Extract

Rumen protozoa population is reduced when ruminant are feed with foliage from some tropical trees an effect attributed to both saponins (Diaz et al., 1992) and tannins (Odenyo et al., 1997a). As PEG binds to tannins, it has been used to reduce its deleterious effect in animals feed tanniferous trees (Makkar et al., 1998). In a companion summary (Monforte et al., 2005) we showed that using PEG the defaunating capacity of a tanniferous tree is reduced. The objective of the present study was to assess if adding PEG to a protozoa culture will help to separate the tannin and saponin effect upon the protozoa population.
