"In my experience in working, co-owning and managing a 1,200 head commercial cow-calf operation, I learned from many years of trial and error and have made the following conclusions.
A cow must be able to calve unassisted without problem and the calf must be vigorous to rise and nurse in all weather situations including snow, wind, and sub freezing temperatures.
The cow must have enough milk to wean a heavy calf that will continue to grow on pasture and in the feedlot with efficiency and then produce a carcass of premium value.
The female must have the fertility to breed back on time and remain productive in the herd for at least 10 years plus. That means sound feet and legs and good teeth.
In order to achieve these results, I have focused on maintaining moderate framed genetics that are easy fleshing and of docile temperament. Once a ranch has reached full cow-calf carrying capacity, each and every calving female must bring in an acceptable calf at weaning. Non-producers are culled from the breeding herd. No second chances. In running a seedstock operation with a commercial cattleman's mindset and selection pressure, only the best are produced and supplied to the bull buyer's market."
