(Stamp of success Part 4 of 6)  Andrew Grierson from Woodlands Stud believes a focus on the sire alone can be misleading.  “Half the genes come from the mare, so it is a bold statement to say that a sire ‘stamps’ his progeny,” he comments. “However you can see sire lines that produce certain qualities. For example, Bettor’s Delight comes from a sire line that produces sound horses. His foals tend to have good feet, good conformation, and don’t break down. It’s about bone density.”

Bettors Delight is a smaller (15.1 hand) stallion, but like Courage Under Fire’s reputation for heart and gait, Bettor’s Delight offsets any size concerns with a growing reputation for leaving progeny with soundness and speed. “New Zealand breeders have to get out of the mentality that a small horse is no good,” he says.
