摘　　要：为研究柠檬酵素对其生长性能以及免疫功能的影响,将100只1日龄雏鸡随机分为5组,分别以1.0%、0.5%、0.25%柠檬酵素拌玉米粉进行饲喂,并与市售黄芪多糖以及空白组进行比较,于14日龄、21日龄、28日龄取样。结果表明:15~28日龄,添加1%柠檬酵素显著提高了雏鸡平均日增重(P<0.05),一定程度上降低料重比(P>0.05);21日龄、28日龄时,添加1%柠檬酵素一定程度上提高了雏鸡脾脏指数和法氏囊指数(P>0.05),对胸腺指数影响不显著;添加柠檬酵素具有提高雏鸡血液中淋巴细胞数、淋巴细胞比率以及血小板总数的趋势(P>0.05)。研究表明:柠檬酵素具有一定促进雏鸡生长性能和免疫力的作用,且以1%拌料效果较好。The effects of lemon enzyme on the growth performance and immune function on chicken were studied. One hundred one-day-age chickens were randomly divided into 5 groups, fed with 1.0%, 0.5%, 0.25% lemon enzyme mixed with corn flour. The positive and negative groups were fed with commercially available Astragalus polysaccharides and saline, respectively. The samples were collected at 14, 21, 28 days of age. The results showed that 1.0% lemon enzyme could increase the weight of chickens （P〈0.05）and partly reduce material weight ratio （P〉0.05）at the age of 15 to 28 days. And 1% lemon enzyme increased the purtenance index of spleen and bursa in certain degree at the age of 21, 28 days （P〉0.05）, but there was no signifant effect on thymus index. Finally, the lemon enzymes demonstrated a trend of improving the lymphocyte count, the percentage of lymphocytes and the total number of platelets （P〉0.05）. Thus, it showed that lemon enzyme had certain growth-promotion performance and immunity strengthen function, and mined with 1% lemon enzyme was better.
