likely to occur in broiler chickens and replacement chickens where
immunity to coccidiosis is not desired, and for increased rate of
weight gain in broiler chickens raised in floor pens; (2) as an aid in
the prevention of coccidiosis where severe exposure to coccidiosis from
Eimeria acervulina, E. maxima, and E. brunetti is likely to occur; and
(3) for improved feed efficiency in broiler chickens.
