本研究按均匀设计，在相同基础饵料中分别添加不同含量的多糖、Ｆｅ、Ｃｕ、Ｚｎ、Ｍｎ络合物及相当含量的无机微量元素。在相同饲养条件下试喂一冬龄建鲤３０天。结果表明：多糖微量元素络合物对建鲤的相对生长率、饵料系数、耐低氧能力都比无机微量元素好。其中试验Ⅱ组较优，其相对生长率为２１６５％，饵料系数为２４４，耐低氧持续时间为７７３３小时。在这种基础饵料和饲养条件下，添加４种多糖微量元素，优选组合是Ｃｕ５５μｇ／ｇ、Ｆｅ１８０μｇ／ｇ、Ｚｎ１１０５～１４０μｇ／ｇ、Ｍｎ６５μｇ／ｇ，其相对生长率可达３１４２７％，饵料系数为１９７８８，差异均极显著 According to the uniform design, different amounts of polysaccharides, Fe, Cu, Zn and Mn complexes and a considerable amount of inorganic trace elements were added to the same basal diet. Under the same feeding conditions, try to feed a winter carp Jian 30 days. The results showed that the relative growth rate, feed conversion coefficient and hypoxia tolerance of polysaccharide trace element complexes to Jian carp were better than inorganic trace elements. The experimental group Ⅱ was superior, the relative growth rate was 2165%, the feed coefficient was 244, and the duration of hypoxia tolerance was 773 hours. Under this kind of basic food and feeding conditions, four kinds of polysaccharide trace elements were added, the relative growth rate was 31.427%, and the optimal combination was Cu55μg / g, Fe180μg / g, Zn1105-140μg / g, Mn65μg / g, , Bait coefficient was 19788, the difference was extremely significant
