Development of a production technology of a national anthelminthic preparation Triclafen (from benzimidazole group) on the basis of triclabendazole and fenbendazole was realized in the conditions of the Republic of Belarus. As a result of realized experiments it was found that the developed suspension corresponded the requirements of pharmacopoeial items and can be applied for veterinary practice. Composition of different components with wide action spectrum made it possible to apply it against ruminant animals.

This article is devoted to a problem of biochemical interaction of selenium and antioxidational system of animals and people organism. The problem we have touched is about the efficiency of influence of organic and inorganic taking place on subcellular level. The advantages of organic selenium are proved, the degree of its bjochemical influence on an antioxidationi status of health are indicated.

Analysis of national studies and literary sources on problems of haemophilus pleuropneumoniae of swine was realized in the conditions of the republic of Belarus. Research was realized in the conditions of Agricultural Production Co-operative Uritskoe (Gomel region, Belarus). It was established that medical actions gave positive result only at early stages of disease.

A method of development of highly purified antigen of a virus of classical swine fever (Sinlak strain) for definition of antibodies in enzyme multiplied immunoassay (ELISA) was tested in the conditions of the Republic of Belarus. There were determined parameters of sensitivity and specificity. There was developed a method of partial purification of the antigens by means of obtaining of infected leukoconcentrate, settling of virus by means of ammonium sulfate with the further ultrafiltration through a membrane

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.

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.

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

The given research results of feeding highly productive cows with new forage supplement of humic-melanoidine nature during the milking period show stable mineral metabolism, correction of their redundant supply within the diet, perfection of digestion and transition into milk as well as minimizing consequences of metabolism intensification. Reception new forage supplement promoted improvement of mastering by an animals organism of necessary iron during the given physiological period, to restriction of mastering of the microelements equal to the category of heavy metals
