摘　　要：试验旨在研究饲粮中添加复合植物精油对黄麻鸡生长性能、免疫力及肉品质的影响,为黄麻鸡的绿色健康养殖提供参考。试验选择21日龄的黄麻鸡600只,随机分成4组,每组5个重复,每个重复30只黄麻鸡。对照组、精油1组、精油2组、精油3组黄麻鸡饲粮中分别添加0、200、400、800 mg/kg的复合植物精油。试验期8 w。结果显示:与对照组相比,精油2组黄麻鸡的料重比显著降低(P<0.05),血清免疫球蛋白M(IgM)、白细胞介素-10(IL-10)水平显著升高(P<0.05),白细胞介素-6(IL-6)水平显著降低(P<0.05);所有复合植物精油组黄麻鸡血清肿瘤坏死因子-α(TNF-α)水平显著降低(P<0.05)。与对照组相比,精油2组和精油3组黄麻鸡血液淋巴细胞数量显著提高(P<0.05),腹脂率显著降低(P<0.05);精油2组和精油3组黄麻鸡胸肌pH24 h值、肉色a*值显著提高(P<0.05),精油2组胸肌剪切力和滴水损失均显著降低(P<0.05)。研究表明,复合植物精油能够提高黄麻鸡的饲料利用率、免疫力,改善肉品质,降低腹脂率,复合植物精油适宜添加水平为400 mg/kg。The experiment aimed to investigate the effects of adding plant essential oil compounds to the feed on the growth performance,immunity,and meat quality of Huangma chickens,providing a reference for green and healthy breeding of Huangma chickens.The experiment selected 600 Huangma chickens at 21 days of age,randomly divided into four groups,with five replicates per group,each replicate containing 30 chickens.The control group,essential oil group 1,essential oil group 2,and essential oil group 3 were fed with 0,200,400,800 mg/kg of plant essential oil compounds,respectively.The experimental period was eight weeks.The results showed that compared with the control group,the feed to gain ratio of the essential oil group 2 chickens was significantly reduced(P<0.05),the levels of serum immunoglobulin M(IgM)and interleukin-10(IL-10)were significantly increased(P<0.05),and the level of interleukin-6(IL-6)was significantly decreased(P<0.05).The levels of tumor necrosis factor-α(TNF-α)in all plant essential oil compounds groups were significantly reduced(P<0.05).Compared with the control group,the lymphocyte content in the blood of the essential oil group 2 and group 3 chickens was significantly increased(P<0.05),and the abdominal fat rate was significantly reduced(P<0.05).The pH24 h value and the a*value of the breast muscle in the essential oil group 2 and group 3 chickens were significantly improved(P<0.05),and the shear force and water loss of the breast muscle in the essential oil group 2 chickens were significantly reduced(P<0.05).The study suggests that the plant essential oil compounds can enhance the feed utilization rate and immunity,improve meat quality,and reduce the abdominal fat rate of Huangma chickens,and the appropriate addition level of the plant essential oil compounds is 400 mg/kg.
