摘要： Two additives (bacterial inoculants and fibrolytic enzymes) were tested for their effects on fermentation characteristics, invitro digestibility, mold counts and aflatoxin (B-1, B-2, G(1) and G(2)) content in corn silages. Whole-plant corn was harvested with one-half milk line stage and ensiled after the following treatments: (i) untreated (CON); (ii) bacterial inoculants at 10(5) CFU g(-1) of fresh forage (B); (iii) fibrolytic enzymes at 100 U g(-1) of fresh forage (E); and (iv) mixture of bacterial inoculants and enzymes at 10(5) CFU g(-1) and 100 U g(-1) of fresh forage, respectively (B+E). All the additives increased the lactic acid content and invitro dry matter digestibility (P < 0.05), decreased ammonia nitrogen content (P < 0.05). E and B+E decreased the neutral detergent fiber content and increased the crude protein, invitro digestibility of neutral detergent fiber and crude protein (P < 0.05). Aflatoxins content and mold counts for treated silage were lower than untreated silage (P < 0.05) throughout the air exposure stages (0, 1, 5, and 10 days). Additionally, the aflatoxins were not detected in B treated silage after 0 day exposure to air and in B+E throughout the air exposure stages.
