Влияние скармливания препарата «Биоплекс™» на продуктивность и содержание микроэлементов во внутренних органах молодняка свиней

The article presents results of scientific and economic experiment on the growing piglets (since 28 days to 4 months) on the feeding of two forms of premixes. Young stock from the control group was fed the standard additive, which contained sulfates of manganese, ferric, copper and zinc, and also sodium selenite. Instead of them the additive BioplexTM was included into the composition of the experimental premix, in which the enumerated elements were in the organic form. Feeding of BioplexTM to young pigs contributed to an increase in av-erage-daily gain, in comparison with control animals, by 7.0 % with simultaneous reduction in the expenditures of fodders by 9.7 %. At that, the coefficients of di-gestibility of dry matter, organic matter, protein, cellulose, nitrogen-free extrac-tive substances in piglets of the experimental group were higher respectively by 2.4, 2.8, 2.2, 2.4, and 2.1 %. The balance of nitrogen, calcium and phosphorus in both groups was positive. A quantity of copper, zinc and ferric in livers, stomachs and small intestines in the animals, that obtained the organic form of microele-ments, was more than in the control, to 4.5, 20.2, 202.0 % and 41.6, 80.7, 25.7 %, respectively, for copper and ferric in the small intestine these values were 69.2 and 97.8 %. The content of copper in the kidneys of the piglets from the experi-mental group was less, in comparison with the individuals, which were fed by the usual additive, 2.4 times, ferric to 46.1 %, and the content of zinc, on the con-trary, was more 2.6 times. The inclusion of BioplexTM into the premixes for grow-ing piglets had a positive effect on the biochemical indices of blood. In comparison with the control, the content of erythrocytes increased by14.8 %, hemoglobin by15.8 %, lymphocytes by 4.34 %, beta globulins by 8.41 %, gamma globulins by 28.7 %, ASAT by 12.9 %, ALAT by 10.5 %, calcium by 41.2 %, phosphorus by 7.7 %, copper 1.9 %, ferric by 8.6 %.
