摘　　要：选取来源一致、规格整齐、体质健康、游动活泼的团头鲂750尾,随机分为5个处理,每处理3个重 复,每重复50尾,分置于15个网箱中。各处理全价配合饲料中苜蓿草粉的添加量依次为:0(对照组),100(试验Ⅰ 组),200(试验Ⅱ组),300(试验Ⅲ组)和400 g／kg(试验Ⅳ组),正试期40 d。测定团头鲂的生长、体型指标、肌肉营养 成分及经济效益,研究不同水平苜蓿草粉对团头鲂生长性能及肉品质的影响。结果表明:(1)与对照组相比,试验Ⅰ 组团头鲂尾均日增重提高,饵料系数降低,其中尾均日增重在试验后期,饵料系数无论是试验前期、后期还是整个 试验期均呈现出显著性差异(P<0．05);试验Ⅰ组和试验Ⅱ组团头鲂生长速度较对照组有一定提高,但差异不显著 (P>0．05)。(2)试验Ⅰ组和试验Ⅱ组的团头鲂肥满度、体型均优于对照组,但差异不显著(P>0．05)。(3)试验Ⅰ组 肌肉粗蛋白质含量高于对照组(P>0．05),各试验组粗脂肪含量有逐渐低于对照组的趋势,其中试验Ⅲ、Ⅳ组显著 低于对照(P<0．05),说明适量添加苜蓿草粉有助于提高鱼肉品质。(4)苜蓿草粉添加量为100 g／kg的经济效益较 对照组显著提高(P<0．05)。An experiment was conducted using 750 Megalobrama amblycepnala to study the effect of alfalfa meal on production performance and qulity of fish. They were randomly divided into five treatments according to a random factorial arrangement,and each treatment represented by three replicates of 50 carps each. Carps were fed diet with 0,100,200,300 and 400 g/kg alfalfa meal during the phrase of 40 days. The results showed that （1）100 g/kg alfalfa meal in diet were superior in average individual daily weight gain and feed conversion ratio than that of no meal treatment （P〈0. 05）,but average individual daily weight gain,relative growth rate and feed conversion rate of bluntnose black breams fed alfalfa meal at 300 g/kg and 400 g/kg in diet significantly decreased（P〈0.05）. Relative growth rate also showed that 100 g/kg alfalfa meal had more active effect on production performance than that of no meal treatment ,although between the two groups showed no significant differences （P〉0.05）. Bluntnose black breams added 200 g/kg alfalfa meal were inferior to that of no meal treatment ,but the two groups there were no significant differences too（P〉0. 05）. （2）The relative fatness and ratio of body length and height of group Ⅰ and Ⅱ were superior to that of no meal treatment, however, among three groups there were no significant differences （P〉0.05）. （3）According to no meal treatment,crude protein content of muscle was improved in group Ⅰ than control group,but no significant differences were shown（P〉0. 05）. EE was significantly decreased when the amount of alfalfa meal was increased（P〈0.05）,especially group Ⅲand Ⅳ. It showed that alfalfa meal can improve the qulity of fish body of carps. （4）Economic profit of carps fed diets with 100 g/kg alfalfa meal was best. So it is recommended that 100 g/kg is suitable additive amount of alfalfa meal in diet of bluntnose black breams.
