抗生素组合Respirend-M对肉仔鸡生产性能的影响
Effect of an antimicrobial association (Respirend-M) on productive performance of broilers
摘要：
本研究的目的是确定在0至14日龄的雄性肉鸡中饲喂抗菌剂组合对细菌过程的性能和临床体征的影响。测试了两种处理：不含Respirend-M的对照处理和含抗菌剂的处理（300 g/t Respirend-M，0-14 d）。将398只雄性Cobb 500雏鸡随机分配到两个处理组，每个处理组4个重复。对14日龄体重、增重、采食量、饲料转化率和健康状况进行评价。结果表明，添加300 g/t的Respirend-M显著（P<0.05）提高了肉鸡的终末增重、日增重和采食量。对饲料转化率无显著影响（P>0.05）。
英文摘要：
The objective of this study was to determine the effect of feeding an antimicrobial association to males broiler chickens from 0 to 14 days of age on the performance and clinical signs of bacterial processes. Two treatments were tested: a control treatment without Respirend-M, and a treatment with the antimicrobial (300 g/t Respirend-M, 0-14 d). 398 male Cobb 500 chicks were randomly assigned to two treatments and four replications per treatment. Body weight at 14 d, body weight gain, feed intake, feed conversion ratio, and health status were evaluated. The results showed feeding 300 g/t Respirend-M significantly (P<0.05) improved the final body weight, the body weight gain and the feed intake. No statistically significant (P>0.05) effect was detected on the feed conversion ratio.
