Abstract

This study was conducted to evaluate the effects of phytase and cholecalciferol supplementation in Cottonseed Meal (CM) and Rice Husk (RH)-based diets on the digestibility of phosphorus by broiler chickens (BC). In study 1 (n= 125) BC was divided into five treatments comprising a Positive Control (PC, D1) without CM and four CM-based diets: Negative Control (NC, D2), NC+vitaminD3 (D3), NC+phytase (D4) and NC+phytase+vitaminD3 (T5) replicated five times. In Study 2, (n=125) BC was also allotted to five treatments comprising a PC (D1) without RH and four RH-based diets: NC (D2), NC+vitaminD3 (D3), NC+phytase (D4) and NC+phytase+vitaminD3 (D5). In the CM-based diet, ileal phosphorus significantly (P<0.05) and reduced with a corresponding increase in the apparent phosphorus digestibility (APD) in D3. In the RH-based diets, APD was significantly (P<0.05) improved in D3. Phytase and vitamin D3 supplementation of CM and RH-based diets increased phosphorus digestibility in broiler chickens.
