Abstract

Maternal antibodies in egg yolks provide the initial protection for embryos after hatching. Newcastle disease virus is one of the viruses that causes mortality in chickens of all ages. This study aimed to analyze the Newcastle Disease virus titer in the egg yolks of IPB-D2 chickens (Institut Pertanian Bogor-D2). Seventy-two eggs were collected from 12 IPB-D2 chickens with two repetitions over three periods, using hemagglutination test for Newcastle disease titer. The hemagglutination test results were analyzed using geometric mean titers and descriptive analysis. The protection levels for Period I were 55%, Period II were 71%, and Period III were 70%. The egg weight was 40.11±3.61 grams, hatch weight was 32.12±4.62 grams, and body weight at 4 weeks was 288.2±59.42 grams. Phenotypic correlation of Newcastle antibody in egg yolks with egg weight and hatch weight showed significant differences but not statistically significant with body weight at 4 weeks.
