EFFECT OF FEEDING GREEN ALFALFA AND GREEN CORN. 5 
FEEDING 15 POUNDS ONE HOUR BEFORE MILKINC. 
Feeding 15 pounds of green alfalfa, which constitutes about half of 
a full feed, affected the flavor and odor of the milk. In a total of 378 
opinions on So samples of milk produced by cows receiving this 
amount of green alfalfa. 27 per cent and 25.4 per cent of the opinions 
rated the milk normal on flavor and odor, respectively. Opinions on 
flavors were about equally divided between slightly off and off, 29.9 
per cent rating the samples slightly off and 30.4 per cent rating them 
off, while 12.7 per cent rated them very slightly off. Off odors were 
more readily perceived than off flavors; a larger per cent of opinions 
rated the samples off in odor than in flavor; 39.9 per cent, 24.0 
cent, and 9.8 per cent rated the samples off, slightly off, and very 
slightly off, respectively. (See Table 2 and fig. 1.)

FEEDING 30 POUNDS ONE HOUR BEFORE MILKING. 
Increasing the amount of green alfalfa, fed one hour before milking, 
to 30 pounds had a more marked effect on the flavor and odor of 
milk. Out of a total of 521 opinions on 115 samples of milk pro- 
duced by cows fed this amount, only 16.1 per cent and 13.8 per cent 
of the opinions rated the milk normal on flavor and odor, respectively. 
Likewise the number of opinions rating the milk as very slightly 
off decreased somewhat as compared with feeding 15 poimds; 7.9 
per cent and 27.1 per cent rated the flavor of the milk as very slightly 
off and slightly off, respectively, while 7.1 per cent and 21.9 per cent 
gave similar ratings to the odor. 
These figures show that increasing the amount fed of green alfalfa 
intensified the off flavors and odors in the milk. By increasing the 
amount of green alfalfa from 15 to 30 pounds, the opinions rating the 
milk as off on flavor were increased from 30.4 to 48.9 per cent, and 
those rating the milk as off on odor increased from 39.9 to 57.2 per 
cent. (See Table 3 and fig. 1.)
