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.
Detailed explanation-2: -Ponder over, meditate, as in John tends to chew the cud before he answers, or Let me chew that over and let you know. The first term, first recorded in 1382, transfers the appearance of a patiently ruminating cow to a person deep in thought. The variant was first recorded in 1696.
Detailed explanation-3: -The ridges break the food down into smaller pieces. Then the cow regurgitates those pieces so it can chew them again. The partly-digested food that comes back into the ruminant’s mouth is the cud. The animal rechews the food with its powerful back teeth to break it down even more.
