DIETARY ARGININE ON GROWTH AND MUSCLE QUALITY OF SONGPU MIRROR CARP(CYPRINUS CARPIO SONGPU)IN MID-GROWTH STAGE
摘要
Abstract
The study assessed the impact of dietary arginine supplementation on the growth performance,feed effi-ciency,muscle attributes,and antioxidant potential of Songpu mirror carp(Cyprinus carpio Songpu)during the mid-growth stage.Six semi-refined diets containing 28.11%crude protein were formulated with dietary arginine levels of 0.71%,1.06%,1.41%,1.76%,2.11%,and 2.46%.Each diet was fed to three replicate groups of carp with an initial body weight of(298.89±15.30)g for 56d.Results indicated that the weight gain rate(WGR),specific growth rate(SGR),and protein efficiency ratio(PER)exhibited an initial increase followed by a decrease as arginine levels in the feed rose,with the most pronounced enhancement occurring at 1.41%arginine.Conversely,the feed conversion ratio(FCR)demonstrated an opposite trend,showing significantly lower FCR(P<0.05)in the 1.41%group compared to the other groups except the 1.76%group.In the 1.41%arginine group,value in hardness,elasticity,chewiness,and shear force metrics were superior to the other groups.Furthermore,water loss rates for centrifugation and cooking in the 1.41%arginine group were the minimal and centrifugation water loss was significantly lower than those in the 0.71%and 2.46%groups(P<0.05).However,cooking loss rates did not vary significantly amongst groups(P>0.05).Myofi-bre diameter was notably reduced(P<0.05)in the 1.41%arginine group compared to those with 0.71%,2.11%,and 2.46%,whereas myofibre density was significantly augmented(P<0.05)in other groups except for the 1.76%group.For muscle color,L* value in the 1.76%group and b* value in the 1.41%group were significantly lower than those in other groups(P<0.05).The a* values exhibited an increasing trend,and highest value occurred in the 1.41%group(P>0.05).The activities of superoxide dismutase(SOD)and peroxidase(POD),catalase(CAT)and contents of glutathione(GSH),and total antioxidant capacity(T-AOC)were significantly elevated(P<0.05)in the 1.41%cohort in contrast to the other groups,whereas malondialdehyde(MDA)content in the muscle reached the lowest level in the 1.41%group,showing no significant differences(P>0.05).The expression of rapamycin target protein(tor),protein kinase B(akt),S6 protein kinase 1(s6k1),4E-binding protein 1(4ebp1),and forkhead box O1(foxo1)was substan-tially upregulated in muscle in the 1.41%arginine group(P<0.05).Based on WGR,SGR and FCR as evaluation indexes,binomial regression model analysis showed that dietary arginine requirements for Songpu mirror carp in growth mid-stage were 1.41%to 1.58%of feed dry matter.关键词
