饲喂中草药和微量元素硒提高蛋的营养价值的研究

STUDIES ON RAISING THE NUTRITIVE VALUE OF EGGS BY ADDING MEDICAL HERBS AND TRACE ELEMENTS IN SELENIUM FEEDS FOR LAYING-HENS

本项研究系应用中草药和微量元素硒配伍的特制预混料，对蛋鸡进行了３次饲养试验。试验结果表明，蛋鸡在饲喂了这种特制预混料后所产的蛋平均含硒量可稳定地由对照组的每枚４３μｇ，提高到１２０～２７５μｇ，成为一种富硒蛋。这种蛋经实验动物安全试验和人医临床试验，均无毒副反应。受试对象按规定量连续服用３个月后表现在血清硒、发硒的含量和血清中谷胱甘肽过氧化物酶（ＧＳＨ—Ｐｘ）的活性均比服用前明显提高，差异极显著（Ｐ＜０．０１）。这些指标的升高表明富硒蛋可以方便、安全地补充人体生理需要量的有机硒．作者认为这种富硒蛋可以提高人体的免疫功能和抗衰老以及预防心血管疾病等作用，将为人们提供一种多功能性的天然绿色保健食品。

Three feeding trials on laying-hens were conducted to study the effect of a complex feed additive made up of medical herbs and trace element selenium. The results showed that the average selenium content of the eggs laid by the hens which had been fed on the additive was 120-275μg per egg, more than three times that of the eggs laid by the control group hens. Neither laboratory nor clinic observation werefound any toxicosis or side effect resulting from the selenium-enriched eggs. After taking the fixed doses of selenium-enriched eggs for three months running,the patients had serum selenium, hair selenium and GSH-Px activity levels increased significantly. So using selenium -enriched eggs. to supply the patient's physiological need for organic selenium is effective, as well as being easy and safe as a method. The authors are of the opinion that since it can improve the immunity functions and prevent ageing, the selenium -enriched egg will be a natural healthy food, especially for the elderly.
