摘　　要：研究旨在比较分析罗氏沼虾高效饲料转化家系与原种后代的肌肉营养成分及品质。对同等养殖条件下养成的罗氏沼虾(Macrobrachium rosenbergii)十二个饲料转化家系(FF3:在"南太湖2号"的基础上运用BLUP育种技术,以饲料转化率为指标选育出的第三代家系,编号为1～12)与两个原种后代缅甸F3代(MF_3)和孟加拉F5代(BF_5)肌肉营养成分进行分析和比较。试验数据结果表明,各组之间罗氏沼虾肌肉营养含量、氨基酸组成及含量均无显著性差异(P>0.05)。应用氨基酸评分(AAS)、化学评分(CS)和必需氨基酸指数(EAAI)分别对试验虾营养价值的评定结果表明,各试验组间罗氏沼虾肌肉氨基酸营养价值无显著性差异(P>0.05)。研究证明,以饲料转化率为指标运用BLUP育种技术对罗氏沼虾进行选育不影响其肌肉的营养价值及品质。In order to compare the muscle nutritive composition and quality among efficient feed con-version families [FF3: the third generation families bred by Best Linear Unbiased Prediction (BLUP) method on the basis of "South Tailake No.2", numbered 1~12] and descendants of the wild (MF3 and BF5)Macrobrachium rosenbergii , A comparison analysis was carried out for 14 groups cultured in the same condition. The results showed that there was no significant difference in muscle nutritional com-ponent and amino acids component among these groups (P >0.05). Amino acid score, chemical score and essential amino acid index showed that there was no significant difference in amino acid nutrition-al value of muscle of Macrobrachium rosenbergii among the experimental groups (P >0.05). Research has proved that, muscle quality ofMacrobrachium rosenbergii is not affected by BLUP breeding when using feed conversion as breeding index.
