If a producer wishes to include non-production traits in a breeding program, they should be added in a way that does not seriously jeopardize the emphasis placed on the production traits. Selection should first be placed on the production traits. Then, mating of individual cows can be based on the non-production traits of those sires of interest. If you initially select sires on non-production traits, it can seriously affect income because of decreased production. Always select on the traits that generate the most income.
