摘要
为了解4种复方中草药对鲤Cyprinus carpio生长性能及其体成分的影响,将用不同组成和配比制备的4种复方中草药,以质量分数为3‰的量分别添加到鲤基础饲料中,试验分为对照组和4个中草药组,复方1由板蓝根、大黄组成,复方2由黄芪、黄柏等组成,复方3由辣蓼、青蒿等组成,复方4由甘草、大黄、五倍子组成,每组3个重复,每个重复放体质量为(15.26±3.95)g的鲤30尾,养殖试验共进行30 d。结果表明:2号和4号复合中草药的使用对鲤生长有一定的促进作用,而1号复合中草药组促生长效果不理想;各组复合中草药的使用不同程度地降低了鲤饲料系数;各复方中草药组鲤粗蛋白质含量略高于对照组,但无显著性差异(P>0.05);各复方中草药组鲤氨基酸含量均高于对照组,仅2号复方中草药组显著高于对照组(P<0.05),其他各组间无显著性差异(P>0.05),2、3、4号复方中草药组鲜味氨基酸含量均高于对照组,但无显著性差异(P>0.05);各复方中草药组鲤脂肪酸含量与对照组无显著性差异(P>0.05)。研究表明,饲料中添加适宜的复方中草药不仅可以促进鱼类生长,降低饲料系数,而且可以提高鱼肉蛋白质和氨基酸含量,改进氨基酸组成配比,提高鲜味氨基酸含量,改善鱼体的肌肉品质和口感。
Juvenile common carp Cyprinus carpio with initial body length of(15.26±3.95)g were reared in a 55 cm× 55 cm×110 cm net cage disposed in a tank at a density of 30 ind./net and fed four diets containing 3‰ of Chinese herbal medicine compounds including Radix isatidis and Chinese rhubarb (group 1), Astragalus membranaceus and golden cypress (group 2), medicated leaven and Artemisia annua (group 3), licorice and Rheum palmatum (group 4) and without Chinese herbal additive (group 5, as control group) with triplication for 30 days to investigate effects of Chinese herbal medicines on growth performance and body composition of common carp. The results showed that good growth was observed in the fish in group 2 and group 4, and poor growth in the fish in group 1. There was lower food conversion ratio (FCR) in the fish fed the diets containing Chinese herbal medicine compounds compared with that in the control group. The fish fed the diets containing Chinese herbal medicine compounds had higher crude protein levels than the fish fed the control diet did, without significance ( P > 0.05 ). Fish fed diet 2 had the significantly higher total amino acid levels( P <0.05)than the fish in the control group did, without significant difference mong the other groups( P > 0.05 ). There were higher flavor amino acid levels in the fish fed diets 2, 3 and 4 than that in the fish fed the control diet, without significant difference( P >0.05). No significant difference in crude fat level was found among each group( P >0.05). The findings indicate that appropriate supplemental amount of Chinese herbal additives leads to some extent to improve the growth performance and muscle quality, and to reduce FCR in fish to some extent.
