If the abortion rate is higher than 2% and abortions are not concentrated around any particular group of sows, we should ask ourselves a few questions.
Exploring the benefits of PCV-2 blanket vaccination in sows
The average piglet birth weight from the 3 groups of vaccinated sows was statistically higher than that from the unvaccinated sows.
Clinical case: Increase of returns in summer and low annual prolificacy
The farm reports a problem of low prolificacy (mean annual live births of 11.91) and low fertility in summer, with a marked increase in acyclic returns.
Infectious agents identified in aborted porcine foetuses
PCV-2 and PRRS are the most common infectious causes of abortions. Most abortions are also found to occur during the colder months, regardless of their cause.
Clinical case: Effects of the adaptation to the welfare law in a PRRS outbreak
This farm produces its own gilts from grandmother sows, but taking advantage of the adaptation to meet the needs of the welfare law it was decided to increase its capacity from 600 sows to 1,200.
Reproductive failure by PCV2 infections
PCV2 may reach embryos/foetuses upon transplacental spread during viremia or upon insemination with contaminated semen.
Clinical case: PRRSV and PCV2 interaction in a farm
One month after the beginning of the outbreak of reproductive failure in sows, acute respiratory disorder and diarrhoea that was non-responsive to antibiotics started in weaned pigs aged 6-8 weeks...
Clinical case: Sudden increase in stillborn piglets and suckling pigs mortality
The litter size of the recent and the last farrowing batches was significantly reduced, and the suckling pigs showed an obvious varying weight, condition and viability.
