title: [Effect of sulfaquinoxaline and diaveridine on leucocytozoon infection in chickens].
abstract: The preventive effect of sulfaquinoxaline and diaveridine in combination against leucocytozoon infection in White Leghorn female chickens was tested in a field trial. The experiment was initiated when the animals were 120 days old, and it lasted for 10 weeks. The medication was given for the first seven days, and no medication was given for the next seven days; then this schedule for the medication was repeated throughout the experimental period. The almost complete preventive effect was obtained when sulfaquinoxaline and diaveridine were added to the feed at the level of 16 ppm and 4 ppm, respectively, or at the level of 8 ppm and 2 ppm, respectively. On the other hand, only a partial effect was obtained when these drugs were used at the level of 4 ppm and 1 ppm, respectively. These medications had no adverse effect on the weight gain in the experimental birds.
