414. Maintenance rations for bovines. — In order to 

 express a maintenance ration for bovines in terms of hay 

 and grain, there are given in this connection several mix- 

 tures, based upon energy values in Table XXXIX, which, 

 on the basis of average composition and digestibility, 

 will furnish fairly closely the necessary protein and energy: 



To MAtNTAIN A 1,000-PoTJND AnIMAL 



12 lbs. average timothy hay. (2Z lbs. mature com silage. 



4 lbs. wheat bran. 3< 4 lbs. timothy hay. 



\ 2 lbs. wheat bran. 



(8 lbs. com stover, much water. (5 lbs. timothy hay, ripe. 

 2<6 lbs. clover hay. 4<6 lbs. clover hay. 



\.3 lbs. com-and-cob meal. (.4 lbs. com-and-cob meal. 



5. 17 lbs. good mixed hay.

These combinations are merely illustrative. Many others 

 fiu-nishing an equivalent quantity of available nutri- 

 ents may be used. Doubtless these various mixtures 

 will not show equal efficiency. Ration No. 3 would 

 probably be more satisfactory than No. 5, because of 

 greater palatableness. All such factors as the proportion 

 of grain in the mixture; the stage of growth of the fodder, 

 whether early or late cut, immature or mature; the 

 amount of moisture present, as in stover; and the com- 

 pleteness of preservation, will have an influence upon the
