A female stumptail macaque had signs of intermittant diarrhea and chronic weight loss over a 2-year period during which she was fed a commercial laboratory maintenance diet. Intolerance of this individual to lactose, a ubiquitous constituent of most commercial primate diets, was diagnosed on the basis of lactose tolerance tests and favorable clinical response to dietary carbohydrate substitution with glucose. Oral administration of varying doses of glucose to this animal consistently produced elevations in plasma glucose concentrations exceeding 20 mg/dl, while orally-administered doses of lactose did not cause significant elevations in blood glucose concentrations.
一只雌性短尾猕猴在两年期间出现间歇性腹泻和慢性体重减轻的症状，在此期间它食用的是商业实验室维持性饮食。根据乳糖耐量试验以及对用葡萄糖替代饮食中的碳水化合物后的良好临床反应，诊断出该个体对乳糖不耐受，而乳糖是大多数商业灵长类动物饮食中普遍存在的成分。给这只动物口服不同剂量的葡萄糖会持续导致血浆葡萄糖浓度升高超过20毫克/分升，而口服乳糖剂量则不会引起血糖浓度显著升高。
