feeding. Even if this were done, it would not rectify 

 the excessive proportion of protein. The better method 

 would be to substitute a food rich in carbo-hydrates, 

 such as maize or barley, for part of the beans accord- 

 ing to the method described in Chapter VIII., when 

 the food would be better balanced. Such a substitution, 

 using maize for part of the beans, would at average prices 

 show a diminution of cost, or alternatively, if the cost 

 were left unchanged, more food might be given daily. 



As an illustration of a too costly ration we may take 

 the following : A large stud of heavy dray-horses are fed 

 on a mixture consisting of hay 20 lbs., oats 20 lbs., 

 giving on calculation — 



The substitution of the maize-beans mixture for part of 

 the oats, as shown on p. 79, would materially lessen the 

 cost of feeding without any loss of efficiency. Other 

 suitable substitutions would be a mixture of gram and 

 maize, or gram and barley, or even brewers' grains, for 

 part of the oats. 



Before concluding this chapter, it may be advisable 

 to give a few typical rations suitable for different classes 

 of horses doing various kinds of work :
