| 1 | 摄食浒苔和人工饵料的点篮子鱼幼鱼肌肉营养成分比较显示文摘本试验旨在比较摄食浒苔和人工饵料的点篮子鱼幼鱼肌肉营养成分。试验选择180尾体质健壮、规格一致的点篮子鱼幼鱼,设置2个饵料组(浒苔组和人工饵料组),分别投喂浒苔鲜样和人工饵料,每组3个重复,每个重复30尾鱼,试验期90 d。结果表明:1)浒苔组点篮子鱼幼鱼的增重率、特定生长率和相对增长率均显著低于人工饵料组(P<0.05);浒苔组点篮子鱼幼鱼的粗蛋白质和粗灰分含量显著高于人工饵料组(P<0.05),而粗脂肪含量显著低于人工饵料组(P<0.05),水分含量在2组间无显著性差异(P>0.05)。2)浒苔组和人工饵料组点篮子鱼幼鱼的氨基酸组成基本一致,均检出17种氨基酸,必需氨基酸指数(EAAI)分别为76.72和70.05,其构成比例符合联合国粮农组织/世界卫生组织(FAO/WHO)的标准。3)浒苔组点篮子鱼幼鱼脂肪酸中二十碳五烯酸(EPA)+二十二碳六烯酸(DHA)和ω3多不饱和脂肪酸含量(ω3PUFA)含量均显著高于人工饵料组(P<0.05)。从以上结果可见,2组点篮子鱼幼鱼均含有多种营养成分,但从EAAI及EPA+DHA、ω3PUFA含量来看,浒苔组点篮子鱼的各种必需氨基酸和重要多不饱和脂肪酸营养均较优,摄食浒苔后的点篮子鱼味道鲜美,并具有较高的食用价值和保健作用。 | 宋超 赵峰 刘鉴毅 王妤 黄晓荣 庄平 | 2017 | 动物营养学报2017，29，6： | 9 |
| 2 | Comparison of Nutritional Components in the Muscle of Juvenile Siganus guttatus Fed with Enteromorpha prolifera and Artificial Feed显示文摘[Objective] This experiment was conducted to analyze and compare the nutritional components in the muscle of juvenile Siganus guttatus fed with Enteromorpha prolifera and artificial feed.[Method] A total of 180 healthy S.guttatus juveniles with similar body size were assigned into two groups: one fed with E.prolifera,and the other fed with artificial feed,respectively.There were three replicates in each group,and 30 fish in each replicate.And the experiment lasted for 90 d.[Result]The results showed that the weight gain rate,specific growth rate and relative growth rate of E.prolifera-fed group were significantly lower than those of artificial feed-fed group( P < 0.05); the contents of crude protein and crude ash of E.prolifera-fed group were significantly higher than those of artificial feed-fed group( P < 0.05).However,the content of crude fat of E.prolifera-fed group was significantly lower than that of artificial feed-fed group( P < 0.05).The moisture content had no significant difference between the two groups( P > 0.05).The amino acid composition was similar between the two groups.Seventeen amino acids were found in both groups,and the essential amino acid index( EAAI) was 76.71 in E.prolifera-fed group and 70.05 in artificial feed-fed group,both of which met the criteria set by the Food and Agriculture Organization of the United Nations( FAO)/World Health Organization( WHO).The content of eicosapentaenoic acid( EPA) + docosahexaenoic acid( DHA) and the content of ω-3 polyunsaturated fatty acids( ω-3 PUFAs) of E.prolifera-fed group were significantly higher than those of artificial feed-fed group( P < 0.05).[Conclusion]In conclusion,the juvenile S.guttatus in both groups contains a variety of nutritional components.S.guttatus fed with E.prolifera has higher levels of essential amino acids,more balanced composition of polyunsaturated fatty acids,higher nutritive value and better taste than that fed with artificial feed. | Song Chao Zhao Feng Liu Jianyi Wang Yu Huang Xiaorong Zhuang Ping | 2017 | Animal Husbandry and Feed Science2017，9，6： | 0 |
