Abstract

At the present stage of poultry production is characterized by a high technological level of development thanks to purposeful work of breeders, animal feed production technologies and equipment. Use of crosses with high potential of growth and development, so we must encourage such feature by optimizing the diet of biologically active substances or to search for new effective their sources. The article presents data on the positive effects of high doses of vitamins A and E in feed for broiler chickens. In particular, the live weight increased by 8,89 % compared with the control group. Anatomical development carcasses showed that in experimental groups significantly increased breast muscle mass from 11,09 to 37,30%. Along with the growth of the mass of pectoral muscles in broiler chickens research groups reduced the number of internal fat, indicating that the improvement of the quality of meat. Also significantly higher glycogen content in the pectoral muscles.
