FIFTIETH ANNUAL CONVENTION 181 



abnormal results due to the milk of an individual animal. 

 The feeding of turnips was then resumed. 



Milk Samples. 



Samples were taken from the milk of each cow at the 

 time of milking, given a key number and cooled, but not 

 aerated. The samples were judged for flavor and odor by 

 experienced judges, who had no knowledge of the key. An 

 "opinion, " as this term is used in the following pages, de- 

 notes the decision of the judge in regard to one sample. 



Using the terd "off" to signify flavors and odors which 

 the judges believed to be due to turnips, the following 

 clasification was used: Normal; very slightly off; slightly 

 off; off. When no off flavor or odor was perceptible, the 

 sample was rated normal; and when an off flavor or odor 

 was perceived the sample was rated according to the de- 

 gree which the judge considered it to be off. The average 

 consumer might have no serious objection to those samples 

 rated as "slightly off;" and it is doubtful whether the fla- 

 vors and odors rated as "very slightly off" would be noticed 

 by persons other than those accustomed to judging milk 

 and cream., 



The Experimental Feeding. 

 Check Samples. 



The check samples were taken from the milk of the 

 check sows, which were fed only the basic hay and grain 

 ration. A few off flavors and odors were noted in these 

 samples, but they were very slight, and undoubtedly were 

 instances of the slightly off flavors and odors which are 

 frequently found in milk from individual cows. 



Out of a total of 285 opinions obtained on 50 check 

 samples, 97.5 per cent of the opinions on flavor and 94 per 

 cent of those on odor showed a normal condition. All the 

 off flavors and odors, that is, 2.5 per cent of the opinions on 

 flavor and 6 per cent of those on odor, were rated as very 

 slightly off.
