Extract

The in vitro gas production is a widely used technique for the evaluation of feeds for ruminant animals. Although it measures rate and extension of gas production during feed fermentation in culture medium, rumen inoculum from operated animals (fistulae) is required. Faecal microorganisms function similarly to those in the rumen; they decompose feed and do not require operated animals. The objective of the present experiment was to compare rumen liquor and equine faeces as source of inoculum in the gas production technique.
