An experiment was conducted to study the influence of enzyme supplementation (ES) rye-based diets on rate food passage through digestive tract, viscosity jejunum content, volatile fatty acid concentration in ceca, and performance broilers. There were seven treatments; six arranged factorially with three varieties rye (Petkus, Prima, Saratov V) two levels ES (0 or 500 ppm an complex containing 858 IU beta-glucanase 864 xylanase/g) additional control diet based corn. Each treatment replicated times (12 chicks caged together), trial lasted 25 d. Rye feeding increased intestinal impaired bird at d (P < 0.001). Among greatest feed intake weight gain obtained Petkus variety, which also produced lowest viscosity. Enzyme addition reduced time needed recover 1% (0.78 vs. 0.98 h; P 0.05) 50% (4.2 6.5 0.01) marker feces mean retention gastrointestinal tract (17.1 18.8 0.05). Also, 0.001) improved intake, daily gain, conversion birds from 4 but did not modify ceca. We concluded that added decreased accelerated transit, improving productive
