The American Angus Association and Angus Genetics Inc. (AGI) have a great informational page about the different DNA sample collection types and best practices for each. If you have any questions about which sample type may be best for your operation, reach out so we can discuss. Keep in mind, you can apply this logic across any breed association business you work with, it’s not exclusive to black Angus cattle.
