86 ILLINOIS STATE DAIRYMEN'S ASSOCIATION 



*The investigations here reported were carried on un- 

 der the immediate direction of Professor R. S. Hulce and 

 the general supervision of the author. 



In each of the three trials two Holstein and two Guern- 

 sey calves were assigned to each lot. These two breeds 

 were used so that the results would apply to both types of 

 calves. Each calf was kept in a separate pen and an accu- 

 rate record was kept of all the feed and water consumed 

 by each animal. Live weights were taken weekly and on 

 three consecutive days at the beginning and end of the 

 experiment. 



Skim Milk Fed Calves Make Excellent Gains. 



Each year Lot I, the check lot, has been fed the sort of 

 a ration used by dairymen who have plenty of skim milk. 

 The calves were fed whole milk until 21 days of age at the 

 rate of about 1 pound of whole milk daily to each 10 pounds 

 of live weight. When a calf became 21 days of age, a week 

 to 10 days was taken to substitute skim milk gradually for 

 the whole milk. The allowance of skim milk was then 

 gradually increased to a maximum of 14 pounds. 



This lot was fed a concentrate mixture consisting of 3 

 parts by weight of ground oats, 4 of ground corn, 2 of wheat 

 bran, and 1 of linseed meal. The calves were allowed to 

 eat all of this mixture they wanted up to 5 pounds a head 

 daily. They also had all the hay they would consume 

 (clover hay in the first two trials, and mixed clover and 

 timothy hay in the third trial). Care was taken to provide 

 salt, and the calves were watered twice daily. 



In each trial these calves fed a liberal allowance of 

 skim milk made excellent gains, averaging 1.76 pounds a 

 head daily. 



Limiting the Skim Milk Allowance. 



In two of the trials other groups were fed similarly 

 except that the amount of skim milk was limited to 10 

 pounds a head daily, to represent conditions on farms where 

 the supply of skim milk for calf feeding is limited. These
