Analysis of the nutritional position and antioxidative effect of the embryo extract from chicken
ABSTRACT: Objective To analyze the nutritional position, and explore the antioxidation and selenium supplement of the embryo extract from chicken(EEC). Methods The nutritional position ined by the national standard technique. The animal test used the method of Seleniummalnutrition in mice. Totally 100 healthy male mice ice in highdose, mediumdose, lomalnutrition control group malnutrition forage, on forage; from the 5th to the end of 8th ediumdose, or log, Fe of , Se of , vitamin A of 1679μg,.freelin D of , and vitamin B2 of . In animal test by the end of the 8th alnutrition group, the blood selenium level in mice of EEC highdose, mediumdose, loice enhanced ice declined (P ). Conclusion EEC is an excellent protein. It contains rich mineral elements and vitamins. It may efficaciously improve the status of seleniummalnutrition in mic
