摘要
为进一步研究老龄大熊猫的营养需求,于2017年8月—2018年7月,采用全收粪法研究重庆地区圈养老龄大熊猫对不同主食竹营养成分的表观消化率。结果显示,老龄大熊猫以竹笋为主食,适口性好,日食入干物质(1633.34±449.58)g,粗蛋白、粗脂肪、总能表观消化率分别为(70.80±4.66)%、(55.72±7.04)%、(52.33±3.65)%,高于以竹叶为主食粗蛋白、粗脂肪、总能表观消化率(52.86±6.53)%、(46.50±9.33)%、(46.16±4.48)%;以竹笋为主食粗纤维消化率为(21.64±4.52)%,低于以竹叶为主食粗纤维的表观消化率(32.32±3.35)%。高龄大熊猫饲料中以竹笋为主食更利于其消化吸收,对刚步入老龄阶段的大熊猫以竹叶为主食,更利于大熊猫健康。该结果为大熊猫提供优质的食物资源具有指导意义。
In order to further investigate the nutritional requirements of elderly giant pandas,a study was conducted using the total fecal collection method in the Chongqing region from August 2017 to July 2018.This study aimed to assess the apparent digestibility of different nutritional components in bamboo,the primary food source for captive elderly giant pandas.The results revealed that when elderly giant pandas primarily consumed bamboo shoots,they exhibited good palatability,with a daily intake of dry matter at(1633.34±449.58)g.The apparent digestibility of crude protein,crude fat,and total energy was(70.80±4.66)%,(55.72±7.04)%and(52.33±3.65)%,respectively,which was higher compared to those consuming bamboo leaves as the primary food source,with crude protein,crude fat,and total energy digestibility at(52.86±6.53)%,(46.50±9.33)%and(46.16±4.48)%.Furthermore,when bamboo shoots were the primary food source,the digestibility of crude fiber was(21.64±4.52)%,which was lower than the apparent digestibility of crude fiber when bamboo leaves were the primary food source(32.32±3.35)%.Consequently,in the dietary management of elderly giant pandas,bamboo shoots as the primary food source are more beneficial for their digestion and absorption.On the other hand,for giant pandas entering the elderly stage,bamboo leaves as the main food source are more conducive to their overall health.These findings hold significant guidance for providing high-quality food resources for giant pandas.
