The immune effect of duplex inactivated vaccines of newcastle disease and infectious bursal disease on SPF chicken and commercial broiler
摘要
Abstract
1, 7, 14 days of age SPF chicken are respectively vaccinated with a new, efficient inactivated vaccine of infectious bursal disease, and group 1 of chicken immune at 1 day-age, blood collecting at 25 days-age, the neutralizing antibody is up to15.5log2, poison attack protection reaches 10/10; group 2 of chicken immune at 7 days-age, blood collecting at 30 days-age, the neutralizing antibody is up to 14.8log2, poison attack protection reaches 10/10; group 3 of chicken immune at 14 days-age, blood collecting at 35 days-age, the neutralizing antibody is up to 15.4log2, poison attack protection reaches 10/10.At 50 days-age of three groups chickenˊs neutralizing antibody are respectively up to16log2,16.1log2 and15.9log2, and poison attack protection all reaches 10/10. A new, effi-cient inactivated vaccine immune 1, 7, 14 days old commercial broilers with maternal antibody, after 25 days, sera-neutralizing anti-bodies are respectively up to 12.4log2, 15log2 and 14.2log2, poison attack protection respectively reach 8/10, 10/10 and 9/10; Three groups commercial broilers at the age of 50 days,their neutralizing antibody titers are respectively up to16.2log2,15.7log2,15.5log2, and poison attack protection reaches all 10/10.关键词
