First sheep like cattle, goats, and deer are ruminates. Ruminates are a miraculous gift of God. Ruminates have multi-chambered stomachs which includes the rumen in which microorganisms break down plant material including cellulose. Ruminates take plant parts that people cannot digest, and transform it into a high protein food for mankind.
Sheep graze and browse quickly then later they lay down regurgitate and re-chew their food, this is called chewing the cud or ruminating. Sheep ruminate several hours a day.
Most people, when they see the word “sheep” think of woolly sheep.
