摘要: 传染性支气管炎能引起鸡的急性、高度接触性的呼吸道、消化道和泌尿生殖道疾病,对我国养鸡业构成严重威胁。而新城疫也是危害我国养鸡业的重要传染病。疫苗免疫是公认的预防这2种疫病的方法。本研究利用自制的3批ND-IB二联灭活疫苗,分别对28日龄易感雏鸡和120日龄开产前母鸡进行免疫,利用HI试验测出试验鸡群的抗体值。结果表明28日龄易感雏鸡在2个月内,开产前母鸡在3个月内均受到有效保护,为本批新支二联疫苗的实际临床免疫接种提供了依据。 

Abstract: Infectious Bronchitis which can cause acute, highly contact disease of the respiratory, digestive and genitourinary tract of chicken, has posed a serious threat on our poultry industry. While the Newcastle Disease has been the most of principal enemy to China’s chicken industry over the years. Vaccine immunization is internationally recognized as a prevention way of the two diseases. In this experiment, the dual inactivated vaccine Newcastle Disease and Infectious Bronchitis was made and used to immune the 28-day-old chick and 120-day-old hen. Then ND and IB antibody value was evaluated by using HI test. The results indicated that the vaccine’s immunization period is two months to susceptible chicken and three months to open prenatal hen. This provided practical evidence for clinical use of the vaccine.
