These growing mashes are all fed with scratch grains consisting of such grains as corn, wheat, barley, and oats. Corn, wheat, or barley may be used as the only scratch grain except with growing mash No. 4, which should contain from 50 to 75 percent of oats. A good grain mixture may be made of 40 parts of corn, 40 parts of wheat, and 20 parts of oats. Mashes 1 and 2 are for flocks having access to a good green range. In mash No. 2 soybean oil meal, which has proved to be a good source of protein and is also good for fattening, is substituted for meat scrap. Mash No. 3 is a more complete ration and is advised for all conditions where the turkeys do not have an abundance of growing green feed. Other combinations of grains and byproducts may be used successfully, the exact selection depending largely on availability and cost of feeds. It is best to use at least two grains, and preferably three or four, in the ration. Corn is the grain most commonly used in feeding turkeys. Not more than 60 percent of the entire growing ration should consist of oats or barley or a combination of the two. Yellow corn tends to produce a deep-yellow skin color while white corn, barley, and wheat produce turkeys with light-colored skins. If the birds have all the milk they will drink along with whole grains, they will consume enough milk to make good growth, if no water is fed. A mixture of 30 percent of corn, 30 percent of oats, 20 percent of wheat, and 20 percent of barley is satisfactory; so is a free choice of several grains. However, the whole-grain and liquid-milk method works well only when the birds are on a good, green range and is practical to use only when milk products are cheap. Some loss from pendulous crops is to be expected when liquid milk is consumed liberally and this is one of the chief objections to its use. The milk receptacles should be set on a wire screen and covered to protect them from the weather and from contamination with droppings. Sanitation is especially important when milk is used. GENERAL SUGGESTIONS FOR FEEDING Feed should be kept before the birds constantly from hatching to market age. During the first 6 weeks feed starting mash. During the seventh and eighth weeks feed a mixture of equal parts of the starting and growing mashes. From 9 to 12 weeks feed the growing mash. From 13 weeks to marketing feed growing mash and scratch grain. No scratch grain is fed during the first 12 weeks. If a change is made from mash to the whole-grain and liquid-milk method, cut down the mash gradually until the poults learn to drink the milk and to eat the whole grain freely.
