satisfactory, as indicated in table III, where the results with 

 the different skim-milk lots are compared. 



Limiting the Grain Ration. In the various experiments 

 with skim-milk it was noticed that the calves ate considerable 

 grain, and the question arose as to whether they did not eat 

 more than was really utilized at a profit. In order to test this 

 matter, two lots of calves, divided in the same manner as in 

 the previous experiments, were placed in the feed-lots, one lot 

 getting all the grain that it would eat up clean, and the other lot 

 receiving only three-fourths as much as the first lot. The results 

 of this test are given in table XVII.

It will be noticed that the calves getting the full grain ration 

 made the best gains, but the anxount of grain consumed per 100 

 pounds of gain is greater than the lot getting only three-fourths 

 of the full grain ration. Where grain is high and there is no 

 particular object in forcing the calves to the possible limit, the 

 grain ration may be reduced with profit.
