Abstract
Productive and digestive parameters (feed:gain conversion rates, whole-tract digestibility,
intestinal viscosity and kinetics of digesta ¯ow) were determined in broiler chickens fed on three
diets of different viscosities, maize (low viscous), wheat±barley (medium viscous) and maize±10 g/
kg carboxymethyl cellulose (maize±CMC, high viscous) based. The three diets were supplemented
with 0, 10 and 20 g/kg of sepiolite (EXAL1 UE-562), respectively, to examine how soluble nonstarch polysaccharides per se in¯uence nutrient digestion, and the extent to which sepiolite
supplementation (10 or 20 g/kg) could improve dietary OM digestibility and AME content. Broiler
chickens fed on maize and barley-wheat showed higher (p
