| dc.description.abstract | Native chickens are more likely to become domesticated livestock and
industrial livestock that cannot be replaced by other types of chicken. IPB-D1
chickens are a new breed of native Indonesian chickens created by cross-breeding
native chickens and broiler parent stock. The IPB D1 chicken has a high
concentration of immunoglobulin IgY and resistance again Newcastle disease
infection. IPB D2 chickens are a potential candidate for a new line of selection
results from IPB D1 chickens for disease resistance and fast growth. Helminthiasis
is a disease caused by helminth infection that causes health problems such as lose
weight and production decrease. Helminthiasis can reduce the immune system, so
it is necessary to research to determine the IgY concentration of IPB D2 chicken in
chickens with various levels of helminth infection. The study aims to investigate
the IgY infection in various helminth infections. Twenty-two chickens IPB D2
chicken 27-week-old were used for this research. The faecal and blood sample were
collected. Observed data is obtained from blood and faecal sample. The Ig Y titer
was measured by the ELISA method, and the presence of helminth was observed
by McMaster and simple flotation technique. The result shows that the IgY
concentration of IPB D2 chicken was 5.6-12.36 mg/mL, 65% of the chicken was
categorized as a high titer of IgY, i.e., > 7.5 mg/mL and the rest (35%) categorized
low titer (< 7,5mg/mL). The egg of nematode and cestode was found in the chicken.
The genus that was found is Strongyloides, Trichuris and Capillaria. Other
gastrointestinal parasites include oocytes and protozoa of the genus Eimeria.
Chicken with a high IgY titer has higher infection than chicken with a low IgY. It
is indicated that helminth infection induces antibodies by increasing the IgY titer | id |
