The effect of various antifungal additives on fermentation and aerobic stability of soya milk or tofu residue silage. Animal Nutrition and Feed Technology, 22: 123–132. To investigate the effect of various additives on the fermentation products and aerobic stability of soya milk or tofu residue silage. Two mixtures were formulated with soya milk or tofu residue, molasses, spray corn husk, rice husk and corn germ meal in a ratio of 45:1:25:17:12, and they were ensiled in plastic pouches for 10 and 20 days. The mixtures were treated with or without microbial inoculation (Lactobacillus plantarum, Lactobacillus buchneri or combined; 106 cfu/g) using chemical additives (20% sodium benzoate, 10% potassium sorbate and 5% sodium nitrite; 2 or 4 L/tonne). The microbial inoculation had no effect on the final pH, the concentration of acid and ethanol in treated soya milk residue silage when compared with untreated silages. Silage treated with chemical additives had lower concentration of lactic acid, ethanol and acetic acid. The aerobic stabilities of silages treated with chemical additives were greatest among all treatments. In tofu residue silage, microbial inoculants increased the concentration of lactic acid as compared with other treatments. Microbial and chemical additives lowered the concentration of ethanol as compared with untreated silage. Silages treated with chemical additives remained stable for >7d. Silages treated with microbial inoculation and untreated silages were deteriorated within 5 days. Chemical additive inhibited the deterioration in 10- and 20-days ensiled soybean products residue silages.
