Profs. W. A. Henry and F. W Wolf
on The Yield and Composition of
Sow's Milk. This is a subject on
which but little previous investigation
had yet been made The ex-
periments were made at the university
farm nearly a year ago. The yield
was determined by weighing the pigs
before and after sucking. Samples
of milk were then secured and sub
jected to ,hemical analysis. Great
difficulty was experienced in securing
samples, the sOws seeming unwilling
to allow any milk to be drawn by the
attendant. In the first trials the at
tendant would attempt to milk a teal
before any milk had been drawn from
it by the pigs, but while they were
taking milk from other teats. Under
this method only very small quantities
of milk could be secured at best.
Later it was found that more milk
could be obtained with less trouble
by allowing a pig to empty an udder
in part. At this stage the young ami
NAL was pushed aside, and the attend
from the teat before the dam became
aware Of what was happening While
familiar with the attendant and not
at all afraid Of him, the sows exhibit
ed apparent surprise and repugnance
at all efforts to secure milk samples
from them
Profs. Henry and Vol found the
fnf Of u
amined to be 8.24 per cent Averages
by other chemists have been consider
ably lower, one being 674 per cent.
The average fat contents in cows milk
in 2,173 cases investigated in Mas
sachusetts was APO per cent.
The average daily yield of milk of
the four sows ranged about 5 pounds
a day. If we consider this yield an
average for good sows, and the fat con-
tent above given, 6.74 per cent, an APP
proximately correct figure, a SOW will
yield 1897 pounds of fat a day, a very
fair performance for an animal weigh
ing only one-third as much as an
average COW, especially since the milk

bules in sow's milk are of about
