Also known as ruminant, Ruminantia

Ruminants are herbivorous grazing or browsing artiodactyls belonging to the suborder Ruminantia that are able to acquire nutrients from plant-based food by fermenting it in a specialized stomach prior to digestion, principally through microbial actions. The process, which takes place in the front part of the digestive system and therefore is called foregut fermentation, typically requires the fermented ingesta (known as cud) to be regurgitated and chewed again. The process of rechewing the ingesta to further break down plant matter and stimulate digestion is called rumination or chewing the cu

AI overview

Ruminants are plant-eating hoofed animals with a specialized stomach that ferments plant material through microbial action before digestion, allowing them to extract nutrients from tough plant matter. They accomplish this through a process called rumination, where they regurgitate and rechew their food (called cud) to break it down further and aid digestion.

Species

反刍亚目（学名：Ruminantia）是偶蹄目中的一个亚目，其中的动物均是食草性动物，拥有分为多个胃室的胃進行反芻的動作。通过这个结构反刍亚目的动物，可以通过微生物消化其他只有一个胃的哺乳动物无法消化的糖类（比如纤维素）。除反刍亚目的动物外还有一些其他食草动物如袋鼠、叶猴属动物、马科动物和兔形目动物也可以通过微生物的帮助消化纤维素。不过这些动物不是使用胃，而是使用大肠来消化纤维素的。反刍亚目的名称来自于这些动物在休息时将半消化的食浆重新咀嚼，然后将这样再次磨碎的食物咽下，进行真正的消化。
