Section 105.130 Requirements
for Establishing and Maintaining a Herd Under the Voluntary Porcine
Reproductive and Respiratory Disease (PRRS) Monitored Herd Program
a) The
following definitions shall be applicable to this Section:
"Accredited
laboratory" means a laboratory operated by the Illinois Department of
Agriculture or the University of Illinois College of Veterinary Medicine, or a
laboratory approved by the Director (on the basis that it is using USDA
approved methods).
"Herd"
or "premises" means all animals under common ownership or supervision
on a specific geographic area. The herd or premises is defined by the owner and
veterinarian, and may include all or a portion of pork production under their
control. A premises describes a physical space that is dedicated for use by
the producer when entering the PRRS monitored herd program. For an entire
production system to be monitored, all phases of production must be sampled and
participate in the program. Producers can select the production group they wish
to monitor. All phases of production up to and including the
"selected" group must participate in the program. If multiple
locations input swine into the proposed PRRS monitored production herd or
premises, all sites must be sampled separately to validate the final PRRS
monitoring herd defined premises.
"PRRS"
means porcine reproductive and respiratory syndrome.
b) Criteria for herd to enter into or to remain in the voluntary
monitoring herd program:
1) Participation in this program is voluntary and the
producer/owner is responsible for the cost of testing.
2) All breeding swine that have been tested must have permanent
identification such as registry association approved individual tattoo, ear
notch, registration number or approved ear tags. "Approved ear tags"
means any ear tag that is tamper resistant and has been approved for use by the
USDA. Information concerning manufacturers of approved ear tags may be
obtained from the Department.
3) The owner annually signs a producer agreement form verifying
that the producer or manager:
A) understands the clinical signs of PRRS;
B) identifies a herd veterinarian;
C) agrees to work with that veterinarian in the event clinical
signs of PRRS develop;
D) identifies the premises and animal production groups that will
be monitored and the average number of animals per premises or production
group; and
E) outlines the testing procedure employed to verify PRRS testing
qualifications.
4) Quarter sample size for initial monitoring for all production
systems and for monitoring phase for farrow-weaning sites (Table A):

6) Upon completion of the four qualifying tests, the Director
shall issue a certificate of PRRS monitoring for the herd. A new certificate
will be issued annually upon completion of the required monitoring test and the
receipt of the annual producer agreement form.
c) Procedure
for monitoring farrow-finish and seedstock producer herds:
1) Initial herd monitoring:
A) Test the required number of swine (Table A) in the
grow-finisher herd at 90-day intervals (+ or - 15 days) for a period of 12
months (4 tests total).
B) Blood test the required number of breeding stock (Table A) at
90-day intervals (+ or - 15 days) for a period of 12 months (4 tests total).
No sow shall be sampled twice with 101 sows or more in the breeding herd.
Individual identification is required.
C) External additions must be held in isolation and either tested
prior to or within 10 days after arrival and identified and tested 40-60 days
after arrival. Only after the retest can the animal be released from
isolation. If a positive animal is detected, all co-mingled animals must be
retested 30-40 days after the positive is disclosed. Any PRRS positive animal
must be promptly removed from the monitored premises.
D) All internal replacements (gilts, boars, teaser boars) must be
PRRS test negative prior to entry into the breeding herd.
2) Maintenance of monitored herd status:
A) Test animals in the grow-finisher according to Table B on
90-day intervals (+ or - 15 days). Pigs must weigh at least 90 pounds.
B) Test breeding herd according to Table B on 90-day intervals (+
or - 15 days). Sows must be of all parities and from each production phase
(gestation, post-weaning, lactation, and off-premises gestation). Individual
identification is required.
C) Additions to the herd shall be as prescribed in subsection
(c)(1)(C).
d) Procedure
for monitoring farrow-feeder pig premises:
1) Initial herd monitoring:
A) Test the required number of feeder pigs (Table A) at 90-day
intervals (+ or - 15 days) for a period of 12 months (4 tests). The sample
should represent the oldest pigs in the nursery. Pigs must be present in the
nursery at least two weeks prior to the sampling to be eligible for testing.
No identification is required. Multiple pens and litters must be sampled.
B) Test the required number of breeding swine (Table A) at 90-day
intervals (+ or - 15 days) for a period of 12 months (4 tests). No sow will be
sampled twice in herds of 101 or more sows during the year. Individual
identification is required.
C) External additions must be held in isolation and either tested
prior to or within 10 days after arrival and identified and tested 40-60 days
after arrival. Only after the test can the animal be released from isolation.
If a positive animal is detected, all in-contact animals must be retested 30-40
days after the positive is disclosed. Any PRRS positive animal must be
promptly removed from the monitored premises.
D) All internal replacements (gilts, boars, teaser boars) must be
PRRS test negative prior to entry into the breeding herd.
2) Maintenance of monitored herd status:
A) Test the feeder pigs according to Table B on 90-day intervals
(+ or - 15 days). The sample should represent the oldest pigs in the nursery.
Pigs must be present in the nursery at least two weeks prior to the sampling to
be eligible for testing. No identification is required. Multiple pens and
litters must be sampled.

intervals (+ or - 15 days) for a period of 12 months (4 tests). No sow will be
sampled twice in herds of 101 or more sows during the year. Individual
identification is required.
C) External additions must be held in isolation and either tested
prior to or within 10 days after arrival and identified and tested 40-60 days
after arrival. Only after the retest can the animal be released from
isolation. If a positive animal is detected, all in-contact animals must be
retested 30-40 days after the positive is disclosed. Any PRRS positive animal
must be promptly removed from the monitored premises.
D) All internal replacements (gilts, boars, teaser boars) must be
PRRS test negative prior to entry into the breeding herd.
2) Maintenance of monitored herd status:
A) No piglet sampling is required.
B) Test breeding herd according to Table B on 90-day intervals (+
or - 15 days). Sows must be of all parities and from each production phase
(gestation, post-weaning, lactation and off-premises gestation). Individual
identification is required.
C) Additions to the herd shall be as prescribed in subsection
(e)(1)(C).
f) Procedure for monitoring boar stud premises where only
seronegative boars can reside:
1) Initial herd monitoring:
A) All boars must be tested every six months (+ or - 15 days) for
a period of 12 months (two tests).
B) All incoming boars must be tested prior to arrival or within 10
days after arrival and again 40-60 days after arrival. Boars must originate
from a farm where there has been no evidence of PRRS for at least one year.
The herd of origin must not be using PRRS vaccine.
2) Maintenance of monitored herd status:
A) Test the required number of boars (Table B) every 90 days (+ or
- 15 days).
B) All incoming boars must be tested prior to arrival or within 10
days after arrival and again 40-60 days after arrival. Boars must originate
from a farm where there has been no evidence of PRRS for at least one year.
The herd of origin must not be using PRRS vaccine.
g) Suspension
or revocation of monitored herd status:
1) If a positive animal is detected during a monitoring test, the
monitored herd status shall be suspended until all in-contact animals have been
retested 30-40 days after the positive is disclosed. Any PRRS positive animals
must be promptly removed from the monitored premises. If subsequent positives
are revealed, the monitored herd status shall be revoked.
2) Failure to conduct the required testing shall result in the
revocation of the monitored herd status.
