近几年来,北京地区很多鸡场的中雏鸡(7周龄左右)发生白痢病,由白痢沙门氏菌(Salmonella pullorum)引起,病理变化与禽伤寒相似,但发病率与死亡率较高,与雏鸡白痢病(4周龄以内)和Cosgrove(1961)及温俊板等(1985)曾报道的关节炎型中雏白痢... 近几年来,北京地区很多鸡场的中雏鸡(7周龄左右)发生白痢病,由白痢沙门氏菌(Salmonella pullorum)引起,病理变化与禽伤寒相似,但发病率与死亡率较高,与雏鸡白痢病(4周龄以内)和Cosgrove(1961)及温俊板等(1985)曾报道的关节炎型中雏白痢病不同。为了掌握本病的病原学特点,提供微生物诊断与防制依据,我们进行了中雏鸡的人工感染试验。 展开更多

中雏鸡一般是指2个月龄至开产前的鸡,已能适应外界环境条件和独立生活。它的生理特点是消化系统逐渐趋于发达,是长骨胳、长肌肉、长羽毛阶段,是鸡一生中增重量快的时期。中雏鸡的饲养管理的任务是使鸡群发育良好和保持健康的的体质,为... 中雏鸡一般是指2个月龄至开产前的鸡,已能适应外界环境条件和独立生活。它的生理特点是消化系统逐渐趋于发达,是长骨胳、长肌肉、长羽毛阶段,是鸡一生中增重量快的时期。中雏鸡的饲养管理的任务是使鸡群发育良好和保持健康的的体质,为产蛋打下良好的基础,因此应着重抓好如下几点: 第一,及时分群,注意饲养密度。 在育雏期间,由于雏鸡出壳的迟早。体质的强弱、开食的早晚、生长发育的好坏以及有无疾病的影响,雏鸡的生长发育有快有慢,体质有强有弱。 展开更多

[ Objective] The aim of this study was to lay a foundation for obtaining effective traditional Chinese medicine preparations controlling chicken colibacillosis. [ Method] With the western medicine Lomeflbxacin Hydrochloride and Sodium Chloride Injection as the control, drug sensitivity tests of 15 single traditional Chinese herbs and seven self-made Chinese herbal compounds were conducted. Subsequently, the single traditional Chinese herbs presenting good in vitro antibacterial effects against Escherichia coli and all the seven compounds were given to the chicks artificially infected with E. coil to observe their efficacies. [ Result] The results of drug sensitivity tests showed that all the 15 traditional Chinese herbs had certain antibacterial effect against E. coli, among which aloe, pomegranate rind and radix sanguisorbae were the best. Compound 1, 2 and 5 had good antibacterial effects in vitro. By in vivo test, traditional Chinese medicines showed superior efficacies on infected chicks than western medicine, and compound 1 and 2 performed well. [ConclusiOn] Traditional Chinese medicine preparations are good at controlling Chicken colibacillosis, but their bacteriostasis mechanism in vivo was different with that in vitro. 展开更多
