INFLUENCE OF ULTRA DISPERSION HUMATO-SAPROPEL SUSPENSION ON BIOCHEMICAL COMPOSITION OF BLOOD OF HEIFERS

The article presents results of studies on usage of ultra-dispersive humate-sapropel suspensionin animal feeding, its effect on biochemical parameters of blood serum, including those which characterize functional state of liver.Moreover, a comparative analysis of introduction of two dosages into the rationwas carried out. The studies were carried out in the conditions of the farm SPK "ImeniIlyicha" in Novgorod region on Holstein heifers selected for insemination. It was establishedthat usage of ultra-dispersive humate-sapropel suspension in combination with the main diet at the doses of 20 ml and 25 ml allowedto increasecreatininecontent by 10.4% and 13.2%, respectively. In the same way, the consumption of ultra-dispersive humate-sapropel suspension affected the concentration of glucose in blood serum of heifers of the experimental groups, increasing it by 30.2% (20 ml) and 9.2% (25 ml). Introduction of the suspension into the rationimprovedbilirubinconcentration, increasing its values in the first experimental group by 39.6% and 14.6% in the second. There is a decrease in De Ritis coefficient by 17% (20 ml of ultra-dispersive humate-sapropel suspension) and 13.3% (25 ml) in the experimental groups; usage of ultra-dispersive humate-sapropel suspension at a dose of 20 ml in the experiment led to a decrease in Gamma HT activity by 14.6%, which allows to make an assumption about the therapeutic efficacy of ultra-dispersive humate-sapropel suspension ashepatoprotector. Thus, on the basis of the experimental data obtained, it is possible to recommend usage of ultra-dispersive humate-sapropel suspension in the rations of young animals in case of violations of liverfunctional state, as well as for preventive purposes at a dose of 20 ml per head per day.
