In judging the samples, all flavors and odors which the judges be- 
lieved 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,*' " slightl}^ off," and '' off." 
The majority of consumers might have no serious objection to 
those samples rated as " slightly off," and it is doubtful whether the 
flavors and odors rated 
as "very slightly off", ^^^^^ — - 
would be noticed by • 
persons other than those 
accustomed to judging 
milk and cream. 
'\"\nien no feed flavor 
or odor was percepti- 
ble the sample was 
rated as " normal." The 
normal samples were 
subdivided into two 
classes — O. K., and flat 
or watery. These classes 
are not shown in the 
following tables, as there 
was practically no differ- 
ence in the percentage of 
opinions rating the sam- 
ples flat or water}^ in the 
various groups, includ- 
ing the check sa^mples. 
The check samples 
were taken from the 
milk produced by cows 
receiving only the basic 
hay and grain ration.

odor of milk 
these in which 
slight 
abnormal flavors 
and odors were perceptible. A total of 296 opinions on 59 
samples showed 98 per cent rating the milk normal in flavor and 
97.6 per cent normal in odor. All of the abnormal flavors and 
odors, i. e., 2 per cent and 2.4 per cent of the opinions on flavor 
and odor, respectively, were rated as very slightly off. (See Table 1 
and fig. 1.)
