least 30 days after calving."
When possible. farmers should prevent
the entry to the barns of people who
f equent other farms. Also, when a cow
aborts her calf a veterinarian should be
notified immediately.
Dr. McGowan notes that 940 Ontario
farmers have had their herds tested and
have received brucellosis -free listed herd
status. which allows a farmer to ship cattle
without a brucellosis test anywhere in
Canada. and allows exports to the United
States on the basis on one 30 -day test.
Another 3,314 herds in Ontario have had
the first test towards this status.
"Above all. farmers should not become
complacent about brucellosis. The effort to
detect and eradicate the disease must be
maintained."
Hip roof plans available
Braced rafter (hip roof) plans arc now
available from the Canada Plan Service
(CPS). according to Jim Arnold. Ontario
Ministry of Agriculture and Food agri-
cultural engineer.
This new series of plans was developed
tomeet the increasing demand for this type
d roof. he says.
The braced rafter roof. which resembles
the traditional two-story barn roof. can be
used for a variety of farm buildings. It
allows for more vertical storage space than
conventional trussed roofs.
The extra space makes it ideal for fruit
and vegetable storages, or for two-story
dairy barns where farmers want to store
hay or straw above the stall area.
Its esthetic appearance and storage
capability also make it a popular choice for
horse barns.
The CPS plans for braced rafter roofs are
designed for either No. 2 grade spruce or
No. 2 grade Douglas fir lumber. Metric
and imperial unit plans are available for
spans from 6000 mm (20 ft.; to 21 600 mm
(72 ft.). in increments of 600 mm (2 ft).
"These plans are designed to withstand
local snow and wind loads. and the dead
load of the roof itself." says Mr. Arnold.
"Thcyaredesigned for ease of construction,
using the smallest amount of construction
materials."
Plans must be strictly followed, part-
icularly in anchoring the roof to the
sidewall or niow floor. advises Mr. Arnold.
Improper use and contruction of hip roofs
will result in substandard buildings.
' CPS plans are designed by experts from
provincial ministries of agriculture. in
cooperation with the Canada Plan Service
Design Center. Agriculture Canada,
Ottawa. In Ontario. plans are available
from agricultural engineers at local offices
d the Ministry of Agriculture and Food.
Your area agricultural engineer will be
able to help you adapt plans to your
particular needs and local conditions.
