Evaluation of efficiency of chelate forms of trace elements in rations of pregnant sows as a factor of improvement of their production indices and quality of obtained litter. It was determined that introduction into pregnant sows rations of chelate forms of zinc and iron starting from the 84th day of pregnancy and till farrowing led to authentic increasing of milk yield, weight of a litter at birth and at weaning periods, to increasing of live weight of obtained litter, and also proved to be a form of hypothrophics prevention in piglets.

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

In the conditions of the Republic of Belarus after fasciolosis invasion of cattle for the biochemical diagnostics of liver pathologies there was composed a hepatospecific metabolic profile of blood serum of cattle into which there were included several enzymes (alanine aminotransferase; aspartate aminotransferase; gamma-glutamyl transpeptidase; alkaline phosphatase; and cholinesterase), content of total albumin, serum albumin, total cholesterin and total bilirubin, as well as colloid tests (thymol turbidity test and test for apoliproteins). There was revealed a intrahepatic cholestasis developed during fasciolosis infestation, as well as dysproteinemia as a compensatory mechanism of liver proteinsyntetic function.

The analysis of data on a complex of reproductive qualities crossing sows has shown, that the combinations used in the classical scheme of variable crossing have appeared are less effective in comparison with the combinations including foreign meat breeds. It is recommended to change the traditional scheme of variable crossing, having excluded from it the Belarus black-motley breed and having entered foreign breeds of L and D and also to use hybrid male pigs (D x P)

Results of the scientifically-economic experience lead in farm Zarechje (Smolevichskij district of the Minsk area) have shown, that perfect metabolizable energy concentration in dry matter of a diet at milking period for first-calve cows is 11,7 MJ/kg. It allows to increase natural milk productivity at 8,24% (27,4 against 25,4 kg) and 4%-milk outcome – at 8,93% as well as effective usage of metabolizable energy for production up to 4,9% (P less than 0,01) and minimum of production warmth loses

In the article showed results of the researches of the influence on productive longevity of cows of such factors, as a linear belonging, a genotype of the father, type of selection are stated. The lead researches have shown, that more longer duration of use characterized the animals belonging to line Siling Trajdzhun Rockit 252803 - 4,5 lactations. Among daughters of various bulls the greatest term of productive use daughters of the bulls the Silach 158 - 5,0 lactations differed. At the maximal deviation in efficiency of ancestors (6001-7000 kg of milk) longevity of their daughters was the greatest and has made 4,18 lactations. The greatest influence on duration of economic use of cows was rendered by specific features of bulls (32,2%) and a linear accessory -12,0%. While the selection variant practically does not influence longevity of animals - a share of influence of 3,7%

In the experiment with swine there was studied the influence of ultra-violet and various doses of narrow-band red radiation on efficiency and safety of animals. It has been established, that efficiency and safety of animal skilled groups in comparison with animals of control group has risen. Use of an ultra-violet and narrow-band red irradiation with frequency rate of inclusion of red light three times has a day allowed to raise average alive mass of young plants of pigs on 2,5 kg or on 9,1% (Р less than 0,01), a daily average gain - on 9,6%(Р less than 0,001) and safety of animals - on 10%
