Abstract

Ring-necked pheasants are raised on farms under conditions similar to commercial production of poultry. They are routinely infected with coccidia that cause outbreaks of disease and sometimes death. Amprolium is the only approved drug for use against coccidiosis in this species and resistance has been reported. Lasalocid (Avatec®) is approved for use in chickens, turkeys and partridges for the prevention of coccidiosis caused by Eimeria species specific for these birds. It is used extra-label on pheasant farms and has been shown to be effective against coccidia that cause disease on pheasant farms. In order to add pheasants to the Avatec® label, information regarding its efficacy and safety is required by the U.S Food and Drug Administration. The current work focused on evaluating lasalocid use in pheasants at 1, 2 and 3 times the labeled high dose for treatment of coccidia in other avian species.
