摘要
通过对 3种不同配方的冻干保护剂和冻干曲线与猪瘟兔化弱毒相溶性的比较研究 ,成功研制了适用于猪瘟淋脾毒活疫苗的耐热保护剂。用这种保护剂生产的该疫苗经 37℃保存1 0d的耐老化试验及在 2～ 8℃保存 1 2个月后仍然符合产品质量标准的要求。经 4770余头份疫苗的田间试验 ,证明该产品安全、有效 ,且便于运输和使用 ,显示出良好的热稳定性能。
The thermostability of thermo-tolerant freeze-dried live hog cholera lapinized virus(HCLV) (vaccine) was studied with different suspending media and freeze-drying system. The vaccine was still effective when stored at (2～8 ℃) for 12 months or stored at 37 ℃ for 10 days. After field experiment about 4 770 dose (vaccine used, )the (results) showed that the vaccine was effective against hog cholera and safe to pigs.
