【摘要】 本研究旨在探究日粮中添加不同水平的复方中草药制剂对林下绿壳蛋乌鸡产蛋性能、蛋品质、血清生化指标的影响。选取520日龄健康、体质量接近的绿壳蛋乌鸡560羽，随机分成4组，分别为对照组和试验Ⅰ组、Ⅱ组、Ⅲ组。对照组饲喂基础日粮，试验Ⅰ组、Ⅱ组、Ⅲ组分别在基础日粮中添加0.5%、1.0%、1.5%的复方中草药制剂，试验期45 d。结果显示，日粮中添加不同水平的复方中草药制剂对林下绿壳蛋乌鸡的平均蛋重、平均产蛋率、绿壳蛋破损率有显著影响，其中Ⅱ组平均蛋重显著高于对照组（P<0.05），Ⅰ组、Ⅱ组平均产蛋率显著高于对照组（P<0.05），Ⅱ组绿壳蛋破损率显著低于对照组（P<0.05）；日粮中添加不同水平的复方中草药制剂对绿壳蛋蛋黄相对重、蛋白高度、蛋黄水分含量、蛋黄指数及哈氏单位有显著影响，其中Ⅱ组绿壳蛋蛋黄相对重显著高于对照组（P<0.05），Ⅰ组、Ⅱ组、Ⅲ组绿壳蛋蛋白高度显著高于对照组（P<0.05），Ⅱ组、Ⅲ组绿壳蛋水分含量显著低于对照组和Ⅰ组（P<0.05），Ⅱ组绿壳蛋蛋黄指数显著高于对照组、Ⅰ组、Ⅲ组（P<0.05），Ⅱ组绿壳蛋哈氏单位显著高于对照组和Ⅲ组（P<0.05）；日粮中添加不同水平的复方中草药制剂对林下绿壳蛋乌鸡的血清总蛋白（TP）、球蛋白（GLO）、丙氨酸氨基转移酶（ALT）、胆固醇（TC）和甘油三酯（TG）有显著影响，其中Ⅰ组、Ⅱ组血清TP含量显著高于对照组（P<0.05），Ⅰ组、Ⅱ组、Ⅲ组血清GLO含量显著高于对照组（P<0.05），Ⅲ组血清ALT活性显著高于对照组和Ⅰ组（P<0.05），Ⅱ组血清TC和TG含量显著高于对照组（P<0.05）。综上，日粮中添加不同水平的复方中草药制剂能改善绿壳蛋乌鸡的产蛋性能、蛋品质及血清生化指标，且以1.0%添加量的复方中草药制剂效果最佳。更多还原

【Abstract】 This study aims to investigate the effects of adding different proportions of compound Chinese herbal medicines to forest blue-eggshell black-boned chickens on the laying performance, egg quality and serum biochemical indicators.560 healthy and with similar body weight blue-eggshell black-boned chickens aged 520 days were selected and randomly divided into 4 groups, including control group and experimental group(group Ⅰ, group Ⅱ and group Ⅲ).The control group was fed with basal diet, while groups Ⅰ, Ⅱ, and Ⅲ were fed the basal diet supplemented with 0.5%,1.0% and 1.5% compound Chinese herbal medicine additives, respectively, the experimental period was 45 days. The results showed that adding different levels of compound Chinese herbal preparations to the diet had significant effects on the average egg weight, average egg production rate, and blue shell egg damage rate of forest blue-eggshell blackboned chickens. Among them, the average egg weight of group Ⅱ was significantly higher than that of the control group(P<0.05), the average laying rate of groups Ⅰ and Ⅱ were significantly higher than that of the control group(P<0.05),and the damage rate of group Ⅱ was significantly lower than that of the control group. Adding different levels of compound Chinese herbal preparations to the diet had a significant effect on the yolk relative weight, egg white content,yolk moisture content, yolk index, and Haugh unit of blue shell eggs(P<0.05). Among them, the relative weight of yolk in blue shell eggs in group Ⅱ was significantly higher than that of control group(P<0.05). The white content of blue shell eggs in groups Ⅰ, Ⅱ, and Ⅲ were significantly higher than that of control group(P<0.05). The moisture content of blue shell eggs in groups Ⅱ and Ⅲ were significantly lower than that of control group and group Ⅰ(P<0.05). The yolk index of blue shell eggs in group Ⅱ was significantly higher than that of control group and group Ⅰ(P<0.05). The Hasselblad unit of blue shell eggs in Group Ⅱ was significantly higher than that of control group and group Ⅲ(P<0.05).Adding different levels of compound Chinese herbal preparations to the diet had a significant effect on serum total protein(TP), globulin(GLO), alanine aminotransferase(ALT), cholesterol(TC) and triglyceride(TG) of forest blueeggshell black-boned chickens(P<0.05). Among them, the serum TP content of groups Ⅰ and Ⅱ were significantly higher than that of control group(P<0.05). The serum GLO content in groups Ⅰ, Ⅱ and Ⅲ were significantly higher than that of control group(P<0.05). The serum ALT activity in group Ⅲ was significantly higher than that of control group and group Ⅰ. And the serum TC and TG contents in group Ⅱ were significantly higher than of control group(P<0.05). In summary, adding different levels of compound Chinese herbal preparations to the diet can effectively improve the egg production performance, egg quality and serum biochemical indicators of blue-eggshell black-boned chickens, especially using 1.0% compound Chinese herbal preparations has the best effect.更多还原
