Soybean meal positively affects pigs with PRRSV.

Soybean meal positively affects pigs with PRRSV. Porcine reproductive and respiratory syndrome virus (PRRSV) is the most widespread disease in the swine industry. In sows, PRRSV causes reproductive problems during gestation, including abnormal litters or abortions. Growing pigs with the disease will have respiratory problems and poor growth. Increased soybean meal concentrations in the diet may help alleviate the effects of PRRSV in infected weanling pigs. PRRSV infected pigs fed high soybean meal concentrations had a more efficient virus elimination compared to PRRSV infected pigs fed the low soybean meal diet. Soybean meal is the primary protein source fed to swine. It also contains isoflavones, compounds that have anti-inflammatory and antiviral properties. Soybean meal positively affects pigs with PRRSV.
