Objective: The present study is to examine the effect of high inclusion of co-products in pig diets (referred to as an alternative diet) during the finishing stage on pig growth performance, meat quality and boar taint compounds.Methods: Growing pigs were fed an alternative diet made with distillers dried grains with solubles (25%), canola meal (20%), and wheat middling (15%) or a control diet based on barley and soybean meal to investigate the impact of co-products on pig performance and meat quality. Sixteen female and sixteen entire male Duroc×(Large White×Landrace) pigs (22.6±2.07 kg, body weight±standard error) were equally allocated to the diets.Results: Pigs fed the alternative diet had a lower feed intake; however, growth rate and feed conversion efficiency were unaffected by diet. A diet by sex interaction was found for gain:feed whereby males fed the alternative diet had the best feed conversion (p
