| 摘 要： | 目的:研究中药大黄对蛋鸡产蛋性能及蛋品质的影响。方法:选择体重及生产性能相近的430日龄健康罗曼蛋鸡48只,随机分为对照组和试验组2组,每组设4个重复,每个重复6只鸡。其中A组为对照组,饲喂基础日粮,B组为试验组,在基础日粮中添加1%的中药大黄。预试期1周,正试期为6周。结果:试验结果表明2组间的产蛋率、蛋壳颜色、平均蛋重、蛋形指数、蛋黄指数、软破壳蛋率、料蛋比、采食量、哈夫单位差异不显著(P0.05)。与A组相比,B组蛋的比重显著增加(P0.05),蛋壳厚度虽有所增加,但差异不显著(P0.05)。蛋黄颜色改善极显著(P0.01),灰分含量极显著下降(P0.01),脂肪含量显著降低(P0.05),蛋白质含量升高,但差异不显著(P0.05)。结论:在饲料中添加1%的中药大黄对蛋鸡产蛋性能没有显著的影响,但能显著的改善鸡蛋的物理特性。

| Abstract: | Objective ： To investigate the effects of rhubarb on laying performance of the hens and egg quality. Methods ： 430 - day - old 48 healthy Roman layer hens which weight and laying performance were similar were selected and randomly di- vided into two groups, each group with four replicates, every replicate with six laying hens. Group A was the control group which hens fed with the basal diet, and Group B was the treatment group which hens fed with the basal diet added 1% rhu- barb. Pretest period was a week, and the test period was six weeks. Results：The experiment results showed that two groups of egg production, egg shell color, the average egg weight, egg shape index, the index of egg yolk, the rate of soft and bro- ken egg shell, feed conversion ratio,intake and HF unit differences were not significant （ P 〉 0.05 ）. Compared with group A, the egg density of group B was increased significantly （P 〈 0.05）, however, egg shell thickness was increased, but the difference was not significant （ P 〉0.05 ）. Egg yolk color was improved significantly （ P 〈0.01 ） ,and the content of ash was also decreased significantly （ P 〈 0.01 ）, and the content of fat was decreased significantly （ P 〈 0.05）, then the content of protein was increased, but the difference was not significant （ P 〉 0.05 ）. Conclusion ： Adding 1% rhubarb in the layer diet performance is not significant impact, but it can significant improve the physical characteristics of the egg. |
