However, if a producer has developed an effective genetic improvement program through superior sire selection, the improved performance in a bred heifer in comparison to a below average cow could well make up the production difference between the cow and heifer Also, the increased salvage value of the cow will aid in covering the cost of heifer development. Summary Several criteria must be applied when culling the cow herd. Cull open cows or cows not raising a calf to weaning unless economic conditions warrant retaining a pregnant cow that has not weaned a calf. Any unsoundness that impairs bearing or raising a calf to weaning or that might result in unsatisfactory performance the next year is a basis for culling. Another criterion for culling is the weight and quality of her weaned calf compared with the rest of the cow herd.
