In the control group(Ⅰ)they were fed the basal diet. In the test group(Ⅱ, Ⅲ, Ⅳ)they were added 0.03%, 0.05%, 0.1% chitosan on the basis diet, the trial period last seven weeks. The test results showed that: added 0.03% to 0.1% chitosan to duck's diets could effectively improve the growth performance, significantly improve the average of daily gain and feed conversion ratio of ducks, the best dosage is 0.05% chitosan in diet.
