However, the non-significant effect of OligoPKE supplementation on population of cecal pathogens (Figure 1), as previously mentioned was somewhat unexpected. Therefore, further investigation
is needed to confirm whether the lack of effect of OligoPKE supplementation on gut pathogens is due to
the insufficient amount of OligoPKE or other factors such as the presence of oligosaccharides of lower degree
of polymerization (Chen, et al. 2015).
