芒果叶黄酮浸膏促进大菱鲆生长的研究

Study ongrowth promotion of Scophthalmus maximus by mango leaf flavone extract

该试验以大菱鲆(Scophthalmus maximus)为试验对象,研究芒果叶黄酮浸膏对大菱鲆生长的影响。试验选择一批大小接近、健康度良好的大菱鲆幼苗,共100尾,进行随机分组,分为对照组和试验组两组,每组50尾,对照组饲喂基础日粮,试验组饲喂添加7%芒果叶浸膏的基础日粮,试验期30d,试验过程记录每尾大菱鲆的初始平均体重、试验末期平均体重、存活尾数、初始平均体长、试验末期体长,通过计算成活率、质量相对增长率、饲料系数、体长增重率来判断芒果叶黄酮浸膏促进大菱鲆生长的作用。试验结果显示,添加芒果叶黄酮浸膏组的质量增长率、成活率和对照组相比差异显著(P<0.05),试验组的体长增长率与对照组比也有增长的趋势,但是差异不显著(P>0.05)。研究表明,芒果叶浸膏能促进大菱鲆体重增长、提高其成活率,对其生长起到促进作用。

In this study,the effects of mango leaf flavone extract on the growth of Scophthalmus maximus were studied.A total of 100 Scophthalmus maximus seedlings with similar size and good health were selected and randomly divided into control group and experimental group,with 50 seedlings in each group.The control group was fed the basal diet,and the experimental group was fed the basal diet supplemented with 7% mango leaf extract.The experiment lasted for 30 days.During the experiment,the initial average body weight,the average body weight at the end of the experiment,the number of surviving tails,the initial average body length and the body length of each tail were recorded.The study on the promotion of growth of Scophthalmus maximus by mango leaf flavonoid extract was judged by calculating the survival rate,mass relative growth rate,feed conversion ratio and body length gain rate.The results showed that the mass growth rate and survival rate of the mango leaf flavonoid extract group were significantly different from those of the control group(P<0.05).Compared with the control group,the growth rate of body length in the experimental group also showed an increasing trend,but the difference was not significant(P>0.05).The results showed that mango leaf extract could promote the weight gain and survival rate of Scophthalmus maximus,and improve the survival rate and promote the growth of Scophthalmus maximus.
