Extract

Native herbaceous browses at Northeast of Brazil have a dry tolerance and have been used as animal feed. Some of those plants have anti nutritional compounds such as tannins that can interfere on their intake and digestibility. Polyethylene glycol (PEG) has been used in gas-based techniques for assessing anti nutritional factors in tanniniferous plants for ruminants. The objective of this work was to compare the tannin bioassay technique using the semi-automated (Reading Pressure Technique - RPT) and manual (syringe) gas production techniques to evaluate the tannin effect upon in vitro rumen fermentation, using PEG as an inhibitor of tannin effects.
