From its initial introduction until the present day, the principles of aAa® and Weeks® Animal Analysis have never changed, although the format has been simplified and refined. As his own experience evolved, Bill Weeks simplified his original “round and sharp” analysis into the six distinct qualities we know today as, #1 Dairy, #2 Tall, #3 Open, #4 Strong, #5 Smooth, and #6 Style.
Bill Weeks stated that these six qualities are of equal importance and they are all essential to the vital functions and performance of a dairy cow. The ideal dairy cow would achieve a perfect balance of these six qualities. Each of the six qualities is a combination of positive characteristics. Dairy breeders can bring these qualities and characteristics into balance by using the information provided by aAa® and Weeks® Animal Analysis.
