中草药添加剂对蛋雏鸡增重及血液生化指标的影响

Effect of Chinese Herb Feed Additives on Weight Gain and Blood Biochemical Index of Laying Chicks

为了解不同中草药复方添加剂对蛋雏鸡增重及血液生化指标的影响，选取1日龄健康雄性海兰蛋鸡雏80只，随机分为4组（试验I～Ⅲ组，对照组），每组20只。试验I～Ⅲ组分别饲喂具有增强机体免疫力、健脾消食及抗菌抗病毒作用的中草药复方饲料添加剂，测定并比较各组蛋雏鸡在试验期间的增重及血液生化指标。结果表明，试验I组蛋雏鸡的试验期增重及血清胆固醇含量显著高于对照组（P〈0．05），其余指标差异均不显著（19〉0．05）；试验Ⅱ组蛋雏鸡的血液总蛋白、血清钙、血清无机磷均显著高于对照组（P〈0．05），试验期增重及血清胆固醇含量极显著高于对照组（P〈0．01）：试验Ⅲ组蛋雏鸡的试验期增重及各项血液生化指标与对照组相比，差异均不显著（P〉0．05）。健脾消食类的中草药复方饲料添加剂能够显著促进蛋雏鸡生长，有效改善蛋雏鸡血液生化指标，有利于雏鸡健康、快速的生长。

In order to investigate the impact of Chinese herb feed additives on weight gain and blood biochemical index of laying chicks, a total of 80 health male Hyline laying chicks were selected and randomly divided into four groups （experiment group I - Ⅲ, control group）, with 20 chicks for each group. Experiment group I - Ⅲ fed with the Chinese herb feed additives with efficacy of enhancing immunity, invigorating the function of the spleen and promoting digestion, and antivirus and antibacterial, respectively. The weight gain and blood biochemical index of the experiment groups and control group were determined. The results showed that the weight gain and serum cholesterol content of experiment group I were significantly higher than those of control group （P〈0.05）, no significant differences of the other index were observed between them （P〉0.05）; the blood total protein, serum calcium and serum inorganic phosphorus of experiment group Ⅱ were significantly higher than those of control group （P〈0.05）, and the weight gain and serum cholesterol content of experiment group Ⅱ were extremely significantly higher than those of control group （P〈0.01）; no significant differences of weight gain and all of the tested blood biochemical index were found between experiment group I and control group （P〉0.05）. It was indicated that the Chinese herb feed additives with efficacy of invigorating the function of the spleen and promoting digestion could significantly promote the growth and improve the blood biochemical index of laying chicks, which was favorable for the healthy and rapid growth of laving chicks.
