| 摘 要： | 研究了万寿菊叶黄素(Marigold Lutein,MAR)和维生素C(VC)对高温环境下罗曼粉壳蛋鸡生产性能和蛋品质的影响规律。将216只180日龄身体健康、体重相似的罗曼粉蛋鸡作为试验动物,随机分为6个组,每组设3个重复,每个重复12只鸡。试验1组为高温对照组,饲喂基础日粮,试验2组饲喂基础日粮+200mg/kg VC,试验3、4、5、6组在试验2组的基础上,分别添加60mg/kg、120mg/kg、180mg/kg、240mg/kg万寿菊叶黄素(分别组成复合剂Ⅰ、Ⅱ、Ⅲ、Ⅳ)。试验期56d,其中预试期14d,正式期42d。研究结果表明,在长期高温环境中,日粮中添加120mg/kg MAR+200mg/kg VC,可有效提高蛋鸡生产性能,其中采食量、产蛋率、平均蛋重分别较对照组提高26.79%(P<0.01)、13.87%(P<0.05)和4.1%(P<0.01),破壳率降低53.49%(P<0.01),死淘率为0;同时可有效改善蛋品质,与对照组比较,蛋壳厚度、哈氏单位、蛋黄相对重有提高的趋势(P>0.05);蛋黄RCF值提高2.12(P<0.01)、蛋黄红度(a*)提高90.37%(P<0.01)、蛋黄黄度(b*)提高11.36%(P<0.01)。

| Abstract: | The objective of this study was to reveal influence rules of marigold lutein and vitamin C on production performance and egg quality of Lohmann laying hens in high temperature. Two hundred and sixteen 180 day old Roman laying hens with similar weight and healthy condition were randomly divided into 6 groups with 4 replicates each and 12 hens in each replicate. The group 1 was a control group at a high temperature and fed the corn soybean meal basal diet. The treatment 2 was fed basal diet with 200 mg/kg VC, and treatment 3、4、5、6 were added 60 mg/kg、120 mg/kg、180 mg/kg、240 mg/kg marigold lutein in the basal diet compared with that of treatment 2. This experiment lasted for 56 days, including 14 day adaptation. The results showed that supplementation of 120 mg/kg MAR＋200 mg/kg VC significantly increased production performance at high temperature. Compared with the control group, feed intake and laying rate increasedby 26.79%（P<0.01）and 13.87%（P<0.05）. Furthermore, average egg weight increasedby 4.1%（P<0.01）, egg breaking rate decreasedby 53.49%（P<0.01）, and mortality decreased to 0.At the mean time, egg quality was efficiently improved. There was an increasing trend in shell thickness, Haugh unit and yolk relative weight（P＞0.05）, values of RCF increasedby 2.12（P＜0.01）, moreover, red value and yellow value raisedby 90.37%（P＜0.01）and 11.36%（P＜0.01）respectively. |
