The study was carried out at Veterinary University Training and Research Centre, Tiruchirapalli, Tamil Nadu. A total of 48 day old desi chicks obtained from a private hatchery in Namakkal, TamilNadu were maintained under cage system of rearing up to 52 weeks of age as per standard management practices. All the 48 chicks were divided into six groups having eight chicks in each group were subjected to different treatment regimes. Ten eggs from each group were randomly collected during the last three days of eight weeks interval period from 28 weeks to 52 weeks of age and were used to measure the egg quality parameters. In all the six treatment groups with respect to egg shell thickness and Haugh unit no significant difference (P ≥ 0.05) was noticed from 28 weeks to 52 weeks of age. From this study, it is concluded that the administration of Newcastle disease oral pellet vaccine to desi chicken does not affect the egg qualities like egg shell thickness and Haugh unit.
