THE BALANCE OF NUTRITION

a. Wheat bran, 14.28 per cent; corn meal, 42.86 per cent; old process linseed 

 meal, 42.86 per cent. 



b. Corn meal, 60 per cent ; crushed oats, 30 per cent ; old process linseed meal, 

 10 per cent. 



Some data are also available regarding the gross energy of the 

 digested nutrients of feeding stuffs. The following averages are 

 derived chiefly from Kellner's investigations. 



TABLE 26. GROSS ENERGY OF DIGESTED NUTRIENTS 



In the computation of energy balance, the factors commonly 

 used are, for body protein 5.7 Cals. per gram and for body 

 fat 9.5 Cals. per gram, although Kohler's average for the 

 former is slightly lower, viz., 5.628 Cals. (88). 



The outgo of chemical energy 



Chemical energy supplied in the feed may escape unused 

 for either of two reasons: first, the substances carrying it
