人类膳食与肿瘤及其他疾病有密切关系,因此在做动物致癌和毒理试验时,动物饲料就是一个十分重要的因素。对试验动物的饲料须注意以下四点: 1.种系间代谢率的差异即使同是成年动物,不同种系之间在代谢率上也有很大的差别。例如,一个体重200 g的成年大鼠和一个60kg体重的成人的热能需要量分别是80 kcal/日 Human diet and cancer and other diseases are closely related, so in animal carcinogenesis and toxicology tests, animal feed is a very important factor. The following four points should be noted for the feed of experimental animals: 1. Metabolic rate differences between germ lines Even in adult animals, metabolic rates vary greatly among germ lineages. For example, an adult with a body weight of 200 g and an adult with a body weight of 60 kg have a heat energy requirement of 80 kcal / day
