"The sows in the yearling lot, 1911-1912, were the same sows as those 

 used in the experiments of the previous year and the gilts in the 1911- 

 1912 lot were the daughters of the sows used in the previous experiment. 

 We found that the old sows ate more corn than the young ones. Toward 

 the last the fourth lot in the yearling sow experiment refused to eat the 

 alfalfa and it was practically the same as the first lot. Old sows can get 

 along on corn better than the young ones in so far as their own needs 

 are concerned. 



"The size, the vigor of the pig, the bone of the pig, and the general 

 make-up are affected more or less by the ration which the sow receives. 

 You will wonder why the oil meal lot in the gilt experiment fell down. 

 They refused to eat the oil meal during the last sixty days of pregnancy. 

 Why that is I do not know. The old sows ate the oil meal but the young 

 sows would not and as soon as they quit they began to lose. Even if a 

 sow is eating alfalfa she should have some meat meal or tankage along 

 with it. 



"As has been said, corn is lacking in calcium and in protein. Now, 

 where does the sow get these elements if she does not have them in her
