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.

Development of a new national preparation for the preventive maintenance of cow mastitis, fissures of milking tubes skin of cow udder was realized in the conditions of the Republic of Belarus. The preparation Maz' Solnechnaya ("Unguent Solnechnaya") did not contain antibiotics, hormones and other synthetic components. Natural components of a preparation provide long anti-inflammatory action, stimulate local blood circulation, regeneration of epidermis and accelerate processes of healing of microtraumas. Besides it possesses high efficiency at preventive maintenance of mastitises at cows.

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

In article results of studying of efficiency and quality of poultry-fanning production under influence chitosan are considered. It is established that the preparation promotes safety increase on 0,5%, efficiency on 6% and biological value of meat on 20% at chickens whom gave to drink chitosan in a dose of 5 mg/goal from 32 day age it) comparison with the control. Such technological reception leads to decrease the receipt in an organism of a chicken of microtoxins, heavy metals, products of a metabolism of bacteria

Results of researches on studying influence separate and combination feeding fermented compositions Fekord-2004C and biologically active additive Oxide Peat on energy of growth and protective properties of an organism of pigs – deprivation are stated. It is established that enrichment of mixed fodder investigated by the fodder fermented additive Fekord-2004C at the rate of 0,15 kg on ton of mixed fodder in combination application with biologically active substance Oxide Peat in a doze of 1,0 kg on ton of mixed fodder promotes increase of growth rate of pigs on development and to decrease of the charge of forages on unit of a gain of alive weight and safety of pigs

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

While studying biochemical values that characterize rumen digestibility based on research agricultural experiment some results were obtained. These results prove that studied diets with increase of energy and raw protein concentration levels in dry matter influence positively at nitrous substances concentration activate micro flora motions and promote bio-synthetic processes in rumen fluid of experimental animals

Increase of diets nutrition energy in our experiment showed no significant effect on usage of nitrogen in feeds. Diets with different energy levels have no negative effect on hematological indices of animals

Results of researches on studying of efficiency and quality of structure of long-term leguminous-cereal coenoses are presented. Productivity of green weight of a multicomponent mix on the average for five years' use has made 336,0 c/hectares. Economic efficiency of a laying and use multicomponent grass mixture is calculated. At use of a multicomponent mix within five years industrial expenses pay off within 1 year

The study has stated that heifer replacements, from the date of birth to 18 months, got through transplantation of frozen-defrosted embryos were not inferior to and in many cases superior to the heifers of their age but got through traditional reproduction. Transplant first-calf heifers have a high level of milk productivity which amounts to 7536,10 kilos, with 3,62% of fat and 3,23% of protein. Thus they provide a good selection material for new generation champions to be chosen among them and for being used as mothers of bulls for service
