475. Whole milk v. skim milk. At the Utah Station 1 Linfield 

 fed calves averaging about 70 Ibs. whole milk, while others given 

 whole milk at first were gradually changed to skim milk. The feed 

 for 100 Ibs. of gain is shown in the table: 



Feeding calves whole milk and skim milk. 



It will be seen that the calves getting whole milk required 950 

 Ibs. of milk, containing 37 Ibs. of butter-fat, for 100 Ibs. of increase, 

 live weight. These calves yielded 65 per ct. of dressed carcass. Those 

 fed at first whole milk and later skim milk required 360 Ibs. of whole, 

 milk and 830 of skim milk for 100 Ibs. of gain, and dressed but 58 per 

 ct. Linfield states that skim milk fed to calves gave fully as large 

 financial returns as when fed to pigs. 



476. Pasteurized skim milk. In two trials at the Ontario Experi- 

 mental Station 2 Dean found that calves fed pasteurized skim milk 

 (heated to 160 F.) made somewhat better gains than others fed un- 

 pasteurized skim milk. At the Kansas Station 3 Otis found practically 

 no difference in the feeding value of pasteurized creamery skim milk 

 and that fed directly from the hand separator, except that the pas-
