Dried buttermilk functions as base. The meat scrap and bone meal,, 
and digester tankage are base on account of the large amount of cal¬ 
cium of the bone. Blood is normally alkaline due to the sodium salts. 
The grain ration is 61.96 cc. acid per pound. The mashes are all alka¬ 
line or base. Those containing milk or bone, as Rations 2,3, and 4, run 
high in base elements, while the blood meal runs, only 41.21 cc. base 
which compares favorably with the two rations containing no animal 
food but protein from leguminous sources. 
If we estimate the per cent protein from peanut meal fat extracted, 
i.e., by using 7 per cent fat, as would have been the case if fat extracted 
peanut meal had been used, then the per cent protein calories will be 
28 instead of 19. This compares favorably with fat extracted soybean 
meal ration.

*Each period consists of eight weeks 
fComputed on the basis of the weight of the baby chick at hatching and at the beginning of each 
period 
tin the latter part of the third period, in all the flocks receiving animal food, egg production com¬ 
menced. As egg production commenced it is noticed that the birds consumed relatively more mash 
which has a tendency to lessen the acid balance. If not in egg production, less mash and more grain 
is consumed, which increases the acid balance.
