试验以辽宁省实用鲤鱼饲料配方为基础日粮,在试验组中添加0.1%的复合微生物制剂,池塘放养270g左右的鲤鱼,经过120d的饲养,结果表明,试验组鲤鱼的平均体质量和平均增重显著高于对照组(P<0.05)。同时试验组的饲料系数(1.78)显著低于对照组(2.15)(P<0.05),其中试验组的饲料系数比对照组下降了17.2%,同时还改善了池塘的水质指标和浮游生物的组成和数量,从而综合提高了鲤鱼的生产性能和经济效益。
The experiment was based on the diet of practical carp in Liaoning Province. The test group was supplemented with 0.1% of the composite microbial preparation, and the carp was stocked with 270 g of carp in the pond. After 120 days of feeding, the average carcass weight and average increment Remarkably higher than the control group (P <0.05). At the same time, the feed efficiency (1.78) of the experimental group was significantly lower than that of the control group (2.15) (P <0.05). The feed coefficient of the experimental group was 17.2% lower than that of the control group, and also improved the pond water quality index and plankton composition And quantity, thus improving the production performance and economic benefits of carp.
