Popis: Summary In many regions, optimum dry matter (DM) content of corn crop preensilage cannot be ensured for management, agronomical and climatic reasons. Under such conditions, corn crops are harvested at low DM, and are easily exposed to unfavourable fermentation pathways and plant spoilage and wastage. Thus, it is a major question for dairy agriculturists whether certain microbial inoculants application to low-DM corn crop pre-ensilage affects silage quality and cow performance. The objective was to determine effects of adding microbial inoculants to low-DM corn crop at ensiling on silage quality, rumen fermentation and milk production of eight Holstein cows fed the treated silages. Whole corn plant was harvested at milk stage of maturity with 204 g DM/kg of fresh crop, cut to a theoretical particle length of 2 cm, filled in 60 t bunker silos, and treated layer by layer with either no inoculant (control), inoculant ‘E’
