282 BEGINNINGS IN ANIMAL HUSBANDRY 



The second step in calculating the ration will be to find 

 out how much dry matter, and digestible protein, carbo- 

 hydrates, and fat, occur in each of the amounts of the dif- 

 ferent feeds, and write these figures in the proper blank 

 places in the table. Turning now to page 387, in the back of 

 the book, you will find Table A, showing the amount of 

 dry matter and digestible nutrients in 100 pounds of a 

 number of different feeding stuffs. The composition of each 

 of those to be fed this cow can be easily found. Let us take 

 red clover hay for our first calculation. 



Red Clover Hay 



DRY MATTER PROTEIN CARBOHYDRATES FAT 

 100 Ibs. contain 84.7 Ibs. 7.1 Ibs. 37.8 Ibs. 1.8 Ib. 

 Then 10 Ibs. contain 8.47 Ibs. 0.71 Ibs. 3.78 Ibs. 0.18 Ib. 



Taking corn silage next, we find that 



DRY MATTER PROTEIN CARBOHYDRATES FAT 

 100 Ibs. contain 26.4 Ibs. 1.4 Ibs. 14.2 Ibs. 0.7 Ib. 

 Then 30 Ibs. contain 7.92 Ibs. 0.42 Ibs. 4.26 Ibs. 0.21 Ib. 



Corn and Cob Meal 



DRY MATTER PROTEIN CARBOHYDRATES FAT 

 100 Ibs. contain 84.9 Ibs. 4.4 Ibs. 60. Ibs. 2.9 Ibs. 

 Then 5 Ibs. contain 4.24 Ibs. 0.22 Ibs. 3.0 Ibs. 0.145 Ib. 



Coming last to bran t we find that 



DRY MATTER PROTEIN CARBOHYDRATES FAT 

 100 Ibs. contain 88.1 Ibs. 11.9 Ibs. 42.0 Ibs. 2.5 Ibs. 

 Then 3 Ibs. contain 2.64 Ibs. 0.36 Ibs. 1.26 Ibs. 0.075 Ib. 



If we have copied these figures as soon as worked out, 

 into the blank places fixed for them in the table on page 281, 

 then we shall have the following, after we have added 

 up the totals:
