Turkey poult tolerance to diets containing deoxynivalenol (vomitoxin) and salinomycin

Feed taken from a commercial turkey farm where poults had refused to eat the feed and high mortality had occurred was analyzed and found to contain .81 mg/kg vomitoxin and 2.2 mg/kg salinomycin. The present four experiments investigated the effects of diets containing salinomycin at 0, 2.2, 5.5, 11, and 22 mg/kg and vomitoxin at 0, 2.2, and 4.4 mg/kg. A factorial design with vomitoxin at 0 and 4.4 mg/kg and salinomycin at 0 and 22 mg/kg was used in Experiment 4. Poults fed the suspect commercial diet had significantly lower feed consumption and higher motality than poults fed a control diet (P less than .05). Poults (0 to 3 wk of age) fed diets containing vomitoxin (4.4 mg/kg), salinomycin (22 mg/kg), or both showed no significant decrease in feed consumption, body weight gain, or viability.
