Feeds and Feeding. 



by immediate feeding. When soft corn containing 35 per ct. of 

 water was fed to cattle at the Iowa Station, 1 it was found that a Ib. 

 of dry matter in such corn equaled a Ib. of dry matter in hard 

 corn, and that the cattle fed soft corn finished as well as those 

 fed hard corn. (524, 843) 



155. The corn kernel. Hopkins of the Illinois Station 2 separated 

 the water-free kernels of an ear of average dent corn into their 

 several parts, and analyzed each part with the results given be- 

 low : 



Location of nutrients in the water-free corn kernel. 



It is shown that in 100 Ibs. of water-free corn the hulls and tip 

 caps together amounted to 7.39 Ibs., the hornlike layer of gluten 

 just under the skin 8.51 Ibs., and the flinty, hornlike starch at the 

 sides and base of the kernel 47.08 Ibs., or nearly one-half of the 

 total weight. In each 100 Ibs. of kernels the soft, floury starch 

 in the middle portion of the kernel formed 25.49 Ibs. and the germ 

 11.53 Ibs. The last 4 columns of the table show the number of 

 pounds of each nutrient contained in each of the several parts of 

 100 Ibs. of water-free corn. It is seen that the hull and tip cap 

 are largely carbohydrates, while the germ is heavily charged with 

 crude protein and oil. 



It is shown that 100 Ibs. of water-free corn contains over 11 Ibs. 

 of crude protein. It further contains over 82 Ibs. of carbohydrates, 

 of which about 80 Ibs. is starch, and the remainder, something over 

 2 Ibs., comprises the fiber of the hulls and of the cell walls inclosing 

 the starch grains. Of oil there is nearly 5 Ibs., and of mineral 

 matter only about 1.5 Ibs. Thus it is shown that the corn grain is 

 fair in crude protein, rather low in ash, rich in oil, and extremely 

 rich in starch. It is because of the abundance of these latter two
