| 摘 要： | 用低硒地区饲料（Ｓｅ０．０１０ｍｇ／ｋｇ）、同一地区施硒肥的饲料９Ｓｅ０．０９６ｍｇ／ｋｇ）和补加亚硒酸钠的饲料（Ｓｅ０．０５５ｍｇ／ｋｇ和Ｓｅ０．１１０ｍｇ／ｋｇ）分别喂养大鼠１７周，以谷胱甘肽过氧化物酶（ＧＰＸ）活力和硒含量为指标求得施硒肥粮中硒的相对生物利用率（ＲＢＡ）。结果表明，施硒肥粮硒的ＲＢＡ，以ＧＰＸ活力为指标时，肝肾中分别为８１和７８；以组织硒为指标时，则分别为１４２和３９１。硒肥

| Abstract: | Four groups of rats were fed with: (1 )the Se-deficient grain basic diet (Se 0.010mg/kg), (2) the selenite - fertilized grain from the same area basic diet (Se 0.096mg/kg), (3) the selenite supple- mented grain basal diet (Se 0.055mg/kg)and(4)the selenite supplemented grain basal diet (Se 0. 110mg/kg) for 17 weeks. Activities of glutathion peroxidase (GPx) and selsnium levels were used as the indicator study and calculate the relative bioavailability (RBA) of selenium in Se- fertilized grain. The results indicated that RBA of sekenium in Se- fertilized grain , taking GPx activity in heart,liver and kidey as the indicator, were182,81and78,respectively,taking selenium level as the indicator,were127, 142and391 , respectively . The matural form of selenium in Se - fertilized grain has an advantage over Na2 Se03 in increasing the body selenium level. GPx activity in heart. |
