摘 要:采用研制的樱桃谷鸭专用复合添加剂(DSM)分别对700羽樱桃谷鸭父母代种鸭和500羽商品代肉鸭进行饲喂试验,结果表明:试验组种鸭40周龄平均产蛋率比对照组提高9.65%(P<0.01),受精率提高8.76(P<0.01),饲料报酬提高12.5(P<0.01);在对商品代肉鸭的饲喂试验中,试验组肉鸭7周龄平均体重比对照组多增9.82%(P<0.01),饲料报酬提高9.1%,差异极显著(P<0.01).The compound additives studied and produced especially to Cherry Valley Duck are fed to 700 parents and 500 meat duck repectively. As a result,the average laying and fertilized rate of parents(40weekold) in test group is raised by 9.65%(P<0.01) and 8.76%(P<0.01) respectively than the control group,the feed conversion rate is raised by 12.5%(P<0.05).The average body weight of meat duck (7weekold) in test group is increased by 9.82%(P<0.01) compared to the control group.And the feed reward is raised by 9.1%(P<0.01).
