Abstract

In order to study the effects of a zinc-supplemented dietary rapeseed protein concentrate on the contents of zinc and some other minerals in plasma, liver and bone tissue as well as on the levels of tocopherol, lipoproteins and lipids in plasma and total lipid contents of livers, groups of young female rats were fed for 4-week periods on semi-purified diets containing either rapeseed protein or casein as the sole source of protein at a 20% protein level. Despite normal levels of tissue zinc and plasma proteins, rats on diets and tocopherol in comparison to the casein-fed rats. Rats on rapeseed diet also seemed to have an increased lipid content of the liver possibly indicating a reduced hepatic synthesis or secretion of lipoproteins. In addition the livers of rats fed on rapeseed protein diet showed a reduced iron content.

饲喂补锌油菜籽蛋白饲料的雌性大鼠血浆、肝脏和胫骨中矿物质、脂蛋白和脂质的水平。
为了研究饲粮中添加锌的油菜籽浓缩蛋白对血浆、肝脏和骨组织中锌和其他矿物质含量的影响,以及对血浆中生育酚、脂蛋白和脂质水平和肝脏总脂质含量的影响,采用以20%蛋白质水平的油菜籽蛋白或酪蛋白为唯一蛋白质来源的半纯化饲粮,饲喂4周。尽管组织锌和血浆蛋白水平正常,但与酪蛋白喂养的大鼠相比,饮食中的大鼠和生育酚含量有所下降。食用油菜籽的大鼠肝脏脂质含量似乎也有所增加,这可能表明肝脏脂蛋白合成或分泌减少。此外,食用菜籽蛋白饲料的大鼠肝脏铁含量降低。
