Everyone has the really good milking, good mother cow that doesn't raise high value calves, but may be the best mother in the herd. She may have below par horns, pale color, maybe some conformation flaw, but she raises really fat calves. Maybe she is unregistered. Consider implanting those cows with up-grade embryos to raise registered cattle from known families.
Here at DCC, over the years, we have worked at helping people in several countries to start full blood Texas Longhorn herds. It requires numerous testing on the donor cow and sire. Sometimes the costs of collecting embryos is more than foreign cattlemen will pay, so we price them low. Every country is different. About 18 tests are required and once the embryos are collected certain countries, including the USA, change the regulations. They add a new test requirement that makes the already-collected embryos un-exportable. Very, very frustrating.
