摘要
为评价脱氢乙酸钠作为饲料防霉剂使用的安全性,以黄羽肉鸡为研究对象,分别饲喂含0、0.02%、0.10%、0.20%脱氢乙酸钠的日粮35 d,检测增重、器官指数、血常规及血液生化指标,并对主要脏器进行病理学分析。结果表明:除0.20%处理组试验前期增重极显著低于对照组外,0.20%处理组试验后期及0.10%和0.02%处理组增重均无显著差异。各处理组血常规与对照组相比无显著差异;除0.20%处理组血液总蛋白、球蛋白显著高于对照组及葡萄糖显著低于对照组外,其他生化指标与对照组差异不显著。除0.20%处理组肝指数显著高于对照组、法氏囊指数显著低于对照组外,其他器官指数无显著差异。心、肝、脾、肺、肾及法氏囊组织,HE染色分析均未发现明显的组织学改变。这一研究说明添加0.02%脱氢乙酸钠于饲料中对肉鸡生长无明显影响。
To evaluate the safety of sodium dehydroacetate used as feed fungicide,yellow broilers were selected to feed diet supplemented with 0,0.02%,0.10%,0.20% sodium dehydroacetate for duration of 35 days.The body gain,organ index,index of blood routine and blood biochemical and histopathological were analyzed.Results showed the body gain in 0.02% and 0.10% groups had no significant difference compared to control（P0.05）,same in 0.20% group at latest weeks except that body gain in 0.20% group at early 2 weeks was significantly lower than that of the control（P0.01）.There was no significant difference in index of blood routine between three tested groups with the control.The serum content of total protein and globulin in 0.20% groups were significantly higher than those in the control,glucose was significantly lower than the control group.Other blood biochemical indexes displayed no significant difference.The liver index of the 0.20% groups was significantly higher than that of the control（P0.05）,while the bursa index was significantly lower than that of the control（P0.05）.Conclusion was that no obvious effect on growth of broilers was appeared when 0.02% sodium dehydroacetate was added in feed.
