【Abstract】 This experiment preliminarily studied the feeding methods for commercial ducks crossed with Tianfu tabie drakes and Sichuan Ma ducks. It included an experimental group and an control group. The experimental group adopted dry -lot feeding method. The control group adopted the mothed of feeding ducks on groud and supplying ducks with water at fixed time. The results showed that the average daily gain, feed conversion rate and average economic benefit per duck of the experimental group were 14. 3%, 11.0%, 27. 1 % higher than those of the control group, respectively. According to Chi -square test, morbidity of the ducks had slight difference between the above groups (P>0. 05).更多还原
