tensive farming, in which animals
are kept solely indoors, has
become so prevalent.
Changes in the way animals are
raised are creating health and
behavioral problems that Dr.
Fraser is working to solve.
"We are trying to design en-
vironments that will accommodate
the natural behavior of the
animals," he says. "This should
help prevent unnecessary stress
and the spinoff will be higher
returns for the producer."
Work on the two-level pen is
continuing. When an easily adap-
table prototype has been
developed, the scientists will test it
under commercial conditions.
They hope producers will soon be
able to pick up the idea for
themselves. O
SWINE RESEARCH
REVIEW 1985
The University of Guelph has
again this year put together a
booklet describing current swine
research. Research conducted at
Agriculture Canada, Ottawa and
Ridgetown College of Agricultural
Technology is also included. The
publication costs were financed by
the OPPMB. The reports in this
year's publication cover a wide
range of topics. Reports on feeding
and nutrition of growing pigs in-
clude: triticale, water quality,
wormseed mustard, vomitoxin,
roasted soybeans, kelp meal,
naked oats, and requirements for
tryptophan and proline. Papers on
reproduction include: energy levels
in sow diets, chelated minerals for
nursing sows, the influence of
boars on estrus in sows and gilts,
effects of boar management on
breeding ability, effects of lighting
on hormones of the estrus cycle,
interesexing, and the effects of
stress on ovary development.
There are several articles reporting
studies of animal behaviour.
Copies of the booklet are available
from the OPPMB or from the Co-
ordinator of Agricultural Exten-
sion, Ontario Agricultural College,
University of Guelph, N 1 G 2W1,
or phone 519-824-4120, extension
3934.

We are serious about herd health. It is the single most important
factor in swine production today. Herd health is #1!
