At Vastrap Boran, we verify the parentage of every stud animal through DNA testing at Unistel laboratories. This is not only because we use more than one bull in each breeding herd (multi-siring), but also because we believe that it is crucial to establish the parentage of our animals with 100% certainty.
The confirmation of the parentage of stud animals through DNA testing is still not compulsory in most cattle breeds, but there is a strong case that it should be. In our opinion, if the parentage of an animal is not accurate, the animal should no longer be called a stud animal and would be no different from a commercial animal. When buying a stud animal the parentage of that animal determines two out of the three criteria that one looks at to assess its breeding potential, namely genetic make-up and performance data. Even if an animal’s physical attributes are absolutely perfect, that counts for nothing in the world of stud breeding if it’s parentage cannot be verified.
In Quentin’s short time as a stud breeder, he has tried to learn from as many experienced breeders as possible. He has been fortunate to have interactions with many breeders who have much more knowledge about stud breeding than him. These include some of South Africa’s most prominent breeders in their respective breeds, Philip Barnard (Angus), Bernie Staal (Brahman & Boran) and Arthur de Villiers (Bonsmara). In chatting to them about what to look for in a stud bull, the common theme has been to use a balanced approach. A buyer needs to look at the bull’s physical attributes, at the bull’s performance data and at the bull’s genetic make-up (or parents).
Without parent confirmation through DNA testing a breeder/buyer cannot be 100% sure of the parentage of an animal. Errors can occur with allocating the sire of a calf in many ways. There can be errors in record keeping. A female can be accidentally allocated to an incorrect breeding group. The documentation with the pairing data can be lost or damaged. A stray bull can jump a fence while you are away and you are either unaware or your staff do not tell you for various reasons. One may even just plainly forget to write it down timeously. In short, it happens all the time even in the best-managed herds!
