Effect of source and particle size of dietary fiber on performance and egg quality in commercial laying hens

Abstract:
This study was conducted to determine effect of sources and particle size of fiber on performance, egg quality and pH of excreta in laying hens. A total of 324 Lohmann LSL-lite laying hens was arranged in a factorial experiment with nine dietary treatments, each replicated six times. Experimental treatments consisted of two fiber sources (sunflower hulls, SFH and sugar beet pulp, SBP), two levels of fiber (2.5 and 5%), two fiber particle size (fine, 2 mm and coarse, 6 mm) with a control group. Results showed that main effects of sources, level and particle size of fibers did not significantly affect hen-day egg production, egg weight, egg mass, feed intake, feed conversion ratio and body weight gain. On week 30, inclusion of coarse SFH (5%) significantly reduced shell weight and shell thickness (P
