EFFECT OF GREEX EYE AND GEEEN COWPEAS ON FLAVOR OF MILK 5 
FEEDING 30 POUNDS IMMEDIATELY AFTER MILKING 
There was but little effect on either the flavor or odor of the milk 
produced at the next milking when cows consumed 30 pounds of 
green rye immediately after the previous milking. A total of 299 
opinions on 60 samples of milk, produced by cows consuming this 
quantity of green rye immediately after milking, showed 92.3 per 
cent of the opinions rating the' milk normal in flavor, and 91.6 per 
cent normal in odor. In the case of abnormal flavors, 7 jDer cent 
of the opinions rated the milk very slightly off and 0.7 per cent 
slightly off. Likewise, 7.4 per cent of the opinions rated the milk 
very slightly off and 1 j)er cent slightly off in odor. None of the 
oj^inions rated the milk off in either flavor or odor. (See Table 4 
and fig. 1.)

EXPERIMKNTAL FEEDING OF GREEN COWPEAS 
PROCEDURE 
In order to determine what effect feeding green cowpeas has on the 
flavor and odor of milk, feeding experiments similar to those with 
green rye were conducted. The samples were handled and judged 
in the same manner as those taken when green rye was fed. 
The investigation was conducted with 7 Holstein and 13 Jersey 
cows. The aA'erage weight of the Holstein cows was 1,169 pounds, 
and of the Jerseys 923 pounds. The average daily milk production 
of the Holstein cows was 22.5 pounds, the highest individual average 
being 31.7 poimds and the lowest 9.4 pounds. The Jersey cows gave 
an average daily milk production of 16.3 pounds, the highest individ- 
ual average being 25.3 pounds and the lowest 8.5 pounds. The aver- 
age daily milk production of ail the cows was 18.4 pounds. 
The cowpeas were fed soon after blooming and before the seed had 
formed. In addition to green cowpeas, the cows were fed varying 
quantities of the same grain mixture as was given during the green- 
rye experiments, and the ration was completed by feeding what al- 
falfa hay the cows would readily consume. The average quantity 
of grain fed daily was 8.3 pounds. The largest quantity received 
by any cow was 15 pounds, the smallest 3 pounds. The quantity of 
alfalfa hay fed daily varied from 8 to 18.8 pounds, depending upon 
the quantity of green cowpeas the cows were receiving. The average 
daily quantity of alfalia hay consumed w^as 12.6 pounds.
