Resumen:

The effect of equine fecal inocula on the in vitro gas,methane (CH4), and carbon dioxide (CO2) productionwas elucidated in the present study. Fecal inoculawere obtained fromfour Azteca horses (aged 5e8 years, 480 ± 20.1 kg). In vitro fermentation (up to 48 hours) was performed with substrate consisting of 50% (w/w) oat straw and 50% (w/w) of a commercial concentrate in the presence of a commercial Lactobacillus farciminis product (0e6 mg/g DMof substrate). Incorporation of L. farciminis resulted in increased levels of asymptotic gas (GP), CH4, and CO2 production (P < .05).

Descripción:

The lag time and the rate of GP were shown to be independent fromL. farciminis addition (linear, P>.05; quadric, P>.05). Furthermore, a slight reduction in fermentationpH (linear, P ¼ .029) and higher metabolizable energy values (P ¼ .001) were obtained with L. farciminis supplementation in a dose-dependent manner. No significant impact of L. farciminis on dry matter degradability values was estimated (P > .05). In vitro gas, CH4, and CO2 productionwere increased (linear, P .001) in the presence of L. farciminis from6 hours of incubation onward. In conclusion, addition of L. farciminis at a dosedependent manner (2e6 mg/g DM of diet) was observed to be persuasive in terms of attaining amicable hindgut fermentationbyimprovingfecalgas kinetics viz.gas,CH4, andCO2 productionwithout any side effect
