Performance and nutrient digestibility in growing pigs fed wheat dried distillers' grain with solubles-containing diets supplemented with phytase and multi-carbohydrase.

Effect of supplementing wheat dried distillers' grain with solubles (DDGS)-containing diet with enzymes on nutrient utilization by growing pigs was evaluated in two experiments. In Experiment 1, 60 pigs weighing ~30 kg were fed five diets that included a corn-based diet (Control), Control with 10% wheat DDGS (DDGS-PC), DDGS-PC without inorganic P source (DDGS-NC), and DDGS-NC plus phytase alone or with multi-carbohydrase for 4 weeks to determine average daily gain (ADG), average daily feed intake (ADFI) and gain-to-feed ratio (G:F). In Experiment 2, 30 barrows weighing 22 kg were fed five diets fed in Experiment 1 to determine nutrient digestibility and retention.
