Hypothetical remarks about the resistance of local native Bangladeshi chickens were compared with an exotic breed like Fayoumi towards Gumboro disease. A reserve experimental result was obtained with increased susceptibility of the locals than the exotics. Poor bursal enlargement along with the absence of many post-mortem lesions and peculiar hepatomegally were notable post-mortem lesions in locals. Maternal antibody attains a zero level as detected at 19 days of age by agar gel precipitation test. Materiality in locals 46% and exotic 38% was encountered in both the breeds following challenge with a virulent field isolate of Gumboro disease virus. Onset of morbidity proceeded in the locals. A spiking death curve was observed in both the breeds. Mortality started since day 2 following challenge and continued till day 5 except in the locals, where it ended on day 3 post challenge. It is assumed that changes in the method of feeding and rearing may act as natural stress affecting the cell-mediated immunity related to genetics and perhaps rendered them more susceptible. |
