 Feeds Matter 



12 lbs. red clover hay 10 . 45 



36 lbs. corn silage 9 . 47 



2 lbs. hominy feed 1 .80 



1 lb. ground oats .91 



3 lbs. wheat mixed feed 2.70 



2 lbs. gluten feed 1.83 



Totals 27.16 2.364 18.49 



Table I does not give figures for dry matter but they can be 

 obtained by subtracting the figures for water from 100. To con- 

 struct the above table we thus multiplied the pounds of each feed 

 by the appropriate figure for analysis from Table I, remembering 

 that we had to point off two places. For example, the computation 

 for clover hay was as follows: 



12 X (100— 12.9) = 10.45 lbs. dry matter 



12 X 7 . 6 = .912 lbs. digestible protein 



12X50.9 = 6.11 lbs. T.D.N. 



It takes some time to construct the table so as to have it come 

 out the way we want it, but it goes much easier after a little prac- 

 tice. It is easy to get the dry matter to come in the range specified. 

 We try to come within .2 pounds for the digestible protein and 

 .5 pounds for the total digestible nutrients. The grain mixture 

 we have selected would cost 16.2 cents for the eight pounds for 

 a day's feeding, or $40.40 per ton. 



We like to have some oil meal in the dairy ration where it is 

 not too expensive. Here is a mixture containing it which would 

 meet the requirements:
