Because of the continuing out
breaks of Salmonella enteritidis
(SE) in die Northeast that have
been traced to this area, SE Pilot
Project representatives indicated a
need for a flock certification prog
ram to help control die problem.
About SO layer industry rep
resentative! met at die Farm and
Home Center Thursday afternoon
to discuss the formation of a prog
ram that will aid in testing flocks
on a regular basis to control SE.
At the meeting, a motion was
unanimously passed to allow the
Pennsylvania Poultry Federation
to petition the USDA Animal and
Plant Health Inspection Service
(APHIS) to provide funds from the
SE Pilot Project to initiate the SE
Project “Second Tier” proposal.
The Second Tier project will
help producers mote effectively
control SE in their flocks and to
deal in a mote direct way with the
increasing concern over food safe
ty, according to Dr. David Kradel,
director of the USDA SE Pilot Pro
ject Also, if the Second Tier prog
ram is carried out successfully, it

may be effective in stemming pos

Hie proposal would involve
input in terms of funding initially
from APHIS. Later, the program
would more actively engage indus
try in funding and other meant,
although details are still being
worked out
According to the Second Tier
proposal, producers would have
the option of having the flock envi
ronment tested at peak production
(or as spent fowl) or Mood egg
monitoring (five samples/week).
Also, cleaning and disinfection
stages would be monitored regu
larly, as woidd chick/pullet testing.
Producers, in effect woiild have
the option of either the egg or the
environment test to help certify
them as under the SE control
program.
The Pilot Project began in April
1992 to help monitor the incidence
and conirol of SE in producer
flocks in the region. The objec
tives, according to Dr. John
Mason, director of the SE Conirol
Program in APHIS, were to iden
tify the number of outbreaks and
provide ways in order to control
and prevent the disease.

But the number of outbreaks of
SE in the put year have continued
to rise at a high level, according to
Mason, and “a lot are coming
from this area," he said. The out
breaks in die Northern are origi
nating here, be said. “It’s obvious
to everyone we have to do more
than what we’ve been doing."
According to Mason, so far
there has been no traceback to any
of the flocks in die SE Pilot Pro
ject, which he said may be an inci
dence of either good luck or better
management u a result of testing.
Data accumulated on 67 flocks
under the program have been accu
mulated and results from that data
have been incorporated in monthly
newsletters, fact sheets, and vari
ous organizational meetings,
according to Kradel.
Regardless, according to
Muon, the SE problem continues
to be tremendous and the issue
now is food safety.
The Pennsylvania Poultry Fed
eration has agreed to gather infor
mation from producers to deter
mine which ways the industry can
help in implementing the Second
Tier program. For more informa

Thoac attending the meeting
agreed with Mason when he said
that the program must remain flex
ible to the industry. Mason said the
main thrust should come from
industry. Kradel said the industry
must sell the program to die public
health agencies, insurance compa
nies, egg buyers, and regulatory
agencies such as the FDA.
Mason indicated the money
from the SE Pilot Project is better
spent with the SE prevention prog
ram than the traceback program.

ment against one feeder space per
ten hogs. In the study, 10 pigs
were housed in each pen by sex
(barrows or gilts). Pigs were given
access to either a one- or two
space feeder from approximately
93-220 pounds. ,
Barrows and gilts responded
equally to the feeder space restric
tion. Overall, daily feed disap
pearance was slightly less for the
10-pig/feeder space group. Other
growth performance indicators
were similar, as shown in the
table.
Under the conditions of this
study, growth rate and feed effi
ciency remain normal when feeder
space is restricted to one space per
10 hogs. It should be noted that
the width of each feeding space
was about 11.5 inches in this
study.
According to lan Taylor and
Stan Curtis, who have conducted
extensive studies on feeder
design, a finishing hog requires
about 14 inches for each feeding
space. This means that, with the
feeder design used in this study,
two hogs would not have had
enough room to comfortably eat,
even though two feeder spaces
may have been available.
