Evaluation of Aureomycin for prevention of arthritic, pulmonary and cranial forms of fowl cholera in turkeys.

Aureomycin fed at concentrations of 55, 110, and 220 mg./kg. of feed significantly (P less than 0.05) increased livability as compared to that of the nonmedicated exposed and increased average body wieght gained per turkey as compared to that of both the nonmedicated exposed and nonmedicated nonexposed turkeys. The increase in survival was proportional to the increase in concentration of Aureomycin in the feed. Turkeys were exposed, in the drinking water, to three isolates of Pasteurella multocida which had inclinations for localizing in the joints, lungs, and air spaces of the head. There were no carriers of P. multocida in either the medicated or nonmedicated turkeys three weeks after exposure.
