considerable wash water is often incorporated with it. 

 The average of all tests, however, indicates that they 

 are of quite equal feeding value. This is illustrated by 

 two trials conducted by Wilson at the South Dakota 

 Experiment Station, the average results of which are 

 shown in Table XCII.

Skim-milk and buttermilk versus other supplements. 



The feeding value of skim-milk was compared with that 

 of other standard protein supplements in two experiments 

 conducted at the Indiana Experiment Station by Skinner 

 and Cochel. The proportion of supplement fed in each 

 lot was such as to make all rations equally balanced, or 

 to give them a nutritive ratio of 1 : 7.4. There were five 

 pigs in each lot in the first experiment, and six in the 

 second. The results are shown in Table XCIII. 



In both experiments skim-milk proved to be the most 

 efficient and profitable supplement with which to balance 

 corn. In each case the gains were faster and the cost of 

 producing 100 pounds of gain cheaper than with any of
