摘  要：
试验研究饲粮添加不同水平的果寡糖(FOS)对奥尼罗非鱼(Oreochromis niloticus×O.aureus)生长性能、血清生化指标和肠道菌群的影响。选用体重10 g左右的奥尼罗非鱼540尾随机分成6个组,每组3个重复,每个重复30尾。在基础饲粮中分别添加0%(对照组)、0.1%、0.2%、0.3%、0.4%、0.5%的FOS,进行为期8周的饲养试验。结果表明,与对照组比较,0.4%FOS组和0.5%FOS组的奥尼罗非鱼相对增重率分别显著提高24.45%(P<0.05)和28.27%(P<0.05),饵料系数分别显著降低13.87%(P<0.05)和18.98%(P<0.05)。与对照组比较,添加FOS组鱼血清TG、GLU、GLO、AST、ALT、LDH和ALP无显著差异(P>0.05);血清总蛋白、白蛋白含量呈上升趋势,其中0.4%FOS和0.5%FOS组显著提高(P<0.05);肠道双歧杆菌、乳酸杆菌数显著增加(P<0.05),大肠杆菌、沙门氏菌数显著降低(P<0.05)。综上所述,饲粮添加FOS可改善奥尼罗非鱼生长性能,增加鱼肠道有益菌,降低有害菌数量,其中FOS的适宜添加量为0.4%~0.5%。

摘  要：
The present experiment was conduct-ed to investigate the effect of fructooligosaccha-ride(FOS)on the growth performance,serum bio-chemical indices and intestinal microflora of hy-brid tilapia(Oreochromis niloticus × O.aureus).540 tilapias about 10 g in initial body weightwere selected and randomly divided into sixgroups with three repeats for each group, thirtyeach repeats. Diets adding 0%(control group),0.1%,0.2%, 0.3%,0.4% and 0.5% FOS were fed respectively for 8 weeks. The results showed that rel-ative weight gain rates of tilapias were significantly increased 24.45%(P<0.05) and 28.27%(P<0.05),FCR were significantly decreased 13.87%(P<0.05) and 18.98%(P<0.05) respectively in diets adding0.4% FOS and 0.5% FOS comparing with control group. There were no significant difference in serumTG, GLU, GLO, AST, ALT, LDH and ALP in FOS groups compared with the control group(P>0.05).With the increase of fructooligosaccharide, serum total protein and albumin contents increased, amongthem, serum total protein, albumin contents were significantly higher than control group in diets add-ing 0.4% FOS and 0.5% FOS(P<0.05). Intestinal bifidobacterium, lactobacillus in 0.4% FOS, 0.5%FOS group were significantly increased comparing with the control group, and E. coli, Salmonella, sig-nificantly lower than the control group(P<0.05). The FOS of propriate dosage in diet is suggested tobe 0.4%~0.5% for tilapia(Oreochromis niloticus×O.aureus).
