- Abstract
The disease was established on a poultry dressing combine, affecting birds at the age of three to eleven weeks. It ran its course with clinical symptoms and epizootiology that were characteristic of it. A total of 8778 birds or 10% succumbed to the disease. Its notification on a newly built poultry dressing combine made it reasonable to believe that possibility existed of its transmission through the hatcheries. The outbreak occurred almost simultaneously with the inadequate feeding that was admitted on the combine. The cyclogramme concerning the admission of birds and its strict application were shown to influence the course of the epizootic process. Clinical and epizootiological investigations coupled with virological and histopathological studies rendered it possible to draw the conclusion that the birds on the combine were affected with infectious bursitis, identified as Gumboro disease. It was established for the first time in this country.
