摘要: 本研究旨在探究3种不同添加剂对91~115日龄清远麻鸡生长性能、抗氧化能力、肌肉品质、肌肉感官评定及风味物质含量的影响。试验采用单因素随机分组设计,选用1 200只91日龄清远麻鸡母鸡分为4个组,每组10个重复,每个重复30只鸡,饲养周期25 d。对照组饲喂基础饲粮(CON),3个处理组分别在基础饲粮中添加纳米铜复配预混剂(NC)、灵芝孢子粉复配预混剂(GLS)和大豆异黄酮预混剂(SI)。试验结束后,采集试验鸡血浆、空肠黏膜及胸肌样品,测定血液与空肠的抗氧化能力、胸肌肉质性状及风味物质含量。结果显示,与对照组相比,①3种添加剂对91~115日龄清远麻鸡的生长性能及胴体性状均无显著影响(P>0.05);②3种添加剂组试验鸡胸肌亮度(L*)值显著降低(P<0.05)、pH显著提高(P<0.05),GLS组胸肌滴水损失显著降低(P<0.05);③使用蒸的方式烹饪时,SI组肌肉的色泽与外形评分显著提高(P<0.05),GLS组肌肉在蒸和煮的烹饪方式下多汁度均显著提高(P<0.05);④NC与SI组试验鸡肌肉中肌苷酸与谷氨酸含量显著提高(P<0.05),SI组肌内脂肪含量也显著提高(P<0.05);⑤NC组试验鸡血浆谷胱甘肽过氧化氢酶(GSH-Px)活性及SI组试验鸡空肠GSH-Px活性均显著提高(P<0.05),GLS组试验鸡空肠丙二醛(MDA)含量显著降低(P<0.05)。综上,在本试验条件下,3种添加剂对91~115日龄清远麻鸡生长性能与胴体品质没有显著影响,但可提高肉鸡抗氧化能力,改善其肉品质,提高肌肉感官特性,其中NC与SI可增加肉中风味物质含量,效果更优。

Abstract: This experiment was conducted to investigate the effects of three additives on growth performance, antioxidant capacity, meat quality and content of flavoring substances in muscle of Qingyuan Partridge chickens aged 91 to 115 days.A total of 1 200 91-day old chickens were randomly assigned to 4 groups with 10 replicates of 30 birds per replicate.The control group was fed with basal diet(CON), and birds in treatment groups were supplemented with nano copper compound premix(NC), spores of Ganoderma lucidum compound premix(GLS) and soybean isoflavone premix(SI) for 25 days, respectively.At the end of the experiment, samples of plasma, jejunal mucosa and pectoral muscle were collected to determine the antioxidant capacity of blood and jejunum, the meat quality and the content of flavor substances.The results showed that, compared with the control group:①The growth performance and the carcass traits of Qingyuan Partridge chickens were not affected by the three compound additives (P>0.05).②All these three additives significantly reduced L* value (P<0.05), increased pH (P<0.05) of breast muscle, and GLS reduced the drip loss of breast muscle (P<0.05).③The scores of color and appearance in SI group were increased when steamed (P<0.05), and the scores of juiciness in GLS group were increased when steamed or boiled (P<0.05).④NC and SI increased the contents of inosinic acid and glutamic acid in muscle (P<0.05), and SI increased the content of intramuscular fat (P<0.05).⑤NC increased the activity of glutathione catalase (GSH-Px) in plasma (P<0.05), and SI increased that in jejunum (P<0.05);GLS decreased the MDA content in jejunum (P<0.05).Based on this experiment, the NC, GLS and SI did not affect the growth performance and carcass traits of Qingyuan Partridge chickens at 91 to 115 d.All these additives enhanced the antioxidant capacity of chickens, improved the meat quality, and increased scores of sensory evaluation.NC and SI also affected the contents of flavor substances in meat, had the better effects.

Key words: Qingyuan Partridge chicken; antioxidant capacity; meat quality
