Induced molting is a common
management practice in the egg
industry.
There are different reasons
behind making the decision to
induce molting, one of which is to
improve egg quality. Economic
considerations such as the antici

nitely another important reason to
induce molting.
There are different methods that
are used to artificially induce molt
ing; however, all are aimed at giv
ing the flock a rest at the end of a
period of egg production so that it
may perform more efficiently dur
ing a second cycle.
The most common procedure,
which is called “conventional,”
provides no food or water for two
days and is followed by providing
water and 45 grams of feed/hen
every other day for a period of one
week.
Oyster shell is provided on a
continuous basis throughout the
nine days. From days 10-60, water
is provided continuously and each
hen receives 90 grams of feed.
During the 60-day period, the light
received is reduced from 16 to 8
hours/day. Following the 60 days,
the hens are put back on full-feed
layer ration and light received is

back to 16 hours/day.
Another method used to induce
molting is called “California” and
incorporates a longer period of
complete feed, withdrawal (10
days) followed by nothing but
cracked com for 18 days. Water
and oyster shell are provided for
the total 28 days. As in the conven
tional method, in the California
program, light is reduced from 16
to 8 hours/day throughout the
28-day period. Following the
28-day period, the hens receive 16
hours of light and are put back on
full-feed layer ration.
The third method to induce
molting is to use zinc at 20,000
ppm for S days and then back on
full-feed layer ration.
In our laboratory, we conducted
an experiment to study the differ
ence in the effects of the above
mentioned methods of induced
molting on subsequent perfor
mance and on the immune
response. White Leghorn hens
were used following 12 months of
production. Hens were divided
randomly into four groups and the
three methods of induced molting
were applied to the first three
groups. The fourth group was not
treated and served as control. Body
weights, egg production, egg qual
ity, and immune responses were
measured at different time periods.
We found that relative to control
hens, body weights of hens in the
California program woe reduced
the most and hens in the conven
tional group were reduced the least
during the treatment periods. At
peak egg production, body weight
of hens in all groups were similar.
Egg production and interior egg
quality were better in the conven-

However, eggshell weight was
higher in the California group than
in the other three groups. In con
