摘要:
大熊猫是具有植食性转化阶段的特殊的食肉动物,但本身对纤维素的消化能力极低,主要依赖于肠道微生物的作用;处于食物转化阶段的大熊猫幼仔是敏感而脆弱的,对纤维素的适应消化能力也是保证其存活的关键。通过分析食物转化期大熊猫幼仔粪便中纤维素酶活性和肠道细菌多样性的变化,探讨大熊猫幼仔食物转化阶段肠道细菌性质和纤维素酶活性的相关性,以期为优化食物转化期大熊猫的饲养技术提供一定的理论指导。结果表明,大熊猫幼仔食物转化阶段纤维素酶活性变化较大,特别是增加竹子的摄入量后,大熊猫个体纤维素酶活性普遍显著增加。大熊猫肠道细菌的结构和数量在食物转化阶段也存在较大变化,且与幼仔消化纤维素密切相关,如Lactobacillus、Romboutsia等典型的肉食动物肠道菌的丰度在大熊猫幼仔肠道中数量减少,而纤维素降解菌属Cellulosilyticum的丰度明显增加,特别是大熊猫肠道优势菌属Streptococcus也表现出与其纤维素消化的密切联系。总体而言,食物转化阶段的大熊猫幼仔对纤维素有一定的适应性消化能力,其和肠道细菌菌群的演变有较大的相关性。(图3 表6 参30)
Abstract:
In order to adapt to the living environment, giant pandas have gradually formed a habit of eating bamboo, that is a special carnivore with a stage of herbivore transformation. However, the giant panda has very low digestibility of cellulose and relies mainly on the function of intestinal microbes. Giant panda cubs in the food conversion stage are sensitive and fragile, and the ability to adapt to cellulose is also the key to survival. This study analyzed the changes of cellulase activity and intestinal bacterial diversity of giant panda pups during the food conversion period, and investigated the co-relationship between bacterial properties and cellulase activities of giant panda cubs, in order to providea theoretical guide for optimizing the feeding technology of giant pandas during food conversion stage. The results showed that the cellulase activity of giant panda infants changed significantly during the food transformation stage, especially after increasing the intake of bamboo. The structure and quantity of gut bacteria in giant pandas also have great changes in the food conversion stage, and are closely related to the digestive cellulose of young cubs, such as the abundance of typical carnivorous intestinal bacteria, Lactobacillus and Romboutsia decreased, while the abundance of Cellulosilyticum was significantly increased. In particular, Streptococcus, the dominant genus of giant panda, also showed close association with cellulose digestion. In general, the adaptation of cellulose to the panda cubs in the food conversion stage is related to the evolution of the intestinal bacterial flora.
