It is well worth while periodically reviewing vaccination procedures with the pig farm staff actually giving the injections, including their technique, accurate dosage — ensuring automatic syringes are set correctly — and route of administration (site of injection), advises ACMC veterinary consultant, Paul Thompson.
On larger units, in particular, it is surprising how bad habits can form, especially if there have been changes in staff, he points out.
Reconciling doses and quantity of vaccine ordered against the number of pigs weaned can give a good measure of compliance with vaccination regimes.
