THE NUTRITION OF THE HORSE. 



261 



During this period these horses were working eight to nine hours daily 

 for 5^ days each week, doing plowing, harrowing and similar farm work. 

 They maintained their live weight, but were^ not in as good flesh as was 

 desired. 



Ration III. 



On June 24 the hay was increased to 18 pounds daily, and so continued 

 until July 15, for the reason that they acted rather hungry, and it was 

 thought a little more bulk would render them more contented. 



The work during the above time was of about the same character, but 

 on the whole not as difficult as during June. The live weight appeared to 

 be maintained, but apparently did not increase. 



Ration IV. 

 On July 15 the grain mixture was increased to 20 pounds for Tom and 

 19 pounds for Joe, in addition to the 18 pounds of hay, and so maintained 

 until September 1. 



Weights. 



Dm-ing the above period Tom appeared stationary and Joe increased 

 about 25 pounds in weight. Tom is a long-bodied, long-legged horse and 

 not as compact of build as is Joe. In spite of the fact that the live weight 

 was not substantially increased, the horses appeared in better condition 

 than in the early summer. The horses were quite fully employed during 

 August in harrowing, plowing and drawing manure. 



The estimated pounds of nutrients and therms of energy contained in 

 the daily ration on the basis of 1,400 pounds live weight follow: —
