How Do Cattle Moo?

Cattle moo by vibrating their vocal cords. The sound of a cow's moo is produced when air passes through the larynx and causes the vocal cords to vibrate. The pitch of the moo is determined by the length and tension of the vocal cords. Cows can produce a variety of different sounds, including moos, bellows, grunts, and snorts. Each sound has a different meaning and is used to communicate with other cows.
