PROSPECTS OF SELENOCYSTINE UTILIZATION IN PRODUCTION OF COTURNIX COTURNIX JAPONICA MEAT AND EGGS FORTIFIED WITH SELENIUM
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.
Key words: selenium, selenotsistin, quail eggs, heavy metals.

HYGIENIC ASSESSMENT OF SELENIUM STATUS OF THE ORENBURG REGION
The work provides an assessment of the selenium status of the Orenburg Region population. The mean selenium concentration in hairs of the Orenburg residents ranged 0.153 to 0.405 mg/kg. Monitoring of selenium concentrations in food products is therefore very important for characteristics of the selenium geographical distribution. The report provides data on selenium concentrations in curd and whole milk produced in 25 districts of Orenburg Oblast. The microelement concentrations in curd ranged 102 to 341 mkg/kg, whole milk – 23 to 48 mkg /l. The mean selenium concentration in dairy products was 140 mkg/kg (curd) and 30 mkg /l (whole milk) accordingly. Heterogeneous distribution of selenium in the Orenburg Oblast dairy products has been recorded with the maximum values for the Northwestern Part – 149 mkg/kg for curd and 29 mkg /l for milk.
