TI  - Insight into the Economic Effects of a Severe Korean PRRSV1 Outbreak in a 
      Farrow-to-Nursery Farm.

AB  - Porcine reproductive and respiratory syndrome (PRRS) is a disease that has 
      inflicted economic losses in the swine industry. The causative agent, porcine 
      reproductive and respiratory syndrome virus (PRRSV), is known to have a high 
      genetic diversity which leads to heterogeneous pathogenicity. To date, the impact 
      of PRRS outbreaks on swine production and the economy of the swine industry in 
      South Korea has been rarely reported. In this study, we compare the reproductive 
      performance in the breeding-farrowing phase and growth performance in the nursery 
      phase, in two 27-week periods, one before and one after a PRRSV1 outbreak on a 
      650-sow farrow-to-nursery farm caused by a Korean PRRSV1 isolate which was 
      genetically distinct from vaccine strains or other global strains. The 
      reproductive performance of sows and the growth performance of nursery pigs were 
      compared using row data consisting of 1907 mating records, 1648 farrowing 
      records, and 17,129 weaning records from 32 breeding batches. The following 
      variables were significantly different between the pre-PRRS outbreak period and 
      the post-PRRS outbreak period: the farrowing rate (-7.1%, p < 0.0001), the 
      abortion rate (+3.9%, p < 0.0001), the return rate (+2.9%, p = 0.0250), weaning 
      to estrus interval days (+1.9 days, p < 0.0001), total piglets born (-1.2 
      pigs/litter, p < 0.0001), piglets born alive (-2.2 pigs/litter, p < 0.0001), 
      weaned piglets (-2.7 pigs/litter, p < 0.0001), pre-weaning mortality (+7.4%, p < 
      0.0001), weaning weight (-0.9 kg/pig, p = 0.0015), the mortality rate (+2.8%, p < 
      0.0001), average daily gain (-69.8 g/d, p < 0.0001), and the feed conversion 
      ratio (+0.26, p = 0.0036). Economic losses for a period of 27 weeks after a PRRS 
      outbreak were calculated at KRW 99,378 (USD 82.8) per mated female for the 
      breeding-farrowing phase, KRW 8,968 (USD 7.5) per pig for the nursery growth 
      phase, and KRW 245,174 (USD 204.3) per sow in the post-outbreak period. In 
      conclusion, the farrow-to-nursery farm in our study suffered extensive production 
      and economic losses as a result of a PRRSV1 outbreak.
