| Summary: | An experiment was conducted to evaluate the effect of using graded levels of roasted sesame hulls (RSH) on growth performance and meat quality characteristics in broiler chickens. A total of 360 day-old Lohmann chicks were randomly allocated into 24 floor pens and raised over 42 days. One of four dietary treatments was assigned to each group of six pens in a completely randomized fashion. The chicks in the control group were fed a corn-soybean based diet (RSH-0), while the chicks in treatments two, three, and four were fed graded levels of RSH at 4% (RSH-4), 8% (RSH-8), and 12% (RSH-12), respectively. Diets were formulated to meet broiler chicks’ requirements according to the National Research Council for both starter and finisher rations. The results showed that RSH inclusion increased (P<0.05) feed intake and final body weight without adversely affecting the feed conversion ratio. Broiler chicks fed RSH-12 had heavier (P<0.05) breast and leg cuts compared to the control-fed group with no change to their chemical composition. Water holding capacity (WHC), cooking loss (CL), and shear force (SF) reported similar results in all dietary groups. The chemical composition of both thigh and breast cuts was not affected by the RSH. After one day of thawing, colour coordinates of breast cuts behaved similarly in all dietary groups. The results of this study suggest that the addition of RSH to broiler diets up to 12% improves their growth performance; nevertheless, carcass characteristics and meat quality showed no alterations compared to the control-fed group. |
