Abstract

This study aims to determine the effect of substituting rice bran with fermented tofu pulp in the basal diet on the performance of grower phase broiler chickens in Mengeruda Village, Soa District, Ngada Regency. The study used a completely randomized design (CRD) with four treatments and three replicates, namely: P0 (100% basal diet without fermented tofu pulp), P1 (95% basal diet + 5% fermented tofu pulp), P2 (85% basal diet + 15% fermented tofu pulp), and P3 (75% basal diet + 25% fermented tofu pulp), each with three replicates. The population of chickens used in this study was 48, with each treatment consisting of 4 chickens and each treatment consisting of 3 replicates. Thus, 1 treatment required 12 broiler chickens. The research data were statistically analyzed according to RAL (Complete Randomized Design). If there were significant differences, they were followed up with a BNT test. The analysis was performed using SPSS 22.00 software. The parameters observed included feed consumption, weight gain, and feed conversion ratio (FCR). The results showed that the substitution of fermented tofu pulp had a significant effect on broiler chicken performance. Treatment P3 yielded the best results in terms of weight gain and feed conversion efficiency. This improvement in performance was due to better nutrient availability, increased digestibility, and a reduction in anti-nutritional factors.

Abstract

ABSTRAK Penelitian ini bertujuan untuk mengetahui pengaruh substitusi dedak padi dengan ampas tahu terfermentasi dalam ransum basal terhadap performans ternak ayam broiler fase grower di Desa Mengeruda, Kecamatan Soa, Kabupaten Ngada. Penelitian menggunakan Rancangan Acak Lengkap (RAL) dengan empat perlakuan, yaitu: P0 (100% ransum basal tanpa ampas tahu terfermentasi), P1 (95% ransum basal + 5% ampas tahu terfermentasi), P2 (85% ransum basal + 15% ampas tahu terfermentasi), dan P3 (75% ransum basal + 25% ampas tahu terfermentasi), masing-masing dengan tiga ulangan. Parameter yang diamati meliputi konsumsi ransum, pertambahan bobot badan, dan rasio konversi ransum (FCR). Hasil penelitian menunjukkan bahwa substitusi ampas tahu terfermentasi berpengaruh nyata terhadap performans ayam broiler. Perlakuan P3 memberikan hasil terbaik dalam hal pertambahan bobot badan dan efisiensi konversi pakan. Peningkatan performans ini disebabkan oleh ketersediaan nutrisi yang lebih baik, daya cerna yang meningkat, serta penurunan faktor anti-nutrisi akibat proses fermentasi. Dapat disimpulkan bahwa ampas tahu terfermentasi dapat digunakan sebagai bahan substitusi sebagian dedak padi dalam ransum basal ayam broiler tanpa menurunkan performans pertumbuhan, serta dapat menjadi alternatif pakan yang lebih ekonomis bagi peternak lokal.
