Why do lambS eat grass?

Lambs eat grass primarily because it is a natural source of nutrition that provides them with the necessary vitamins, minerals, and energy for growth. As herbivores, their digestive systems are specifically adapted to process fibrous plant material, allowing them to efficiently extract nutrients from grass. Grazing on grass also helps promote healthy digestion and supports their overall well-being. Additionally, eating grass is a learned behavior, as they observe and mimic adult sheep.
