THE FEEDING OF ANIMALS 



397. Correcting an insufficient ration. — ^When we come 

 to compare this ration with the standard ration we find 

 it is seriously defective in two particulars: it contains 

 far too little digestible organic matter and the nutri- 

 tive 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-stufifs 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 nitroge- 

 nous food without increasing the protein supply unneces- 

 sarily. In order to avoid this, the amount of silage may 

 be raised ten poimds and still not feed an excessive quan- 

 tity. If clover hay is available, it would also be well tp 

 substitute five pounds of it for five pounds of the timo- 

 thy. If, then, we add to the ration three pounds of lin- 

 seed meal we shall approximate more nearly to our 

 standard.
