The chart below lists the percent protein in each of the main ingredients of chicken feed: Ingredient Percent protein Dried fish flakes 76 Dried liver 76 Dried earthworms 76 Duckweed 50 Torula yeast 50 Brewers yeast 39 Soybeans (dry roasted) 37 Flaxseed 37 Alfalfa seed 35 Beef, lean 28 Earthworms 28 Fish 28 Sunflower seeds 26.3 Wheat germ 25 Peas and beans, dried 24.5 Sesame seed 19.3 Soybeans (boiled) 17 Wheat bran and/or middlings 16.6 Oats, whole 14 Rice polish 12.8 Rye 12.5 Wheat 12.5 Barley 12.3 Oats 12 Corn 9 Millet 9 Milo 9 Rice, brown 7.5 Milk 3 Whey 29 - 89 It's easy to determine the percent protein of your finished feed using this chart. For a 100 pound recipe, just multiply the percent protein of each ingredient (as a decimal) by the pounds of that ingredient in your recipe. For example, if you add 30 pounds of oats you would multiply by 0.14 and come up with 4.2. Add up the resulting numbers for each ingredient, and you have the percent protein of that batch of chicken feed. If the percent protein in a recipe is too low, maybe you should back off on the ingredients at the lower end of the chart and increase the ingredients at the upper end of the chart. For example, cut back on corn and increase your soybeans. Soon you'll be making your own recipe using the ingredients on hand!
