258 MASS. EXPERIMENT STATION BULLETIN 188. 



It seemed evident that for the work performed the horses were receiving 

 sufficient nutrients to keep them in normal condition, although they did 

 not materially add to their weight. 



Ration II. 

 On June 19 the ration was modified slightly by replacing 2 pounds of 

 the oats with 2 pounds of the brewers' grains, thus increasing the protein 

 slightly, while the total nutrients received were nearly the same.

During this period there seemed to be a slight loss in weight. Whether 

 this was due to the warm weather or to the modification of the ration is 

 not clear.

On July 17 the horses were put back on to Ration I and continued 

 until August 14>
