378 The Feeding of Animals 



No definite rations are suggested for more severe 

 labor. The amount of food must simply be increased 

 with the amount of work performed. Any increase 

 should apply to the grain and not to the hay, the pro- 

 portions of the several feeding stuifs in the grain 

 ration to remain the same in the larger quantity. It 

 is well understood, of course, that a ration should 

 increase proportionately faster than the amount of 

 work done, and that an old animal generally demands 

 higher feeding than does a young one. The condition 

 of the road, the intensity of the effort and other cir- 

 cumstances also modify the needs of the working horse, 

 so that the feeder is always called upon to exercise 

 the trained judgment which comes from experience. 

 No working animal can be fed successfully by mechan- 

 ical rules.
