Abstract

The effect of ß-glucanase and xylanase supplementation of rye feed on the viscosity and microstructure of the chicken digesta was studied. The viscosity of the digesta decreased significantly in both anterior and posterior parts of the small intensine due to the enzyme supplementation. The fluorescence microscopic examinations indicated that the supplemented enzymes had effectively hydrolyzed the endosperm cell walls of the feed and made the digestion of the nutrients possible earlier in the anterior part of the small intensine. On the basis of these observations it can be concluded that the supplementation of rye feed with cell wall hydrolases seems to be a powerful tool in decreasing digesta viscosity and thus improving the availability of the nutrients for chickens.
