[目的]观察虫草饲料添加剂"虫草欣康"对蛋鸭的生长性能、产蛋率及鸭蛋品质的影响.[方法]选择270只处于产蛋期的蛋鸭,随机分为3组.对照组饲喂基础日粮.试验Ⅰ组饲喂含0.1%虫草添加剂的基础日粮,试验Ⅱ组饲喂含0.4%虫草添加剂的基础日粮.试验期28 d.试验期间,定期观察记录蛋鸭的体重和生长状况,检测鸭蛋外部品质和营养指标.[结果]与对照组相比,试验Ⅰ和Ⅱ组蛋鸭体重略有增加,产蛋率分别提高1.07%和2.15%,蛋重分别提高3.95%和4.16%,料蛋比分别降低了2.54%和4.23%;鸭蛋蛋形、蛋壳厚度稳定;在试验Ⅰ和Ⅱ组,鸭蛋蛋白质含量分别提高了5.55%和17.15%,胆固醇含量分别下降了11.79%和42.14%,卵黄中1gY含量分别提高了13.20%和27.97%,卵磷脂含量分别提高了5.13%和11.69%.[结论]虫草饲料添加剂能够增加蛋鸭的体重,提高蛋鸭产蛋率以及鸭蛋品质.%[ Objective ] To investigate effects of Cordyceps feed additive on growth performance,laying rate and egg quality of laying ducks.[ Method ] A total of 270 healthy ducks in laying period were randomly divided into three groups,90 ducks in each group. The ducks in the control group,group Ⅰ and group Ⅱ were fed common basal diet,basal diet containing 0. 1％ Cordyceps feed additive and basal diet containing 0.4％ Cordyceps feed additive,respectively. The trial lasted for 28 d. During the whole trial, the ducks were weighed and the growth of ducks was observed at an interval of 7 d. The exterior quality and the nutritive indexes of duck eggs were determined. [ Result ] After experiment, the body weights of ducks in the group Ⅰ and group Ⅱ were increased and higher than that in the control group. In the group Ⅰ and group Ⅱ, the laying rate was increased by 1.07％ and 2.15％ ,respectively; the egg weight was increased by 3.95％ and 4. 16％ ,respectively; and the feed to egg ratio was decreased by 2.54％ and 4.23％ ,respectively. The egg shape and egg shell thickness were stable and consistent between control group and experimental group. The protein content of the duck eggs in the group Ⅰ and group Ⅱ was increased by 5.55％ and 17. 15％ ,respectively; the cholesterol content was decreased by 11.79％ and 42. 14％ ,respectively; the IgY level was increased by 13.20％ and 27.97％ ,respectively; and the lecithin content was increased by 5.13％ and 11.69％ ,respectively. [Conclusion] The Cordyceps feed additive can increase the body weight and laying rate of laying ducks and improve the quality of duck eggs.
