有不少養雞戶自以為有多年養肉雞的經驗，雞發病後常自己購藥治療，但療效大多不理想。筆者認為其原因有以下幾種：

對雞病診斷不確切

有些養雞戶對雞病認識一知半解

，如一見包心包肝，就認為是大腸杆菌病；一見腺胃乳頭出血

，就判斷是新城疫……shubuzhi

不明病因亂用藥

雞ji群qun發fa病bing開kai始shi死si亡wang，養yang雞ji戶hu往wang往wang未wei明ming病bing因yin就jiu亂luan用yong藥yao物wu，不bu但dan沒mei能neng把ba病bing治zhi好hao，還hai因yin得de不bu到dao及ji時shi準zhun確que的de治zhi療liao
，而er使shi病bing情qing加jia重zhong，死si亡wang數shu增zeng加jia。如ru發fa現xian雞ji拉la稀xi就jiu用yong恩en諾nuo沙sha星xing等deng藥yao物wu。其qi實shi，雞ji咳ke嗽sou有you可ke能neng是shi得de了le支zhi原yuan體ti病bing
，也ye有you可ke能neng是shi喉hou氣qi管guan炎yan
、支氣管炎
、新城疫、禽流感等；雞拉稀不但有可能是沙門氏杆菌病，也有可能是大腸杆菌病或各種病毒感染。不查明病因就用藥是起不到治療作用的。

停藥過早，造成病情反複

，以鞏固療效，以達到治愈疾病的目的。

隨意加大用藥量

雞病從開始用藥治療到治愈需要有一個過程，即療程。一個療程一般要3～5天tian。少shao數shu養yang雞ji戶hu企qi圖tu通tong過guo加jia大da用yong藥yao量liang，喂wei服fu一yi餐can或huo注zhu射she一yi次ci藥yao物wu就jiu能neng藥yao到dao病bing除chu，這zhe是shi不bu切qie合he實shi際ji的de。這zhe樣yang做zuo的de結jie果guo，不bu但dan不bu能neng一yi次ci性xing把ba雞ji病bing治zhi好hao

，反fan而er會hui因yin為wei用yong藥yao量liang過guo大da給gei雞ji群qun造zao成cheng毒du副fu作zuo用yong
，甚shen至zhi引yin起qi雞ji中zhong毒du死si亡wang。

聽病就防，見病用藥
