Abstract:
In a series of experiments, leghorn-type chickens were fed diets containing from 0 to 880 mg of ascorbic acid/kg of feed beginning 1 day before air-sac challenge with Escherichia coli. Infection occurred in 46/60 (76%) of the controls and in 12/63 (19%) of those given feed containing 330 mg of ascorbic acid/kg. Levels of ascorbic acid above and below 330 mg/kg feed were less effective.
