The objective of the present study was to observe and compare properties of nine maize hybrids biomass in order to determine their suitability for animal feed production. Yields, structure of the dry matter of the investigated maize hybrids, as well as the yield of the digestible dry matter were determined in maize hybrids harvested in the full waxy maturity stage. The content of lignocellulosic fibres, their respective ratios and the in vitro dry matter digestibility of the whole maize plant as well as the neutral detergent fibre digestibility (NDFD) were established. The results indicated significant differences in dry matter in vitro digestibility of the whole plant among different hybrids in the most optimal harvest stage. The whole plant dry matter digestibility of the investigated maize hybrids ranged from 59.67 to 65.53%. Very significant positive correlation was determined between NDFD and in vitro dry matter digestibility of the whole maize plant (r=0.66). Biomass of the selected maize hybrids was rated as feed of high quality and can, therefore, be used for animal feed production in different ratios depending on animal species, category and dietary needs.
