Fattening Pigs in the Dry Lot

these prices for skim-milk or buttermilk, since it might 

 be possible for him to balance his com more cheaply 

 by the pm-chase of a protein supplement in some other 

 form. He can afford to pay these prices only when there 

 is no cheaper source of protein available. 



In the average ration above, 2.47 poimds of skim-milk 

 or buttermilk were fed with each pound of com. If 

 a larger proportion had been used, the value of the milk 

 would have been less than is shown by these figures. 

 On the other hand, if less than 2.47 pounds of milk had 

 been fed with each pound of com, a larger credit and a 

 higher valuation would have resulted. 



This principle is illustrated by the results of feeding 

 trials conducted by Henry ^ at the Wisconsin Experiment 

 Station. In these experiments a total of 88 pigs, averag- 

 ing a little more than 100 pounds at the beginning, were 

 used, with the results shown in the following table :

 been required to produce 100 lb. of gain.
