摘　　要：应用冻干制品加速热稳定性试验,测试三组冻干保护剂配方对鸡传染性支气管炎(H120株)活疫苗的耐热保护效果。结果表明A配方的耐热保护剂效果最好,使用该保护剂的疫苗表现为37℃放置10d后,病毒含量下降在0.6~0.8个滴度。This experimentwas conducted to evaluatethe heat-resisting preventiveeffects of three differentfreeze-drying protectiveadditives on infectious bronchitis of broilers throughaccelerated thermostabilitytest. The results showed thatthe A formula was the bestheat-resisting protectiveagent, which declined by 0.6~ 0.8 unit when placed at 37℃ for 10 days.
