The panicles of Dragon oat variety were mowed during the growth season by the end of milk maturity - the beginning of wax maturity of the grain (cutting was made 5 cm below the panicle). The raw material was ensilaged in metal containers, according to three specifications (1 - crushed oat panicles without additive, 2 - uncrushed oat panicles without additive, 3 - uncrushed oat panicles + Microsil). The plants were crushed in a corn crusher (0.5 cm screens). Microbiological additive Microsil contained the strains of bacteria: Streptococcus faecium M 74, Lactobacillus platarum, Pediococcus spp. It was found that: the ensilages of uncrushed oat panicles with addition of microsil were characterized by a lower content of organic matter and nitrogen-free extraction compounds, while the content of crude fibre, crude protein and general digestible protein were higher than in ensilages without the addition, - the addition of microbiological preparation or the degree of crushing of the oat panicles was of no significant importance to the digestibility and energy value of the ensilages, - ensilaging of oat panicles allowed production of ensilages with lower content of crude fibre and higher energy value when compared with ensilages made of the whole cereal plants
