近年来国内外有关大菱鲆营养与饲料方面的研究表明,合适的日粮营养水平可显著提高鱼类对饲料的嗜好性,提高饲料的利用率,促进鱼类的生长。因此试验以威海等近海的经济鱼种大菱鲆即多宝鱼,作为试验的研究对象,分别将复方中草药提取液、L-甘氨酸和干浒苔粉按一定添加量加入到基础饲料中制成3种新型配方饲料,采用摄食率法和迷宫法作为试验方法,结果表明:复方中草药提取液、L-甘氨酸和干浒苔粉的诱食效果都具有显著的统计意义(P<0.05)。其中浒苔工艺处理组增重率最高;复方中草药提取液添加剂组饲料系数最小,这2组均好于L-甘氨酸组和对照组,具有一定的应用意义。
In recent years, domestic and international research on nutrition and feed of turbot shows that proper dietary nutrition can significantly improve the preference of feed for feed, improve the utilization of feed and promote the growth of fish. Therefore, the test to Weihai and other coastal species of turbot turbot that multi-fish, as the test subjects, respectively, the compound Chinese herbal medicine extract, L-glycine and dry Enteromorpha added by a certain amount of basic feed made of The results showed that the attractant effects of compound Chinese herbal medicine extract, L-glycine and dried enteromorpha powder all had significant statistical significance (P <0.05). Among them, Enteromorpha prolifera treatment group had the highest rate of weight gain; Compound Chinese herbal medicine extract group had the lowest feed coefficient, both groups were better than L-glycine group and control group, which had some practical significance.
