摘要

為了規劃更佳的肉雞健康策略，於1989年進行432戶肉雞和35戶種雞場的流行病學資料的調查。此調查結果發現雞舍間的最短距離、每一萬隻雞的獸醫服務、藥品與疫苗的支出等，在地區間有不等程度的顯著差異。慢性呼吸器病（CRD）是肉雞和種雞產業中最常見的疾病。迴歸分析結果顯示，白肉雞和色雞的CRD死亡率和育成率；白肉雞的CRD死亡率和飼料換肉率呈相關。後勤分析結果顯示白肉雞和色雞的CRD發生和統進統出；球蟲病的發生和飼養期間、地區呈相關。

In order to design better strategies for Taiwan's broiler health, a survey covering 432 broiler rearing and 35 breeding farms was conducted in 1989 to collect detailed epidemiological data. This survey revealed that shortest distance between chicken houses, number of veterinarians per 10,000 chicken reared, drug and vaccine expenditure were different significantly in different prefectures studied, Chronic respiratory disease (CRD) was the most frequently recorded disease in both broiler rearing and breeding industries. Results from regression analysis showed that CRD mortality rate and survival rate in both WB and CB farms; CRD mortality rate and feed conversion ratio in WB farms were correlated. Results from logistic analysis showed that occurrence of CRD and ”all-in all-out” system; occurrence of coccidiosis and raising period, region in both WB and CB farms were correlated.
