Abstract

The New castle disease maternal antibody and HI antibody of 1~28-day-age Broiler chicken and Luoman chicken were respectively detected to institute this scientific immune program.New castle disease freeze dried vaccine and oil emulsion vaccine were used in the test.The results showed that the maternal antibody level was highest in 1-day-age chicken and declined gradually.The maternal antibody of Broiler chicken decreased to 5.2log2 in 11-day-age and that of Luoman chicken was decreased to 4.3log2 in 28-day-age.Broiler chicken and Luoman chicken could get high HI antibody level by respectively first immunized in 12-day-age and 11-day-age.The immune program used in the test could efficiently prevent new castle disease.
