• Resumen

  • The objective of this study was to investigate the effects of three enzymes (cellulase, xylanase and a 1:1 mixture of both enzymes), applied either immediately before incubation or 24 h before, on the in vitro gas production of three tropical forages. In general, xylanase showed little or no effects (P>0.05) on in vitro gas production for the three forages. Both cellulase and the mixture increased (P<0.05) the gas production rate and effective degradability of organic matter when they were applied to forages 24 h before incubation, but the effects were less marked or even disappeared when were applied immediately before incubation. Neutral detergent fiber content of two forages decreased (P<0.05) after 24 h pretreatment with cellulase. The results indicate that 24 h pre-treatment of forages with cellulase and the mixture increased their efficacy, but results were affected by the incubated forage.
