Sulfaquinoxaline in grams/ton	Indications for use	Limitations	Sponsor
(i) 0.015 percent	As an aid in preventing outbreaks of coccidiosis caused by Eimeria tenella, E. necatrix, E. acervulina, E. maxima, and E. brunetti under average conditions of exposure	Feed continuously from the time birds are placed on litter and continue past the age when coccidiosis is ordinarily a hazard. If death losses exceed 0.5 percent in a 2-day period, obtain a laboratory diagnosis. If coccidiosis is the cause, use the sulfaquinoxaline levels recommended for control of outbreaks, returning to the original dosage schedule after the outbreak has subsided. Losses may result from intercurrent disease, other conditions affecting drug intake, or variant strains of coccidia species which can contribute to the virulence of coccidiosis under field conditions. Do not treat chickens within 10 days of slaughter. Do not medicate chickens producing eggs for human consumption	016592
(ii) 0.0175 percent	As an aid in preventing outbreaks of coccidiosis caused by Eimeria tenella, E. necatrix, E. acervulina, E. maxima, and E. brunetti where excessive exposure to coccidia is increased due to overcrowding or other management factors	Feed continuously from the time birds are placed on litter and continue past the age when coccidiosis is ordinarily a hazard. If death losses exceed 0.5 percent in a 2-day period, obtain a laboratory diagnosis. If coccidiosis is the cause, use the sulfaquinoxaline levels recommended for control of outbreaks, returning to the original dosage schedule after the outbreak has subsided.
