Yes.
"The cow chewed its cud." Cud (noun), partly digested food returned from the first stomach of ruminants to the mouth for further chewing. A ruminant is an animal that has a stomach system such that it chews its cud. This includes cattle, sheep, antelopes, deer, giraffes, and their relatives.
Cud is a portion of food that returns from a ruminant's stomach to the mouth to be chewed for the second time. More accurately, it is a bolus of semi-degraded food regurgitated from the reticulorumen of a ruminant. Cud is produced during the physical digestive process of rumination.
Cud
The rumen is a 'pouch' where the cud is stored in ruminant animals such as cattle, goats, giraffe, sheep, and deer. The cud is then returned to the mouth and is re-chewed.
That is the cud that they chew. It is food that is partially chewed, then swallowed, then regurgitated later to be chewed on some more. That is how many grain-eating animals manage to digest so much fiber.
Partially digested forage that was in the rumen is moved into the reticulum from the contractions of the rumen. The esophagus "transports" the bolus of cud up fromt the reticulo-rumen to the mouth to be chewed.
Cud-chewing animals are called ruminants. Ruminants are any hoofed mammal that digests its food in two steps. In the first step, the food is chewed and partially digested in the mouth. The food is then regurgitated and chewed again (the cud). This second step allows the animal to extract more nutrients from the food. Ruminants include cattle, sheep, goats, buffalo, deer, and camels.
Clarice Cow chewed cud carefully. Chester can claw crabs. There are as many as the imagination can create...
Any animal that had a split hoof, such as a cow has a split hoof, and chewed its cud much like a cow also chews its cud, was fit for food. As for fish, they had to have scales. Also the animals could not be scavengers.
'Cud' is the regurgitated food that a ruminant animal is 're-chewing'. Ruminant animals (Cattle, Sheep, Goats) have a four chambered stomach that allows them to digest their food better. the food cannot pass through the first chamber, the Rumen, until it has been sufficiently chewed. to accomplish this, the ruminant animal will requrgitate the food and chew it again. This food that it regurgitates is the cud.
It relaxes from eating, and enables the partly eaten forage to be chewed more thoroughly during this rest period so that more nutrients can be gleaned from it.
They are re chewing undigested feedstuffs. Cattle are designed to continuously eat until they have filled their first stomach (the Rumen). When they are safe from predators, they will enter their resting state. At this point in time they will lie down and chew the undigested feedstuffs from the first stomach, swallow and put it in the next stomach. This process will repeat until all four compartments are filled and feed has been completely digested and chewed.
