Effects of various levels of wheat bran in laying duck feed was conducted to determine effects of wheat bran (WB) on production performance and transferred knowledge to laying duck farmers. The study was divided into two experiments (2-8 and 9-21 weeks of age duck) using completely randomized design with 5 levels of wheat bran(0, 5, 10, 15 and 20%) in laying duck diets , two hundred and twenty-five female Khaki Campbell ducks were randomly allotted to treatments of fifteen laying ducks per pen with three pens per treatment. Experiment 1 Laying ducks fed wheat bran were non-significantly in body weight gain, feed intake,feed conversion rate, average daily gain (P>0.05) when compared to control diet. Treatment 5% wheat bran was the least cost diets (48.20 bath) when compared to control diet (P<0.05). Experiment 2 Laying ducks fed 5% wheat bran were significantly higher in body weight gain and average daily gain (P<0.05) than other treatments. Moreover, treatment 5% wheat bran improved feed conversion rate among treatments. This treatment was the least cost diets (86.64 bath) when compared among treatments. There was no mortality. The current study suggests that wheat bran could be used successfully in laying duck diets. Technology and skills had been transferred by workshop training to thirty farms. Demonstration farms were established and recommendation of the researcher was also explored.
