§ 558.205 Diclazuril.

(a) Specifications. Type A medicated article containing 0.2 percent diclazuril.

(b) Sponsor. See No. 058198 in § 510.600(c) of this chapter.

(c) Related tolerances. See § 556.185 of this chapter.

(d) Conditions of use - (1) Chickens. For chickens it is used as follows:

Diclazuril
grams/ton
Combination in 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 Feed continuously. Not for use in hens producing eggs for human food. 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 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 Feed continuously. Not for use in hens producing eggs for human food. 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. Bacitracin methylenedisalicylate as provided by No. 054771 in § 510.600(c) of this chapter 058198
(iii) 0.91 Bambermycins, 1 to 2 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 Feed continuously. Not for use in hens producing eggs for human food.
