The features of lipid metabolism in steers of Hereford breed when fed feed protein additive Biovitel

Abstract

The big interest of the feed protein additive Biovitel has been triggered the recipe of which was developed at the Department of feeding, animal hygiene, technology of production and processing of agricultural products of the South Ural State Agrarian University. It has been created on the basis of crushed adipose layer of cattle skin with the addition of micro- and macronutrients, and vitamins. The purpose of the research was to study the lipid metabolism indicators in steers of Hereford breed against the background of the use of the feed protein additive Biovitel. In order to achieve this purpose two groups of steers-analogs of Hereford breed per 10 heads in each at the age of 6 months have been formed. The duration of the experiment was 22 days of the preparatory period and 275 days of the main period. The 1st group of steers have been as a control, the 2nd group of steers have received the feed protein additive Biovitel for 30 days with a 10-day interval. The dose of the feed protein additive for 1 head was 100 g/day – once. The animals have been received the additive at the age of 6 and 12 months. It has been found as the result of the research that the feed protein additive Biovitel affects the body of young animals, increasing the concentration of total lipids and reducing the lipid index by the end of the fattening period of steers of Hereford breed to 0,49, while the control group of steers had the lipid index of 0,52. In this regard, we can recommend this feed protein additive to agricultural enterprises engaged in fattening young cattle.
