INTRODUCTION
The number of cracked eggs re
ceived
by
grading
stations
has
doubled in the past fifteen years. A
current
estimate
of
the
annual
loss
to Canadian egg producers is four
million
dollars
(10). The growing
problem of cracked eggs is aggra
vated by the trend toward higher
egg
production
per
hen
and
more
extensive use of
egg-handling
equip
ment. The successful design of egg-
handling
equipment
requires reliable
data on
physical
and mechanical pro
perties
of eggs.
