Název v původním jazyce

Effects of grass species on ruminal degradability of silages and prediction of dry matter effective degradability

Popis výsledku v původním jazyce

Forty samples of grass silages, made from the five most widely used grass species to ruminant nutrition (Dactyhs glomerata L., Phleum pratense L., Lolium perenne L., Festuca arundinacea L. and hybrid Feline) were tested in the present study. These grassspecies conserved by an ensiling process were compared among each other according to dry matter (DM) rumen degradability parameters (a = portion of DM solubilized at initiation of incubation: b = fraction of DM potentially degradable in the rumen, c = rate constant of disappearance of fraction b and EDDM = effective degradability of DM, estimated for each ingredient assuming the rumen solid outflow rates of 0.02 (EDDM2), 0.05 (EDDM5) and 0.08 (EDDM8) h(-1)). Based on the chemical composition of grass silages the regression equations for prediction of EDDM were evaluated. The influence of the ensiling process on dry matter degradability parameters was also assessed The best values of EDDM were determined for Lolium perenne (EDDM2 = 753.2
