众所固知,大豆和蛋黄都含有大量的铁。但是,目前对二者的铁的生物利用率的评价尚有较大争议。为此,本研究用大鼠血红蛋白再生试验测定了大豆粉和蛋黄粉中铁的相对生物利用率。用低铁基础饲料喂饲动物四周使之严重贫血。从中选100只分为十组,一组(O组)继过续摄入低铁基础饲料,其余九组分别喂 As everyone knows, both soy and egg yolk contain a lot of iron. However, the current assessment of the iron bioavailability of the two is still controversial. For this reason, the relative bioavailability of iron in soy flour and egg yolk powder was determined in a rat hemoglobin regeneration assay. Feeding animals around low-iron basal feeds causes severe anaemia. From the middle of the selection, 100 were divided into 10 groups, one group (O group) continued to ingest low-iron base feed, and the remaining nine groups fed
