摘要
应用五州药厂生产的快大灵抗生素饲料添加剂饲喂肉用仔鸡,经60天960羽小试,在日增重、料肉比、育成率及经济效益诸方面筛选出50ppm快大灵添加剂组为最佳剂量组;又经两批6700羽鸡中试,进一步证明:大群肉用仔鸡饲喂后,肉鸡增重10.50％(P<0.05),提高饲料利用率7.98％,降低死亡率27.60％,提高经济效益24.96％。与同类产品威霸先进行对比试验,两者在多项指标上比较没有显著差异。随机取样68羽肉用仔鸡屠宰,大体剖检及病理组织学测定,结果未见异常病变,均属正常范围;采集肌肉、肝脏、血清经生物鉴定法进行药物残留测定,结果只要在鸡上市两天前停止喂药,则不再有抗生素药物残留。
An antibiotic feed additive named Luai-Da-Ling was used to feed broilers. In first trial, 960 chickens were fed with for 60 days. The result showed that the optimum concentration of the additive to be supplemented in the ration was 50ppm. In second trial, 6700 chickens were used. The result showed that the gain increased 10.50％(P<0.05), feed efficiency increased 7.98％, mortality reduced 27.6％ and the profit increased 24.96％. It was also proved that the Ruai-Da-Ling was as effective as Vibravet in improving the growth rate of broiler. Histologigal examination indieated that no residue of antibiotic was detected if the additive was withdrawn two day before the animal was killed.
