| 中文摘要: |
| 诺维氏梭菌导致的猪只猝死是集团规模猪场母猪和育肥猪猝死的重要原因。试验在华北地区某集团各选择1 200头育肥猪，应用某厂家猪大肠杆菌-C型产气荚膜梭菌-诺维氏梭菌三联灭活疫苗H和另一厂家产气荚膜梭菌二价疫苗（A型、C型）Z进行预防猪只胀气猝死的效果比较。结果表明：免疫三联灭活疫苗H组死亡率下降3.25个百分点，免疫二价疫苗Z组死亡率下降2个百分点，猪只因诺维氏梭菌导致的猝死比例显著下降，有效提高了猪场经济效益。 |
| 英文摘要: |
| Clostridium novyi is a significant cause of sudden death in sows and fattening pigs. The aim of this trial was to compare the effect of sudden death prevention between two commercial vaccine: vaccine H (a triple vaccine against enteropathogenic Escherichia coli, Clostridium perfringens type C and Clostridium novyi) and vaccine Z (a bivalent vaccine against Clostridium perfringens type A and type C).This trail was performed with 2 400 fattening pigs (1 200 every group) in a northern breeding farm. The results demonstrated that: 3.25 percent reduction of the mortality presented in group of vaccine H, 2 percent reduction in group of vaccine Z. The mortality of sudden death caused by C.novyi has been significantly reduced. The economic benefits was improved effectively. |
