Kaličinská, Martina
The aim of this thesis is to assess quality of grass vegetation used for prolongation of pasture period and to compare capacity ganges of organic nutrients from June till November. Next aim is to compare fodder quality of perennial ryegrass, intergenic hybrid Felina, and Meadow Fescue in the end of vegetation perion and assess utilization possibilities of grass vegetation for elongated, so called winter pasture in Czech republic. NL content by grass pasture in June is 12,2%, then gradually comes increase (P<0,05) up to 17,093% in October. NEL content is highest in June, August and September (5,99-6,257 MJ.kg-1). The content decreases (P<0,05) to 5,09 MJ.kg-1 In Jule, Octrober nad November. Roughage content is constat during research period. Metabolisable energy content during June, August and September is 10,17-10,5 MJ.kg-1. Lowest content - to 8,63 MJ.kg-1, was recorded in November. For pasture period prolongation is convenient festucoid hybrid (Festuca arundinacea x Lolium multiflorum), where the content of NL in October was 16,5%, roughage content 21,12% and NEL content 6,14 MJ.kg-1, metabolisable energy was 10,23 MJ.kg-1. We can consider the Pennerial Ryegrass and the Meadow Fescue as another suitable kind, because there were not recorded any significant differences (P<0,05).
