试验选取9周龄的白羽半番鸭母本1080只，测定6种不同的限饲方法对白羽半番鸭母本育成期生长性能、产蛋期产蛋性能的影响。结果表明：白羽半番鸭母本21周龄的平均体重以T2组最高，为2．86 kg，T1组为2．80 kg，T1与T2组差异不显著，T1组整个时期的生长曲线与其他组相比增长较均衡；而T6组严重偏离其他各组。 T1组开产最早，300日龄入舍鸭的平均产蛋量最高，为98．78枚／只，T6组最低为79．27枚／只，此两组差异极显著，T1与T3、T5与T6差异显著，其他各组均差异不显著；T1组产蛋高峰期的持续时间也比其他各组长。以T6组饲料成本最低，T1组饲料成本最高；T1组所获得的经济效益最高。%A total of 1080 9-week-old white-plumage mule ducks were randomly divided into six groups ( T1 ~T6 ) , these ducks were restrictedly fed by six different ways till they were 21 weeks old, and the influences of different restricted feeding ways on their growth performance and egg -laying performance were studied .The results indicated that the average body weight of 21-week-old ducks in group T2 was the highest (2.86 kg), followed by that in group T1(2.80 kg), but there was no significant difference in average body weight between group T 2 and group T1.In the whole period, the growth curve of ducks in group T1 was more equilib-rious than that in other groups , while the growth curve of ducks in group T 6 seriously deviated from that in other groups .The ducks in group T1 laid earliest.The 300-day-old ducks in group T1 had the highest average egg production (98.78 egg/duck), while in group T6 had the lowest average egg production (79.27 egg/duck).The duration of egg-laying peak period of ducks in group T 1 was also longer than that in other groups .The feed cost in group T 6 was the lowest , while that in group T 1 was the highest .The eco-nomic benefits of ducks production in group T 1 was the highest .
