| 摘 要： | 选取平均体重为182.33 g ·尾^-1的新吉富罗非鱼216尾分成6组，分别设试验组1号（添加蚕豆醇提物）、2号（添加蚕豆酮提物）、3号（添加蚕豆酯提物）、4号（添加大豆异黄酮）、5号（添加大豆皂甙）、对照组6号（基础料），每组设3个重复，比较不同提取物对罗非鱼生长速度、饲料效率、肌肉营养成分及脆化度的影响。经过60 d的饲养，结果表明：各组在生长性能各指标上差异不显著（ P＞0.05）。在肌肉品质方面，1号、5号罗非鱼肌肉水分含量降低，粗蛋白含量、粗灰分含量提高，差异不显著（ P＞0.05）；而粗脂肪含量、胶原蛋白含量、肌原纤维耐折力显著提高（P＜0.05），肌肉滴水损失显著降低（P＜0.05）。综合以上分析，蚕豆醇提取物和大豆皂甙在一定程度上脆化了罗非鱼肉质，蚕豆醇提物起肉质脆化作用的可能是皂甙类成分。

| Abstract: | 216 healthy Tilapia were randomly divided into six groups ,and three replication were set within each group ;the feed additives for the groups were broad bean alcohol extracts （No .1） ,broad bean ester extracts （No .2） ,broad bean acetone extracts （No .3） ,soy isoflavone （No .4） ,soy asaponin （No .5） and blank （No .6 ,basic diets as control） respectively .After 60 days feeding with the experimental diets , effects of different feed additives on growth , feed conversion ratio and muscle quality of Tilapia were examined . The results showed no significant effect on growth performance （P〈0.05） ,while the muscle quality analysis indicated that in the case of group 1 and group 5 ,water content and protein content decreased and ash content increased slightly （P〈0.05）;but lipid content ,collagen content and length of myofibril increased obviously （P〉0.05） ,and drip loss decreased significantly （P〈0.05） .In conclusion ,broad bean alcohol extracts and soy asaponin feed both embrittled the Tilapiamuscle ,and probably the asaponin ingredient from broad bean alcohol extracts played an important role in embrittlement . |
