A limited ration of bran and cotton-seed meal was given 

 in the pens having the mixed food, and the corn-meal was 

 fed to make out the full ration of as much as would be readily 

 eaten. 



The bran and cotton-seed meal were not apparently 

 relished on the start, and the amount fed was determined 

 in each case by the quantity that would be eaten with a good 

 appetite. 



An analysis of the feed was made in the laboratory, under 

 the supervision of Director Goessman, which showed the 

 composition to be as follows : — 



To prevent any possible deficiency in the ash constituents, 

 in feeding growing pigs with corn-meal alone, and to secure 

 uniformity in all conditions, aside from the differences in 

 food, leached ashes, with a few small pieces of charcoal, 

 were kept in a separate trough in each pen, to which the 

 pigs had uninterrupted access. 



The weight of each pig at the beginning of each week, the 

 feed consumed per week, and the average weight of each pig 

 for each week, will be found in Tables 1, 2, and 3. 



The amount of dry substance of food consumed per week 

 by each pig, the amount of dry substance of food required 

 to produce one pound of increase in live weight, and the 

 gain for each 100 pounds of live weight, or the gain per 

 cent, for each week, is given in Tables 4, 5, and 6.
