Daftar Isi:
- The aim of this study was to determine the effect of the supplementation of dl-methionine and l-lysine HCl into feed based on cafeteria standards to intestinal morphology of native chickens at 20 weeks-old. A total of 128 fourteen week-old native chickens were used in this study. The native chickens were divided into 4 treatments groups with 4 replications. The dietary treatments were: T0 (feed based on cafeteria standard), T1 (feed based on protein standard of NRC), T2 (cafeteria feed+0.09% dl-methionine+0.22% l-lysine HCl), T3 (cafeteria feed+0.19% dl-methionine+0.42% l-lysine HCl). The data collected were villus height, crypt depth and villus width of duodenum, jejunum and ileum of native chickens aged 20 weeks. The result of this study for T0, T1, T2 and T3 showed that villus height of duodenum were 863.03; 1237.85; 1171.60 and 1261.15 μm, crypt depth 212.70; 192.08; 210.25 and 251.85 μm, villus width 168.74; 168.53; 213.61 and 188.60 μm. Villus height of jejunum were 1381.48; 1088.70; 1072.68 and 1383.15 μm, crypt depth 272.,05; 261.83; 225.00 and 205.65 μm, villus width 188.28; 166.41; 216.26 and 182.95 μm. villus height of ileum were 798.03; 863.35; 882.88 and 828.70 μm, crypt depth 199.58; 199.58; 154.68 and 145.78 μm and villus width 181.13; 154.55; 201.25 dan 175.65 μm, respectively. It can be concluded that supplementation of dl-methionine and l-lysine HCl was not effected upon villus height, crypt depth and villus width of duodenum, jejunum and ileum of native chickens aged 20 weeks.
- Penelitian ini bertujuan mengetahui morfologi usus ayam kampung umur 20 minggu yang disuplementasi dl-metionin dan l-lisin HCl pada pakan standar kafetaria. Sebanyak 128 ekor ayam kampung umur 14 minggu dibagi dalam 4 perlakuan dan 4 ulangan masing-masing 8 ekor. Perlakuan yang diberikan adalah T0 (pakan berdasarkan standar kafetaria); T1 (pakan dengan standar protein menurut NRC; T2 (pakan kafetaria dengan suplementasi dl-metionin 0,09% dan l-lisin HCl 0,19%); T3 (pakan kafetaria dengan penambahan metionin 0,19% dan lisin 0,42%). Parameter yang diamati adalah tinggi vili, kedalaman kripta dan lebar vili duodenum, jejunum dan ileum usus ayam kampung. Hasil penelitian mendapatkan bahwa rata-rata tinggi vili duodenum masing-masing untuk T0, T1, T2 dan T3 adalah 863,03; 1237,85; 1171,60 dan 1261,15 μm, kedalaman kripta 212,70; 192,08; 210,25 dan 251,85 μm, lebar vili 168,74; 168,53; 213,61 dan 188,60 μm. Pada jejunum, tinggi vili 1381,48; 1088,70; 1072,68 dan 1383,15 μm, kedalaman kripta 272,05; 261,83; 225,00 dan 205,65 μm, lebar vili 188,28; 166,41; 216,26 dan 182,95 μm. Ileum, tinggi vili 798,03; 863,35; 882,88 dan 828,70 μm, kedalaman kripta 199,58; 199,58; 154,68 dan 145,78 μm dan lebar vili 181,13; 154,55; 201,25 dan 175,65 μm. Dari penelitian ini dapat disimpulkan bahwa suplementasi dl-metionin dan l-lisin HCl dalam pakan tidak mempengaruhi ukuran morfologi usus ayam kampung umur 20 minggu.
