Název v původním jazyce

Effect of silage additives on fermentation characteristics of maize silage

Popis výsledku v původním jazyce

The aim of this study was to evaluate the effect of chemical and microbiological additives on fermentation characteristics in com silage at 1, 3, 5, 10 and 90 days of ensiling. The following additives were used: commercial bacterial inoculant (2 g/t) containing homofermentative lactic acid bacteria Lactobacillus plantarum, Lactobacillus paracasei and Pediococcus pentosaceus, and chemical additive containing formic acid, propionic acid, ammonium formate and benzoic acid (4 1/t). Both additives positively influenced the fermentation process in corn silage. Their application resulted in a decreased pH in the treated compared to untreated silage at 1 day of ensiling (P<0.05). Significant pH reductions (P<0.05) were particularly observed between days 1 and 3 and between days 3 and 10 for all treatments. The highest content of water soluble-carbohydrates (WSC) was preserved in the silage treated with the chemical additive (P<0.05) at 3, 5, 10 and 90 days of ensiling. The highest and thus the most desirable value of the lactic to acetic acid ratio was obtained at 90 days of ensiling in the group with the bacterial additive (P<0.05).
