摘要: 为探讨日粮中添加金银花提取物对肉鸡生产性能、屠宰性能、肉品质和抗氧化性能的影响,将240只1日龄Ross 308肉鸡随机分成4组,每组6个重复,每个重复10只鸡,对照组饲喂基础日粮,另外3组在基础日粮中分别添加200、400、600 mg/kg金银花提取物。试验期42 d。结果表明,与对照组相比,日粮添加400 mg/kg 金银花提取物组肉鸡的平均日增质量,以及胸肌的肉色红度值、总抗氧化能力(T-AOC)和谷胱甘肽过氧化物酶(GSH-Px)活性分别显著提高9.47%、18.21%、23.13%和25.84%;胸肌中GSH-Px和核因子E2相关因子2(Nrf2)基因表达水平显著提高;料肉比、胸肌的滴水损失和丙二醛(MDA)含量分别显著降低5.98%、17.22%和17.09%。日粮添加600 mg/kg金银花提取物组肉鸡的平均日增质量,以及胸肌的肉色红度值、T-AOC 和GSH-Px活性分别显著提高11.08%、18.99%、27.21% 和35.88%;胸肌中超氧化物歧化酶(SOD)、GSH-PxNrf2基因表达水平显著提高;料肉比、胸肌的滴水损失、蒸煮损失和MDA含量分别显著降低7.07%、19.33%、15.33%和22.70%。综上,肉鸡日粮中添加金银花提取物通过调控胸肌中Nrf2基因表达,提高胸肌中GSH-Px 基因表达量及其相应抗氧化物酶活性,进而提高胸肌的抗氧化性能,改善肉鸡胸肌肉品质。

Abstract: In order to investigate the effects of Lonicera japonica Thunb.extract on production performance,slaughter characters,meat quality and antioxidant capacity of broilers,240 1‑day‑old Ross 308 broilers were randomly divided into four groups with six replicates in each group and 10 broilers per replicate. The control group was fed with basic diet,and the other three groups were fed with basic diet added with 200,400,600 mg/kg Lonicera japonica Thunb.extract.The experiment lasted for 42 d.The results showed that compared with the control group,the average daily gain,and meat color redness,total antioxidant capacity(T‑AOC)and glutathione peroxidase(GSH‑Px)activity in the breast muscle of broilers fed with 400 mg/kg Lonicera japonica Thunb.extract were significantly increased by 9.47%,18.21%,23.13% and 25.84%,respectively;the expression levels of GSH‑Px and nuclear factor E2 related factor 2(Nrf2) genes in the breast muscle were significantly increased;the feed conversion ratio,and dripping loss and malondialdehyde(MDA)content of breast muscle were significantly decreased by 5.98%,17.22% and 17.09%,respectively.The average daily gain,and meat color redness,T‑AOC and GSH‑Px activity in the breast muscle of broilers fed with diet supplemented with 600 mg/kg Lonicera japonica Thunb.extract were significantly increased by 11.08%,18.99%,27.21% and 35.88%,respectively;the expression levels of superoxide dismutase(SOD),GSH‑Px and Nrf2 genes in the breast muscle were significantly increased;the feed conversion ratio,and dripping loss,cooking loss,and MDA content of breast muscle were significantly decreased by 7.07%,19.33%,15.33% and 22.70%,respectively.In conclusion,adding Lonicera japonica Thunb.extract to the diet could increase the expression of GSH‑Px gene and its corresponding antioxidant enzyme activity by regulating Nrf2 gene expression in the breast muscle,so as to improve the antioxidant performance and meat quality of broiler breast muscle.
