07-Mar-2018Marius Opreain my opinion, sow blanket vaccination against PCV2 will have a big impact in pigs vaccination against PCV2. Some farmers are happy that are vaccinating all the sows at once, but they forget about piglets that are born from those sows. Depending on status of sows at vaccination time (lactation or various age of gestation) piglets will have different levels of MDA and it is mandatory to make ELISA checking before vaccination
Which is the best age for piglet PCV2 vaccination?
This article deals with the factors to be considered for deciding the optimal time of vaccination against PCV2 and shows the results of a study that evaluates the efficacy of different vaccination programs in PCV2 subclinically infected piglets.

PCV2 viraemia, a load-dependent effect on average daily weight gain during the postweaning period
The loss associated with decreased ADWG was of 13.1 € and 7.5 €/pig at 21 weeks of age for pigs with high and medium serum PCV2 load under the scenario studied.

05-Jan-2015Alex EggenThank you for this interesting paper. It is important to continue to stress that PCV2 related economic damage is a gradual scale. Pork producers often do not realise that by optimising their PCV2 protection protocol that they can have an even higher return on their investment. Secondly the CoV that you point out is equally important. Uniformity is a key element in our industry nowadays. The postive effect that PCV2 vaccination has on the level of uniformity and therewith the reduction in time needed to empty a barn, makes PCV2 vaccines a management tool!

Update on the diseases associated with the PCV2: clinic, diagnosis and control
The PCV2 has been associated, in an ongoing way and throughout time, with more pathologies called, collectively, diseases associated with the PCV2 (PCVDs): PCV2 systemic disease, PCV2 lung disease, PCV2 enteric disease, PCV2 reproductive disease,PCV2 subclinical infection and porcine dermatitis and nephropaty syndrome.

Effect of the viraemia due to the porcine circovirus type 2 (PCV2) on production parameters
The most effective way of avoiding the production losses associated with the PCV2 consists in avoiding the appearance of the viraemia by inducing a passive or an active immunity that minimizes the circulation of the virus in the farm.
