摘要: 2008 年12 月至2009 年2 月,对贵州麻阳河自然保护区黑叶猴的18 种冬季主要食物以及13 种取食较少的
次要食物的各取食部位进行采集。对各独立样本的水分、粗蛋白、粗纤维、酸性洗涤纤维(ADF)等营养成分
分别以凯氏定氮法、酸碱洗涤法和范式洗涤法进行测定,并计算相应的粗蛋白/酸性洗涤纤维(PROT/ ADF)比
值。将各独立样本的测定营养组分以及PROT/ADF 比值数据与相应的冬季采食数据进行相关性检验。测定结果
显示:除PROT/ADF 比值有明显的差异外,主要食物与次要食物在其他测定组分上均没有显著性差异。并且18
种主要食物的各测定营养组分以及PROT/ADF 比值与相应的冬季采食比例之间均没有显著的相关性。检验结果
说明麻阳河黑叶猴冬季对食物物种的选择不受其测定营养组分含量和PROT/ADF 比值的影响。冬季采食的4 种主要采食部位除水分含量存在极显著差异外,在其他营养组分含量以及PROT/ADF 比值上均没有显著差异,且
相关性检验结果表明各采食部位的冬季采食比例与其测定营养组分以及PROT/ADF 比值之间均没有显著相关性。本研究结果表明,麻阳河黑叶猴的冬季食物选择不受食物水分、粗蛋白、粗纤维、ADF 含量和PROT/ADF 比值的影响。

Abstract: From Dec. 2008 to Feb. 2009,we collected samples of 18 major winter food species and of 13 lesser-used food species of Francois’langur at Mayanghe Nature Reserve. We determined the water,crude protein,crude fiber,and acid detergent fiber (ADF),and calculated the ratio of crude protein and acid detergent (PROT/ ADF)of each sample,and tested the correlation between nutritional data and winter feeding proportion of each sample via Spearman Correlation Rank. Results showed that,except the PROT/ ADF ratio,there were no significant differences between the major and lesser-used species in nutritional contents. Further,there were no significant correlations between the winter feeding proportions of the 18 staple species and their corresponding nutritional contents,suggesting that the food species choice of the langurs in winter was not influenced by the content of water,crude protein,crude fiber,ADF and PROT/ ADF. Except for the content of water,there were no significant differences between food components in other measured components,and no significant correlations
between winter feeding record and corresponding nutritional contents of each component,indicating that the choice of food components in winter was also not influenced by the content of water,crude protein,crude fiber,ADF and PROT/ADF.
