The use of BioMos and Bioplex Zn improved G:F in the starter period. Effects appear to be due to different modes of action.
BioMos decreased jejunal numbers of enterobacteria, and Bioplex Zn tended to increase the
weight of the ileum containing Peyer’s patches (P= 0.08).
Complementarity of both additives was manifested by a significant increase in villus:crypt ratio only when both additives were included in the feed.
