Hello all,

I was wondering if the PCV2 vaccine is working. The vaccine will be availible in the USA soon.

    Dear Shaun,
    Definitively, to get a reply many months after the message postage will not be of any help, but... just in case! Maybe you already know it, but some results on PCV2 vaccination were presented by US/Canadian colleagues at the Allen D. Leman Swine Conference (last September), showing a really great performance (although only preliminary results were shown). In fact, all vaccines used (Merial, Fort Dodge, Intervet) seemed to work properly, lowering mortalities from 15 to 2-3% in the most successful cases. Will see if these results are further confirmed in the next few months...
    At this moment maybe yourself have some experience with PCV2 vaccination. Could you share your ideas/results on it if this is the case?
    Very best regards,

    Dear Joaquim,

    Thankyou for the reply. Since that post I have vaccinated my finishing animal with fort dodge and intervet products. I will be selling my first vaccinated animals this wednesday. With 25 days until closeout, I am currently at 4% deathloss from 25 Kg to current weight. This will be my first group deathloss under 10% in over 2 years and first under 20 % in the last 12 months.

    One thing I do see, That there is a lot more slow growing pigs that will barely make market weight. I wonder if the vacccine helps a lot but is just a little short of perfect. Also pigws that show signs of PNDS skin lessions end up living which was not the case before vaccine.

    Are your feed cost soaring as fast as they are here in the USA?

    This article offers an update on the issue. Here's a small excerpt from the article PCV2 Vaccine on Trial Versus PMWS:

    The argument for sow vaccination against PMWS remains that this should supply the earliest possible protection to piglets from an infection of the PCV2 circovirus considered responsible for the syndrome. This view has won most support where troubles with the syndrome have been in the acute phase. Typically, the virus has infected a herd in which the sows carry few protective antibodies and therefore it can cause extreme damage to weaned litters. An initial post-weaning mortality rate as high as 35% has not been unusual, even if this drops back later towards 10% as immunity builds and possibly falls again to 5% when strict hygiene precautions are applied.

    Even if filling sows with vaccine succeeds in reducing acute 30%-plus death losses, however, doubts are expressed over its ability to contend with a situation of chronic infection among weaned pigs. What is more, fingers are pointed to signs that PMWS is changing its face and becoming a killer more in the grow-finish stage of production than in the nursery. Increases in mortality starting at about 12 weeks are being described instead of the original picture of outbreaks around the time of weaning.

    A longer extensive explanation is available if you want to read the rest of the article.

    This is why the PCV2 vaccine is given to piglets at cover them until bacon weight.

    The vaccine has much better results if given at weaning to all piglets...
