在基础饲料中分别添加无机盐、螯合盐、麦饭石、麦饭石稀土 ,对比养鲤结果表明 :麦饭石稀土 (Ⅰ )组鲤生长最快 ,其次是螯合盐组、麦饭石稀土 (Ⅱ )组、麦饭石组、无机盐组。未添加微量元素的基础组生长最慢。方差分析表明 ,添加麦饭石的 3个试验组及螯合盐组鱼平均增重率与无机盐组差异显著 (P <0 0 5) ,与基础组差异极显著(P <0 0 1 ) ;麦饭石稀土 (Ⅰ )组与麦饭石组、无机盐组差异极显著 (P <0 0 1 ) ,与麦饭石稀土 (Ⅱ )组、螯合盐组差异不显著 (P >0 0 5)。对鲤的肌肉营养分析表明 ,螯合盐组及添加麦饭石的 3个试验组鱼肌肉中粗蛋白、粗脂肪含量都略高于基础组和无机盐组 ,但差异不显著 (P >0 0 5)。
The basic feed was added inorganic salt, chelate salt, maifanite, maifanite rare earth, contrast carp results show that: Maifanite rare earth (Ⅰ) group carps growth fastest, followed by the chelation salt group, Rare earth (Ⅱ) group, the medical stone group, inorganic salt group. The base group without trace elements grew the slowest. Analysis of variance showed that the average weight gain rate of the three experimental groups and the chelating salt group was significantly different from that of the inorganic salt group (P <0 05), and was significantly different from that of the basic group (P 0 01) (P <0.01). There was no significant difference between the rare earth (Ⅰ) group and the Maifanshi group and the inorganic salt group (P <0.01) 0 5). The muscle nutrition analysis of carp showed that the content of crude protein and crude fat in the three muscle groups of the chelated salt group and the medicated stone group were slightly higher than those of the basic group and the inorganic salt group, but the difference was not significant (P> 0 0 5).
