Application of compound microbial fermented feeds on tilapia breeding
摘要
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 daily average weight increment of tilapia fed with 10, 15 and 20% compound microbial fermented feed increased by 1.75, 22.14 and 21.36%, respectively, and the survival rate increased by 96.10± 0.60, 98.07±0.81 and 97.67±0.63%, respectively, while their feed coefficient decreased by 5.51, 15.14 and 15.60%. All the treatments showed higher economic benefits compared to control, however, the bait mixed with 15% compound microbial fermented feed gave highest unit benefit. [ Conclusion ]Adding suitable microbial fermented feed in bait in tilapia breeding could promote the growth, enhance the survival rate, decrease the feed coefficient and increase the economic benefits. The bait mixed with 15% compound microbial fermented feed may be used in demonstrations and recommended in main tilapia breeding regions of Cuangxi.关键词
