Effect of water extract of Curcuma domestica and Hylocereus polyrhizus in drinking water on carcasses and blood lipid profile of broilers

This study aims to determine the effect of water extract of Curcuma domestica clove (CE) and Hylocereus polyrhizus peel (HC) through drinking water on carcasses and blood lipid profile of broilers. This study used 180 day-old-chicks (DOD) with homogeneous body weight randomized into 4 treatment groups and 5 replications.  Each repetition used 40 heads DOC with homogeneous body weight. The four treatment groups, namely: the group of chickens that were given drinking water without the addition of CE and HC extract as a control (P0); group of chickens given drinking water added with 4% CE (P1); group of chickens given drinking water added with 4% HC (P2); and the group of chickens that were given drinking water supplemented with 2% CE+2% HC (P3). The results showed that the inclusion of aqueous extracts of CE, HC and their combinations in drinking water from 1-35 days of age had no significant effect (P≥0.05) on carcass weight, carcass percentage and meat in broiler carcasses. However, blood cholesterol levels decreased significantly (P≤0.05) compared to the control group. It was concluded that supplementation of aqueous extracts of CE, HC, and their combinations in drinking water did not have a negative impact on broiler carcass characteristics.  However, it can significantly improve blood lipid profiles, namely reducing total cholesterol levels.
