Health Effects of Soybean Meal-Fed Pigs with Special Emphasis on Isoflavones

Ryan Dilger
October 2015

Building upon recent findings that feeding increased concentrations of dietary soybean meal confers benefits to young pigs infected with porcine respiratory and reproductive syndrome (PRRS) virus, this proposed project sought to:

  1. Quantify variability in soy isoflavone content within value-added soy products
  2. Develop an isoflavone-free soy product for testing our hypothesis that these bioactives are responsible for immunomodulatory effects in PRRS virus-infected pigs
  3. Provide direct evidence of whether soy-derived isoflavones are responsible for the observed growth performance benefits in young pigs infected with PRRS virus
