【摘要】 研究了笼养条件下白头叶猴觅食的行为序、雌雄个体对食物的选择、夏季和冬季的日食量．笼养白头叶猴的觅食行为序由探究行为、抢食行为、爬墙行为和进食行为等4步组成．除探究行为的持续时间在雌雄个体间有显著性差异外，其他行为持续时间无显著的性别差异．雌雄个体对食物的选择不同，包括对某一食物的取食先后顺序、取食时间和取食量的不同．雄猴和雌猴的日食量夏季分别为（659．3±136．3）g和（590．7±106．3）g，冬季分别为（749.4±135．1）g和（640.1±96．9）g，T检验表明，笼养雄猴和雌猴的日食量夏季与冬季无显著的季节性差异，而雄猴与雌猴的日食量无论是夏季或冬季都有显著的性别差异．更多还原

【Abstract】 The sequence of feeding behavior, food selection of male and female individuals and daily feeding quantity in both summer and winter of White - headed leaf monkey (Presbytis leucocephalus) in capivity were studied. In captivity, the sequence of feeding behavior consisted of four parts which were investigating behavior, snatching behavior, climbing behavior and eating behavior, except the durations of investigating behavior between male and female had significant difference, the others did not showed signment difference by T test. Food selections of male and female had difference which which the sequence difference of male and female choosing a food and the difference of the time and quantity of male and female eating a food. The daily feeding quantity of male and female were (659.3 ± 136.3)g and (590.7± 106.3)g in summer and (749.41±135.1)g and (640.1± 96.9)g in winter respectively. For the daily feeding quantity of male or female both in summer and winter, it was not different. It was significant different that the daily feeding quantities between male and female both in summer and winter by T test.更多还原
