] Of various preseryatives in milk. The
\ bulletin says:
"The study of the influence of preser-
vatives upon the food value of milk
was undertaken by this station be- |
cause of the extensive and growing use
4 which is being made of various pre-
servatives in many parts of the coun-
try; and particularly in milk supplied
to the Baltimore and Washington
trade.
'The plan adopted in the expert
ments which have been conducted here
was to study the effect of the principal
personalities upon the digestibility of
milk. 1t would have been far prefer
able to have used young children in
such work; but this was impossible
for obvious reasons; and animals had
to be resorted to. Young calves were
selected for the experiments as it
seemed probable that they would be
more susceptible to the influence of the
!, personalities than any other animals
: available and then, too, they are easily
T fed and controlled. In using calves for
this work it was, of course with full
appreciation that they were not so SEN
!. sitive in all respects as human be-
ing, and also with a full understanding
that there was wide difference in
some respects in their digestive Or
, gans as compared to a mans. Never
: theless it was assumed that preser-
vative which would prove to be harm
full or which would make milk less dl-
gestible with calf would certainly be
unfit for use in connection with human
beings and particularly for infants.
. Again it was considered at the outset
s that in case a preservatiye showed no
4 effect with calf, it would not neces-
sarily prove that said preservative
/ could be added to milk to be used by
children without causing them harm.
