简单的线性相关和回归之间的几个饮食和粪便营养特性的两个黑尾鹿（Odocoileus hemionus）没有喂养四种不同的饲料。粪纤维与日粮纤维浓度相关性较差（r < 0.60）。然而，饲料和粪便氮浓度密切相关（r = 0.89）。饲料和粪便体外消化率之间也存在相关性（r = 0.94）。当野生反刍动物的饮食是低的可溶性酚类物质和单宁，百分比粪便氮浓度显示出潜在的监测饮食质量的趋势。当野生反刍动物日粮中含有高水平的可溶性酚类物质或单宁时，粪便酸性胃蛋白酶消化可能是可靠的，但这需要进一步研究。
Simple linear correlations and regressions were developed between several diet and fecal nutritional characteristics of two mule deer (Odocoileus hemionus) does fed four different forage diets. Fecal and diet fiber concentrations had poor correlations (r < 0.60). However diet and fecal nitrogen concentrations were closely correlated (r = 0.89). A correlation also occurred between diet and fecal in vitro digestibility (r = 0.94). When wild ruminant diets are low in soluble phenolics and tannins, percentage fecal nitrogen concentration shows potential for monitoring trends in diet quality. Fecal acid pepsin digestion may be reliable when wild ruminant diets contain high levels of soluble phenolics or tannins, but this needs further study.
