鸡组织滴虫病诊断与防治

Diagnosis and Control of Chicken Tissue Trichomoniasis

鸡组织滴虫病又被称为黑头病或者传染性盲肠肝炎,是一种急性原虫病,常发生于家禽养殖领域,具有很高的感染率和发病率,其中对15~60日龄的雏鸡造成的危害最为严重,会严重影响鸡生长发育,使养殖场淘汰率显著升高。成年鸡受到病原侵染后,会表现为生产性能下降,产蛋率下降,畸形蛋率显著升高,但大多数成年鸡不会表现出明显的临床症状。鸡组织滴虫病的发生流行具有典型的季节性,常发生在夏秋高温季节,发病率和死亡率进一步提升,给养殖户造成巨大经济损失,威胁家禽养殖产业的安全。

Chicken trichomoniasis,also known as black head disease or infectious cecal hepatitis,is an acute protozoan disease that often occurs in poultry farming and has a high incidence of infection,among them,15~60 day-old chicks are the most seriously harmed,which will seriously affect the growth and development of chickens and increase the culling rate of the farm significantly.When adult chickens were infected by pathogens,the production performance and egg laying rate decreased,and the abnormal egg rate increased significantly,but most adult chickens did not show obvious clinical symptoms.The epidemic of histomonas meleagridis is a typical seasonal disease,which often occurs in summer and autumn and high temperature season.The morbidity and mortality of histomonas meleagridis are further increased,which causes huge economic losses to poultry farmers and threatens the safety of poultry breeding industry.
