Use of Specialty Soy Products to Replace Poultry Meal and Spray-Dried Blood Plasma in Diets Provided to Nursery Pigs Housed in Commercial Conditions

A total of 2,260 pigs (PIC TR4 × [Fast LW PIC L02]; initially 14.8 lb) were used to evaluate a specialty soy protein source as an alternative poultry meal and spray-dried blood plasma on nursery pig performance in commercial environment.
