Based on a comparison between colostomy, the alpha-NH2-N method introduced by PAHLE et al. (1983, 1985), the HARTFIEL (1963) and the EKMAN (1948) methods of the separation of faecal N and urine N in the determination of the apparent digestibility of crude protein in chickens, extensive studies were carried out with mixed excrement from colostomy experiments and excrement samples from intact animals from digestibility experiments with different feedstuffs. In case of the application of the methods by HARTFIEL and EKMAN there were partly big deviations in the measured results. A modification of the alpha-NH2-N method applied by us showed results which largely agreed with the results of colostomy and the method developed by PAHLE.
基于结肠造口术、PAHLE等人（1983年、1985年）引入的α-NH2-N法、HARTFIEL（1963年）法以及EKMAN（1948年）法在测定鸡粗蛋白表观消化率时粪便氮和尿液氮分离方法之间的比较，我们利用结肠造口术实验的混合排泄物以及不同饲料消化率实验中完整动物的排泄物样本进行了广泛研究。在应用HARTFIEL法和EKMAN法时，测量结果部分存在较大偏差。我们应用的α-NH2-N法的改进方法显示的结果与结肠造口术结果以及PAHLE开发的方法结果基本一致。
