【摘要】：试验旨在研究包被肉桂油对肉鸡非特异性免疫功能的影响。选用360只1日龄科宝肉鸡,随机分为6个处理组,每组6个重复,每个重复10只鸡。对照组饲喂玉米-豆粕型基础日粮,正对照组在基础日粮中添加50 mg/kg的黄霉素,试验组分别添加50、100、200和300 mg/kg的包被肉桂油(以肉桂醛计),试验期为42 d。结果显示:与对照组相比,50和200 mg/kg试验组14日龄血液中单核细胞的比例上调(P0.05);试验组21日龄血清中溶菌酶的含量增加且呈线性正相关(R~2=0.824),试验组42日龄血清中溶菌酶的含量增加且呈线性正相关(R~2=0.625);试验组42日龄外周血淋巴细胞的LPS刺激指数上调(P0.001)。与正对照组相比,50 mg/kg试验组14日龄血液中单核细胞的比例上调(P0.05);试验组21日龄血清中溶菌酶的含量增加(P0.05);试验组42日龄外周血淋巴细胞的LPS刺激指数上调(P0.05)。结果表明:日粮中添加包被肉桂油有利于促进肉鸡外周血B淋巴细胞的增殖,增强非特异性免疫功能。
[Abstract]:The purpose of the experiment was to study the effect of coated cinnamon oil on nonspecific immune function of broilers. 360 1-day-old Kebao broilers were randomly divided into 6 treatment groups with 6 replicates in each group. The control group was fed corn-soybean meal basal diet, while the control group was fed with 50 mg/kg of flavomycin in the basal diet. The experimental group was treated with 50,100,200 and 300 mg/kg coated cinnamon oil (measured by cinnamaldehyde for 42 days). The results showed that the proportion of monocytes in 14-day blood was up-regulated in the experimental group of 50 and 200 mg/kg compared with that in the control group, and that in the experimental group was 21 days old. The content of lysozyme in serum increased and showed a linear positive correlation. The content of lysozyme in serum of 42 days old in the trial group increased and showed a linear positive correlation. The LPS stimulation index of peripheral blood lymphocytes of 42 days old in the trial group was up-regulated by P0.001, and that in the experimental group was higher than that in the control group. Compared with the control group, the ratio of monocytes in blood of 14 days old was up-regulated in the test group of 50 mg/kg, the content of lysozyme in serum of the experimental group was increased at 21 days of age, and the LPS stimulation index of peripheral blood lymphocytes of 42 days old in the test group was increased. The results showed that:. The addition of coated cinnamon oil in grain could promote the proliferation of B lymphocytes in peripheral blood of broilers. Enhance nonspecific immune function.
