摘要
本试验主要研究以不同方法提取复合中草药中的有效成分和直接利用复合中草药作为饲料添加剂对蛋雏鸡前期生长性能及体成分的影响。结果表明:以麦芽、松针粉、胡萝卜、陈皮、石膏组成的复方中草药的不同提取方法制备的提取液及原粉剂,极显著提高日增重(P<0.01)和显著提高料肉比(P<0.05)。按文中各种添加剂的研究顺序,日增重分别提高3.04、2.32、2.53、2.53、3.75g。在主要养分表观利用率和沉积率上添加剂组优于对照组且差异显著(P<0.05),且各添加剂组彼此存在差异。
In this paper the effect of Chinese harbal medicine and its active ingredierts extracted by different methods on growth performance and body composition of layers were studied. The results showed that the compound Chinese herbal medicine powder and its extracts composed of malt,pine,needle powder,carrots,dried tangerine peel and gypsum could increase daily gain very significantly and increase feed conversion significantly. The daily gain increased 3.04,2.32,2.53,2.53,3.75 g respectively. Apparent utilization of main nutrition and deposition rate of suppliment groups were better than control group(P〈0.05),and there were differences among suppliment groups.
