Abstract

The aim of this experiment was the monitoring of the organic matter digestibility of 4 species of cereal forage during the growing season. The experiment was conducted in collaboration with cultivation station Slechtitelska Stanice Vetrov (Oseva UNI, a.s. Chocen). Analyses were performed in the laboratory of Faculty of Agriculture, University of South Bohemia in Ceske Budejovice. Organic matter digestibility was determined by pepsin-cellulase in vitro method according to Míka et al. (2009) with using inexpensive Czech cellulases in Ankom Daisy Incubator II. Statistical significant differences were found among cereal crops and sampling dates. Wheat forage had the highest organic matter digestibility and oat had the lowest. Cereals reported the highest organic matter digestibility in the first sampling date (13.06.14) and the lowest in the fourth sampling date (03.07.14). Organic matter digestibility of cereals was affected by vegetation stages. The highest organic matter digestibility was achieved before inflorescence emergence, the lowest during inflorescence emergence, heading, flowering, anthesis and development of fruit. Slight increase of organic matter digestibility was detected during the ripening. It was also found that the organic matter digestibility changed differently for each cereal plant during the season.
