微量元素添加剂形态对皱纹盘鲍生长的影响

EFFECTS OF DIFFERENT FORMS OF TRACE ELEMENTS ON THE GROWTH OF ABALONE ( HALIOTIS DISCUS HANNAI INO)

在鲍鱼基础饲料中 ,分别添加无机盐、氨基酸微量元素螯合盐、麦饭石等 ,对皱纹盘鲍 (HaliotisdiscushannaiIno)的幼鲍进行喂养试验表明 ,添加螯合盐幼鲍生长最快 ,麦饭石其次 ,无机盐及对照生长最差。鲍的体重增长率 ,螯合盐与无机盐和对照的差异极显著 ,麦饭石与对照、螯合盐与麦饭石的差异显著 ,麦饭石。

To the basal feed of abalone ( Haliotis discus hannai Ino) were added MF (granite powder), inorganic salts or chelates of amino acids and trace elements at different rates. The growth rate of the young abalones was highest in the chelate group, followed by the MF group and the inorganic salt group, and lowest in the control group where no trace elements were added. Variance analysis showed that the difference in average growth gain rate was highly significant between the chelate group and the control, significant between the MF group and the control and between the chelate group and the MF group, and insignificant between the MF group and the inorganic salt group.
