestible, 5 g of non-digestible protein should come for 1 MJ of exchange energy of a diet. 1 kg of DM (Dry Matter) should contain 133-150 g of crude and 46-54 g of non-digestible protein

Perfect norms of floor area and feeding front are determined for replacement heifers on free stall management. These norms promote creation of more comfortable conditions of management, increase of average daily live weight gains at 9,1%, hemoglobin content – at 4,8%, erythrocyte quantity – at 6,3%

Treatment of legumes and cereals on hydrodynamic machine TEK-CM allows to obtain tine-dispersed feed products (paste, milk) containing dry matter of 42-30% with better nutrition values compared to initial raw material. Preparation of grain to feeding on hydrodynamic machine TEK-CM increases the sugars contents on 26-56%, free amino acids - on 22-57%, and the quantity of cellular tissue decreases. Activity of the antinutrients containing in a soya, decreases up to a safe level

Increase of protein and energy nutrition norm of dry cows in winter and summer periods at 10 and 15% by protein and vitamin mineral additive based on peas and rape promotes increase of average daily weigh gain at 5,4-12,2%, calves live weight at birth – at 3,6-8,1%, average daily weigh gain – at 3,9 and 12,1%. Optimization of energy and protein content in diets allows to increase milk yield at 5,1-9,9% and decrease forage spends per 1 unit of product at 4,6-9,1%

The use of subcutaneous progesterone-releasing devices in superovulatory treatment allow to get high results of embryo production per donor, viability and pregnancy rates after embryo transfer in cattle. Application progesterone hypodermic inserts has allowed to lower the cost price of one received embryo on 28461 rubles

As a result of the conducted researches it was determined that replacement of milk in diets for suckling calves with whole milk substitute Komnilakt-50/2101 allows to significantly reduce the price and increase profitability of pedigree heifers growing that corresponds demands of the standard of classification for young cattle of 3 months of age on live weight of 90-105 kg at planned live weight of cows of 500-600 kg

In given article natural resistance of geese during the spring-and-summer period is considered at inclusion in a diet coenzyme B12. Namely, dynamics bactericidal, lysozyme activity of blood of geese, dynamics of phagocytosis activity, the general fiber in blood whey, dynamics of fiber gamma-globuline fraction and reliability of distinction between groups is resulted

Efficiency of level increase of colostrums' full value and natural resistance of calves at the expense of application additive stimulating immunity a preparation «Erakond» is proved in the article. Optimum doses and ways of application of a preparation are established

On the basis of the data analysis of morphological and biochemical blood traits it was determined that blood indices of all groups of pigs didn't break the limits of physiological norms. Pigs of Canadian selection differ by high metabolism intensity and immunity of organism

Investigation of method of gastroenteritis treatment of stores by means of application of enterosorbents was realized in the conditions of the Republic of Belarus. For the experiment there was used preparation Lactofiltrum containing 80% of hydrolyzed lignin and 20% of lactulose applied in dose of 0,3 g/kg once a day during 7 days. Efficiency of application of Lactofiltrum was compared with enterosorbent SV-2, which contained alcaline hydrolyzed lignin applied in dose of 1 g/kg once a day during 7 days. Four experimental groups piglets sick with gastroenteritis in the age of 1,5-2 months, with body weight of 15-17 kg were used in the experiment. The first group piglets were entered 0,3 g/kg body mass of Lactofiltrum once a day during 7 days. The second group piglets were entered enterosorbent SV-2 in dose of 1 g/kg in course of 7 days. For the piglets of the third group there was applied the complex of analysed preparations in same course of treatment. The fourth group of piglets was entered enrotim 10% in dose of 1 ml/ 20 kg of body mass. All animals had the same conditions of feeding and keeping. Research results showed that application of Lactofiltrum, SV-2 and their complex provided high antioxidative, detoxification, gepathoprotective activities. These preparations proved to be effective means of pathogenetic therapy for the treatment of gastroenteritis of piglets, both as individual preparations, and complex application. Comparative estimation of treatment methods of gastroenteritis showed that these preparations (except enrotim 10%) made it possible to regulate the metabolic processes due to elimination of intoxication, positive influence on hematopoiesis. The preparations lowered the duration of clinic manifestation of a disease and facilitated its duration, had gepathoprotective and antioxidative activity
