Time Required After Consumption of Garlic for the Milk to 

 be Free from Garlic Flavor and Odor. 



In order to determine how long after dairy cows have 

 consumed garlic the flavor and odor produced by this plant 

 continue to be perceptible in the milk, cows were fed one- 

 half pound of garlic at various intervals before milking. 



Feeding this amount of garlic four hours before milk- 

 ing showed that the garlic flavor and odor were still pres- 

 ent to a very marked degree, 71.4 per cent of the opinions 

 rating the milk strong garlic in both flavor and odor. The 

 garlic odor was slightly more pronounced than the garlic 

 flavor, 7.2 and 21.4 per cent rating the odor very slight gar- 

 lic, and slight garlic, respectively, whereas 14.3 per cent of 

 the opinions rated the flavor in each of these groups. None 

 of the opinions rated the milk normal in either flavor or 

 odor. 



When the garlic was fed five hours before milking 

 there was a slight decrease in the intensity of the garlic 

 flavor and odor in the milk as compared with feeding four 

 hours before milking. When the garlic was fed at this time 

 7.1 per cent of the opinions rated the milk normal in both 

 flavor and odor. Of the opinions designating garlic, 28.6 

 and 64.3 per cent rated the flavor slight garlic and strong 

 garlic, respectively, while 21.5 and 71.4 per cent gave sim- 

 ilar ratings to the odor.
