BREEDS OF SWINE 457 



Linseed Oilmeal. The rations of linseed oilmeal and corn meal 

 in proportion of 1 to 5 were eaten in larger quantity than any other 

 feeds tested, and made more pork, with smaller expenditure of feed 

 than any other ration involved. Estimating the cost of linseed oil- 

 meal at $30 per ton, corn at 30 cents per bushel, grinding at 10 cents 

 per hundredweight, and wheat middlings at $18 per ton the cost of 

 pork made from the oilmeal rations averaged 11.3 per cent less than 

 from the rations of corn meal and wheat middlings. The average 

 cost per 100 pounds with the oilmeal rations was $3.23, and with the 

 middlings rations, $3.60, or a difference of 37 cents per 100 pounds 

 of pork in favor of the oilmeal rations. In order to make pork from 

 corn meal and wheat middlings as cheaply as from the above men- 

 tioned ration of corn meal and linseed oilmeal the middlings would 

 have to be bought at prices ranging from $14.70 to $15 per ton in 

 the various lots. Middlings are usually more expensive, and linseed 

 oilmeal is usually less so than as here figured. 



With corn at 25 cents per bushel it would be an even thing so 

 far as cost of gain is concerned whether one would feed it alone or 

 with oilmeal at $30 per ton as in lot 15 ; with corn at 29 cents per 

 bushel there would be no saving or loss from the feeding of mid- 

 dlings with corn as in lot 14, allowing in each case ten pounds of 

 pork per bushel of corn fed alone. 



There must also be considered the fact of the greater rapidity of 

 the gains produced by the linseed oilmeal ration. With both rapidity 

 and economy of production in its favor it would seem that this were 

 the better feed with which to supplement corn for fattening hogs. 

 The oilmeal ration was so much more palatable than the middling 

 rations that much more of it was eaten daily. The pigs receiving this 

 feed, always ate heartily and consistently even during the coldest 

 weather and evinced a fondness for their food that was not noticeable 

 in any other case. (Mo. B. 67.) 



Soy Bean Meal. Corn meal and soy bean meal proved to be a 

 more efficient ration in the tests reported than corn meal and linseed 

 meal, both as regards the rate and the cost of gains. (Ind. B. 126.) 

 Soy beans made an excellent pig feed mixed with corn in the propor- 

 tion of 1 :2. Being rich in protein it is recommended as an espe- 

 cially efficient addition to the ration when corn composes the larger 

 part. (Ky. B. 101.) Soy fbean meal has proven to be equally as 

 efficient as linseed meal in all of the tests conducted at the Station. 

 (Ind. B. 137.) 



In the pn.^t, when the cowpea and the soy bean sold at cheap 

 prices, some fanners used them in large amounts in hog-feeding 

 operations. But they have advanced in price within the last few 

 years and at the present time must be used in limited amounts. 

 When they arc valued at $1.50 a bushel neither one can be used 

 freely. (F. B. 411.) 



Soy beans may be grown in the Corn Belt and used with profit 

 in pork production, though the supply of beans on the market is 

 sufficient only to satisfy the demands for seed, at seed prices. (0. 

 B. 213.)
