The Protein Challenge Area aims to sustainably increase the production of high quality protein to meet current and future demands. This Challenge Area will target research that includes, but is not limited to, improving the efficiency of protein production for human or animal consumption, developing alternative protein sources that can create new economic opportunities for producers, enhancing the production of protein-rich plants, reducing the environmental impact of food animal production, and innovative biological and management approaches to preventing and controlling infectious diseases and reducing reliance on medically-important antibiotics.
