What is regurgitated food in a ruminant animal commonly known as?

In ruminant animals, the term for regurgitated food is commonly known as cud. When these animals, such as cows and sheep, initially chew their food, it goes to the rumen, where it undergoes fermentation. Eventually, they regurgitate this partially digested food back into their mouths as cud, which allows them to chew it again and break it down further. This process is essential for better digestion and absorption of nutrients from their plant-based diet.

The other terms listed relate to different aspects of animal nutrition or feed: a bolus generally refers to a mass of food that is swallowed, fodder signifies feed for livestock, and ration denotes a portion of feed given to an animal for a specific time. None of these terms specifically address the regurgitation process that is a characteristic feature of how ruminants digest their food.
