A significant cost on farms is that of raising replacement animals. Acerbating it are low forage rations and overcrowding that stress the mature cows and increase the culling rate. Thus, you need even more replacement animals which is more cost. High forage diets (if you have enough quality forage), reduced crowding, and animal comfort can go a long way reducing this high culling cost and the animals to replace them. These changes take time. There is a step you can take to grow better heifers at less cost starting this year.
