192 ILLINOIS STATE DAIRYMEN'S ASSOCIATION 



received low grade dried skim milk powder. As only one 

 experiment on each of these rations has been carried on 

 and since the trials are still in progress, it is too early to 

 decide whether the use of these feeds will either increase 

 the rate of growth of the calves or reduce thej cost of feed- 

 ing them. 



This year one lot is also being fed only ground corn 

 as the concentrate with a liberal amount of skim milk, hay, 

 water, and salt. This lot is being fed in comparison with 

 Lot 1, which receives the concentrate mixture of corn, oats, 

 bran, and linseed meal. Skim milk is very rich in protein. 

 Therefore it is doubtful whether any better results will be 

 secured when protein-rich feeds like wheat bran and lin- 

 seed meal are included in the concentrate mixture for calves 

 fed plenty of skim milk than where only corn or other grain 

 is fed. In the trial now in progress the lot fed corn as the 

 only concentrate has thus far done just about as well as 

 the calves fed the purchased protein-rich feeds as part of 

 their concentrate mixture.
