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.
Penelitian ini bertujuan untuk mengetahui penampilan produksi ayam broiler yang diberi campuran ekstrak herbal yang telah difermentasi dalam air minum selama pemeliharaan. Penelitian dilaksanakan ...selama 35 hari di Laboratorium Kandang Percobaan Program Studi Peternakan Jurusan Teknologi dan Industri Peternakan, Fakultas Pertanian Universitas Sriwijaya. Penelitian ini menggunakan 100 ekor ayam broiler yang ditempatkan dalam kandang postal ukuran 70x70x70 cm. Ayam broiler diberi pakan starter (BR1) sampai umur 21 hari, selanjutnya diberi pakan finisher (BR2) sampai umur 35 hari. Penelitian dilaksanakan secara eksperimental menggunakan Rancangan Acak Lengkap yang terdiri dari 4 perlakuan dan 5 ulangan. Perlakuan merupakan penambahan ekstrak herbal fermentasi dalam air minum ayam broiler dengan dosis P0 (0 ml/liter), P1 (7,5 ml/liter), P2 (10 ml/ liter) dan P4 (12,5 ml/liter). Peubah yang diamati yaitu konsumsi ransum, konsumsi air minum, pertambahan bobot badan dan konversi ransum. Data dianalisa dengan analisis ragam (ANOVA) dan jika perlakuan berpengaruh nyata, maka dilakukan uji lanjut dengan Duncan’t Multiple Range Test (DMRT). Hasil penelitian ini menunjukkan bahwa penambahan ekstrak herbal fermentasi dalam air minum tidak berpengaruh nyata (P>0,05) terhadap konsumsi ransum dan konsumsi air minum, tetapi berpengaruh nyata (P<0,05) terhadap pertambahan bobot badan dan konversi ransum ayam broiler. Kesimpulan penelitian ini bahwa penambahan ekstrak herbal fermentasi dalam air minum sampai konsentrasi 12,5 ml/liter tidak mempengaruhi konsumsi ransum dan konsumsi air minum, tetapi dapat meningkatkan pertambahan bobot badan dan menurunkan angka konversi ransum ayam broiler. Konsentrasi penambahan ekstrak herbal fermentasi yang optimum adalah pada level 10 ml/liter dalam air minum, yaitu diperoleh konsumsi ransum sebesar 80,16 g/ekor/hari, konsumsi air minum 205,81 ml/ekor/hari, pertambahan bobot badan 65,79 g/ekor/hari dan konversi ransum sebesar 1,23.
This study aims to determine the best combination of pineapple waste liquid fermentation and Indigofera zollingeriana leaves, which produces the highest amount of lactic acid bacteria, the highest ...vitamin C content, and total phenols, and the best antioxidant from the combination of the fermentation results. The resulting fermentation product will be used as a natural feed additive in poultry rations. This research was conducted with an experimental method using a Completely Randomized Design (CRD), which consisted of five preparations and four replications. The treatments were combination of pineapple waste and Indigofera zollingeriana leaves: P1 (100% pineapple waste), P2 (98% pineapple waste and 2% Indigofera zollingeriana leaves), P3 (96% pineapple waste and 4% Indigofera zollingeriana leaves), P4 (94% pineapple waste and 6% Indigofera zollingeriana leaves) and P5 (92% pineapple waste and 8% Indigofera zollingeriana leaves). Substrate from each combination of pineapple waste and leaves of Indigofera zollingeriana was fermented with the contribution of 10% of lactic acid bacteria obtained from commercial yogurt and incubated for 72 hours. The parameters in this study consisted of total lactic acid (Lactobacillus bulgarius), the concentration of vitamin C, total phenols, and antioxidant activity. The results showed that the combination of pineapple waste and Indigofera zollingeriana leaves proved significantly (P <0.05) to total lactic acid bacteria (Lactobacillus bulgarius), vitamin C concentration, total phenols and antioxidant activity of the fermented liquid (supernatant) products. In conclusion, the combination of 92% pineapple waste and 8% leaves of Indigofera zollingeriana had the highest total bacterial contribution, produced the highest vitamin C and phenolic compounds, and increased antioxidants.

The quality of broiler chicken carcasses is greatly influenced by feed management and the number of nutrients digested in the digestive tract that will be utilized for optimal meat production. The ...study aimed to determine the effect of feeding fermented feed at different times on the production performance and quality of broiler chicken carcasses. The number of day-old chicks used in this study was 180 broiler chickens strain Cobb. This study was carried out experimentally using a complete randomized design consisting of four treatments and five replications. Each treatment carried out in this experiment consisted of a different length of time, namely feeding for 2, 3, 4, and 5 weeks. Experimental parameters included feed consumption, weight gain, and ration conversion. In addition, the carcass quality was investigated as live weight, carcass percentage, and percentage of broiler chicken abdominal fat. The results showed that the longer the time of fermentation feed significantly increased feed consumption by 40.07% and increased 13.77% weight gain, as well as decreased ration conversion by 25.33%. Furthermore, the same results were also obtained regarding live weight by 17.80% and increased percentage of the carcass by 8.84%, while the percentage of abdominal fat decreased by 12.90%. It can be concluded that the provision of fermented feed for 5 weeks can improve the production performance and carcass quality of broiler chickens.

Budidaya ternak itik di Desa Arisan Musi Timur, Kecamatan Muara Belida, Kabupaten Muara Enim terkendala dalam pemberian vaksin selama pemeliharaan ternak itik tersebut, hal ini disebabkan karena ...jumlah pemeliharaan ternak itik yang tidak seragam umur pemeliharaannya. Pemeliharaan yang tidak seragam menyebabkan tidak efisien dalam pelaksanan vaksin. Pemeliharaan ternak itik dilakukan secara tradisional dan skala kecil, sehingga tidak memungkinkan dilakukan vaksinasi karena ampul vaksin hanya tersedia dalam dosis yang besar (1 ampul vaksin memiliki 1000 dosis). Kondisi ternak itik yang tidak divaksin menyebakan sistem imun menjadi lemah. Pemberian herbal dapat dilakukan untuk memperbaiki metabolisme dan system imun ternak itik. Kelompok ternak itik yang diberikan herbal dalam pakannya memiliki tingkat morbiditas atau tingkat keparahan terhadap penyakit yang rendah, tingkat kematian hanya 1% dan tingkat penambahan popululasi yang lebih tinggi yaitu 30%, serta persentase penetasan yang tinggi yaitu 83-87%.
