Improved digestibility, intestinal function According to Alfred Blanch, the consistency of the study data reflects the proven mode of action of the B. subtilis strain in GalliPro, which works by increasing enzyme activity, while improving intestinal function. Previous studies have shown that the probiotic significantly increases ileal protein digesti- bility of feed (Figure 3). Using a proprietary in vitro tool known as reducing-sugar release (RSR) analysis, Chr. Hansen scien- tists have also demonstrated that, by breaking down fibre and making more sugars available to birds, GalliPro increases energy release from feed ingredients (Figures 4 and 5). “B. subtilis enhances carbohydrate, protein and lipid meta- bolism by producing digestive enzymes that birds don’t produce on their own. This results in increased availability of dietary energy and feed nutrients,” Mr Blanch explains. “In ad- dition, GalliPro has been shown to promote healthy microbial diversity in the gut, while reducing gut inflammation.

properties contribute to healthier intestinal function, which improves absorption of feed nutrients.”

Compared to control, birds in the GalliPro group gained more weight and demon- strated signifi- cantly lower feed conversion ratios, regard- less of basal diet composition.
