MORPHOLOGICAL AND BIOCHEMICAL COMPOSITION OF KAZAKH WHITE BREED HEIFERS BLOOD WITH USE OF THE FEED ADDITIVE BIODARIN
The research objective is improvement of the productive qualities of Kazakh white breed heifers by introducing in addition to the basic diet of different doses of feed additives BioDarin. Currently raising meats-term productivity of livestock through a full feeding is promising direction. One way of addressing this issue is the use in the diet of animals. One of the promising supplements is BioDarin. Scientific and economic experiment was carried out on the basis of JSC AIC «Alga+» Tuimazinsk district of the Republic of Bashkortostan. For the experiment there were formed 4 groups of heifers of Kazakh white breed: group I – control; group II heifers in addition to the basic diet received a feed additive in a dose of 0.5 kg per 100 kg of grain mixture, the animals of group III received 1 kg of the feed additive per 100 kg of grain mixture, peers IV groups received 1.5 kg of a grain mixture. Among the studied groups, heifers of the III experienced group receiving feed additive at a dose of 1.0 kg per 100 kg of grain mixture, had better hematological indices. In the course of the research established that the highest levels of productivity and better metabolism differed heifers, which were included in the diet a food additive BioDarin.
