This research evaluated the effects of copper(Cu)on intestinal antioxidant capacity and apical junctional complex(AJC)in juvenile grass carp.A total of 1080 healthy juvenile grass carp(11.16±0.01 g)were fed six diets including different dosages of Cu,namely 0,2,4,6,8 mg/kg(Cu citrate[CuCit]as Cu source)and 3 mg/kg(CuSO4·5H2O as Cu source).The trial lasted for 9 *** findings revealed that dietary optimal Cu supplementation(2.2 to 4.1 mg/kg)promoted intestinal growth,including intestinal length,intestinal length index,intestinal weight,and intestinal somatic index(P 0.05).On the other hand,optimal Cu increased intestinal tight junction(TJ)proteins(except for claudin 15b)and adherens junction(AJ)proteins(E-cadherin,α-catenin,β-catenin,nectin and afadin)mRNA levels(P<0.05),which could be connected to the signaling pathway formed by the Ras homolog gene family,member A(RhoA),Rho-associated kinase(ROCK),and myosin light chain kinase(MLCK).Finally,based on serum indicator D-lactate and intestinal oxidative damage index(ROS),Cu requirement(CuCit as Cu source)for juvenile grass carp from initial weight to final weight(from 11 to 173 g)was determined to be 4.14 and 4.12 mg/kg diet,*** work may provide a theoretical foundation for identifying putative Cu regulation pathways on fish intestinal health.
