In vitro degradation of coast-cross (cynodon dactylon) by rumen microorganisms associated with Saccharomyces cerevisiae or humicola sp

Ruminal degradation of the dry matter and neural detergent figer of coast-cross (cynodon dactylon) forage, when previously inoculated with Saccharomyces cerevisiae or Humicolla sp., was estimated by in vitro incubation. The potential dry matter degradability was incresead in the presence of S. cerevisiae, whereas the incubation with Humicola sp. resulted in improvement of the neutral detergent fiber degradability. The rate of dry matter digestion was enhanced to above 15 per center with the inoculation with S. cerevisiae. The inoculation with S. cerevisiae or Humicola sp. increased the rate of digestion of the neutral detergent fiber in relation to the control treatment.
