Safety evaluation of lasalocid use in Chinese ring-necked pheasants ( Phasianus colchicus ) . Coccidiosis remains a significant threat to the welfare of game farm-reared pheasants in the United States . Although lasalocid has been demonstrated to be effective against pheasant specific coccidia , information regarding its safety in this species is lacking . The purpose of this study was to gather data on the safety of lasalocid when fed to Chinese ring-necked pheasants at one , two , and three times the recommended high dose of lasalocid used for prevention of coccidiosis in other poultry at three times the normal treatment period . Pheasant chicks ( approximately 1 day-old ; n = 160 ) were randomly blocked by sex into four treatment groups and given their respective diets continuously for 6 wk . No significant differences were observed in overall feed consumption , weight gain , feed conversion rates , clinical pathology measurements , or tissue gross and histopathologic evaluations between controls and treatment groups associated with lasalocid administration . Based on the results of this study it appears that lasalocid fed at the recommended rate of 125 ppm is safe in Chinese ring-necked pheasants .
