Corn and Wheat as the Main Part of Laying Rations

POULTRY laying rations are made up largely of cereals and cereal by-products. Under ordinary conditions a combination of such cereals as corn, wheat, and oats are included. However, there are times when there are available greater and cheaper supplies of one grain or another. Then the question arises: “How much of this cereal can I feed?” This has been true of wheat during the current year. Wheat has more protein but less fat than has corn. Wheat products contain more manganese than does corn. Wheat and its products contain only traces of vitamin A, whereas yellow corn has a considerable quantity of this vitamin. On the other hand, wheat and its by-products are richer in the vitamin B complex than corn. Otherwise, the two grains are similar in composition and probably in feeding value.
