Determining the appropriate soybean meal inclusion level in lactation diets for sows endemically infected with porcine reproductive and respiratory syndrome virus (PRRSv).

ABSTRACT: Soybean meal (SBM) contains many bioactive compounds, such as isoflavones, which possess anti-inflammatory and anti-oxidative properties that may provide nutritional intervention to pigs infected with porcine reproductive and respiratory syndrome virus (PRRSv). The disease results in abortions, stillborn piglets, and overall impairs reproductive success in sows. Today, there are no data available on feeding SBM to sows infected with PRRSv to mitigate the negative impacts of PRRSv on sow and litter performance. A total of 960 sows were used for this study at an endemically PRRSv-infected farm. There were 4 dietary treatments with 20%, 25%, 30%, or 35% SBM inclusion in the lactation diet. All dietary treatments were formulated to target 65 g of standardized ileal digestibility (SID) Lys and
