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: i: is not practicable to attempt to keep horned cattle in 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 SI. 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.
