Abstract

Wheat distillers dried grains with solubles (wheat-DDGS) is a viable source of phosphorus(P) for poultry. Two experiments were conducted to determine the true ileal P digestibility (TPD) and true total tract P retention (TPR) of wheat-DDGS without or with phytase supplementation for broilers and turkeys. In experiment 1 (broilers), wheat-DDGS inclusion linearly decreased (P < 0.05) dietary ileal DM digestibility and total tract DM and Pretention. The coefficient of TPD without or with phytase for broilers was 0.94 or 0.96,respectively. The coefficient of TPR was 0.92 and 0.94 without or with phytase, respectively.In experiment 2 (turkeys), wheat-DDGS inclusion linearly decreased (P < 0.05) dietary ileal DM digestibility and total tract DM retention. The coefficient of TPD of wheat-DDGS for turkeys was 0.76 or 0.82 without or with phytase, respectively. The coefficient of TPR ofwheat-DDGS without or with phytase was 0.71 and 0.82, respectively. Phytase had no effect(P > 0.05) on dietary ileal DM digestibility, total tract DM retention, ileal P digestibility and total tract P retention for broilers and turkeys. Phytase had no effect (P > 0.05) on TPD and TPR for broilers and turkeys. It was concluded that wheat-DDGS is a valuable dietary sourceof digestible P for broilers and turkeys.
