For the determination of efficiency of a new produced in the Republic of Belarus preparation Ehkvikar there was modeled a test with a diaphoresis of guinea pigs by means of their staying in a thermostat at a temperature of 45-50 deg C in course of 30 minutes. Before and after the test there was taken a blood test for its analysis. Results of the experiment showed that together with sudo the animals lost 1-2 % of their body. There was stated the increasing of all blood corpuscles as well as lowering in 1,3-1,47 times of such elements as chlorine, sodium, potassium, and also T lymphocytes and bursa-derived lymphocytes. Application Ehkvikar promoted the stabilization of biochemical and morphological parameters of blood, and also the immune status of laboratory animals. Thus, Ehkvikar preparation promoted the compensation of losses of electrolytes with sudor of guinea pigs and in future can be studied by an example of horses for completion of electrolytes losses in the conditions of increased physical exercises.

Results of chemical and toxicological estimation of an energized preparation, intended for increasing of performance ability and sports qualities of horses realized in the conditions of the Republic of Belarus were presented. The energized preparation included honey, lactalbumin hydrolyzate, pollen hydrolyzate, and teotropin. Chemical and toxicological estimation of the preparation included determination of physical, chemical and pharmacological compatibility of components of the preparation, acute and chronic toxicological characteristics, skin-resorbtive poison after single and long-term application at horse skin, topical-product-induced irritation and allergic action of the preparation. Research results showed that all components of the preparation were compatible among themselves. The preparation proved to be a low-hazardous substance (substance hazard category 4) and did not possess skin-absorptive, local-irritating and allergic action.

In the conditions of the Republic of Belarus there was made a hepatospecific metabolic profile of cattle blood serum for complex appraisal of liver functional condition. Age-specific peculiarities of biochemical indices including the composition of hepatospecific metabolic profile of cattle blood serum were revealed. On the basis of obtained results there were calculated the appropriate correction coefficients which must be taken into consideration in objective interpretation of laboratory research.

The analysis of swine farming production in CHUP Zopak-Agro has shown, that the decrease in the expense of forages and expenses on a payment on made production and increase of productive and breeding qualities of animals by purposeful selective-breeding work promote decrease in the cost price of a gain of live weight of pigs at the enterprise by 55,7 thousand rbl./с (or on 15,3%)

The recipe of mixed fodder is developed for cows with a 6-8 thousand kg yield of milk for a lactation during the period yield of milk, different the raised maintenance of a crude protein (18%) that allows to increase a yield of milk of animals by 6,6% (22,5 kg instead of 21,1 kg of 4% milk a day) to reduce the expense of forages on production unit to 6,4% (0,73 fodder units against 0,78 fodder units per 1 kg of milk). At the expense of additional production economic benefit makes 104,4 thousand rbl. counting on 1 head

The researches were carried out in 2005-2006 at swine complex Zazerye of Mozyr region (the Republic of Belarus), that counts 54 thousand heads annually. The aim of the research is to develop perfect ventilation systems in reconstructed buildings for farrow and weanlings growing, that will provide resource saving and comfort conditions for animals. It is determined that providing perfect microclimate in buildings and energy spends cut for this climate creation in winter period is possible if technological qualities of fence constructions is higher from 0,97 to 2,5 m2 and natural ventilation is used. Microbe semination of the buildings for farrow and weanlings growing at this periods is 1,4-3,6 times lower. During the summer the combination usage of natural and imitation air ventilation is necessary

Use desirable alleles allows to raise the reproductive quality of the sows, in particular, amount alive piglets at birth (EPORTT), safety piglets (MUC4CC) meat quality pig (IGF-2QQ) that in turn allows to get the additional income at realization of the saplings

Results of researches are stated according to efficiency of various ways warmed pigs. It is established, that application of warmed panels allows forming more comprehensible conditions of rest for pigs. Thus within 31 days at 137,13 kw – hour or the charge of the electric power on heating of one jack of pigs is reduced to 68,48% in comparison with use of lamps of infra-red radiation without essential decrease of growth rate and safety of young growth

It is determined that diets with protein digestibility of 61-66% in organism of a calve activate fermentative processes in rumen, increase digestibility of nutrients at 3,8-10,1% that allows to obtain the average weigh gains of 1036-1075 g, that is at 4,2-8,1% higher than that of control group at forage spends of 6,79-7,04 forage units

The research in RUP Scientific and Practical Center of Animal Breeding of National Academy of Sciences on such parameters as consumption of forages, processes of rumen digestion, morphological and biochemical structure of blood has shown that usage of wet grain preserved with Kormoplus for young cattle fattening has a positive effect on physiological condition and digestibility of nutrients and promotes nitrogen usage by animals that increases at 7,0 and 1,6%
