title: Comparison of low-level rofenaid, low-level chlortetracycline, and vaccination with commercial bacterin for preventing pulmonary form of fowl cholera in turkeys.
abstract: The pulmonary form of experimentally induced fowl cholera was controlled effectively either by Rofenaid, a potentiated sulfadimethoxine, at 0.01% in feed, chlortetracycline at 0.0055% in feed, vaccination with a commercial fowl cholera bacterin and a combination of Rofenaid and vaccination. The medicated or/and vaccinated turkeys had a significantly (P less than 0.05) better livability than the unmedicated or unvaccinated exposed turkeys. Turkeys were exposed by contact with carriers and administration of Pasteurella multocida in drinking water. Transmission from carriers to recipients through the water was demonstrated. P. multocida was isolated from the mouths of recipient turkeys receiving low-level medication one week after carriers were introduced.
