288 The Feeding of Animals

Several authors have published tables showing the 

 amounts of digestible nutrients in given quantities of 

 our feeding stuffs, which still further shorten the work 

 that the feeder m-ust do in computing rations. 



When we come to compare this ration with the 

 standard ration we find it is seriously defective in two 

 particulars; it contains much too little digestible organic 

 matter and the nutritive ratio is too wide. 



In order to correct these faults -we must add digesti- 

 ble organic matter which contains a much larger pro- 

 portion of protein than is found in any of the materials 

 so far selected, and we must seek such a supply in part 

 at least among the highly nitrogenous feeding stuffs like 

 the oil meals and gluten meals. It is easy for one with 

 experience to see also that all the necessary additional 

 organic matter cannot be secured from a highly nitrog- 

 enous food without increasing the protein supply un- 

 necessarily. In order to avoid this, the amount of 

 silage may be raised ten pounds and still not feed an 

 excessive quantity. If clover hay is available it would 

 also be well to substitute five pounds of it for five 

 pounds of the timothy. If, then, we add to the ration 

 three pounds of linseed meal we shall approximate more 

 nearly to our standard.
