Penelitian ini bertujuan untuk menurunkan toksisitas AFB1 pada itik peking dengan penambahan metionin dalam pakan sehingga meningkatkan produksi glutathione (GSH) dan mencegah kerusakan hati, serta mengetahui pengaruhnya terhadap konsumsi pakan, pertambahan bobot badan, dan konversi pakan itik peking. Penelitian ini menggunakan rancangan acak lengkap (RAL) pola searah. Terdapat lima perlakuan, empat ulangan, dan masing-masing ulangan menggunakan lima ekor itik Peking (Anas platyrhynchos) betina umur 21 hari. Total itik yang digunakan yakni 100 ekor. Perlakuan terdiri atas: kontrol negatif (tanpa penambahan AFB1 dan metionin; P0), kontrol positif (penambahan 50 ppb AFB1; P1), P1 + 0,32% metionin (P2), P1 + 0,47% metionin (P3), dan P1 + 0,62% metionin (P4). Data penelitian dianalisis variansi dengan mengikuti RAL pola searah menggunakan software SPSS statistik versi 20. Perbedaan nyata antar pelakuan, dilakukan uji lanjut menggunakan uji DMRT. Hasil penelitian menunjukkan bahwa pemberian metionin sebanyak 0,47% (P3) dalam pakan mampu meningkatkan kadar GSH, tertinggi dibanding yang lainnya (P<0>

This research aims to reduce the toxicity of AFB1 in Peking ducks by adding methionine to feed thereby increasing glutathione (GSH) levels and preventing liver damage, as well as determining its effect on feed consumption, body weight gain and feed conversion in Peking ducks. This research used a unidirectional completely randomized design (CRD). There were five treatments, four replications, and each replication used five female Peking ducks (Anas platyrhynchos) aged 21 days. The total number of ducks used was 100 ducks. Treatments consisted of : negative control (without addition of AFB1 and methionine; P0), positive control (addition of 50 ppb AFB1; P1), P1 + 0.32% methionine (P2), P1 + 0.47% methionine (P3), and P1 + methionine 0.62% (P4). The research data was analyzed for variance by following CRD with a unidirectional pattern using SPSS statistical software version 20. The real differences between the treatments were further tested using the DMRT test. The results of the research showed that addition of 0.47% methionine (P3) in feed was able to increase GSH levels, the highest compared to the others (P<0 lang="IN" xss=removed>1,313/head/day compared to P1, P2, P3 and P4 feeds. Based on the research results, it can be concluded that addition of 0.47% methionine (P3) to Peking duck feed contaminated by AFB1 50 ppb/kg can increase GSH levels and protease enzyme activity which has an impact on feed consumption, body weight gain and feed conversion also there was no significant effect with the negative control treatment. However, the IOFC of the treatment feed with the addition of 0.32% methionine (P2) ranked highest compared to other treatment feeds.
