| Diclazuril grams/ton | Combination grams/ton | Indications for use | Limitations | Sponsor |
|---|---|---|---|---|
| (i) 0.91 (1 part per million (ppm)) | 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. Not for use in hens producing eggs for human food. | 016592 | |
| (ii) 0.91 (1 ppm) | Bacitracin methylene disalicylate 4 to 50 | Broiler chickens: As in item (i) of this table; for increased rate of weight gain and improved feed efficiency. | As in item (i) of this table. Bacitracin methylene disalicylate provided by 046573. | 016592 |
| (iii) 0.91 (1 ppm). | Bacitracin methylene disalicylate 50 plus roxarsone 22.7 to 45.4 | Broiler chickens: As in item (i) of this table; as an aid in the prevention of necrotic enteritis caused or complicated by Clostridium spp. or other organisms susceptible to bacitracin; for increased rate of weight gain, improved feed efficiency, and improved pigmentation. | Feed continuously as the sole ration throughout growing period. Use as sole source of organic arsenic; drug overdose or lack of water may result in leg weakness. Not for use in hens producing eggs for human consumption. Withdraw 5 days before slaughter. Bacitracin methylene disalicylate and roxarsone provided by No. 046573 in § 510.600(c) of this chapter. | 016592 |
| (iv) 0.91 (1 ppm). | Bacitracin methylene disalicylate 100 to 200 plus roxarsone 22.7 to 45.4 | Broiler chickens: As in item (i) of this table; as an aid in the control of necrotic enteritis caused or complicated by Clostridium spp. or other organisms susceptible to bacitracin; for increased rate of weight gain, improved feed efficiency, and improved pigmentation. | Feed continuously as the sole ration throughout growing period. Start at first clinical signs of disease; vary dosage of bacitracin based on severity of infection; administer continuously for 5 to 7 days or as long as clinical signs persist, then reduce bacitracin to prevention level (50 grams per ton (g/ton). Use as sole source of organic arsenic; drug overdose or lack of water may result in leg weakness. Not for use in hens producing eggs for human consumption. Withdraw 5 days before slaughter.
