Production Performance and Humoral Immunity in IPB-D3 Chickens

Abstract

This research were conducted analyzed antibodi in IPB-D3 chickens on production performance. Pedigree data and information were collected in generations 3 and 4. In the third generation, as many as 36 chickens (9 males and 27 females) aged 27 weeks and 162 IPB-D3 chicken eggs, in the fourth generation aged DOC and 2 weeks, each 81 samples. Total Immunoglobulin yolk (IgY) observations were made using Enzyme Linked Immunosorbent Assay (ELISA) and antibody titer against Newcastle disease virus (AbNDV) methods using Hemaglutination Inhibition (HI) tests. Descriptive analysis was performed on production performance data and humoral immunity to estimate phenotypic correlation of the statistical method of Pearson correlation analysis. The results of IgY examination in men aged 27 weeks were 9.49 ± 1.37 mg/mL and IgY in women 9.36 ± 2.89 mg/mL. AbNDV ages 0 and 2 weeks at 1.34±0.95 and 1,370.95 LOG 2 GMT. At the age of 12 weeks, the body weight of IPB-D3 chickens of G4 males is higher than that of G3 males, which is 1021.44±60.05 grams with a CV of 17.01%. Total egg production in a day in the age range of 29-40 weeks is 13.3±7.56 eggs, with a production percentage of 44.8%. Phenotypic correlation between IgY aged 0-2 with active body weight of IPB-D3 chickens aged 0 to 12 weeks showed positive but low to moderate values of 0,06-0,49. In conclusion, humoral immunity such as IgY and AbNDV did not have a significant effect on the growth and production of IPB-D3 chickens.
