PREVALENCE OF SALMONELLA ANTIBODIES IN BREEDER CHICKEN AND ISOLATION OF SAME ORGANISM FROM THE EGGS AT DIFFERENT STAGES

Abstract

The present study was reflected on the prevalence of salmonella antibodies in breeder chicken and salmonella isolates from eggs at different stage. Eggs are collected from the selected Hatchery at different stages (at laying period, prior to incubation at hatchery, and the stage of incubation at 7 days, 14 days, for the isolation of Salmonella Spp. The prevalence of Salmonella antibodies were also determined from selected flocks by Rapid Serum Plate Agglutination test (RSPAT) using Salmonella Nobilis antigen. A total of 225 sera samples were tested by Rapid Serum Plate Agglutination (RSAPT) test to determine the prevalence of Salmonella antibodies in breeder chicken .The prevalence of Salmonella antibodies was 20% in group A, 24% in group B, and 28% in group C. The prevalence was highest recorded in group C (28%) followed by group B, (24%) and group A, (20%). An investigation was conducted on hatchery samples for the isolation of Salmonella spp. from eggs (Yolk interior, egg shell membrane). Salmonella organism were recorded from 33 of 100 (33%), 3 of 100(3%), samples of yolk interior, egg shell membrane.
