摘  要：
试验以百里香酚、丁香酚、香芹酚复合而成的植物精油作为研究对象,选用1日龄AA肉仔鸡作为试验动物,按随机原则分为对照组和试验组Ⅰ、Ⅱ、Ⅲ,精油添加量分别为0、80、160、240 mg/kg饲料。通过对其生长性能、免疫器官指数、屠宰性能的测定,得出结论:1由百里香酚、香芹酚、丁香酚组成的植物精油可以提高肉仔鸡的采食量、日增重,降低料重比,且随着精油剂量增加呈现先增加后降低的趋势;2在屠宰性能方面,可以提高胸肌和腿肌产量,与对照组相比,试验组Ⅱ胸肌率差异显著(P<0.05),腿肌率试验组Ⅰ、Ⅱ达极显著水平(P<0.01);3试验所用精油可以极显著提高肉仔鸡42日龄肉仔鸡脾脏和法氏囊指数(试验组Ⅲ除外)(P<0.01),但对胸腺指数无影响;4各组血清免疫球蛋白Ig G含量均极显著提高(P<0.01),说明植物精油可以提高肉仔鸡的免疫机能;5综合试验结果,植物精油的适宜添加量为80 mg/kg饲料,可以为实际应用提供依据。

摘  要：
The purpose of this study is to validate the effects of essential oil on the growth perfor-mance, carcass quality, immune function of broilers. At the same time, the appropriate supplement lev-els of essential oil was also analyzed. Healthy AA broilers of one day old, with similar initial bodyweight, evenly divided between male and female, were randomly allotted to four treatments which in-cluded a control group and three experimental groups. Control group was fed basic diet, and experimen-tal group Ⅰ, experimental group Ⅱ, and experi-mental group Ⅲ were fed basal diet + 80 mg/kgessential oil, basal diet+160 mg/kg essential oil,and basal diet + 240 mg/kg essential oil respec-tively. The experiment lasted 42 d. The resultswere as followed:(1) Comparing with the control group, average body weight of broilers in group Ⅰ,group Ⅱ and group Ⅲ was increased significantly(P<0.05). That indicated essential oil could promotegrowth of broilers.(2) Compared with control group, chest muscle rate and leg muscle rate in group Ⅰ,group Ⅱ and group Ⅲ was improved.(3) The thymus index and bursa index of each experimentalgroup was higher than the control group,and get the significant level at 42 days old, but the spleen in-dex of each experimental group were not significant(P>0.05). That indicated essential oil could pro-mote immune function of broilers.(4) The lysozyme and Ig G of each experimental group was higherthan the control group,and got the significantce(P<0.05).(5) Comprehensive experimental resultsshowed, essential oil appropriate adding amount of broiler feed was 80 mg/kg complete feed. It couldbe as the guide for practice.
