17% Layer Ration: 965 lb. Shelled Corn 600 lb. Roasted Soybeans 100 lb. Oats 100 lb. Alfalfa Meal 175 lb. Aragonite(calcium) 60 lb. Poultry Nutri-Balancer 2000 lb. I found this mix online and was wondering how it would work. And it says you can take the alfalfa meal out and just add 100 more pounds of oats. What doe the alfalfa meal do ????
