Do all ruminants lack upper incisors?
Ruminants such as cattle, sheep and goats are herbivores with a unique digestive anatomy. A prominent feature of ruminant dental anatomy is that they lack upper incisors, having instead a “dental pad”, as shown in the image to the right of a goat.

Why do ruminants have a unique digestive system?
Ruminants are hoofed mammals that have a unique digestive system that allows them to better use energy from fibrous plant material than other herbivores. Unlike monogastrics such as swine and poultry, ruminants have a digestive system designed to ferment feedstuffs and provide precursors for energy for the animal to use.
