Show FATTENING HOGS ON CORN ALONE Many Farmers Still Making Big Mistake With Swine. Too many Minnesota farmers still make the mistake of trying to fatten I their hogs on corn alone, says H. G. Zavoral, swine specialist of the Minnesota Min-nesota agricultural extension division, university farm, St. Paul. Hogs that are fed an all-corn ration do uot get sufficient protein either to keep them gaining at the maximum rate, or to make the most economical gains from the standpoint of feed cost. The economy of supplying sufficient protein in the fattening ration for hogs has been proven repeatedly, not only in the experience of farmers, but also in trials conducted at varjous experiment ex-periment stations. At the Minnesota agricultural experiment station, trials carried on in three successive years showed that hogs fed corn alone made average daily gains of only .90 pounds, and consumed $5.20 worth of feed for each 100 pounds of gain, while hogs fed corn and buttermilk gained two pounds a day at a cost of $4.12 per 100 pounds. A third group of hogs fed corn and tankage made slightly lower daily gains than those fed corn and buttermilk, but at a lower cost. This latter group gained 1.7 pounds per day, and put on weight at a cost of $4.09 per 100 pounds. Mr. Zavoral recommends that for hogs on corn without skim milk or buttermilk, or with Insufficient quantities quanti-ties of these, tankage or a mixture of tankage and oil meal be self-fed. Hogs do better when fed both plant and animal an-imal protein, the ratio being about two-thirds tankage and one-third oil meal. This mixture is also somewhat cheaper than tankage alone. |
