Did you know that cattle don't get all their permanent teeth until they're 5 years old? The lower front teeth, known as incisors, come in over a period of years, 2 pair at a time, starting with the two center teeth. This means that you can tell the age of your animals by how many of the front incisors they have. You can also tell if an cow is nearing the end of her productive years and is ready to be marketed by looking at the condition of her incisors. This 4 minute video from Mississippi State University will show you how to open the cow's mouth safely to look inside, and then how to figure out how old your animal is based on what you see inside.
