COMPARISON WITH OTHER RESULTS 



The results of this experiment indicate a distinct, although not great, 

 superiority per kilogram of the hominy feed over the maize meal from 

 which it was made. Before generalizing this conclusion it is obviously 

 desirable to make such comparisons as are possible with results of other 



experiments. 



AVERAGE RESULTS ON MAIZE MEAL 



Additional determinations on the influence of maize meal upon the 

 heat production, designated as experiments 179 and 220, have been 

 reported from this Institute, and the results of 12 determinations of its 

 digestibility have been averaged by Henry and Morrison (5). As Table 

 II shows, the maize meal used in the trials just described did not differ 

 materially in composition from that used in our other experiments nor 

 from the composition shown by Henry and Morrison's average. The 

 percentage digestibility of the ingredients of the samples of maize meal 

 used in our several experiments (including the results already reported 

 in Table VIII) is shown in Table XIV.
