Dental pad of domestic livestock. Note the lack of upper incisors and canine teeth.

Thedental padorbrowsing padis a feature ofruminantandcamelids[1]dental anatomy that results from a lack of upperincisorsand helps them gather large quantities of grass and other plant matter.[2][3]This feature can be found in ruminants such ascattleandsheep.In cattle, thetongueis used to grasp food and pinch it off between the dental pad and the lower incisors. However, since they cannot bite grass off, they are inefficient at grazing more closely than 6 inches (15 cm) from the ground.[3][4]
