Abstract:
In this study, the sero-prevalence of Mycoplasma synoviae (MS) was carried out in breeder flocks of different age groups. A total of 171 serum samples were collected from 14 broiler parent flocks, out of which 57.80% (99/171) were positive for MS antibodies. The prevalence of MS antibodies was 21.25% (17/80) in breeder flocks of young age (0 to 20 weeks), with a mean titer of 1024.9 and a titer range of 0 to 6432. Similarly, the prevalence of MS antibodies was 90.1% (82/91) in breeder flocks of adult age (21 to 60 weeks), with a mean titer of 4390 and a titer range of 0 to 13511. The study showed that the number of positive sera for MS was higher in birds aged 21 to 60 weeks than in birds of 0 to 20 weeks age and indicated that the seroprevalence of MS increased with the increase age of the birds.
