of a large number of trials at the Wisconsin station and else- 

 where showed that a ration of 3 to 1 will give most economical 

 results in gain of live weight. Fed in the ratio of 1 to 3 pounds 

 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 3-5 : 1, 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

country and abroad have shown that 1000 pounds of ordinary whey, 

 when fed with grain feed, such as corn meal and barley or shorts, 

 will save 100 pounds of grain in feeding fattening pigs, and that 

 two pounds of whey are worth about as much as one pound of 

 skim milk or buttermilk in feeding swine (p. 209). Canadian 

 experiments have shown no appreciable difference in the feeding 

 value of sweet and sour whey, but whey run through a separator or 

 from separator skim milk is worth only 75 to 80 per cent as much as 

 common whey obtained in the manufacture of American cheddar 

 cheese. 12
