添加微量元素的各试验组均优于对照组。等量添加氨基酸微量元素、多糖酸微量元素 ,明显优于无机微量元素。氨基酸微量元素的增重率和饲料转化率比无机微量元素分别提高 8 8%、10 2 % ;多糖酸微量元素的增重率和饲料转化率比无机微量元素分别提高 5 9%、3 7%。氨基酸微量元素与多糖酸微量元素对鲤鱼增重率及饲料转化率的影响无显著差异。在本试验条件下 ,每千克饲料添加多糖酸微量元素Fe 15 0mg、Cu 3mg、Zn 30mg、Mn 13mg是适宜的。
Each test group added trace elements were better than the control group. The same amount of amino acid trace elements, polysaccharides, trace elements, significantly better than inorganic trace elements. The weight gain rate and feed conversion rate of amino acid trace elements increased by 8 8% and 102% respectively compared with that of inorganic trace elements. The weight gain rate and feed conversion rate of micronutrient micronutrients increased by 59% and 37% . There were no significant differences in amino acid trace elements and polysaccharides of trace elements on carp weight gain rate and feed conversion rate. Under the experimental conditions, it is appropriate to add the polysaccharide acid Fe 15 0mg, Cu 3mg, Zn 30mg and Mn 13mg per kg of feed.
