Ko Shen-jen, head of the Large Animal Unit of the NTU Laboratory Animal Management Committee, tells us that small lab animals like mice, hamsters and guinea pigs are used mostly for cellular and genetic research, and much of the time only blood needs to be drawn. But some experiments require researchers to closely observe physiological reactions in animals, and in such cases large animals have to be used.
台大實驗動物管理委員會「大動物組」組長柯世禎表示，小鼠、倉鼠、天竺鼠等小型實驗動物大多用在細胞或基因的研究，許多時候甚至只需抽取血液即可，但有些實驗要求研究者親眼看到動物的生理反應，這時就需用到大動物。
