The two lots of pigs were quite uniform in size and qualit}', being 

 from the same litter. The age of the pigs at the beginning was five 

 months. The feeding was continued for 81 days, with the rations 

 given below. 



Lot 3. 



4 lbs. clear meal, 

 3 " potatoes, 

 Milk. 



Lot 4 



5 lbs corn-and-cub meal, 



3 " potatoes.

This experiment would have been more satisfactory if the feeding 

 had been continued during a second period with the rations changed 

 about. So nearly alike were the two lots of pigs, however, that it does 

 not seem possible that the presence of a pound of ground cobs in the 

 food of Lot 4 could have added greatly to the nutritive value of the 

 ration without the effect being seen in increasing their growth over 

 that made b}' Lot 3. 



It is proper to state that the corn-and-cob meal was ground fine. 



Experiment with Raw and Boiled Potatoes. 



It has been shown on previous pages that the composition of pota- 

 toes is only slightly changed by boiling. This being the case, it is 

 difficult to understand ho-w their nutritive effect would be mate- 

 rialh' changed by cooking in this way. The Station has made this 

 matter the subject of an experiment, with somewhat unsatisfactory 

 results, owing to the fact that in the second period of feeding one lot 

 of pigs did not seem to relish their ration. 



As in the two preceding feeding trials, the experimental animals 

 consisted of six pigs which were selected from the same litter. They
