Do cows have molars?
Of course! The cows need all the molars they can get. Their diet consists mainly of cellulose and digesting it requires a lot of molar work:)
Horses and cows are both herbivores, meaning their diets consist primarily of vegetation - grass, leaves, weeds, etc. Plants have very thick cell walls for each cell that is strongly attached to all the other cells around it - this is why grass stems can grow to 18" long or longer. To break down the plant fiber, horses and cattle chew their food very thoroughly and grind it in their large molars. Interestingly, though, horses…
Premolars are similar to molars but differ in function. Molars only grind whereas premolars hold and grind your food. Anatomically they are different as well. Premolars have 3 cusps where molars have 4 or 5. Premolars have two roots where molars can have 2 or 3. Premolars are succedaneous where molars are non-succedaneous. Hope that helps.
