TABLE II. QUANTITY OF MILK IN PINTS PER LOT 

 PER DAY FOR 12 WEEKS. 



latter was 94'62 pints per day as against 112'31 pints per day 

 for the former. This works out to nearly 19 pints per cow 

 per day in lot I., and nearly 22 1- pints in lot II., or a difference 

 in favour of lot II. of about 3J pints per cow per day. It 

 would be unfair, however, to attribute this difference entirely 

 to the food, for, as has been already shown, the cows in lot 

 II. gave more milk on the average in the preliminary trials 

 than those in lot I. The difference between the two lots, it is 

 true, was less marked in the preliminary trials than during 

 the period of the experiment, but it is nevertheless somewhat 

 difficult to say to what extent the food is responsible for the 

 larger quantity of milk produced by lot II. here. But when 

 allowance is made for the original difference between the cows 

 composing the two lots, the above table would appear to show 

 that the additional 4 Ib. per head of concentrated food supplied 

 to lot II. gave rise to an increased yield, as compared with 

 lot I., of nearly 2 pints per cow per day. 



The total yields on the whole decreased in both lots up to 

 April 12, and a slightly further decrease occurred in lot I. up
