Effect of mushroom substrate on the feed quality from the permanent meadow

Fodder nutritive value of permanent grassland is dependent on the concentration of individual nutrients, the degree of digestibility and energy concentration. In a grassland study on the base crude fiber content and relevant conversion formulas, digestibility of dry matter and net energy concentration of the feed can be calculated, without the need for specialized equipment. The aim of the study was to determine the effect of mushroom substrate and farmyard manure supplemented NPK, on the digestibility and energy concentration in the sward of permanent meadows in three-year field experiment. In the study, overall digestibility and net energy concentration of feed derived from permanent grassland remained at a high level. Overall digestibility of yield dry matter of grass varies significantly, depending on the collected cuts and year of study, while the net energy concentration did not show differences under the influence of experimental factors studied. Mushroom substrate used in the experiment (alone and completed mineral NPK) caused no significant effect on the digestibility and net energy concentration of the tested feed with regard to both the farmyard manure used as standard and with NPK.
