IBR accreditation programme:
Test all cattle of 12 months old and older plus any bought-in cattle under 12 months old
If clear carry out second qualifying test 4 weeks to 12 months later (same testing as above)
Annual test after gaining accredited status:
Beef herds:
Every 12 months test a statistical proportion of herd (figures from table below) involving cattle 12 months old and older (sample from cow herd and sample from followers required).
All bulls, any non-homebred cattle that have originated from a non-accredited herd plus all IBR marker vaccinated must be tested annually in addition
For group sizes between these figures refer to next highest number e.g. for 80 cows sample 38.
As an example, for a 100 cow herd with 20 followers sample 38 cows and 19 followers.
Dairy herds:
Quarterly bulk milk testing is required.
Every 12 months a statistical proportion of youngstock from each group aged 12 months and older must be sampled according to the number in the table above.
All bulls, any non-homebred cattle that have originated from non-accredited herds plus all IBR marker vaccinated must be tested annually in addition.
Vaccinated Monitored Free programme:
Test all cattle 12 months old and older plus any bought-in cattle under 12 months old
If herd test is clear carry out second qualifying test 4 weeks to 12 months later (same testing as above)
To maintain vaccinated monitored free status:
Beef herds:
All breeding stock plus any animals that are non-homebred and originated from a herd that was not IBR accredited must be tested annually.
Dairy herds:
Quarterly bulk milk testing is required.
All breeding stock plus any animals that are non-homebred and originated from a herd that was not IBR accredited must be tested annually.
Added animal testing
Quarantine testing is optional for animals sourced direct from IBR accredited herds.
If cattle are from a non-IBR accredited herd (or from an accredited herd but purchased through a market) they must be placed in quarantine and tested after a minimum of 28 days (an earlier additional test is advisable either before purchase or early in quarantine period).
Cases where IBR could be involved and testing is required to rule out disease:
Blood sample at time of clinical signs and again after 14-21 days to check for seroconversion to IBR using IBR antibody ELISA. Optional nasal/ocular swabs/BAL at time of clinical signs for IBR PCR.
Any cow/heifer that aborts, has a stillborn calf or has evidence of resorption must be blood tested for antibodies to IBR virus. Advisable to submit abortion material for testing.
