摘要: 选用1600羽出壳1 d的樱桃谷鸭随机分为8组,分别饲喂不同配比和组合的抗生素、沸石、微生态制剂(EM)、中草药和甘氨酸微量元素螯合物等添加剂饲料,探讨了不同饲料添加剂对肉鸭生长性能的影响,并对鸭舍的有害气体含量进行了研究。结果表明:饲料中添加沸石、EM、中草药对提高肉鸭的日增重和降低料肉比有显著效果( P <0.05)。在 1~ 14 d 阶段,以混合添加沸石和EM对肉鸭体重、采食量和日增重的效果为最好( P <0.05);添加抗生素、混合添加抗生素与沸石均能明显( P <0.05)降低1~14 d樱桃谷鸭料肉比。在15~35 d阶段,添加沸石、EM、中草药均能提高肉鸭的饲料利用率,以混合添加沸石与中草药及甘氨酸微量元素螯合物效果最好,可显著( P <0.05)提高肉鸭体质量、采食量和日增重,降低料肉比。添加沸石、EM、中草药均能降低鸭舍内NH3、H2S和CO2的浓度,尤以添加沸石、甘氨酸微量元素螯合物、沸石与中草药混合物分别对降低NH3、H2S、CO2浓度效果最好。说明沸石、中草药和EM可有效提高肉鸭生长性能,降低鸭舍内有害气体浓度。

Abstract: 1600 one-day-old cherry volley ducks were randomly allocated to 8 groups and fed with different proportions and combinations of antibiotic, zeolite, Chinese herbal medicine, effective microorganisms (EM), and amino acid-trace mineral chelates, aimed to approach the effects of different additives on the duck growth performance and duck house mephitis concentration. After fed with zeolite, EM, or Chinese herbal medicine, the daily gain and feed efficiency of the ducks increased ( P <0.05) significantly. In the first 14 days, treatment zeolite + EM had the best effects on the increase of duck live weight, feed intake, and daily gain, and treatments antibiotic and antibiotic + zeolite increased the feed efficiency significantly ( P <0.05). In the late 21 days, zeolite, EM, and Chinese herbal medicine increased the feed efficiency, and zeolite + Chinese herbal medicine as well as amino acidtrace mineral chelates increased the feed intake, daily gain, and mass quality significantly ( P <0.05). Zeolite, EM, and Chinese herbal medicine decreased theNH3,H2S and CO2 concentrations in the duck house, and zeolite, amino acid-trace mineral chelates, and zeolite + Chinese herbal medicine had the best effects in reducing thetheNH3,H2S and CO2 concentrations, respectively. It was suggested that zeolite, Chinese herbal medicine, and EM could be the effective feed additives in improving the growth performance of cherry volley ducks and the available deodorizers in reducing the mephitis concentration in duck house.
