| 摘 要： | 在基础配合饲料中添加0.5%、1%、2%、4%抗菌脂肽,饲养瓦氏黄颡鱼8周,对其肌肉一般营养成分、氨基酸营养、脂肪酸营养进行分析比较。结果表明抗菌脂肽对瓦氏黄颡鱼肌肉蛋白质、灰分含量无显著影响(P0.05)。瓦氏黄颡鱼是氨基酸组成均衡性较好(EAAI75、EAA/NEAA79%)的优质水产品,富含Glu、Asp、Arg等有助于术后病人康复的氨基酸。Lys含量较为富余,适当摄入可平衡谷物中Lys短缺,第一限制性氨基酸为Met+Cys。4%范围内添加抗菌脂肽对瓦氏黄颡鱼氨基酸组成无显著性影响(P0.05),EAAI随着AMI添加量增加逐渐降低,但仍高于75%。瓦氏黄颡鱼肌肉脂肪酸主要组成种类不少于11种,其中饱和脂肪酸3种、单不饱和脂肪酸4种、多不饱和脂肪酸4种,不饱和脂肪酸相对含量均较高,富含多不饱和脂肪酸(二十碳四烯酸、EPA、DHA)。在4%添加范围内,抗菌脂肽对瓦氏黄颡鱼肌肉脂肪酸组成无明显影响。

Effect of Antimicrobial Lipopeptides in Fishmeal on Nutritional Composition of Meat from Darkbarbel Catfish (Pelteobagrus vachelli) |

| Abstract: | Effect of antimicrobial lipopeptides (AML)in fishmeal on the nutritional composition of the meat from Darkbarbel catfish (Pelteobagrus vachelli )was studied.Five diets incorporated with 0,0.5,1,2,and 4% of AML were used to feed randomly selected 4 groups of fish comprising 20 individuals each for 8 weeks.The amino acids and fatty acids in the fish muscles were analyzed.The results showed no significant differences in protein or ash contents among the fish fed with the varied amounts of AML (P >0.05 ).On the other hand,the fish meat was considered of high-quality protein according to FAO/WHO standards.The greatest amount of amino acid in the meat was Glu,followed by Asp and Arg.The rich content of Lys was ideal to supplement grains for human nutritional need.AML did not show any significant effect on the amino acid contents (P > 0.05 ).The fish meat contained more than 1 1 kinds of fatty acids,including 3 saturated,4 monounsaturated,and 3 polyunsaturated fattyacids.There was no significant differences on the fatty acid contents found in meat from the fish fed on diets with 5 different AML levels either. |
