We evaluated the effects of different levels of DON (LD 441 and HD 1223 μg DON/kg in diet) on the growth performance, immunity, reproductive hormones, and intestinal health of immature gilts. No significant differences were observed in average daily gain, average daily feed intake, or feed to gain ratio between the LD group and the HD group (p > 0.05). The red blood cell count and hematocrit were higher in the LD group compared with the HD group on d 21 (p 0.05). For fecal microbiota, Streptococcus in the HD group was reduced compared with the LD group (p < 0.05). In summary, feeding diets contaminated with 1223 μg DON/kg exerted adverse effects on serum profiles of gilts but did not affect their growth performance or reproductive hormones in the present study.
