相岭山系大熊猫的营养和能量对策

１９９４年至１９９６年，在冕宁县冶勒自然保护区设点，对相岭山系大熊猫的营养和能量利用进行了研究。研究结果表明，该山系的大熊猫不仅能消化食物中的粗蛋白和粗脂肪，也能部分消化半纤维素。当以秆叶为食时，其粗蛋白、粗脂肪和半纤维素消化率分别为６１．５％、５０．３％和２３．３％；而当以竹笋为食时，消化率分别为７１．９％、６１．５％和２９．６％；对竹笋中营养养物质的利用率高于秆叶。由于不同季工节食物组成、干物

Nutritive and energetic strategy of giant pandas in Xiangling Mountains

Nutrition and energy use by giant pandas in Xiangling Mountains was studied in Yele Natural Reserve,Mianning County of Sichuan Province from 1994 to 1996.Results indicated that giant pandas digested not only crude protein and crude fat,but also partial hemicellulose.Digestibility for crude protein,crude fat and hemicellulose was 61.5%,50.3% and 23.3% respectively while they ate leaves and stems.The digestibility were 71.9%,61.5% and 29.6% respectively while they took bamboo shoots only.The digestibility for...
