摘　　要：用全收粪法研究了圈养大熊猫对雷竹笋营养成分的表观消化率。结果表明:1)4只大熊猫对粗蛋白、粗脂肪的平均表观消化率分别为89.44%±1.67%和76.22%±8.67%;对中性洗涤纤维、酸性洗涤纤维、半纤维素的平均表观消化率分别为21.88%±7.43%、11.78%±5.69%和30.79%±7.46%。大熊猫对各种矿物元素的表观消化率中,Cu元素的平均表观消化率最低,为19.05%±11.07%;P元素表观消化率最高,为66.98%±6.24%。2)成年大熊猫与亚成年大熊猫粗蛋白的消化率无显著差异(P>0.05);亚成体大熊猫粗脂肪的表观消化率极显著高于成体大熊猫(P<0.01);雌性亚成体大熊猫对中性洗涤纤维、酸性洗涤纤维、半纤维素以及矿物元素P、Ca、Mg、Cu、Zn的表观消化率显著高于其他3只大熊猫(P<0.05)。这些结果对于拓展浙西地区优质的大熊猫食物资源具有重要意义。Apparent digestibility of nutrient components in bamboo shoots of Phyllostachys violascens intaken by captive giant panda was studied based on feces collection.The results showed that the average apparent digestibility of crude protein,crude fat,neutral detergent fiber（NDF）,acid detergent fiber（ADF） and hemicellulose was 89.44%±1.67%,76.22%±8.67%,21.88%±7.43%,11.78%±5.69% and 30.79%±7.46% respectively.Among the average apparent digestibility of minerals such as P,K,Ca,Na,Mg,Cu,Zn and Mn,the lowest was 19.05%±11.07% for Cu the highest was 66.98%±6.24% for P.There found no significant difference in the apparent digestibility of crude protein between adult and sub-adult giant panda.While,the apparent digestibility of crude fat of sub-adult giant panda was significantly higher than that of adult giant panda.The apparent digestibility of NDF,ADF,hemicellulose,P,Ca,Mg,Cu and Zn of the female sub-adult giant panda was significantly higher than the others.The research has important significance to develop high quality food resources for captive giant panda in West Zhejiang.
