under open-shed conditions the cows
had more freedom, az they could lie
down and get up with ease and could
select clean place on which to lie
whenever they chose. Furthermore,
they had access to an abundant sup

doubtless would be an important fac

sirable as a source of COW comfort.
Data collected by the department
of agriculture shows that in the In
stance of 81 cows which were kept
under the two systems, Is animals pro-
duced more milk and butterfat when
kept In the open shed, while six cows
showed q higher production when
maintained In the closed barn. The
total production while In the open
shed was 34,630.9 pounds Of milk con.
tanning f,535.15 pounds of butterfat,
and that In the closed barn was 81
1857 pounds Of milk containing l.
1874 pounds Of butterfat. Accord

there was total increase for the
period considered. about eighty days,
of 2,732.2 pounds of milk aad 97.74
pounds Of butterfat, or an average for
each COW Of 1901 pounds Of milk and
4.65 pounds Of butterfat. The total
number of monthA compared under
each system was 81, and the average
time was about eighty days. Calcula-
lions from these figures indicate that
there was an average monthly In
crease Of As pounds OF milk and IL
pounds of butterfat for each COW
