nitrogenous grains, chiefly barley, have been added 

 to the grain ration for the purpose of improving the 

 quality of the pork produced and preventing the 

 bacon from being soft. It is not only grains, how- 

 ever, which are fed with corn meal to balance it 

 and prevent the bad effects of an exclusive corn meal 

 ration, but skim milk must also be mentioned 

 among the supplemental feeds to be fed with corn. 

 In Missouri the recommendation is made that alfalfa 

 and clover hay and skim milk are to be considered 

 the best feeds to use with corn in completing the 

 pig's ration. In New Hampshire it was found that 

 when four pounds of skim milk were fed with each 

 pound of corn meal excellent results were obtained 

 in pig production. Pigs which received this ration 

 were the best feeders and made the best gains and 

 the cost per pound of gain was two cents less than 

 with a mixture of corn meal and middlings. In 

 Missouri various grain feeds have been found valu- 

 able as supplemental to corn in raising pjigs. In 

 this list we may mention linseed meal, middlings, 

 bran, oats, gluten feed, and bone meal. Among these 

 feeds linseed meal gave the most efficient results 

 and the greatest profit. Bone meal and other ani- 

 mal foods, however, especially skim milk, are per- 

 haps better utilized by pigs than by any other of 

 our domestic animals. In one set of experiments 

 in which various other grains were used to replace 

 part of the corn meal in rations for pigs it was found 

 that one ton of linseed meal was equal to seven 

 thousand seven hundred pounds of corn, while a 

 ton of bran was equal to three thousand two hun- 

 dred pounds of corn.

 which are necessary additions to the ration in 

 securing the greatest effectiveness from corn meal,
