Bengal slow lorises () are threatened by illegal trade. Subsequently, numerous wild-born individuals are rescued and transferred to rescue centers. Metabonomic analysis of intestinal microbiomes has increasingly played a vital role in evaluating the effects of dietary alteration on the captive status of endangered non-human primates. A synthetic analysis was done to test the differences in gut microbes and fecal metabolites between two dietary groups of Bengal slow lorises across 8 weeks. Dietary interventions led to intra-group convergence and inter-group variation in the composition of intestinal flora, metabolites, and short-chain fatty acids (SCFAs). The control diet, consisting of gums and honey, significantly increased the abundance of some potential probiotics, such as and , and the concentration of some anti-disease related metabolites. The decrease in some amino acid metabolites in the original group fed without gums was attributed to poor body condition. Some distinct SCFAs found in the control group indicated the dietary alteration herein was fat-restricted but fiber deficient. Cognizant of this, plant exudates and fiber-enriched food supplies should be considered an optimal approach for dietary improvement of the confiscated and captive Bengal slow lorises.
孟加拉懒猴（）受到非法贸易的威胁。随后，许多野生出生的个体被营救并转移到救援中心。肠道微生物群的代谢组学分析在评估饮食改变对濒危非人灵长类动物圈养状态的影响方面越来越发挥着至关重要的作用。进行了一项综合分析，以测试两个饮食组的孟加拉懒猴在8周内肠道微生物和粪便代谢物的差异。饮食干预导致肠道菌群、代谢物和短链脂肪酸（SCFAs）组成的组内趋同和组间差异。由树胶和蜂蜜组成的对照饮食显著增加了一些潜在益生菌的丰度，如和，以及一些与抗病相关代谢物的浓度。在不喂食树胶的原始组中，一些氨基酸代谢物的减少归因于身体状况不佳。对照组中发现的一些独特的短链脂肪酸表明，此处的饮食改变是脂肪受限但纤维缺乏的。认识到这一点，植物渗出物和富含纤维的食物供应应被视为改善没收和圈养的孟加拉懒猴饮食的最佳方法。
