Abstract: to examine how different energy levels in the same protein affect feed intake, body weight gain, and feed conversion. The study used treatments in the form of differences in metabolizable energy levels at the same protein level, namely 19%. The feed treatments were as follows: T1 = 2800 kcal/kg, T2 = 2900 kcal/kg, T3 = 3000 kcal/kg, and T4 = 3100 kcal/kg. A total of 100 one-day-old unsexed broiler chickens were divided into four treatments, each of which was repeated five times. The feed treatment was administered from 1 to 35 days of age. The experimental design used a completely randomized design, followed by Duncan's test. The research parameters were feed intake, weight gain, and feed conversion. The results showed that increasing metabolic energy reduced feed intake and feed conversion (p<0.05) and increased weight gain (p<0.05). Feed intake was lowest at an energy level of 2900 kcal/kg, while weight gain was highest at an energy level of 3100 kcal/kg. Broiler performance was optimal at a protein level of 19% and a metabolizable energy level above 2900 kcal/kg.
