periods it is more than maintained, showing the effect of the grains 
towards increasing the milk flow. 
Before using these figures it is necessary to offer some corrections, . 
which an inspection of our daily data will show at once to be justi- 
fiable. We note that the first influence of removal from pasture _ 
and a new food was to increase abnormally the amount eaten the 
first day, while using three days’ averages it happens that Sept. 29, a 
day of large grains consumption, is included in the next period,. 
thus increasing the amount of food eaten in Period IT, or the starvation 
period. That practically, notwithstanding the slight changes in the 
weights in groups III ond IV separately, yet practieally the two can 
be merged. We, hence, have for the purpose of our study, four 
eriods, [ and IV under hay feeding, II under starvation diet, and 
II, from Oct. 8, to Nov. 3, 27 days, as representing the effect of the 
brewers grains’. 
During the first four days of the brewers’ grain feeding, or Sept. 
26 to 29, we had a period in which a full feed of grains was con- 
sumed, and for the purpose of verifying our general conclusions, we 
can compare this period with the four preceding days on hay; thus: 
Average daily per cow:

Sept. 26-29 ...... 7.8 51.8 18.6 778 12.96 
We see then, that when the cows ate a proper quantity of the 
grains that the effect on the live weight and on the milk yield was 
excellent, and that the falling from live weight afterwards may and 
probably did, arise from the unsavory character of the food which 
acted upon the appetite of the cows to prevent a full feeding. 
We will now present the averages for the four corrected periods, 
which we shall designate hereafter as A, B, C and D.
