Physical Characteristics:
* Teeth: Heifers have a specific pattern of tooth eruption. This method is more reliable for younger heifers, as older heifers can have worn down teeth.
* Horn Size and Shape: Angus heifers are polled (hornless), but some might have small horn buds. The size and shape of these buds can give you an idea of her age, especially if you're comparing her to other heifers.
* Body Condition: Older heifers tend to be more mature in their body shape and muscle development. This can be a rough indicator of age, but it depends on her nutrition and overall health.
* Udders: A heifer that has calved will have a larger and more developed udder than a younger heifer. However, a heifer can have a developed udder without having calved.
Other Methods:
* Ear Tag: Ear tags are often used to identify livestock and can include information about the heifer's birthdate.
* Brand: A brand can sometimes indicate the year the heifer was born, but it's not always reliable.
* Veterinary Records: If the heifer has been seen by a veterinarian, her medical records might include her birth date.
* Asking the Owner: This is the most straightforward way to get an accurate age.
Important Note:
* It's important to remember that these methods are only approximations. To determine a heifer's exact age, you would need to know her birthdate.
