The Efficiency of Xylanase in Broiler Chickens Fed with Increasing Dietary Levels of Rye

摘要

Simple SummaryIn this study, the effect of xylanase addition to a diet with an increasing content of modern hybrid rye was evaluated. In the first feeding phase (from 1 to 21 days of age), even a low dietary level of rye (5%) decreased the body weight gain of birds. However, results obtained in older birds indicated that modern hybrid rye can be used in up to 20% dietary level in broiler diets from 22 to 42 days of age, especially when the diet is supplemented with xylanase.
