Explanation:
Detailed explanation-1: -Cud is a portion of food that returns from a ruminant’s stomach to the mouth to be chewed for the second time. More precisely, 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.
Detailed explanation-2: -Later on, they bring this food (cud) back to their mouth and chew it again. This process of chewing cud is called rumination and these animals are called ruminants.
Detailed explanation-3: -According to dairy cow nutritionist Mary Beth de Ondarza, when a cow is chewing her cud, that’s a good sign. It means that she is comfortable, relaxed and eating a good diet with a sufficient amount of long fiber.
