HFFECT OF SILAGE ON ACIDITY OF MILK. I5!I 
As may be seen from these figures, there was apparently a 
slight increase in acidity when the cows were ‘‘taken off’’ a 
silage ration, but the difference is so small that it may proba- 
bly be attributed to chance variations. There is a much more 
noticeable difference between individual cows, as is shown by 
the following analyses, all on silage rations: ‘‘ Brownie,’’ 
average of six analyses, 0.19 per cent.; ‘‘ Molly 2d,’’ average 
of six analyses, 0.185 per cent.; ‘‘ Naomi’s Beauty,’’ average of 
seven analyses, 0.11 per cent., and ‘‘ Kthel’s Fancy,”’ average 
of twelve analyses, 0.175 per cent. The mixed milk of the 
herd of 25 cows on grass (May 25th to 27th) showed as an 
average of six analyses 0.175 per cent. of acidity.
