This study was conducted to determine the growth performance, carcass traits and lipid profile of broiler chicks fed with an exogenous emulsifier and increasing levels of energy provided by palm oil. A total of 640 one-day-old male Ross 308® broilers were placed for 42 days, and were assigned to four dietary treatments, with 8 replicates per treatment and 20 birds per replicate according to completely randomized design. The treatments consisted of three increasing levels of metabolizable energy (ME) of 12.13 MJ/kg (starter) and 12.80
