【摘要】 本文根据微生态学原理,从正常健康鲤的肠道中分离、筛选出无毒无害正常菌群Jy10、Jy31制成生态制品,作为鲤的饲料添加剂,用以饲养鲤,其应用结果表明,鲤生态制品饲养组的增重率、能量同化率、生态生长效率（K₁）,组织生长效率（K₂）以及多项生理生化指标（Rbc、Hb、血糖量、血浆总蛋白量、红细胞脆性、肌肉含蛋白质率等）均高于或优于对照组。本文对生态制品的促长作用机理进行了初步分析。更多还原

【Abstract】 This paper reported the effectiveness of microecological preparations as a promotor for growth of common carp (Cyprinus Carpio). Two living preparations contained two strains of JY10 and JY31, respectively. The strains were Lactobacillus spp. isolated from the intestine of healthy common carp. Results of the preparation feeding showed that the rates of increasing body weight, energy assimilation, ecological growth, tissue growth and other physiological and biochemical indicators(number of red blood cells, concentration of hemoglobin, plasma glucose and plasma total protein, fragitity of RBC) in test groups were all better than control groups significantly statistically.更多还原
