Diclazuril grams/ton	Combination grams/ton	Indications for use	Limitations	Sponsor	(i) 0.91		Broiler chickens: For the prevention of coccidiosis caused by Eimeria tenella, E. necatrix, E. acervulina, E. brunetti, E. mitis (mivati), and E. maxima. Because diclazuril is effective against E. maxima later in its life cycle, subclinical intestinal lesions may be present for a short time after infection. Diclazuril was shown in studies to reduce lesion scores and improve performance and health of birds challenged with E. maxima	Feed continuously as the sole ration. Do not feed to birds producing eggs for human consumption	058198	(ii) 0.91	Bacitracin methylenedisalicylate, 4 to 50	Broiler chickens: For the prevention of coccidiosis caused by Eimeria tenella, E. necatrix, E. acervulina, E. brunetti, E. mitis (mivati), and E. maxima, and for increased rate of weight gain and improved feed efficiency. Because diclazuril is effective against E. maxima later in its life cycle, subclinical intestinal lesions may be present for a short time after infection. Diclazuril was shown in studies to reduce lesion scores and improve performance and health of birds challenged with E. maxima	Feed continuously as the sole ration.
