This study investigates the long-term effects of deoxynivalenol (DON) consumption on avian growth performance, on the proliferation, apoptosis, and DNA damage of spleen cells, and Other Computer Adaptors on intestinal integrity.Two hundred and eight 5-day-old black-feathered Taiwan country chickens were fed diets containing 0, 2, 5, and 10 mg/kg of DON for 16 weeks.Body weight gain of male birds in the 2 mg/kg group was significantly lower than that in the 5 mg/kg group.

At the end of trial, feeding DON-contaminated diets of 5 mg/kg resulted in heavier spleens.Moreover, the increase in DON induced cellular proliferation, apoptosis, and DNA damage signals Therapeutic Gloves in the spleen, the exception being female birds fed 10 mg/kg of DON showing reduced proliferation.Expression of claudin-5 was increased in jejunum of female birds fed 2 and 5 mg/kg of DON, whereas decreased expression levels were found in male birds.

In conclusion, our results verified that DON may cause a disturbance to the immune system and alter the intestinal barrier in Taiwan country chickens, and may also lead to discrepancies in growth performances in a dose- and sex-dependent manner.
