摘要: 本试验选择28日龄岭南黄慢速型黄羽肉鸡1200只,随机分成3组,每组10个重复,公母各半,每个重复40只鸡。对照组饲喂基础日粮,试验组分别饲喂基础日粮添加0.1%和0.2%荷叶提取物,饲养至120日龄出栏,研究日粮添加荷叶提取物对黄羽肉鸡肉品质及抗氧化活性的影响。结果显示,在日粮中添加0.1%荷叶提取物能够显著提高黄羽肉鸡公鸡肌肉pH45 minP<0.05)及母鸡肉色b* 值(P<0.05);显著提高公鸡肌肉总抗氧化能力(P<0.05)和谷胱甘肽过氧化物酶(P<0.01),降低丙二醛含量(P<0.05);对母鸡抗氧化活性也表现出与公鸡一致的作用趋势,提高胸肌总抗氧化能力(P<0.1),显著提高GSH-Px活性(P<0.05),降低MDA含量(P<0.1)。与对照组相比,日粮添加0.2%荷叶提取物也可以显著提高母鸡肉色b* 值(P<0.05),但对本试验中其他肉品质指标及抗氧化指标均无显著性影响。由此可见,日粮中添加0.1%荷叶提取物可以增强黄羽肉鸡的抗氧化能力,从而改善肌肉品质。

Abstract: To determine the effect of dietary supplementation of lotus leaves extract(LLE) on antioxidant ability and meat quality of yellow broilers, 1200 birds were randomly divided into 3 groups having 10 replicates(half male and half female)of 40 chicks each. The control group was fed a basal diet, the other two treatment groups were fed the basal diet with added 0.1% and 0.2% LLE respectively until 120 days of age. Dietary supplemented with 0.1% LLE increased pH45 min value of muscle in male(P<0.05) and breast meat colour b* value in female(P<0.05). Supplementation with 0.1% LLE also improved total antioxidant capacity(T-AOC)(P<0.05) and glutathioneperoxide(GSH-Px) activity(P<0.01), decreased malondiadehyde(MDA) content in musle of male significantly.The effect of LLE on antioxidant ability of female had a same trend with female, T-AOC was increased(P<0.1), GSH-Px activity was significantly improved(P<0.05), and MDA content was decresed(P<0.1). Compared with the control, 0.2% LLE supplementation also increased breast meat colour b* value in female(P<0.05), but other index of meat quality and antioxidant ability did not differ. The results indicated that the LLE supplementation improved antioxidant ability of yellow broilers and had a benificial effect on meat quality.
