With Duchess, the change to ration A resulted in a decrease 

 of 1 .47 pounds of milk per day, and an increase in fat of .33 per 

 cent. Princess gave an increase in milk of i.oi pounds, in fat 

 of .06 per cent. Maramee gave an increase of .47 pounds of 

 milk, and a decrease in fat of .07 per cent. 



Duchess (Ration A): Decrease in milk, 1.47 lbs.; increase in fat, .33 per 

 cent. 



Princess Leto (Ration A): Increase in milk, i.oi lbs.; increase in fat, .06 

 per cent. 



Maramee (Ration A): Increase in milk, .47 lbs.; decrease in fat, .07 per 

 cent. 



In period tw^o, the addition of the oils resulted in each case 

 in an increase of both milk and fat, as follows: 



Duchess (A+palm oil) : Increase in milk, 1.13 lbs.; increase in fat, .09 per 

 cent. 



Princess Leto (A+corn oil) : Increase in milk, .14 lbs. ; increase in fat, .30 

 per cent. 



Maramee (A+cotton-seed oil) : Increase in milk, .22 lbs. ; increase in fat, 

 .25 per cent. 



During the last six days of period two, in which Princess 

 Leto was again on ration A, she still further increased her 

 yield of milk .16 pounds and reduced its fat, .24 per cent. 



In period three. Duchess and Princess Leto both increased in 

 milk and decreased in fat, while Maramee decreased in both 

 milk and fat. 



Duchess (A+stearine) : Increase in milk, .38 lbs.; decrease in fat, .11 per 

 cent. 



Princess Leto (A+oleo oil) : Increase in milk, .90 lbs. ; decrease in fat, .05 

 per cent. 



Maramee (A+cocoanut oil) : Decrease in milk, 3.40 lbs. ; decrease in fat, 

 •39 P^'' cent. 



As before stated, Maramee went off feed about the middle of 

 this period, and was dropped from the experiment. This 

 explains her sharp shrinkage. 



In period four, Duchess again gained in milk and shrank in 

 fat, while Princess Leto shrank in milk and gained in fat.
