Effect of Changes in Conserved Feed Composition in Diets on Fermentation Parameters and Fatty Acids Content in In Vitro Experiment
Popis výsledku v původním jazyce
The rumen simulating technique (RUSITEC) was used to evaluate the effect of 3 diets with different ratios of conserved feeds on rumen fermentation and the concentration of fatty acids (FA) in fermentation fluid. Diets included 30 % of alfalfa silage and70 % of corn silage (KD1), 30 % of alfalfa silage, 38 % of corn silage and 32 % of grain-legume silage (KD2) or 20 % of corn silage and 80 % of grain-legume silage (KD3), respectively, on dry matter basis (DM). We observed the lowest values of DM (P0.01)and crude protein (CP) degradability (P0.001) in diet KD3 and acid-detergent fiber (ADF) degradability in diet KD1 (P0.001). The degradability of neutral-detergent fiber (NDF) wasn´t influenced by composition of diets. The highest production of ammonianitrogen (NH3-N) (mg/l) in effluent was analysed in vesels with KD1 (P0.001), however the highest microbial activity in nitrogen synthesis was observed in vessels with KD3 (P0.001). Production of fermentation gasses, methane and volatile
