摘要
本研究旨在研究黄芩黄酮对黄羽肉鸡生长性能、肉品质和抗氧化能力的影响。选取320只1日龄体重相近的雄性快大型黄羽肉鸡,随机分为4组,每组8个重复,每个重复10只鸡。对照组饲喂基础饲粮,试验组分别饲喂在基础饲粮中添加150(SF150组)、300(SF300组)和450 mg/kg(SF400组)黄芩黄酮的试验饲料。试验期50 d。结果显示:与对照组相比,饲粮中添加300和450 mg/kg的黄芩黄酮显著降低了料重比(P<0.05);各试验组宰后24 h胸肌pH显著增加(P<0.05),SF450组宰后24 h胸肌的红度(a*)值显著提高(P<0.05);SF450组血浆中丙二醛(MDA)的含量与SF150组和SF300组血浆中乳酸脱氢酶(LDH)的活性显著降低(P<0.05);SF300和SF450组胸肌中总抗氧化能力(T-AOC)显著上升(P<0.05),SF300组胸肌中总超氧化物歧化酶(T-SOD)的活性也显著上升(P<0.05);SF300组肝脏中核因子E2相关因子2(Nrf2)和血红素加氧酶-1(HO-1)的mRNA相对表达量显著增加(P<0.05),SF300和SF450组肝脏中谷胱甘肽过氧化物酶(GSH-Px)的mRNA相对表达量显著增加(P<0.05)。综上可知,饲粮中添加300 mg/kg黄芩黄酮可显著提升黄羽肉鸡的饲料利用率,改善抗氧化能力,从而改善肉品质,这些作用可能与Nrf2/HO-1信号通路的激活有关。
This study was conducted to investigate the effects of dietary supplementation with Scutellaria flavonoids(SF)on growth performance,meat quality and antioxidant capacity of broilers yellow-feathered broilers.A total of 320 one-day-old yellow-feathered male broilers(fast-growing)with similar body weight were randomly allocated into four groups,with 8 replicates per group and 10 birds per replicate.The control group was fed a basal diet,while the experimental groups were fed the basal diet supplemented with 150(SF150 group),300(SF300 group),and 450 mg/kg(SF450 group)of SF,respectively.The trial lasted for 50 days.The results showed as follows:compared with the control group,dietary supplementation with 300 and 450 mg/kg of SF significantly reduced the feed-to-gain ratio(P<0.05);the pH of the breast muscle at 24 hours postmortem was significantly increased in all experimental groups(P<0.05),and the redness(a*)value was significantly increased in the SF450 group(P<0.05);the content of plasma malondialdehyde(MDA)in the SF450 group and the activity of plasma lactate dehydrogenase(LDH)in the SF150 and SF300 groups were significantly decreased(P<0.05);the breast muscle total antioxidant capacity(T-AOC)in the SF300 and SF450 groups was significantly increased(P<0.05),and the activity of breast muscle total superoxide dismutase(T-SOD)was also significantly increased in the SF300 group(P<0.05);the mRNA relative expression levels of liver nuclear factor erythroid 2 related factor 2(Nrf2)and heme oxygenase-1(HO-1)were significantly increased in the SF300 group(P<0.05),while the mRNA relative expression level of liver glutathione peroxidase(GSH-Px)was significantly increased in the SF300 and SF450 groups(P<0.05).In conclusion,dietary supplementation with 300 mg/kg SF can significantly enhance the feed utilization efficiency and improve the antioxidant capacity of yellow-feathered broilers,thereby ameliorating meat quality,and these effects may be attributed to the activation of the Nrf2/HO-1 signaling pathway.
