FEEDS AND FEEDING, ABRIDGED 



Tho much better, this ration is still somewhat below the standard 

 both in digestible crude protein and total digestible nutrients. 

 Eighteen lbs. of hay is all that should be fed to a horse of this weight 

 at medium work. Therefore, instead of adding clover hay to the ration, 

 we must increase the digestible crude protein and total digestible 

 nutrients by adding a small amount of some protein-rich concentrate. 

 Let us try 1 lb. of choice cottonseed meal, when we will have :

This ration meets the standard in all particulars and will give good 

 results in practice. It should not be fed blindly, however, for some 

 horses are hard and others easy keepers. Therefore, if the horse loses 

 weight on this ration, increase the allowance of corn gradually. On 

 the other hand, if he is an easy keeper and becomes too fat, cut down the 

 amount of corn. Other protein-rich feeds, such as wheat bran, dried 

 brewers' grains, or linseed meal, could be used just as satisfactorily as 

 cottonseed meal in balancing the ration, the choice depending on the 

 prices of the various feeds available.
