INFLUENCE "STRAFIT" AND ITS DERIVED ADDITIVES ON WHITE RATS GROWTH RATE AND IMMUNE PARAMETERS
The aim of our study was to investigate the effect of «Extrafit» feed additives and its derivatives produced from amaranth on the intensity of white rats growth and immunobiollogical blood parameters. The flavonoids isolated from amaranth leaves were represented by 87% of rutin and 13% hyperoside. The experimental rats feeding containing «Extrafit» in the dose of 2.0% per dry fodder and biologically active additives (flavonoids, residual fraction and squalene) in 2% per body weight, ratio increased the animals’ growth rate. Moreover, the greatest difference between the absolute and average daily gain in live weight of white rats from control and experimental groups was registered at the beginning of the experiment. The blood sera immunological studies showed that using “Extrafit” drug, flavonoid, its residual fractions, and squalene significantly increases bactericidal (4.8-12.1%), phagocytic (3.4-11.9%) and lysozime (12.9-41.6%) activity of blood serum, phagocytic number (up to 14.9%) and phagocytic index (3.5%), promotes animal nonspecific response and resistance to environmental negative factors.
