Abstract：To investigate the effects of Chinese herbal residues on the quality and safety of whole-plant corn silage，this study compared the effects of Eucommia ulmoides，Mentha spicata，and Codonopsis pilosula residues mixed with whole-plant corn（Zea mays） at fresh weight ratios of 5% ， 7% ，and 10% ，respectively，with thatof whole-plant corn silage alone.The impacts of these treatments on the quality ofcor silage and aflatoxin Bl content were assessed. The results showed that at 6O days of ensiling，except for the 10% Eucommia ulmoides and 5% Mentha spicata treatments， the water soluble carbohydrate（WSC） content of other treatments was significantly higher than that of the control P<0.05） .The 10% Codonopsis pilosula residue treatment had the highest WSC content. The acidic detergent fiber content in both the Mentha spicata residue treated groups and 10% Eucommia ulmoides residue treatment was significantly lower than that in the control （ P<0.05） ！ Additionally，the lactic acid content in both the 5% Mentha spicata residue and 5% Eucommia ulmoides residue treatments was higher than 100g⋅kg-1 DM and significantly higher than that of other treatments （ P<0.05） ！ Except for the 10% Codonopsis pilosula residue treatment，the aflatoxin B1 （AFBl） content of all treatments was lower than that of the control，and that of the 10% Eucommia ulmoides residue and 5% Mentha spicata residue treatments was significantly lower than other groups （ .After 9 days of aerobic exposure，the crude protein（CP）content inalltreatments decreased，but the CP loss rateof the Chinese herbal residue treatment groups was significantly lower than that of the control （P<0.05） ；the AFBl content of the 5% Mentha spicata residue treatment was the lowest，and significantly lower than that of other treatments （ .P<0.05⋅ .Considering the nutritional quality and safety of the whole-plant corn silage，mixing the whole-plant corn with either 5% Mentha spicata residue or 10% Eucommia ulmoides residue for ensiling is recommended.
