Ergotism in an organic sow herd and the impact on lactation performance and subsequent reproductive performance

This case reports the level of ergot alkaloids and duration of exposure found under field conditions in a herd that experienced a high neonatal mortality event consequent to agalactia in the sows.

Explaining the persistence of PRRSV in vaccinated breeding herds

Selection of viral variants with enhanced transmission and reduced neutralization susceptibility alongside lateral introductions may explain the persistence of PRRSV in vaccinated breeding herds.

Assessment of hemoglobin concentration in sows and their offspring over consecutive reproductive cycles

Decreasing sow hemoglobin concentration over the reproductive cycle and lack of post-weaning recovery in parity 3 indicates iron declines with advancing parity and may impact long-term health.

Environmental enrichment affects immunity and reduces disease severity in pigs after co-infection, with stronger effects when applied from birth than from weaning

Enriched housing from birth reduced disease severity to co-infection with PRRSV and A. pleuropneumoniae.

African swine fever virus vaccine strain Asfv-G-∆I177l reverts to virulence and negatively affects reproductive performance

ASFV-G-ΔI177L is not genetically stable and, therefore not safe for use in ASF vaccines. ASF vaccine candidates should be tested for safety in pregnant animals.

The genetic basis of swine inflammation and necrosis syndrome and its genetic association with post-weaning skin damage and production traits

Piglets genetically less likely to present swine inflammation and necrosis syndrome signs are also more unlikely to suffer combined skin damage after weaning.

Quantitative risk assessment model of the presence of PED and ASF viruses in spray-dried porcine plasma

Under the current conditions, the model estimated that an inactivation level (log-kill) of 7.0, 7.2, and 7.3 log must be achieved to manufacture a 10-, 15-, and 20-tons batch size, respectively.

Comparison of a novel rapid sampling method to serum and tonsil scraping to detect PRRSV in acutely infected sows

Results suggest great potential of tonsil-oral scraping as a novel, practical, and rapid tool for PRRSV RNA detection in sows to assess sow herd status.
