The acceptability and digestibility of a high-fiber biscuit-based diet was investigated using two adult male Colobus guereza animals. Although the animals were initially reluctant to accept the biscuit, it was eventually readily consumed. Apparent digestion coefficients for the diet (average composition, dry matter basis: 16% crude protein, 25% neutral detergent fiber (NDF), 9.5% acid detergent fiber (ADF), 1.2% acid lignin) determined by total fecal collection were 0.871 for dry matter, 0.813 for NDF, 0.693 for ADF, and 0.208 for acid lignin. Fiber digestive capabilities in C. guereza generally exceeded those reported in ruminant species based on predictive equations. Use of acid lignin and Cr O as markers underestimated dry matter digestibility by 3.9 and 6.0%, respectively.
使用两只成年雄性黑白疣猴对基于高纤维饼干的饮食的可接受性和消化率进行了研究。尽管这些动物最初不愿接受饼干，但最终还是欣然食用。通过全粪收集测定的该饮食（平均组成，以干物质计：16%粗蛋白、25%中性洗涤纤维（NDF）、9.5%酸性洗涤纤维（ADF）、1.2%酸性木质素）的表观消化系数为：干物质0.871、NDF 0.813、ADF 0.693、酸性木质素0.208。基于预测方程，黑白疣猴的纤维消化能力通常超过反刍动物物种的报告值。使用酸性木质素和氧化铬作为标记分别低估了干物质消化率3.9%和6.0%。
