[In sacco and in vitro study of the diminution in bacterial level in forages and concentrated feeds during their passage through the abomasum].

Abstract

The detachment of adherent bacteria from feed particles in the abomasum of sheep was assessed by in sacco and in vitro trials using 15N labelled bacteria. This detachment was similar amongst the feed residues tested (40.5%). However, bacteria were found to stick stronger on small (less than 250 microns) than on large particles.
