While an ox is grazing, the food is swallowed without mastication, and, together with saliva, passed directly into the rumen, or paunch, and reticulum. After the animal finishes eating, the food is brought back to the mouth — a small quantity at a time, which constitutes the cud — and is thoroughly masticated.
