摘　　要：在人工饲养亚洲象(Elephas maximus)的过程中,饲料营养是其健康状况的重要影响因素之一,但关于亚洲象饲料以及消化率相关的研究较少。为测定亚洲象日粮营养成分含量及摄入量、养分消化率,选取5头北京动物园圈养的成年亚洲象为试验动物,分析其冬季日粮的营养成分,同时收集粪便,测定其表观消化率。结果表明:亚洲象干物质采食量占其体质量的0.66%~1.20%,个体间养分消化率存在差异。试验用饲料干物质、粗蛋白、粗纤维、粗脂肪、钙和磷的平均消化率分别为(51.0±2.7)%、(67.2±2.4)%、(48.7±2.9)%、(57.6±3.3)%、(48.3±8.5)%和(61.8±6.0)%。研究结果可为进一步开展有关亚洲象的营养及饲料配方设计提供基础理论数据。Feed nutrition is one of the important factors for their health status in the breeding of captive Asian elephants(Elephas maximus),but there are few studies on the feed and digestibility of Asian elephants.Therefore,we selected five adult Asian elephants in captivity in Beijing Zoo to analyze the nutrient content of their winter diet,and determine apparent nutrient digestibility.The results showed that:the apparent digestibility of dry matter,crude protein,crude fiber,crude fat,calcium and phosphorus were(51.0±2.7)%,(67.2±2.4)%,(48.7±2.9)%,(57.6±3.3)%,(48.3±8.5)%,(61.8±6.0)%,respectively.The experiment provided theoretical data of feed formulation and nutrient digestibility for captive Asian elephants.
