The correlation of productive and hematological parameters in steers on the background of the use of feed protein additive Biovitel

Abstract

Among the environmental factors, feeding is the most important in the formation of new traits and properties. The level of feeding influences first of all on the digestive system. Then the nature of feeding affects the organs associated with the utilization of nutrients, and ultimately the body as a whole. The purpose of the researches was to study the correlation between productive and hematological parameters in steers against the background of the use of the feed additive Biovitel. The research has been carried out under the environments of JSC “SHF Dubrovsky” in the Chelyabinsk region on steers of Hereford breed. In order to carry out experiments 2 groups of steers (control and experimental) have been formed with 10 heads in each. The method of pair-analogues has been used taking into account the genotype, age, birth weight and physiological state of animals. The experiment has been conducted from 6- to 15-month-old steers. The control group has been received the main farm ration. The experimental group has been received the basic ration and additional feed additive Biovitel at the rate of 100 g/head/ day for 15 days. The correlation between hematological parameters and productivity of steers against the background of the use of the feed additive Biovitel has been determined. During the study a positive correlation between the total protein and protein fractions with the live weight of steers has been observed. High correlation coefficients have been obtained in steers of both groups at the age of 9 months. The amount of total lipids in all age periods in both groups changed relatively little, but the trend of their increase in steers of the experimental group remained. The concentration of phospholipids in the control group was almost at the same level, and in the experimental group there was an excess of control values by 5,52 %. Activation of redox processes in the animal body has been observed under the action of the feed protein additive Biovitel.
