title: Performance and nutrient digestibility in growing pigs fed wheat dried distillers' grain with solubles-containing diets supplemented with phytase and multi-carbohydrase.
abstract: 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. Pigs fed DDGS-PC and Control diets had similar ADG and G:F. The ADG and G:F for DDGS-PC diet were higher (P < 0.05) than those for DDGS-NC diet. Phytase improved (P < 0.05) ADG, G:F, total tract P digestibility and P retention by 6.6, 8.7, 86.0 and 85.5%, respectively. Addition of multi-carbohydrase to phytase-supplemented diet did not affected growth performance, but reduced (P < 0.05) P retention. In conclusion, inclusion of 10% wheat DDGS in growing pig diet may not affect growth performance of growing pigs. Phytase supplementation to wheat DDGS-containing diet can eliminate the need for inorganic P supplement in pig diets.
