286 The Feeding of Animals 



have been found for feeding stuffs in the condition of 

 those which are to be fed. If the hay is from mature 

 grass use the composition percentages and digestion 

 coefficients given for such hay; if the silage is from 

 mature corn, pursue a similar course in this case, and 

 so on. Difficulty will be met in always finding suit- 

 able figures, because without question there has been 

 a failure to properly classify tables of composition and 

 digestibility on the basis of the character of the ma- 

 terials. 



The assumed ration which we wish to find out 

 about consists of 



Ibs. Ibs. 



Late cut timothy hay. . 10 Hominy chops 2 



Corn silage 25 Winter wheat bran. . . 3 



The averages for composition and digestibility, 

 which are as likely as any to represent these and other 

 materials, are the following:

Clover hay, average quality 15.3 6.2 12.3 24.8 38.1 3.3 58. 54. 64. 55. 



Corn silage 79.1 1.4 1.7 6. 11. .8 56. 70. 76. 82.

Wheat bran 11.9 5.8 10.4 9. 53.9 4. 78. 29. 69. 68. 



Linseed meal, N. P 10.1 5.8 33.2 9.5 38.4 3. 85. 80. 86. 97. 



The first step in the calculation is to find out what 

 percentages of digestible material the components of 

 pur proposed ration contain, and we shall obtain these
