Salmonella reduction - for high welfare pig production

Recent studies have demonstrated that providing rye-rich feed promotes animal health. The German Federal Ministry of Food and Agriculture (BMEL) has granted approval for the Rye-SAFE project, together with KWS & industry partners.

  • The Rye-SAFE project aims to investigate if salmonella contamination in sow husbandry and piglet production can be reduced by using rye-rich feed
  • Rye is rich in dietary fibers such as arabinoxylan, digested in the hind gut
  • Hind gut fermentation of (SCFA)s* produce more butyrate, and directly reduce salmonella gut wall attachment
  • Butyrate also acts to positively influence energy supply during farrowing

  • It was possible to reduce salmonella contamination among the animals by two-thirds — entirely without medication and only by changing the feed.

Rye offers distinct benefits for sow feeding which perfectly align to high welfare pig production:

  • Gestation: Rye boosts satiety – reduces stress, fighting over feed & lowers obesity risk
  • Shorter Farrowing Duration: Arabinoxylan in rye is converted to butyrate in the hind gut. Butyrate helps raise energy supply at a time of reduced feed intake
  • Lactation: Butyrate from the hind gut fermentation of rye helps increase colostrum quality & IgG and IgA (maternal antibody) levels

Sow diet (period & lactation)


  • Simplified farrowing conditions
  • Better entry to lactation


  • Ensures high colostrum (IgG & IgA) levels
  • Less MMA (mastitis, metritis, agalactia)
  • Reduced salmonella
  • Reduced stress

Piglet development

Piglet development

  • Better colostrum intake
  • Increased gut health
  • Improvement weaning period
  • Less salmonella
  • Better feces quality
