摘　　要：本试验对牛病毒性腹泻病毒BVDV2/JZ05-1活疫苗对犊牛最小免疫剂量及攻毒保护效果进行了研究。对BVDV2/JZ05-1活疫苗进行倍比稀释后免疫犊牛,在免疫后第28天用BVDV/JL-1强毒株进行攻毒保护试验研究。结果表明,牛病毒性腹泻病毒BVDV2/JZ05-1活疫苗对犊牛的最小免疫剂量是105.0TCID50/mL。The calves were vaccinated with BVDV2/JZ05 - 1 live vaccine by different immune dose. The calves were challenged with BVDV/JL - 1 after 28 days after immunization. The results suggest that the minimum immune dose of BVDV2/JZ05 - 1 live vaccine islOS^TCIDso/mL.
