摘　　要：旨在研究日粮中钙粉代替钙粒对鸭产蛋性能、蛋品质和血清生化指标的影响。选用产蛋期健康黑鸭300只,随机分为两组,分别为钙粒组和钙粉组。每组15个重复,每个重复10只鸭。结果表明,钙粉代替钙粒后,蛋鸭的产蛋率显著提升(P<0.05),鸭蛋的蛋壳和蛋壳强度显著提高(P<0.05)。与钙粒组相比,钙粉组的平均蛋重和蛋黄重降低。使用钙粉制粒延长了制粒机各个部件的使用寿命。综上,钙粉代替钙粒可以提高蛋鸭产蛋率,减少鸭蛋破损,延长机器寿命,提高经济效益。The aim of this study was to investigate the effects of calcium powder instead of calcium granules in diet on laying performance,egg quality and serum biochemical indices of ducks.Three hundred healthy black ducks were randomly divided into two groups:calcium granule group and calcium powder group.There were 15 replicates per group and 10 ducks per replicate.The results showed that when calcium powder replaced calcium granules,the egg production rate and eggshell strength of duck eggs were significantly increased.The average egg weight and yolk weight of the calcium powder group were lower than those of the calcium granule group.The use of calcium powder granulation prolongs the service life of each component of the granulation machine.In summary,calcium powder instead of calcium granules can improve the laying rate of laying ducks,reduce the damage of duck eggs,extend the machine life and improve economic benefits.
