USING THE TABLES. 



After briefly reviewing some of the facts and principles 

 of feeding, we are now in a position to look at some tables 

 and make use of our ' ' cook book. ' ' Tables I and II are of 

 interest in showing how our common feeds vary in composi- 

 tion and digestibility. It may be mentioned at this point 

 that the figures given in these tables are the average of a 

 large number of analyses, varying from 3 to 100 or more, 

 and that they may not exactly agree with any separate 

 analysis the feeder may chance to have made, or with those 

 reported in other bulletins of this station. These are aver- 

 ages, and it is with average feeds and conditions of feeding 

 that this discussion is attempting to deal. Table III, which 

 shows the amounts of dry matter and digestible nutrients 

 in the feeds, has been derived from Tables I and II, and it 

 is the figures in this table which will be used in the follow- 

 ing computations. The matter of computing rations is not 

 at all difficult, requiring only the use of simple arithmetic, 

 including decimals and percentage. The object is to secure 

 a mixture of feeds which will correspond in the amounts 

 of dry matter and digestible nutrients which it contains, 

 to the standard which experience has found best for the 

 given purpose in view.
