Three colostomised Laying hybrids received over four days a dosage of 672 mg 15N-excess (15N'), 20.3 mg lysine 15N', 23.0 mg histidine-15N' and 66.7 mg arginine-15N' with a ration customary in production. After feeding the same nonlabelled ration for another four days the hens were killed and the N-content of the blood as well as of its fractions (corpuscular components, plasma, free amino acids of the plasma) was determined.
三只行结肠造口术的产蛋杂交母鸡在四天内接受了剂量为672毫克过量15N(15N')、20.3毫克赖氨酸15N'、23.0毫克组氨酸-15N'和66.7毫克精氨酸-15N'的饲料,饲料为生产中常用的日粮。在再喂四天相同的非标记日粮后,将母鸡宰杀,并测定血液及其各部分(血细胞成分、血浆、血浆游离氨基酸)的氮含量。
