Not necessarily. It really depends on the price (in $ per lb) that is currently going for culls and what class they go into. Bred cows and cows with calf at side will go for more than open cows, and fat or well-conditioned cows often will go for a higher price than thin, rangy looking cows. Most often the most money you'll get out of any cattle is the weaned calves that you sell, not the culls.
