The protein content in the diet affects the amount of serum protein and fraction distribution in gnotobiots. Germ-free pigs and guinea-pigs which received the diet containing the least amount of protein showed an abrupt decrease in the total protein level in blood serum. As regards the content of alpha- and beta-globulins, no significant differences were found in blood serum of experimental animals. The amount of alpha-blobulin in germ-free animals which received the protein-deficient diet was 1 1/2-2 times higher than in those which received protein in an amount meeting the physiological requirements. It was established that 4-8% of protein in the diet of 2-month-old germ-free pigs and 14-18% in the diet of germ-free guinea-pigs favour the normal growth and development of experimental animals.
饮食中的蛋白质含量会影响无菌动物血清蛋白的含量和组分分布。食用蛋白质含量最低的饮食的无菌猪和豚鼠，其血清总蛋白水平急剧下降。关于α-球蛋白和β-球蛋白的含量，在实验动物的血清中未发现显著差异。食用蛋白质缺乏饮食的无菌动物体内的α-球蛋白含量比食用满足生理需求量蛋白质的动物高出1.5至2倍。已确定，2月龄无菌猪饮食中4-8%的蛋白质以及无菌豚鼠饮食中14-18%的蛋白质有利于实验动物的正常生长发育。
