Corn does not make up 100% of the diet. The diet of cattle is usually a mixture of many feeds, mixed in the correct proportions to give the animal what it needs for its stage of growth or production.

The Tongue. The tongue is a muscular organ in the mouth with several functions. It is attached to the bottom of the mouth by a membrane on its underside called the lingual frenum. The top surface of the tongue contains papillae, the tiny nodules or bumps that include the taste buds. One of the functions of the tongue is taste, but it also facilitates chewing, digesting, swallowing and speaking.
Taste buds contain the receptors for taste. They are located around the small structures on the upper surface of the tongue, soft palate, upper esophagus, the cheek, epiglottis, which are called papillae. Circumvallate papillae-there are only about 10 to 14 of these papillae on most people, and they are present at the back of the oral part of the tongue. 2  They are arranged in a circular-shaped row just in front of the sulcus terminalis of the tongue.
