| 摘 要： | 【目的】证实复合微生物发酵饲料对商品罗非鱼养殖生长性能、成活率、饲料系数及经济效益的影响,为复合微生物发酵饲料产品的研发和应用推广提供科学依据。【方法】选用吉富罗非鱼为试验对象,分别投喂添加10%、15%、20%复合微生物发酵饲料的饵料,以基础饵料为对照,进行商品罗非鱼饲养试验和经济效益分析,并评价其应用效果。【结果】与对照相比,投喂添加10%、15%、20%微生物发酵饲料的商品罗非鱼日增重分别提高1.75%、22.14%和21.36%;成活率明显提高,分别为（96.10±0.60）%、（98.07±0.81）%和（97.67±0.63）%;饲料系数明显下降,分别降低了5.51%、15.14%和15.60%;其饲养经济效益均有提高,且以添加15%复合微生物发酵饲料所产生的单位利润最高。【结论】添加适量微生物发酵饲料养殖商品罗非鱼可促进罗非鱼生长、提高成活率、降低饲料系数和提高经济效益,且以添加15%为宜,可在广西罗非鱼养殖主产区进行示范推广。

| Abstract: | Objective]The present experiment was conducted to study the effects of compound microbial fermented feed on growth performance, survival rate, feed coefficient and economic benefits of tilapia in order to promote the application of biologically fermented feed products. Method]The bait with 10, 15 and 20% compound microbial fermented feeds was given to feed GIFT tilapia and the economic benefits and feeding effects were analyzed. The basic bait was used as control. Result]Compared to the control, the dail... |
