Fig. 26 shows a cross section of a corn kernel, 

 (s:) is the germ chit. 



(f. p.) is the floury portion lying just under the germ, 

 (h. p.) represents the hard, horny portion of the kernel. 

 The following table shows the comparative feeding value of the different 

 parts of the kernel: 



Per Cent Protein. I Per Cent Oil. Per Cent Ash, 



Total. 



Germ (g. ) . 



Floury portion (f. p. ). 

 Horny portion (h. p.) .

The above table shows: First, that the germ is the richest part in the 

 three most valuable feeding constituents. Second, that the white, starchy 

 portion has the lowest feeding value. From this we can see the importance 

 of selecting ears having large deep germs and containing a small amount ot 

 the floury portion.
