Abstract

This study aimed to analyze the effect of substituting fish meal with chicken head meal on production performance, meat lipid profile, and economic efficiency of the kampung unggul balitbangtan chicken, as well as to determine the optimal substitution level. The study employed an experimental method using a completely randomized design consisting of five treatments and four replicates with varying levels of chicken head meal substitution. The treatments applied were: A0 = base diet, A1 = base diet + 15% fish meal, A2 = base diet + 10% fish meal + 5% chicken head meal, A3 = base diet + 5% fish meal + 10% chicken head meal, and A4 = base diet + 15% chicken head meal. The observed parameters included feed intake, body weight gain, feed conversion ratio, meat fat and cholesterol content, as well as economic analysis using the income over feed cost approach. The results showed that treatments A1, A2, A3, and A4 had a highly significant effect (P<0.01) on increasing feed intake compared to A0, with feed intake values of (A0 = 751.95 g/bird, A1 = 1,319.7 g/bird, A2 = 1,315.9 g/bird, A3 = 1,315.6 g/bird, A4 = 1,310.2 g/bird). The body weight gain of KUB chickens in treatments A1, A2, A3, and A4 showed a highly significant effect (P < 0.01) compared to the control group, with body weight gain values of (A0 = 116.5, A1 = 428.95, A2 = 412.1, A3 = 4019.1, A4 = 355.1). The feed conversion ratio of KUB chickens in treatments A1, A2, A3, and A4 showed a highly significant effect (P < 0.01) compared to the control, with conversion ratios of (A0 = 6.51, A1 = 3.08, A2 = 3.18, A3 = 3.23, and A4 = 3.72). However, the treatments had no significant effect (P > 0.05) on fat content, but had a significant effect (P < 0.05) on the cholesterol content of KUB chicken meat, with respective IOFC values (A0 = Rp 21,572, A1 = Rp 48,721, A2 = Rp 48,504, A3 = Rp 48,733, and A4 = Rp 45,493). Thus, it can be concluded that substituting fish meal with chicken head meal can improve production performance and IOFC values and affect meat cholesterol levels without altering the fat content of KUB chicken meat; however, the use of chicken head meal at high levels without fish meal tends to reduce production performance and IOFC values.
