Goats have one stomach, but unlike humans, their stomach features four separate compartments. The four parts of a goat's stomach are called the rumen, reticulum, omasum and abomasum.
Belonging to the ruminant animal group, goats digest roughage through a four-part process. As fresh food is consumed, it enters the rumen. The rumen absorbs certain nutrients, while enzymes and bacteria break down plant fibers. Once the food is broken down, the goat regurgitates its feed and chews on it again. As food particles become small enough through several acts of regurgitation, they are passed to the reticulum, where foreign objects are filtered through its honeycomb structure. From there, food particles pass to the omasum, where water is removed and more nutrients are absorbed. Finally, the remaining food particles are sent into the abomasum, where non-digested food particles are broken down with hydrochloric acid and sent into the small intestine.
