Abstract

From the standpoint of modern ideas, the normal functioning of the poultry body and full implementation her of the genetic potential is impossible without the presence of selenium in the diet. The biochemical diversity of selenium puts it in a number of priority trace elements. Scientists who were studying the effects of selenium on poultry body and paid relatively little attention to the quality of the meat. In scientific experiment are studied the effect of additives different doses of selenium in compound feed on the chemical composition, energy and biological value of meat of the cross chickens-broilers COBB 500. Introduction of selenium into the feed for broiler chickens in the doses which are studied (0.3 mg/kg, 0.4 and 0.5 mg/kg) did not significantly affect to the quality of their muscle tissue although it positively affected on some indicators that characterizing its chemical composition, nutritional and biological value. Among the experimental groups, the best meat quality indicators were in the second group of chickens for which was introduced into the feed selenium from the calculation of 0.3 mg/kg. When feeding mixed feeds with selenium additives to broiler chickens it was found that it is likely to increase the concentration of this trace element in muscle tissue by 60.6-100% (P?0.001), which does not exceed the maximum permissible level (MPL). Consumption of selenium-enriched meat of broiler chickens within the limits of the physiological norms recommended in Ukraine will ensure the daily requirement of an adult in this trace element by 23.6-29.4%. This meat product can be especially useful for people who live in regions with low levels of selenium in the natural environment.

Highlights

Among the numerous elements of the technological process of growing young poultry for meat which ensure its high productivity and viability as well as the proper payment of feed with high-quality products and important role is given to full-fledged feeding
Ukrainian Journal of Ecology, 9(4), 2019 tissue samples showed that broiler chickens of the experimental groups generally had slightly better chemical indicators of meat quality and some indicators were at the level of the control group
Despite the absence of a significant difference between the groups for most indicators that characterized the nutritional value of meat, the nature of the deposition of protein, fat and ash in the muscle tissue of young animals of the experimental groups in a certain way indicates the influence of selenium supplements

Summary

Introduction

Among the numerous elements of the technological process of growing young poultry for meat which ensure its high productivity and viability as well as the proper payment of feed with high-quality products and important role is given to full-fledged feeding. Selenium is contained in the body in small quantities performs unique multifaceted functions such as catalytic, structural, regulatory in the process of which it activates the action of many enzymes, vitamins, hormones and ensure the normal functioning of various biological systems the implementation of numerous physiological and biochemical reactions in a living organism (Reilly, 2013). From the standpoint of modern ideas the normal functioning of the poultry's body and its full implementation of the genetic potential impossible without the presence of selenium in the diet. This is due to the inconsistency of differentiated norms of its introduction into feed for poultry of different species, age and direction of productivity. The same opinion is shared by their colleagues from Germany
