• Resumen

  • The aim of this work was to evaluate the effect of replacing 0, 50, 75 or 100% of cereals-based concentrate in diets based on alfalfa hay with feed blocks including barley grain or 650 g/kg fresh matter of greenhouse waste fruits (tomato or cucumber) on the in vitro ruminal fermentation, digestibility and methane production. Three incubation runs were carried out in batch cultures of mixed rumen microorganisms. Kinetics of gas production were valuated based on the model y = A [1 - e-c•t]. The type of feed-blocks did not show any effect (P 0.14). However, the level of concentrate replacement with blocks affected (P 0.023) the pH, CH4 concentration, degradation rate, total gas, CH4 and total VFA productions, acetate/propionate and CH4/Total VFAs ratios and molar proportions of acetate and butyrate. Results from this experiment indicate that increasing levels of concentrate replacement with feed blocks modified ruminal fermentation, DM and NDF digestibility and had an antimethanogenic effect.
