| 1 | 茶多酚对奥尼罗非鱼生长、消化功能、免疫性能和抗病力的影响显示文摘本试验旨在研究茶多酚对奥尼罗非鱼(Oreochromis niloticus×O.aureus)生长、消化功能、免疫性能和抗病力的影响。在基础饲料中分别添加0(对照组)、100、200、400、600、800 mg/kg茶多酚,配制6种试验饲料,饲喂初始体重为(6.09±0.07)g的奥尼罗非鱼9周,每组3个重复,每个重复25尾鱼。结果表明:与对照组相比,各茶多酚添加组的增重率和饲料系数均无显著变化(P>0.05),但100、200 mg/kg茶多酚组增重率有提高的趋势,而400~800 mg/kg茶多酚组增重率有降低的趋势,其中以200 mg/kg茶多酚组增重率最高。饲料添加茶多酚对罗非鱼全鱼水分、粗蛋白质、粗灰分含量和粗蛋白质表观消化率无显著影响(P>0.05),但与对照组相比,高添加量(600、800 mg/kg)的茶多酚显著降低了干物质表观消化率,肠道淀粉酶、蛋白酶活性和全鱼粗脂肪含量(P<0.05)。与对照组相比,饲料中添加200、400、600和800 mg/kg茶多酚均显著增加了血清超氧化物歧化酶(SOD)和溶菌酶(LZM)活性(P<0.05),而血清丙二醛(MDA)含量则随茶多酚添加量的增加表现出先降低后增加的趋势,其中200 mg/kg茶多酚组的血清SOD活性最高、血清MDA含量最低,400 mg/kg茶多酚组的血清LZM活性最高。嗜水气单胞菌攻毒后48和96 h,200、400、600和800 mg/kg茶多酚组的累积死亡率均较对照组显著降低(P<0.05),其中400 mg/kg茶多酚组的累积死亡率最低。综上,茶多酚可提高奥尼罗非鱼的免疫性能,降低嗜水气单胞菌攻毒后的死亡率,但对生长性能没有显著影响。奥尼罗非鱼饲料中茶多酚的建议添加量为200~400 mg/kg。 | 梁高杨 李小勤 杨航 POOLSAWAT Lumpan 高擘为 冷向军 | 2018 | 动物营养学报2018，30，8： | 18 |
| 2 | Efficacy of phytogenic extracts on growth performance and health of tilapia (Oreochromis niloticus × O. aureus)显示文摘The present study was conducted to evaluate the efficacy of phytogenic extract on growth and health of tilapia.Three experimental diets were designed as the basal diet(Con)and phytogenic extract(Flourishing,F)supplemented diets at 0.5 and 1 g/kg inclusion(F-1 and F-2),which the phytogenic additive was extracted from Eucommia ulmoides,Astragalus membranaceus,Lonicera japonica and Codonopsis pilosula.The three diets were fed to juvenile tilapia(14.0±0.1 g)with 30 fish per cage,and three replicate cages from the three groups were placed in one indoor concrete pool(a total of three pools were used).After 8 weeks of feeding,the weight gain was significantly increased,and feed conversion ratio was decreased in F-2 group(P<0.05)when compared to the control.Both levels of phytogenic extract significantly promoted the retentions of protein and lipid and the apparent digestibility coefficient of dry matter and protein(P<0.05).The activity of superoxide dismutase and the levels of white blood cells,haemoglobin and glutamic pyruvic transaminase were also significantly increased by the supplementation of phytogenic extract(P<0.05).The villus height in anterior intestine was significantly enhanced in F-1 and F-2 groups(P<0.05).After challenging with Aeromonas hydrophila,the cumulative mortality was significantly declined in F-1 and F-2 groups(P<0.05).In summary,the dietary supplementation of phytogenic extract at 1 g/kg feed could provide positive efficiency on growth,nutrient utilization,immunity,gut morphology and disease resistance of tilapia under the present conditions. | Lumpan Poolsawat Yifeng Yu Xiaoqin Li Xu Zhen Wenxiang Yao Pu Wang Congyan Luo Xiangjun Leng | 2022 | Aquaculture and Fisheries2022，7，4： | 0 |
