amount of work. Tt was found that in 42 days there was an average 

 daily gain in weight of 0.42 lb. on the first ration and 0.77 lb. on the 

 second. In studying the comparative value of barley and oats, the 

 former grain was fed for 9 months to 8 horses and 2 mules, timothy 

 hay being supplied in addition to the grain. The mules did not eat 

 the ])arley with marked relisi) at any time although during the first 2 

 months, while at light work, they consumed a sufficient amount to 

 keep them in good condition. When the work was increased, they 

 could not l)e induced to eat a correspondingly increased amount of 

 barley and frequently refused it altogether. An oat ration was then 

 given them on alternate months. The oats were eaten with apparent 

 relish and on this food gains in weight were made. Two work horses 

 were fed alternately oats and l>arley, supplemented by timothy hay in 

 28 day periods for 252 days. On an average there was a daily gain of 

 0.38 lb, on oats and a loss of 0.15 lb. on barley. When malted barley 

 was compared with oats (the grains being supplemented b}^ oat hay) 

 in a test with 4 work horses, there was an average daily gain in a 49 

 day period of 0.49 lb. on oats, while on malted barley there was a loss 

 of 0.76 11). A mixture of malt and bran, 2 : 1, was then compared with 

 oats with the same horses. The test covered two periods of 4 weeks 

 each. Oat hay was supplied for coarse fodder. On the' oat ration 

 there was an average daily gain of 0.22 lb. and on the malted barley 

 and bran ration a loss of 0.80 lb. In this and other tests the amount 

 of work done by the different horses was the same. Corn and oats 

 were compared with 2 mules for 84 da3^s, one receiving a ration of oats 

 and corn, the other, of oats alone. Ear corn was used and little or 

 none of the cobs was eaten. The rations were so alternated that the 

 author believes the effects of individuality were counterbalanced. On 

 the corn and oats there was an average daily gain per mule of 0.70 lb. 

 and on the oats a loss of 0.60 lb. Tests from a previous bulletin are 

 reprinted for purposes of comparison (E. S. R., 7, p. 801). 

 The authors principal conclusions follow: 



"Brome hay gave as good results when fed to work horses as did timothy hay. 

 Barley was not equal to oats in feeding value per pound, but was nearly as good. 

 Mules did not relish l)arley. Malted barley was not so valuable for work horses as 

 oats and was not equal in value to the dry barley from which it came. Corn fed in 

 connection with oats in the proportion of 100 lbs. of corn to 125 lbs. of oats, had 

 greater value than oats; 77.5 lbs. of corn equaled 100 lbs. of oats when fed to work 

 horses."
