Palupi R, Abdullah L, Astuti DA, Sumiati. 2014.. Potential and utilization of Indigofera sp. shoot leaf meal as soybean meal substitution in laying hen diets. JITV 19(3):210-219. DOI: http://dx.doi.org/10.14334/jitv.v19i3.1084The objective of this study was to determine the potential of Indigofera sp. shoot leaf meal to substitute soybean meal in poultry diet. One hundred and sixty laying hens of Isa Brown strain, at 30 weeks old were used in this study and kept in individual cages. A Randomized Completely Design was applied with four treatments and four replications. The treatments were four levels of soybean meal protein substitution by Indigofera sp shoot meal protein in the diets: The level were 0% (R0), 15% (R1), 30% (R2) and 45% (R3). Eggs were collected daily and were evaluated on: weight, shell, albumen, yolk, intensity of yolk and haugh unit. Results showed that the nutrients content of Indigofera sp shoot leaf meal were crude protein 28.98%, crude fat 3.30%, crude fiber 8.49%, calcium 0.52% and phosphorus content was 0.34%. Indigofera sp shoot leaf meal contained a complete amino acids. The vitamin A and ß-carotene were high, i.e 3828.79 IU/100g and 507.6 mg/kg, respectively. It is concluded that Indigofera sp shoot leaf meal is potential to be used as an alternative source of protein. Substitute 45% soybean meal protein with Indigofera sp shoot leaf meal in laying hen diets increase egg quality and increase intensity of yolk colour to 55.88%. Penelitian ini bertujuan untuk mengetahui potensi nutrien yang dimiliki tepung pucuk Indigofera sp. (TPI) dan memanfaatkannya sebagai bahan pakan substitusi protein bungkil kedelai dalam ransum ayam petelur. Penelitian ini menggunakan ayam petelur strain ISA Brown umur 30 minggu sebanyak 160 ekor yang ditempatkan pada kandang individu. Penelitian menggunakan Rancangan Acak Lengkap, terdiri dari 4 pelakuan dengan 4 ulangan. Perlakuan pada penelitian ini merupakan substitusi protein bungkil kedelai dengan protein TPI R0 = ransum kontrol, R1= substitusi 15% protein bungkil kedelai dengan TPI, R2 = substitusi 30% protein bungkil kedelai dengan TPI substitusi 45% protein bungkil kedelai dengan TPI. Telur dikumpulkan setiap hari untuk mendapatkan data berat telur, berat kerabang, berat putih telur, berat kuning telur, warna kuning telur dan haugh unit. Hasil evaluasi kandungan nutrien TPI adalah protein kasar 28,98%, lemak kasar 3,30 %, serat kasar 8,49%, kalsium 0,52% dan kandungan phospor 0,34%. TPI mengandung asam amino yang lengkap dan memiliki vitamin A serta ß-karoten yang tinggi, yaitu berturut-turut 3828,79 IU/100g dan 507,6 mg/kg. TPI berpotensi untuk dimanfaatkan sebagai bahan pakan sumber protein. Substitusi 45% protein bungkil kedelai dengan protein TPI dapat meningkatkan kualitas telur dan meningkatkan intensitas warna kuning telur yang mencapai 55,88%.Kata Kunci: Bungkil Kedelai, Kualitas Telur, Nutrien, Tepung Pucuk Indigofera sp.

This study aimed to evaluate protein quality of top leaf meal of Indigofera zollingerina based on its net protein utilization (NPU) as well as to evaluate its metabolizable energy. Fifty broiler chicks were used in determination of NPU while fifteen broiler strain Cobbs chickens aged 5 weeks were used for metabolizable energy measurement. This study used descriptive method in which data obtained were analyzed and compared to NPU and metabolizable energy of soybean meal. The results showed that top leaf meal of Indigofera zollingerina had NPU of 38.58-46.98, which is 70.14%-85-42% of that NPU value of soybean meal is 55. Its metabolizable energy was 2791.12 kcal/kg, 9.46% higher than that of soybean meal. As the NPU and metabolizable energy were close to those of soybean meal, top leaf meal of Indigofera zollingerina can be used to substitute protein from soybean meal in poultry feed.

Objective: The study aimed to determine the effect of using a combination of cassava tuber (Manihot esculenta) and Indigofera zollingeriana leaf flour as an energy source supplemented with citric acid in the ration on performance, carcass quality, digesta pH, viscosity, and the number of villi in the intestines of broilers. Materials and Methods: The research design was completely randomized with five treatments and five replications, each containing four broilers. The treatment was a substitution of corn in the ration with a combination of cassava tuber and I. zollingeriana leaf (CIF): without CIF, 5% CIF substitute for corn + 0.2% citric acid, 10% CIF substitute for corn + 0.2% citric acid, 15% CIF corn substitute + 0.2% citric acid, and CIF corn substitute + 0.2% citric acid. Each treatment ration was supplemented with 0.2% citric acid. The variables that were looked at were ration consumption, body weight gain, feed conversion, live weight, percentage of the carcass, percentage of abdomi¬nal fat, pH, viscosity, and the number of broiler villi. Results: This study showed that the combination of CIF flour supplemented with 0.2% citric acid had a significant effect (p < 0.05) on body weight gain, ration conversion, live weight, carcass percentage, and the number of villi in broiler intestines. But it did not have a significant effect (p > 0.05) on the amount of feed eaten, the amount of fat in the abdomen, the pH of the digesta, or the thickness of the broilers’ blood. Conclusions: The combination of CIF flour at a level of 10% supplemented with 0.2% citric acid can be used as an energy source to replace corn without having a bad effect on production performance, carcass quality, and small intestine characteristics of broilers.

Tujuan penelitian ini adalah untuk mengetahui pengaruh level penggunaan tepung kulit kayufermentasi dalam ransum puyuh terhadap performa pertumbuhan ternak puyuh sampai umur 8minggu. Materi penelitian menggunakan 100 ekor burung puyuh betina jenis Coturnix-coturnixjaponica umur 14 hari (2 minggu). Penelitian ini menggunakan Rancangan Acak Lengkap (RAL)yang terdiri 4 perlakuan dan 5 kali ulangan. Perlakuan merupakan level penggunaan tepung kulitubi kayu fermentasi dengan level 0% (R0), 10% (R1), 20% (R2), dan 30% (R3) dalam ransum.Peubah yang diamati pada penelitian ini adalah konsumsi ransum, konsumsi protein, konsumsilemak, pertambahan bobot badan dan konversi ransum. Data dianalisis menggunakan analisisragam, jika terdapat perbedaan yang nyata pada perlakuan terhadap peubah yang diamati, makadilanjutkan dengan Uji Jarak Berganda Duncan’s. Hasil penelitian menyimpulkan bahwapenggunaan tepung kulit ubi kayu fermentasi sampai level 10% mampu meningkatkan performapertumbuhan puyuh umur 1 – 8 minggu.Kata kunci : Performa, Pertumbuhan, Puyuh, Tepung kulit ubi kayu fermentasi.
