Calculating Rations for Farm Animals General requirements of satisfactory rations.—The various feeding standards make recommendations only in regard to the amounts of dry matter, of the various nutrients, and, in the case of the Kellner and Armsby standards, of the net energy which the ration should supply. However, the following highly important factors should also be taken into account in computing rations for farm animals. Suitability of feeds.—The feeds selected for any animal should be such that they will not injure its health or the quality of the product yielded. Feeds which are suited to one class of farm animals may. Fig. 26.—A "Balanced" Ration Which Is Unsatisfactory and Expensive This ration of 20 lbs. timothy hay, 2 lbs. corn meal, 5 lbs. wheat bran, and 2 lbs. linseed meal, meets the standards for a 900-lb. dairy cow yielding 20 lbs. of 5 per ct. milk. However, the timothy hay is not palatable, and the ration is not only unsatisfactory but expensive. Cost 26 cents. (From Humphrey, Wis- consin Station.) not be adapted to others. Again, a given feed may give satisfactory results only when combined with certain other feeds. A few examples of such conditions are furnished in the following: Cottonseed meal in moderate amount is an excellent feed for cattle, sheep, and horses, yet it is frequently poisonous to pigs. Timothy hay, the standard roughage for horses, is unsatisfactory for dairy cows, and may cause serious trouble with sheep on account of its constipating effect. Feed- ing cows a heavy allowance of ground soybeans produces unduly soft butter, while an excess of cocoanut meal makes the butter too hard. It is often highly beneficial to add wheat bran or linseed meal to the ration because of their slig
