Inside every good bull is a pen full of bulls, steers and heifers trying to get out. Some of these will be as good as their sire. Some will be better. Some will be worse. Observation of a bull tells little about how much genetic superiority he can pass on to his sons and daughters. Measurements are needed. Identifying the superior offspring – the bulls that have the capacity to produce better offspring - is a science.
