【摘要】 设计了6个不同微生态制剂水平(0％,1．0％,2．0％,3．0％,4．0％,5．0％)的饲料,对石斑鱼幼鱼(11．8±0．2)g进行了为期28 d的生长实验。结果显示:实验组饲料对石斑鱼的成活率、特定生长率(SGR)、饲料转化率和蛋白质效率均优于对照组, 初步认为添加2．0％-4．0％比较有利于石斑鱼的生长和饲料的利用。更多还原

【Abstract】 A 4-week trial was conducted to study the effects of dietary probiotic levels on growth and feed utilization of juvenile grouper initial weight(11.8±0.2)g.The fish were fed to satiation with six diets containing 0%,1.0%,2.0%,3.0%,4.0% and 5.0% probiotic levels, repectively.The result showed that higher special growth rate,feed conversion ratio and protein efficiency ratio were obtained when dietary probiotic was 2.0,3.0 and 4.0 than the control.更多还原
