TABLE XIII. AVERAGE PERCENTAGE OF SOLIDS NOT FAT 

 IN MILK FOR 12 WEEKS. 



General average for day's milk : Lot I., 8 '8 ; Lot II., 8 '8.

of cows, viz., 8*8 per cent. In calculating the general average, 

 allowance is of course made, as with the butter-fat, for the 

 difference in the average quantity of milk, morning, noon and 

 evening. The morning milk was slightly lower, on the average, 

 in lot II. than in lot I., but in both cases the milk was well 

 above the standard, and the difference between the two lots 

 is 'so small as to be negligible. 



The effect of the rations on the average live-weight of 

 the cows, which were weighed monthly during the period of 

 the experiment, is shown in Table XI Y. 



The results show an average decrease of 13 Ib. per cow in 

 lot I., and an average gain of 25 Ib. in lot II. This loss of 

 weight in lot I. was largely due to one cow (No. 60) which, 

 owing to some unknown cause, lost 91 Ib. during the first 

 month of the experiment. The same cow, during the second
