Genotype effect on distribution pattern of maternally derived antibody against Newcastle disease in Nigerian local chickens.

Abstract
This study was conducted to evaluate the variation in antibody from Newcastle disease (ND) vaccinated breeder birds and their progenies. The chicks were evaluated for maternally derived antibody (MDA) against ND virus and also the MDA transfer rate for each genotype. The local parent stocks were Frizzle-feathered, Normal-feathered, and Naked neck while an exotic parent stock (Anak Titan) was used for the purpose of comparison. Sera samples were collected from chicks generated at day 3 post-hatch, and sera were also collected from the parent stocks. The sera samples were stored at -20 °C until analysed. Enzyme linked immuno-sorbent assay (ELISA) test was used for the detection and quantification of antibodies to ND in the parent stocks and the chicks using IDEXX Newcastle Disease ELISA test kit. The least squares means of antibody titers for parent stocks were 413.333 ± 68.853, 426.333 ± 121.949, 481.667 ± 145.454, and 1148.333 ± 532.843 for Frizzle-feathered, Normal-feathered, Naked Neck, and Anak Titan, and the calculated MDA transfer rate was 96.4, 93.8, 88.7, and 34.7 % for Frizzle-feathered, Normal-feathered, Naked neck, and Anak Titan, respectively. The mean antibody titers for chicks were 398.6 ± 43.871, 400.0 ± 53.952, 427.0 ± 89.353, and 398.8 ± 57.593 for Frizzle-feathered, Normal-feathered, Naked neck, and Anak Titan, respectively. The antibody titers from parent stocks were higher than those observed in chicks for all the genotypes. The values obtained in this study indicated that parent stocks with their progenies were below protective level. The local parent stocks had higher transfer rate when compared to their exotic counterpart. Hence, there is an indication from this finding that the local chickens had a better transfer rate in relation to Anak Titan which is an exotic breed. Therefore, there is the presence of genetic variability for antibody transfer in the Nigerian local chickens and can be incorporated in designing a breeding program for better adaptive potential.
