Does genetics or litter effects influence mortality in PMWS?
Proceedings of the 18th IPVS Congress, Hamburg, Germany, 2004 - Volume 2:809
This study was based on the data collected in a sow commercial farrow-to-finish farm experiencing a PMWS outbreak. The data regarded 16278 piglets weaned piglets in 1637 litters over an almost 3-year period. Piglet mortality due to PMWS was found significantly lower in sows with parity 1 and 2 than in sows with later parities suggesting that piglets born of older sows receive less colostral protection. No genetic effect was demonstrated on this farm.
