杂食的

Carnivores have digestive systems dominated by the small intestine, which can be related to the generally high digestibility of their food. Omnivores have more complex gastrointestinal tracts, with a hindgut caecum in which some microbial fermentation takes place, and they have longer mean retention times of digesta.

食肉动物的小肠很发达，这可能与对食物的高消化能力有关；杂食性动物有更复杂的胃肠器官，其后端有可进行发酵的盲肠，消化物的平均滞留时间(meanretentiontimes ，MRTs)更长；最长的平均滞留时间见于食草动物，其消化道内高密度的微生物种群对不同滞留区内的消化物进行发酵。
