Description
| - Cílem práce bylo posouzení vlivu pastvy ovcí na nutriční hodnotu porostů NPR Mohelenské hadcové stepi. Volná pastva s využitím elektrického ohradníku proběhla v letech 1997-98. Ovce plemene žírné merino přepásaly plochu 4,25 a 6 ha při pastevním zatížení 6,8--9,4 ovcí na 1 ha v roce 1997 a 6,7--8,7 ovcí na 1 ha v roce 1998. Pro odběry stepních porostů bylo vybráno pět stanovišť tak, aby jejich fytocenologické složení bylo typické pro určitou část stepi. Porosty byly odebírány v průběhu vegetačního období ve čtrnáctidenních intervalech z plochy 3x1 m2. V odebraných porostech bylo hodnoceno množství sušiny, vlákniny, dusíkatých látek, tuku, popela, bezdusíkatých látek výtažkových (BNLV), BE (brutto energie), ME (metabolizovatelné energie), NEL (netto energie laktace), NEV (netto energie výkrmu), PDIN a PDIE (PDI -- skutečně stravitelných dusíkatých látek v tenkém střevě přežvýkavců). V průběhu pastvy došlo ke snížení obsahu sušiny v porostech, ale i tak byl její průměrný obsah vysoký (35,45--46,78 %). V (cs)
- The aim of this research was to assess the implications of sheep grazing for the nutritional value of the vegetation in the Mohelno Serpentine Steppe National Nature Reserve (NNR). A free pasture controlled by an electric fence was practised from 1997 to 1998. The German Merino sheep were grazing on an area of 4.25 and 6 ha with a pasture load of 6.8 -- 9.4 sheep per 1 ha in 1997 and 6.7 -- 8.7 sheep per 1 ha in 1998. The steppe vegetation samples were collected from five different sites reflecting the phytocenological composition typical of the individual steppe areas. The vegetation samples were collected on an area of 3x1 m2 during the growing season at two-week intervals. The collected samples were tested for the amount of dry matter, fibre, nitrogenous substances, fat, ash, nitrogen-free extractive substances (NFES), gross energy (GE), metabolic energy (ME), lactation net energy (LNE), fattening net energy (FNE), PDIN and PDIE (PDI -- referring to the factually digestible nitrogenous substances i
