on. In other words, these two groups, called respectively 

 A and B, were fed with the quantity of corn and either milk 

 (A) or whey (B), with an addition of some butter- milk, which 

 represented the ordinary or normal feeding at the time on these 

 farms. Similarly on the other farms. 



In order to test in what proportion mangels could take the 

 place of corn in the feeding of pigs, two other groups of pigs, 

 called C and D, were fed with only half the quantity of corn 

 given to A and B, the other half being replaced by mangels; 

 the same quantity of milk (to C), or of whey (to D), was given 

 as that given to A and B, with the same quantity of 

 butter-milk. 



Two more groups, E and F, had the normal quantity of 

 corn, as given to A and B, and the same quantity of mangels as 

 C and D, with a corresponding deduction from the quantity of 

 milk and whey. This was done to test whether this quantity 

 of mangels could replace the quantity of milk, or of whey, 

 which in feeding value corresponds to half the normal corn 

 food. The measure of the feeding value of the food given was 

 the increase in the weight of the pigs, which was ascertained 

 after each period of ten days. 



It was first tried whether 10 Ibs. of mangels was a fair 

 equivalent for 1 Ib. of corn, or 6 Ibs. of milk, or 12 Ibs. of whey. 

 The ten days' supply of food per pig in the six groups on the 

 first mentioned farm was, in the first period of 10 days : 



In the food of groups C and D 5 Ibs. of corn were replaced 

 by 50 Ibs. of mangels. As group E and F were to have the 

 same quantity of mangels as C and D, 30 Ibs. of milk, being 

 equivalent to 5 Ibs. of corn, were deducted from the food of
