THE FLAT WATER GANG
GENETIC INFORMATION
The Cornerstone Cow The Cornerstone cow program is a tool for producers to utilize when selecting seed stock for their operation. The word Cornerstone is an architectural term meaning the first stone set in construction. The stone in which all the building depends. For our purpose, the Cornerstone Cow is a measure of the following:
Fertility + Production + Longevity = Profitability
This scoring model ranks the components of fertility, production to weaning, and longevity, within a herd and age group of females. The categories being scored are based upon the actual data submitted to the American Red Angus Association as a part of total herd reporting. Any cow scoring 90% or higher earns the title of a CORNERSTONE COW.
By scoring our cow herd we are attempting to provide you with an easy-to-understand value for each female in our herd. The Table below summarizes the scores for each age group of cows in production:
