“…The results obtained in table 3 indicated that, the final body weight and weight gain of ducks fed diets with 5 and 10% dried poultry waste were significantly (P < 0.05) higher than those fed diets with 15 and 20% dried poultry waste. The results are in agreement with that reported by Hady (1989); Momtaz and Abidur (1990); Nambi et al (1992); Attia et al (1993 ) and Olorede et al (1995) who recorded that, the level of DPW between 10 and 20% could be included in broiler diets with no adverse effect on performance.
