EFFECT OF FEEDING CABBAGE AND POTATOES 9 
The effect of cabbage on the flavor and odor of cream, as compared 
with milk, was less pronounced than in a previous experiment with 
turnips. In both cases, however, the abnormal flavors and odors 
were more pronounced in the cream than in the milk. When cabbage 
was fed the difference amounted to only 1.8 and 8.4 per cent in flavor 
and odor, respectively, compared with 18.5 and 22.2 per cent more 
off flavors and odors, respectively, in the cream when turnips were 
fed. This is probably accounted for by the fact that turnips contain 
an oil or other substance having an affinity for fat. 
EXPERIMENTAL FEEDING OF POTATOES 
PROCEDURE 
To determine what effect feeding potatoes has on the flavor and 
odor of milk, feeding experiments similar to those with cabbage were 
conducted. The samples were handled and judged in the same 
manner as those taken when cabbage was fed. 
cows 
Jersey and Holstein cows were used in this experiment also. The 
average weight of the Holstein cows was 1,154 pounds; the Jerseys 
averaged 876 pounds. The average daily milk production of the 
Holstein cows was 26.2 pounds, the highest individual average being 
49.9 and the lowest 12.2 pounds. The Jersey cows gave an average 
daily milk production of 15.8 pounds, the highest individual average 
being 41 pounds and the lowest 7 pounds. The average daily milk 
production of all the cows was 21.9 pounds. 
The potatoes fed, although small in size, were of good quality, 
clean, and free from rot. They were run through a root cutter before 
feeding. The same method of feeding was followed as with cabbage, 
namely : 
One group (checks) was fed no potatoes. 
One group was fed 15 pounds one hour before milking. 
One group was fed 30 pounds one hour before milking. 
One group was fed 30 pounds immediately after milking. 
The cows at times failed to consume the entire quantity of potatoes 
fed. 
In addition to potatoes, the cows were fed varying quantities of 
the same grain mixture as was given during the cabbage experiments, 
and the ration was completed by feeding as much alfalfa ha} r as the 
cows would readily consume. The average quantity of grain fed 
daily was 11.5 pounds. The largest quantity received by any cow 
was 23.5 pounds, the smallest 5.5 pounds. The alfalfa hay fed daily 
varied from 5.7 to 19.8 pounds, depending on the quantity of potatoes 
the cows were consuming. The average daily consumption was 10.8 
pounds. 
CHECK FEEDING 
Of the check samples taken from the milk produced by cows 
receiving only the basic hay-and-grain ration, there were but very few 
in which slightly abnormal flavors or odors were perceptible. A total 
of 224 opinions on 59 samples showed 96 per cent rating the milk
