The mother is the only cow in 5 generations that has had less than 13 calves. This would be talking about both sides of pedigree. The only reason she has had less calves than that is because she is only 8 years old. For a cow calf operation it would make sense to eliminate cows before this age. However if a cow will last this long for use, just imagine what age of cow the DDA George 106A will produce.
