| 摘 要： | 研究了大豆浓缩蛋白(SPC)替代鱼粉对大菱鲆生长及生理生化指标的影响。5种饲料分别含有0、12.0%、25.0%、37.0%和49.5%的SPC以替代相应的鱼粉,并分别添加0、0.83%、1.65%、2.48%和3.30%的必需氨基酸混合物(L-lysine∶DL-methionine∶L-leucine∶Lvaline∶L-threonine=18∶6∶3∶2.5∶2)以平衡各组饲料的氨基酸组成。每种饲料投喂3个水族箱(300 L),每个水族箱放养实验鱼16尾,实验鱼初始体质量为(31.1±0.1)g。经过9周生长实验,结果显示随着饲料中SPC替代水平的升高,大菱鲆摄食率、特定生长率均显著下降(P0.001)。然而,当使用0~37.0%的SPC替代鱼粉时,各处理组饲料效率和蛋白质效率未出现显著差异(P0.05)。饲料中SPC替代鱼粉对大菱鲆鱼体水分、粗蛋白、粗脂肪及灰分含量均无显著影响(P0.05)。各处理组干物质和粗蛋白的表观消化率之间也未出现显著差异(P0.05)。研究表明,在本实验条件下SPC不能作为大菱鲆饲料中替代鱼粉的有效蛋白源,造成SPC替代效果较差的主要原因是其对大菱鲆饲料适口性的显著影响。

| Abstract: | This study evaluated the effects of fish meal replacement with soy protein concentrate(SPC)on feed intake,growth and nutrient utilization of turbot,Scophthalmus maximus.Five experimental diets were formulated,in which FM protein was replaced by SPC at 0,12%,25%,37%(S75)and 49.5%,respectively.Five diets were supplemented with 0,0.83%,1.65%,2.48% and 3.30% essential amino acid mixture(L-lysine:DL-methionine:L-leucine:L-valine:L-threonine=18:6:3:2.5:2).Each diet was randomly assigned to triplicate groups of fish,and each group was stocked with 16 turbot with an initial weight of (31.1±0.1)g] in 15 fiberglass tanks(300 L).Fish were fed twice daily(8:30 and 17:00)to visual satiation for 9 weeks.At the end of the growth experiment,feed intake(FI)(P<0.001)and specific growth rate(SGR)(P<0.001)decreased linearly with increasing dietary SPC levels.There were no significant differences(P>0.05)in feed efficiency ratio(FER)and protein efficiency ratio(PER)among fish fed diets with 0-37%SPC.Apparent digestibility coefficients of dry matter and crude protein of the diets were not significantly(P>0.05)affected by dietary treatments.These results indicate that protein from SPC could not effectively replace FM protein in diets of turbot because of lower feed intake. |
