Piglet vaccines: most-effective against PCVAD
Piglet vaccines have been the most effective defence
against porcine circovirus associated disease for one Canadian swine
Dr FranÃ§oise Cardinal believes that the introduction of new vaccines
combined with improved management practices has been extremely effective in
controlling the disease.
PCVAD is triggered by porcine circovirus type 2 and can be characterised by a
wide variety of clinical signs from respiratory symptoms to reproductive failure
to reduced productivity and to death.
Dr Cardinal comments that ,in his
experience, the piglet vaccines have been more effective than the sow vaccine.
He emphasises the importance of maintaining good biosecurity measures to keep
PCVAD and other diseases under control.
Currently, there are three
vaccines available in Canada, two which are administered to the piglet and one
which is administered to the sow. An additional piglet vaccine is expected to
become available shortly on the market.
