Influence of Hemicell® Addition on Diets Containing Different Levels of Crude Fiber on Performance of Laying Hens

This study was conducted to examine the effect of Hemicell ® addition on diets containing different levels of crude fiber on performance and egg quality of laying hens. A total of 72 laying hens aged 21 weeks were randomly divided into 18 experimental units. A completely randomized design with factorial design 2×3 and 3 replications was employed in this study. Factor A was crude fiber level (5% and 8%) and factor B was the level of Hemicell ® (0, 100x10 3 and 200x10 3 IU/kg ration).  Results showed that crude fiber significantly (P<0.01) increased feed consumption and decreased the performance of laying hens. The addition of Hemicell ® in diets significantly (P<0.01) decreased feed consumption and increased the performance of laying hens. Hemicell ® addition (100 IU) to a diet containing 8% crude fiber significantly (P<0.05) affected egg mass, feed conversion ratio, egg yolk score and egg weight. It can be concluded that diet with 8% crude fiber added with Hemicell ® (100 IU) could increase egg mass, feed conversion ratio, egg weight and yolk color score.
