摘  要：
为研究用红鱼粉替代白鱼粉,并在替代饲料中添加两个不同梯度海洋红酵母对大菱鲆生长性能、体成分以及形体指标的影响。试验用白鱼粉、红鱼粉、海洋红酵母1g/kg+红鱼粉、海洋红酵母2g/kg+红鱼粉4种等氮等能的试验饲料分别饲喂初始体质量(213.48±0.23)g的大菱鲆,480尾试验鱼随机分为4组,每组设3个重复,每个重复40尾,试验期为6周。试验结果表明,与红鱼粉组相比,海洋红酵母1g/kg+红鱼粉组可显著提高大菱鲆的摄食率、相对质量增加率、特定生长率及蛋白质效率(P<0.05),效果与白鱼粉组相当,高于海洋红酵母2g/kg+红鱼粉组,但差异不显著(P>0.05)。各试验组大菱鲆的体成分和形体指标差异不显著(P>0.05)。据此,添加海洋红酵母1g/kg即能显著提高大菱鲆对红鱼粉替代白鱼粉饲料的摄食率、蛋白效率和生长性能,使得红鱼粉替代组的饲料性能达到了白鱼粉组的生长水平。

摘  要：
This experiment was conducted to investigate the effects of replacement of white fish meal by brown fish meal and two different gradients of marine yeast Rhodotorula benthica on growth performance,body composition and body indication of turbot Scophthalmus maximus.Four isonitrogenous and isoenergetic diets were formulated and contained 58% white fish meal as a control diet(W).The diet contained58%brown fish meal named B.The experimental diets(B+1,B+2)were respectively supplemented with 1g/kg,and 2g/kg the yeast on the basis of brown fish meal.Four hundred and eighty turbot with body weight(213.48±0.23)g was randomly divided into 4groups with 3replicates per group,and 40 fish per replicate for six weeks.The results showed that compared with B,addition of 1g/kg the yeast in the basis of brown fish meal significantly improved the the feeding rate,relative weight gain,the specific growth rate and protein efficiency rate of turbot(P<0.05),a similar level as W and a higher level than in B+2group(P>0.05).There were no significant difference in body composition and body indication of turbot(P>0.05).In conclusion,addition of 1g/kg into brown fish meal can significantly improved feeding rate,protein efficiency rate and growth performance of turbot,a similar growth level as white fish meal.
