Sept. 17. 1317 Energy Values of Hominy Feed and Maize Meal 611 



average composition as shown in Henry and Morrison's compilation (Table 

 I) the digestible organic matter. Multiplying the latter by the factor 

 4.075 Calories per gram obtained in our experiments, we may compute 

 the energy values of average hominy feed to be as follows (Table XIX) :

Metabolizable ener^ 3, 542 



Energy expended in feed consumption i, 365 



Net energy value 2, 177 



The results of the foregoing comparisons agree with those of Experi- 

 ment 2 1 1 in giving a somewhat higher net energy value for hominy feed 

 than for maize meal, although the diflference is small in both cases, and 

 in the average results hardly significant (Table XX).

From the foregoing results and from the data contained in Table V it 



may be computed that the partition of the net energy of maize between 



the hominy and the total by-products included in the hominy feed is as 



follows :

CORRECTION OF EARLIER TABLES 



In three earlier publications (i, 4, 8) there has appeared a table of net 

 energy values of feeding stuffs for cattle computed in the manner pro- 

 posed by the writers (2, p. 486) from Henry and Morrison's figures for 

 digestible nutrients (5, p. 653). The foregoing results indicate that the 

 averages given in that table for maize and hominy feed require some 

 correction.
