TABLE LXVIL MAINTENANCE REQUIREMENTS OF CATTLE 



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 MAINTAIN A 1,000-PouND ANIMAL 



- ( 12 Ibs. average timothy hay. /23 Ibs. mature corn silage. 

 } 4 Ibs. wheat bran. 3< 4 Ibs. timothy hay. 



V 2 Ibs. wheat bran. 



/8 Ibs. corn stover, much water. /5 Ibs. timothy hay, ripe. 

 2< 6 Ibs. clover hay. 4<J 5 Ibs. clover hay. 



(3 Ibs. corn-and-cob meal. v4 Ibs. corn-and-cob meal. 



5. 17 Ibs. good mixed hay. 



These combinations are merely illustrative. Many others 

 furnishing 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
