Popis: | The research work was performed to investigate the immunogenicity of Salmonella vaccine produced at LPVRPC, BAU Mymensingh. The vaccination was performed at the Phenix Hatchery Ltd. Gazipur in Hy-sex brown and HY-sex white chicken designated as group A and group B respectively. Group A and B were subdivided into A1, A2, A3, B1, B2 and B3 groups containing eight birds each. Group C was maintained as unvaccinated control. Birds were immunized following schedule of the LPVRPC. Each bird was vaccinated SC at six weeks of age followed by a subsequent booster dose after 45 days. After four weeks of primary vaccination the mean PHA antibody titres were 96.00±34.21 in group A1 and 96.00±34.21 in B1 group. Prebooster vaccination the mean PHA antibody titres were 88.00±33.12 in group A2 and 88.00±33.12 in B2 group. At four weeks of booster vaccination the mean PHA antibody titres were 104.00±33.12 in group A3 and 104.00±33.12 in B3 group. The mean ± PHA antibody titre in chickens of group C was ? 4.0±0.00. Salmonella vaccine prepared at (LPVRPC) Department of Microbiology and Hygiene, BAU induces satisfactory level of antibody in chickens determined by PHA test conducted in an on-farm study of layer chickens.DOI: http://dx.doi.org/10.3329/bjvm.v13i1.23705Bangl.
