We have developed a dilution method for avian urine and modified existing analytical methods for ammonia, urea, uric acid and total nitrogen to permit determination of all these compounds on aliquots of the same urine sample. The proportions of urinary nitrogen in these compounds were: uric acid 55-72%, ammonia 11-21% and urea 2-11%. This ranking of proportions was consistent for four different dietary protein-water availability regimes. There were no significant differences in the proportions of these nitrogenous compounds due to either dietary protein intake or changes in water availability.
我们开发了一种禽类尿液稀释方法，并对现有的氨、尿素、尿酸和总氮分析方法进行了改进，以便能够对同一份尿液样本的等分试样进行所有这些化合物的测定。这些化合物中尿氮的比例分别为：尿酸55 - 72%，氨11 - 21%，尿素2 - 11%。在四种不同的饮食蛋白质 - 水分供应模式下，这些比例的排序是一致的。由于饮食蛋白质摄入量或水分供应变化，这些含氮化合物的比例没有显著差异。
