stronger to boss and torment the weaker cows can be remedied, to a 

 certain degree at least, by using some sort of tie on the cows when 

 they are feeding. All cows used in the experiment were without 

 horns; it is not practicable to attempt to keep horned cattle hi an 

 open shed. 



The elimination of cows Nos. 14 and 20 from the data in Table 5 

 would change the results so that the feed cost of producing 100 

 pounds of milk in the open barn is reduced to $1.45 while that in the 

 closed barn is increased to $1.47. As regards the butterfat, the cost 

 of producing 1 pound becomes the same in both cases — 32.73 cents. 



The following prices of feeds have been used in calculating the 

 foregoing tables. They represent a fair average of the market prices, 

 for this section during the time the investigation was in progress.
