| 摘 要： | 对37℃持续热应激对实验性大肠杆菌病肉鸡生产性能的影响进行了研究,结果表明,热应激和大肠杆菌感染均可显著降低(P<0.01)肉鸡的采食量。热应激4~7 d感染肉鸡的采食量平均下降了26.01%(P<0.01)。热应激显著降低肉鸡的增重(P<0.01),大肠杆菌感染使肉鸡体重显著下降(P<0.01)。热应激7 d,感染肉鸡体重下降了348.58%。说明热应激显著降低感染肉鸡的采食量,严重影响感染肉鸡的生产性能。

| Abstract: | The experiment was designed to investigate effects of 37℃ constant heat stress on production efficiency in broiler chickens with experimental colibacillosis and to give the theoretics basis for breeding broiler chickens with colibacillsis under high temperature.The results showed that: the heat stress and colibacillosis in broiler chickens all decreased significantly(P<0.01) in feed intake.The feed intake of broiler chickens with colibacillsis decreased by 26.01%(P<0.01) from 4 to 7 day under heat stress.The heat stress decreased significantly(P<0.01) in body weight gain of broiler chickers.The body weight of broiler chickens with colibacillosis decreased significantly(P<0.01).The body weight in broiler chickens with colibacillosis decreased by 348.58% in 7 days under heat stress.The conclusion: The heat stress decreased significantly in feed intake of broiler chickens with colibacillosis and severely affected its production efficiency. |
