meal, and cotton seed meal (in small amounts only, mixed with 

 other grain feeds). 



Dairy products form a most important group of swine feeds in 

 dairy sections, and are used extensively as feeds supplementary to 

 Indian corn. The results obtained in feeding skim milk and corn 

 to pigs depend, to a large extent, on the proportions in which the 

 two feeds are given. Skim milk alone will produce very unsatis- 

 factory results in feeding pigs, 9 and more than five or six pounds 

 of skim milk per pound of corn is also likely to give poor returns. 

 The ratio of skim milk to grain to be fed will depend upon the 

 relative price of the two feeds and on the age of the animals; fed 

 to pigs shortly after weaning, larger proportions of milk will give

better results than with older animals. The results of a large num- 

 ber of trials at the Wisconsin station and elsewhere showed that a 

 ration of 3 to 1 will give most economical results in gain of live 

 weight. Fed in the ratio of 3 pounds of milk for each pound of 

 corn meal, Henry found 10 that 327 pounds of milk were required 

 to save 100 pounds of meal; in the ratio of 35 : 1 it required 446 

 pounds; 5-7: 1, 574 pounds, and 7-9: 1, 552 pounds, and, on the 

 average for all trials, 475 pounds (p. 207). 



Corn is the best supplemental grain to feed with skim milk or 

 buttermilk for growing pigs; with whey, on the other hand, wheat 

 shorts, pea meal, or linseed meal as a part of the grain ration is to 

 be preferred, being mixed with corn in increasing proportions of the 

 latter as the animals approach maturity. 11 Trials made in this
