If it is desired to keep cows in stalls in a round barn of this size,
the circular manger can be enlarged to 38 feet in diameter, which gives
room for forty cows, as shown in Fig. 25, and the silo, to hold
sufficient silage to feed the year round, enlarged to 18 feet in
diameter. The present mow room is sufficient to store enough hay and
bedding for this number of cows.
The barn on the Twenty-acre Demonstration Dairy Farm was built this
large, as it was thought it might be desired at some future time to
increase the size of the farm and herd, and the barn could easily be
changed to accommodate a larger herd by simply enlarging the silo,
without rebuilding the barn.
[Illustration: FIG. 25. SHOWING HOW THIS 60-FOOT BARN MAY BE ARRANGED TO
ACCOMMODATE 40 COWS IN STALLS. TO SUPPLY THIS SIZED HERD AND THE
NECESSARY YOUNG STOCK WITH SILAGE FOR EIGHT MONTHS WOULD REQUIRE A
370-TON SILO, OR ONE 18 FEET IN DIAMETER AND 56 FEET DEEP; WITH A
SEVEN-FOOT FEED ALLEY AND A 2-1/2-FOOT MANGER, THE CIRCLE AT THE
STANCHIONS WOULD BE 38 FEET IN DIAMETER, OR 119-1/3 FEET IN
CIRCUMFERENCE; ALLOWING 4-1/4 FEET FOR TWO PASSAGE WAYS, THE STALLS
WOULD BE 2 FEET 10-1/2 INCHES WIDE AT THE STANCHION, AND 3 FEET 6 INCHES
AT THE DROP.]
