Feed efficient pigs deal better with stress

At Iowa State University, ongoing research has focused on selective breeding pigs with low residual feed intake. After 10 generations, it has become clear that the benefits extend those of feed efficiency – these pigs also deal better with stress. Feed is the largest cost in pork production; therefore, improving feed efficiency can increase producer profitability. Furthermore, improved feed efficiency can support industry competitiveness, decrease the demand on global feed resources, and comp
