摘要:

本试验旨在研究日粮中添加不同水平超氧化物歧化酶模拟物(superoxdie dismutase mimics,SODm)对肉仔鸡生长性能、肉品质及超氧化物歧化酶(SOD)活性的影响。采用单因子试验设计,选取1日龄爱拔益加(AA)肉仔鸡公雏432只,随机分成6组,每组6个重复,每个重复12只。对照组饲喂基础日粮,试验组在基础日粮中分别添加0.10%、0.15%、0.20%、0.25%、0.30% SODm,试验期42 d。结果表明:①日粮添加SODm对肉仔鸡平均日采食量(ADFI)、平均日增重(ADG)和料重比(F/G)均无显著影响(P>0.05)。②添加0.20%、0.25%和0.30% SODm组胸肌亮度(L*)值显著低于对照组(P<0.05);除0.10% SODm组外,SODm各组胸肌剪切力均显著低于对照组,滴水损失显著高于对照组(P<0.05)。SODm各组腿肌L*值均显著低于对照组(P<0.05);0.10%和0.15% SODm组腿肌剪切力显著低于对照组(P<0.05)。③21日龄时,与对照组相比,0.30% SODm组血清SOD活性显著降低(P<0.05),其他SODm组血清SOD活性均有提高,但差异不显著(P>0.05);42日龄时,添加SODm各组血清SOD活性均显著高于对照组(P<0.05)。④21日龄时,SODm各组肝脏SOD活性均显著高于对照组(P<0.05);添加SODm对胸肌和心脏SOD活性无显著影响(P>0.05)。42日龄时,添加0.15%和0.25% SODm组肝脏和心脏SOD活性显著高于对照组(P<0.05);0.25%和0.30% SODm组胸肌和腿肌SOD活性显著高于对照组(P<0.05)。综上,本试验条件下,在日粮中添加SODm对肉仔鸡生长性能无显著影响;添加0.15%~0.25% SODm可提高肉仔鸡体内SOD活性,降低肌肉亮度和剪切力,改善肌肉嫩度。

Abstract:

The aim of this study was to evaluate the effects of dietary superoxdie dismutase mimics (SODm) on growth performance,meat quality and activity of superoxdie dismutase(SOD) in broilers.Four hundred and thirty two 1-day-old healthy male AA broilers were randomly assigned to 6 groups with 6 replicates per group and 12 birds per replicate.The control group was fed corn-soybean meal basal diet,and 5 experiment diets were added 0.10%,0.15%,0.20%,0.25% and 0.30% SODm,respectively.The test lasted for 42 d.The results showed as follows:①The ADFI,ADG and F/G were not significantly affected by the different levels of SODm (P>0.05).②Compared with the control group,the L* value of breast muscle in 0.20%,0.25% and 0.25% SODm groups were significantly decreased (P<0.05).Except for 0.10% SODm group,the shear force of breast muscle was significantly lower than that of control group (P<0.05),while the drip loss was significantly increased than that of control group (P<0.05).With SODm supplementation,the L* value of leg muscle were found to decrease significantly compared with control group (P<0.05);The shear force of leg muscle in 0.10% and 0.15% SODm groups was significantly lower than that in control group (P<0.05).③At 21 days of age,compared with control group,the activity of SOD in serum was higher (P>0.05),but except for 0.30% SODm group which was significantly decreased (P<0.05).The activity of SOD in serum at 42 days of age was discovered significantly increased with SODm supplementation (P<0.05).④Compared with control group,the activity of SOD in liver at 21 days of age was significantly increased with dietary SODm supplementation (P<0.05).SODm did not significantly affect the SOD activity of breast muscle and heart at 21 days of age (P>0.05).The activity of SOD in liver and heart in 0.15% and 0.25% SODm groups at 42 days of age were significantly higher than that of control group (P<0.05),while the supplement of 0.25% and 0.30% SODm had an outstanding effect on the activity of SOD of breast and thigh muscle (P<0.05).It was concluded that the supplement of SODm had no negative effects on the growth performance,and 0.15% to 0.25% dietary SODm could improve SOD activity and the tenderness,L* value and shear value of muscle.
