The weights were well maintained, indicating that for the work per- 

 formed sufficient nutriment was being supplied. The work was rather 

 irregular during this period, and may be considered as light. 



The combination of hay, corn and oats evidently was sufficient in total 

 digestible nutrients, but rather deficient in protein, according to Grandeau, 

 for horses doing moderate work. The therms of energy were noticeably 

 below the standard. The ration conformed more closely to that set by 

 Lavalard, who accepts one with less protein and a wider nutritive ratio 

 than other investigators. It is well known that horses keep in good con- 

 dition and do satisfactory work on rations composed of hay, corn and oats. 

 It seems probable, therefore, that only in case of quite hard work is it 

 desirable to increase the protein requirement above the amount furnished 

 by such a combination. Less corn and more oats, i.e., rather more pro- 

 tein and less starch, or a somewhat narrower ration, is desirable in the 

 warm summer months. 



While recognizing the large number of horses in the Kansas experiment 

 and the satisfactory results secured, on the basis of our own observations 

 and the accepted feeding standards it seems to the writer that the amounts 

 of the several feeds are not likely to be sufficient, nor the combination
