n the South is pretty well suppliedwith proteins, and the greatest difficulty generally comesin securing an adequate quantity of carbohydrate feeds.So far as fats, proteins and carbohydrates are concerned,it is an easy matter to pay too much attention to thebalancing rations. In certain instances, however, rationsrequire special attention to see that a sufficient quantityof ash is supplied and to see that the quality of the pro-teins as well as the quantity is adequate. Calculating of rations.—From published tables givingthe feed requirements for swine, and from tables givingthe nutrients contained in the several feeds, it is possible 148 SOUTHERN PORK PRODUCTION to calculate an accurately balanced ration for any givenherd of swine. Thus, the mathematical calculation of aration is an exact science, for it is possible to figureaccurately the feed requirements of the animal. Of course, under exceptional conditions it may be wellto calculate the rations for swine where the feeding con-

However, investi-gations have shown that under average southern condi-tions quantity of food is more often deficient than quality.Hence, the best plan is to make sure of the quantity andprovide for the quality as accurately as possible. Tofacilitate this, our swine feeds may be classified intocarbohydrate, balanced and protein feeds. In feeding, itwill suffice if sufficient quantities of feeds are given andif a carbohydrate feed is fed along with a protein feed,or vice versa, while the balanced foodstuffs may consti-tute a portion of the ration without necessity of bal-ancing. If swine rations are calculated in this crudemanner, it will be a step in the right direction and will FEEDING SWINE 149 be far superior to the blind way in which we have beenconducting our feeding in the past.
