摘  要：
试验研究饲料中异亮氨酸(Isoleucine,Ile)和缬氨酸(Valine,Val)的交互作用对牙鲆(Paralichthys olivaceus)肠道消化酶及肝脏免疫相关酶活力的影响。设2个异亮氨酸(Ile)水平(分别占饲料干物质的0%和2%),并将其分别与3个缬氨酸(Val)水平(分别占饲料干物质的0%、0.83%和2.27%)制成6组试验饲料(LI-LV、LI-MV、LI-HV、HI-LV、HI-MV、HI-HV)。以初始体重为(3.57±0.05)g的牙鲆为研究对象,随机分为6个处理组,每个处理组设3个平行,每个平行放20尾鱼,分别投喂上述6种试验饲料,试验期为60 d。结果表明,低Ile水平时,蛋白酶和淀粉酶活性随Val水平的增加先升高后下降,脂肪酶活性随之显著降低(P<0.05),总抗氧化能力(T-AOC)与超氧化物歧化酶(SOD)活力随Val含量的增加而显著下降(P<0.05),而过氧化氢酶(CAT)活力则先升高后降低,碱性磷酸酶(AKP)则先降低而后升高;但在高Ile水平时,脂肪酶、SOD活力随饲料Val含量的增加而显著升高(P<0.05)。双因素方差分析结果表明,Ile和Val之间存在交互作用,且在Ile 2%与Val 2.27%水平下,牙鲆幼鱼脂肪酶、超氧化物歧化酶、碱性磷酸酶活力均达到最高值。故Ile与Val对牙鲆体组织消化酶和免疫酶有显著交互作用,并且Ile 2%与Val 2.27%交互作用时显著提高牙鲆脂肪酶、超氧化物歧化酶活性。

摘  要：
A feeding trail was conducted to investigate the interactive effect of dietary isoleucine(Ile)and valine(Val) on activities of intestine digestive enzymes and several liver immune related en-zymes of juvenile Japanese flounder Paralichthys olivaceus. Japanese flounder juveniles were fed sixdiets(LI-LV, LI-MV, LI-HV, HI-LV, HI-MV, HI-HV) containing two levels of dietary Ile(0%,2%in dry matter) combined with three levels of dietary Val(0%, 0.83%, 2.27% in dry matter). Japaneseflounder juveniles with initial weights of(3.57 ± 0.05) g were randomly divided into 6 treatmentgroups. With triplicate tanks per treatment, per tanks was placed 20 fish which were fed 60 days.The results showed that: At low Ile levels, protease and amylase activity increased first and then de-creased with the increase of Val level, and the activity of lipase decreased significantly(P<0.05). Theactivity of T-AOC and SOD decreased significantly with the increase of Val content(P<0.05), whilethe CAT increased first and then decreased,while alkaline phosphatase(AKP) decreased firstand then increased; but at high Ile level, thevigor of lipase, SOD promoted obviously withthe increase of Val content(P<0.05). The re-sults of two factor variance analysis showed that there was interaction between Ile and Val, and the activity of lipase, superoxide dismutase and alka-line phosphatase in juvenile flounder was the highest at the level of Ile 2% and Val 2.27%. Ile andVal had significant interaction with the digestive enzymes and immune enzymes in Paralichthys oliva-ceus, and the interaction of Ile 2% and Val 2.27% significantly improved the activity of lipase andsuperoxide dismutase.
