The check samples were taken from the milk of the check cows, 
which were fed only the basic hay and grain ration. Some abnormal 
flavors* and odors were noted in these samples, but they were mostly 
very slight, and undoubtedly were instances of the abnormal flavors 
and odors frequentl}^ encountered in milk from individual cows. A 
total of 251 opinions on Tl samples showed 92.4 per cent rating the 
milk normal in both flavor and odor. The greater percentage of the 
abnormal flavors and odors — 7.2 per cent — were rated as very slightly 
off, while one opinion or 0.4 per cent rated a sample as slightly off. 
There were no opinions rating a sample off in either flavor or odor.

FEEDING 15 POUNDS ONE HOUR BEFORE MILKING 
When the cows consumed an average of 14.7 pounds (out of 15 
pounds fed) of green cowpeas one hour before milking, there was a 
slight effect on both the flavor and the odor of the milk produced. 
A total of 237 opinions on 67 samples of milk produced by cows con- 
suming this cjuantity of green cowpeas showed 75.5 per cent of the 
opinions rating the milk normal in both flavor and odor. In the case 
of abnormal flavors, 20.3 per cent of the opinions rated the milk very 
slightly off and 4.2 per cent slightly off. Likewise 19.8 per cent of 
the opinions rated the milk very slightly off and 4.7 per cent slightly 
off in odor. None of the opinions rated the milk off in either flavor 
or odor. (See Table 6 and Fig. 2.)
