Abstract

This study aimed to find the effect of partial replacement of commercial feed with phytase-fermented rice bran (PFRB) and turmeric flour (TF) on total cholesterol, triglycerides, low-density of lipoprotein cholesterol (LDL-c), and high-density lipoprotein cholesterol (HDL-c) contents in broiler meat. The experiment used a completely randomized design (CRD), in which 36 male broilers were randomly assigned into six treatments. Those treatments were: 100% commercial feed as the control (P1), 100% commercial feed + 2% turmeric flour (P2), 95% commercial feed + 5% PFRB + 2% turmeric flour (P3), 90% commercial feed + 10% PFRB + 2% turmeric flour (P4), 85% commercial feed + 15% PFRB + 2% turmeric flour (P5), and 80% commercial feed + 20% PFRB + 2% turmeric flour (P6). The results showed that broiler meat fed on the PFRB at all concentrations (P3, P4, P5, and P6) had significantly lower total cholesterol, LDL-c, and triglyceride, but higher HDL-c content than that of control (P1), p < 0.05. However, the inclusion doses of PFRB (5%, 10%, 15%, and 20%) appeared to have no significant effect on total cholesterol, triglyceride, LDL-c, and HDL-c content in broiler meat, p > 0.05. Furthermore, the supplementation of 2% turmeric flour gave no significant effect on all measured variables, P > 0.05. These results suggest that partial replacement of commercial feed with PFRB can be used to lower cholesterol, LDL-c, and triglyceride depositions while increasing HLD-c content in broiler meat, although further studies are still required to find the optimal concentration of PFRB inclusion in feed.
