24 THE RURAL VOICE
pigs, $18.32 per tonne (55 cents a
bushel). The greatest potential for
savings is for the one -farm feeder,
Yungblut said.
For pigs under 70 kg. there are no
problems with feeding high oil corn
to make up the full corn part of the
ration but with pigs over 70 kg. it
should be diluted by one third with
regular corn because the high oil
content could damage the meat
quality.
High oil corn has the added
value of causing Tess dust
when it is ground into feed
and millers say it takes Tess power to
grind it.
Shorter season varieties are likely
to be available in the next few years,
Yungblut predicted. The corn may
come off the field one per cent wetter
than regular corn but it dries down
well. 1t needs to be stored separately
from regular corn and should be
analysed and a nutritionist should be
consulted for best use.
Batch farrowing allows
smaller operators adopt
large operators'
technology
Dr. Frank Kains spoke on batch
farrowing as a way of letting smaller
operators adopt the technologies of
large operations. By having sows
farrow in groups there can be better
attention to detail and more litters
available for cross -fostering, he said.
It allows all-in/all-out operations
with fewer rooms, allows major tasks
such as washing and processing to be
done less frequently, means that
more weaner pigs can be offered for
sale at one time and there are regular
periods of less work during which
maintenance, holidays and field work
can be scheduled.
Disadvantages include the need to
breed a larger number of sows at one
time, but widespread use of artificial
insemination can reduce this concern.
Some farmers don't like the heavy
burden of work at one time instead of
spreading it out and may need to hire
part-time help during peak times. It
may take six months to get the
system going during which time pigs
are weaned at a wide variety of ages
and cash flow may suffer.
