In Experiment IV the alfalfa ration apparently increased the yield of 

 milk 5.2 per cent., while in Experiment V the yield was the same on each 

 ration. The total yield for both experiments was 5,407.6 pounds on the 

 rowen, and 5,568.4 pounds on the alfalfa, or an increase of 3 per cent, in 

 favor of the alfalfa. The rowen ration produced a total yield of 760.97 

 pounds of solids as against 767.64 pounds for the alfalfa; the total yield 

 of fat was 281.74 pounds on the rowen ration, and 278.73 pounds on the 

 alfalfa; the yield of nitrogen was 29.94 pounds on the rowen ration, and 

 31.38 pounds on the alfalfa. 



The following table shows the amount of milk and milk ingredients pro- 

 duced by 100 pounds of dry matter derived from each of the two rations: —

In case of the volume of milk, and to a less degree in case of the total 

 solids, the jdelds were rather in favor of the alfalfa ration. The fat per- 

 centage, on the other hand, did not keep pace with the increase in the 

 milk yield. Note (Table XXVII) that in Experiment IV, with the rowen 

 ration, the percentage was 5.1 as against 4.82 for the alfalfa ration; and 

 in Experiment V, 5.35 for the rowen ration as against 5.17 for the alfalfa 

 ration. The per cent, of solids not fat was substantially the same in each
