PROSPECTS OF SELENOCYSTINE UTILIZATION IN PRODUCTION OF COTURNIX COTURNIX JAPONICA MEAT AND EGGS FORTIFIED WITH SELENIUM ^{[№ 10 ' 2016]}
Poultry meat and eggs enriched with selenium are widely used all over the world for improving food quality and chicken health. Effect of selenocystine utilization on the quality of quail muscles, organs and eggs is investigated using selenocystine additives in feed of birds (0.15 and 0.30 g Se/t). Selenium supplementation was shown to elevate significantly selenium content in eggs, muscles and liver. Consumption of five quail eggs fortified with selenocystine was shown to provide half of the adequate selenium consumption level. Selenium supplementation decreased concentration of As, Pb, B and Sn in quail muscles and liver. Сompared to literature data selenocystine utilization enhances selenium content in egg shell more significantly than selenomethionine (Sel-Plex) that may have significant prospects in egg shell utilization.
