To evaluate the toxic effects of mycotoxin-contaminated corn (MC) on breeders and their progeny chicks, a total 480 50-wks-old Cobb broiler breeder hens were fed following dies: 1) corn-soybean meal diet (Control; containing 70.35% corn), 2) MC substituting for 50% in Control (LM), 3) LM plus 2 g/kg one mycotoxin sequestrant, Toxy-Nil Plus (TNP) (LMT2.0), 4) 100% (HM), 5) HM TN (HMT2.0), 6) 2.5 TNP (HMT2.5). The contained 69.25 μg aflatoxin B1 (AFB1)/kg, 4875 deoxynivalenol (DON)/kg, 2262 zearalenone (ZEN)/kg. At wk 4 after inclusion, all eggs laid used hatch, chicks same mycotoxin-untreated 14 days. Dietary inclusion decreased hatchability set increased embryo mortality during day 18-21.5. addition these aforementioned indices MC-included diets. Maternal treatment BW at age days BWG 1-14, whereas maternal did not affect indices. In parallel, concentrations serum IgA, IgG, lysozyme 14, but Overall, dietary treatments growth had trend to increase IgA IgG compared treatments. It was concluded that feeding relative high ratio contaminated with low level AFB1, DON, ZEN negatively affected reproductive performance alleviated effects.
