EFFECT OF FEEDING CABBAGE AND POTATOES 3 
In judging the samples, all flavors and odors which the judges 
believed to be due to feed were designated as "abnormal," and the 
varying degrees in which they were found to be abnormal were 
classified as "very slightly off, " "slightly off, " and "off. " When no 
feed flavors or odors were perceptible, the sample was rated "nor- 
mal. " It is doubtful whether the flavors and odors rated as "very 
slightly off" would be noticed by persons other than those accus- 
tomed to judging milk and cream, and the average consumer might 
have no serious objection to those samples rated by the judge as 
"slightly off." 
CHECK FEEDING 
The check samples were taken from the milk of the check cows, 
which were fed only the basic hay and grain ration. Some abnor- 
mal flavors and odors were noted in these samples but were mostly 
very slight, and were undoubtedly instances of the slight abnormal 
flavors and odors frequently encountered in milk from individual 
cows. 
Out of a total of 324 opinions on 64 check samples, 94.2 per cent 
of the opinions on flavor and 93.8 per cent of those on odor showed a 
normal condition. The greater part of the abnormal flavors and 
odors, 4.6 per cent of the opinions on both flavor and odor, were 
rated as "very slightly off." Of the opinions on flavor 1.2 per cent 
and of the opinions on odor 1.6 per cent were rated as "slightly off. " 
There were no opinions rating the samples "off" in either flavor or 
odor. (See Table 1 and fig. 1.)

FEEDING AN AVERAGE OF 14.3 POUNDS ONE HOUR BEFORE MILKING 
When the cows consumed an average of 14.3 pounds of cabbage 
(out of 15 pounds fed) one hour before milking, the flavor and odor 
of the milk were affected. A total of 271 opinions on 52 samples of 
milk produced by these cows showed that 34 per cent of the opinions 
on flavor and 30.3 per cent of those on odor rated the milk normal. 
Of the opinions designating abnormal flavors, 28 per cent rated the 
samples as very slightly off, 22.9 per cent as slightly off, and 15.1 
per cent as off. 
The abnormal odors did not vary greatly from the abnormal 
flavors, 31.7 per cent, 26.2 per cent, and 11.8 per cent rating the 
odor very slightly off, slightly off, and off, respectively. (See Table 
2 and fig. 1.)
