摘      要：Three experiments(Exp.1,n=144 broilers[Ross×Ross];Exp.2,n=118 mallard ducklings[Anas platyrhynchos];and Exp.3,n=75 mature mallard ducks)were conducted to determine the effects of 3 levels of unmilled hybrid rice on growth performance and organ and gastrointestinal tract develop-ment.The dietary treatments were 1)corn-soybean meal(basal),2)basal+5%hybrid rice,and 3)basal+10%hybrid rice for Exp.1 to 3,respectively.One bird from each pen in Exp.1(n=24)and all the birds in Exp.2(n=118)and Exp.3(n=75)were randomly selected and euthanized to determine linear measurements and organ and gastrointestinal tract weight.In Exp.1 and 2,birds fed 10%rice experi-enced slower growth(P0.05)in Exp.1.However,birds fed 5%rice had significantly increased(P0.05)pancreas,ileum,and jejunum weights in Exp.2,and 10%rice significantly increased(P0.05)liver weight in Exp.3.The addition of 10%unmilled rice to broiler and duck diets may reduce growth performance.
