| 摘 要： | 研究旨在观察比较樟科（CFPE）、丝兰（YE）、一串红（SS）和桂花（OFL）植物提取物对肉鸡氨散发量、生产性能、免疫机能以及血液生化指标的影响。将500只0日龄AA肉鸡随机分为5组：即肉桂、丝兰、一串红和桂花提取物200mg/kg添加试验组,及基础日粮对照组。每个试验组4个重复,每个重复25只。结果表明,与对照组相比,各试验组均显著降低氨气的散发（P〈0.05）,提高日增重,降低料肉比（P〈0.05）,显著改善肉鸡血液生化指标（P〈0.05）：增高血清总蛋白的含量,降低血清尿素氮、血清尿酸含量和黄嘌呤氧化酶的活性;同时,桂花组显著提高血液中CD4^＋的含量和CD4^＋/CD8^＋,降低CD8^＋的含量（P〈0.05）。结果提示,日粮中添加肉桂、丝兰、一串红、桂花提取物均能显著改善肉鸡生长性能,增强机体免疫机能,且在降低鸡舍中的氨气浓度,改善饲养环境方面,一串红、桂花植物提取物完全可以达到甚至超过樟科、丝兰植物提取物的作用效果。

| Abstract: | The study was conducted to compare the effects of cinnamon,yucca schidigera,SS and OFL extracts on emission of NH3,growth performance,immunity and blood biochemical indicators in broiler chicks.A total of 500 zero-day-old AA broiler chicks were randomly allocated to five experimental groups with four replicates of twenty-five chicks each.CFPE group received basal diet with CFPE 200 mg/kg,YE group with YE 200 mg/kg,SS group received basal diet with SS 200 mg/kg,OFL group with OFL 200 mg/kg,and the control received basal diet.The results showed that,compared with the control group,the test groups could significantly lessen the emission of NH3（P〈0.05）,improve average daily mass gain,and reduce average feed-weight ratio（P〈0.05）,the concentration of TP in serum was significantly increased,and the concentration of SUA,SUN and the activity of xanthine oxidase in serum were significantly decreased in all the test groups（P〈0.05）.OFL group could significantly increase the content of CD4^＋ and the ratio of CD4^＋ and CD8^＋ in blood and decrease the content of CD8^＋ in blood（P〈0.05）.These results indicated that feeding diets containing CFPF,YE,SS and OFL can increase ADG,ADFI and decrease F/G of broiler chicks,and strengthen the body＇s immune function.In decreasing the concentration of ammonia in the broiler house and improving the breeding environment,SS and OFL can achieve or even exceed CFPF and YE. |
