The real difficulty in reading sire data today is the complexity of available trait scoring and ranking systems. The less time we have, the more we depend on simple ranking indexes (Holstein TPI) (Jersey JPI) (Net Merit $) and thus ignore the underlying patterns that more clearly define reasons for each bull to either be used [he can help us] or avoided [he offers nothing exceptional].
