为研究合成大豆异黄酮（ISF）对肉仔鸡生长性能、肉品质和抗氧化能力的影响，将1,500只42日龄肉仔鸡随机分为5个处理，每个处理6个重复（50只/重复）。在3周的时间内，分别向鸡喂食添加0、10、20、40或80 mg ISF/kg的饲料，自由采食。结果表明，添加10和20 mg/kg的ISF分别使增重提高13.6和16.2%（P < 0.01），采食量提高7.37%（P < 0.05）和11.2%（P < 0.01）。添加10 mg/kg ISF使料重比降低5.5%（P < 0.05）。日粮中添加40 mg/kg的ISF可使肉的持水力提高17.24%（P < 0.1），但添加20或40 mg/kg的ISF可显著提高肉的pH值（P < 0.01），但添加40或80 mg/kg的ISF可使肉色变淡（P < 0.05）。20、40、80 mg/kg添加ISF可极显著降低胸肌丙二醛生成量（P <0.01），20 mg/kg添加ISF可极显著降低血浆丙二醛生成量（P < 0.01）。添加40和80 mg/kg的ISF显著提高了雏鸡血浆总抗氧化能力（P < 0.01），并使血浆总超氧化物歧化酶（SOD）活性略有升高（P < 0.1）。80 mg/kg剂量的lSF对血浆中过氧化氢酶活性有轻微的提高作用（P < 0.06）。40和80 mg/kg的ISF处理使胸肌超氧化物歧化酶（SOD）活性分别提高25.36%（P < 0.05）和63.93%（P < 0.01）。添加40 mg ISF可显著提高过氧化氢酶活性，提高幅度为70.61%（P < 0.05）。此外，10、20或40 mg/kg剂量的ISF降低乳酸产生（P < 0.05）。本研究结果表明，饲粮ISF可通过降低肉仔鸡体内脂质过氧化反应，改善抗氧化状态，从而改善肉仔鸡的生长性能和肉品质。
To investigate the effects of a synthetic soybean isoflavone (ISF) on growth performance, meat quality, and antioxidation in male broilers, 1,500 birds that were 42 d old were allotted to 5 treatments with 6 replicates per treatment (50 birds per replicate). Birds were fed diets supplemented with 0, 10, 20, 40, or 80 mg of ISF/kg, respectively, for a period of 3 wk ad libitum. The results showed that dietary supplementations with 10 or 20 mg of ISF/kg increased weight gain by 13.6 and 16.2% (P < 0.01) and elevated feed intake by 7.37% (P < 0.05) and 11.2% (P < 0.01), respectively. Addition of 10 mg of ISF/kg decreased feed:gain by 5.5% (P < 0.05). Supplementation with 40 mg of ISF/kg in the diet slightly increased water-holding capacity by 17.24% (P < 0.1), and the addition of 20 or 40 mg/kg of ISF significantly increased the pH value of meat (P < 0.01), although adding 40 or 80 mg of ISF/kg increased the lightness of meat color (P < 0.05). Malondialdehyde production was slightly reduced in plasma of 20 mg of ISF/kg supplemented chickens (P < 0.1) and significantly decreased in breast muscles of 20,40, or 80 mg of ISF/kg supplemented chickens (P < 0.01). The addition of 40 or 80 mg of ISF/kg significantly increased total antioxidant capability (P < 0.01) and slightly elevated total superoxide dismutase activity (P < 0.1) in plasma of chickens. The dose of 80 mg of lSF/kg slightly improved catalase activity in plasma (P < 0.06). In breast muscle, treatment of birds with 40 or 80 mg of ISF/kg caused an increase of total superoxide dismutase activity by 25.36% (P < 0.05) or 63.93% (P < 0.01). Catalase activity significantly increased by 70.61% by the supplemental ISF at the 40-mg level (P < 0.05). Also, 10, 20, or 40 mg doses of ISF/kg decreased lactic acid production (P < 0.05). The results of this study indicate that dietary ISF could improve growth performance and meat quality by decreasing lipid peroxidation and improving antioxidative status in male broilers.
