Preparation of Feeds

of thirty-three experiments in which pigs of all ages and 

 degrees of fatness were used, do not show a sufficient 

 saving in feed by grinding to pay for the cost of the prep- 

 aration. 



Value of grinding as affected by age and finish of pigs. 



The effect of grinding corn for pigs can be interpreted 

 more accurately, however, if the results for the lighter 

 pigs are placed in one group and those from the heavier 

 animals in another. King arranged the results of the 

 eight Indiana trials in this way as shown in Table CLXIV.

 two feeding periods is shown in Table CLXV.
