This study aimed to isolate and identify bacteria from the rumen fluid of Bali cattle and to evaluate their effect as microbial inoculants on the in vitro digestibility of rice straw. The experiment was conducted using a Completely Randomized Design (CRD) consisting of four treatments and four replications. The treatments included rice straw silage with the addition of 0%, 5%, 10%, and 15% of local microorganisms (MOL) derived from cattle rumen fluid. The observed variables included the isolation and identification of bacteria from the rumen fluid, and the assessment of in vitro digestibility, including Dry Matter Digestibility (DMD), Organic Matter Digestibility (OMD), Volatile Fatty Acid (VFA) concentration, and ammonia (NH₃) production. The results showed that the addition of rumen fluid MOL significantly (P<0.05) improved the digestibility parameters. The highest DMD (52.44%) and OMD (47.11%) were obtained from the treatment with 15% MOL. VFA and NH₃ concentrations also increased, indicating enhanced microbial activity and fermentation efficiency. The study concludes that MOL derived from cattle rumen fluid, particularly those containing Bacillus sp., is effective in improving the nutritional quality and digestibility of rice straw

This study aimed to determine the effect of different levels of fish meal on the energy consumption of young male Kacang goats fed a complete silage diet. The study was conducted over three months in Kefamenanu Selatan Village, North Central Timor Regency (TTU), using nine 6–8-month-old Kacang goats with an initial weight of 11–14 kg. The goats were divided into three treatment groups, namely T1: 45% complete silage + 25% ground corn + 15% bran pollard + 10% rice bran + 5% fish meal; treatment T2: 45% complete silage + 25% ground corn + 10% pollard bran + 10% rice bran + 10% fish meal; treatment T3: 45% complete silage + 25% ground corn + 10% pollard bran + 5% rice bran + 15% fish meal. The variables observed included gross energy (GE), digestible energy (DE), faecal energy, urinary energy, metanae energy and metabolisable energy (ME). The results showed that gross energy (GE), digestible energy (DE), faecal energy, urinary energy, metanae energy and metabolisable energy (ME) of male Kacang goats fed different levels of fish meal did not differ significantly between treatments. It can be concluded that feeding 5%, 10%, and 15% fish meal levels to young male Kacang goats that received complete silage as their basic feed had no significant effect on gross energy consumption, digestible energy, faecal energy, urinary energy, or metabolic energy.

This study aimed to determine the effect of dietary turmeric (Curcuma longa) supplementation on the cholesterol profile of native chicken meat. Five treatments (control and four levels of turmeric inclusion) with five replications each were used. Data were analyzed using one-way ANOVA. The results showed that turmeric supplementation significantly affected meat cholesterol content (F = 16.302; p < 0.001). The highest cholesterol level was observed in the control group (67.06 ± 4.86 mg/100 g), while the lowest was in treatment 3 (41.57 ± 11.07 mg/100 g). Furthermore, crude protein and fat content of the meat also showed significant differences among treatments. These findings indicate that turmeric powder can be applied as a functional feed to produce native chicken meat with lower cholesterol content.

The purpose of this study is to assess the sensitivity of broiler chicken producers' income to fluctuations in live chicken selling prices and feed costs in Samarinda City. The research was conducted using a simulation approach under several scenarios of price and cost adjustments, ranging from - 20% to + 20% of the base value. The findings show that changes in selling prices had a more linear influence on income, with a 10% increase in live chicken prices increasing revenue by about 13%. Feed expenses, on the other hand, have a more unequal effect on revenue, particularly as costs grow, resulting in significant profit margin reduction. These findings imply that farmers' income is extremely vulnerable to external market dynamics, both in terms of income and production costs. This study validates earlier research findings published in international journals, emphasizing the necessity of risk mitigation methods and cost efficiency as critical variables for the long-term viability of small- and medium-sized poultry farming operations. As a result, governmental measures are required to safeguard farmers from volatility in both input and product prices.

Mastitis merupakan penyakit yang disebabkan oleh bakteri dan pada umum menyerang ternak perah. Berdasarkan hasil penelitian sebelumnya, terdapat perbedaan jenis bakteri penyebab mastitis di setiap daerah. Mengidentifikasi bakteri penyebab mastitis perlu dilakukan agar penyakit ini dapat ditangani dengan cepat, tepat, efektif dan efisien. Tujuan penelitian ini adalah untuk mengidentifikasi bakteri yang berpotensi menyebabkan mastitis di salah satu peternakan sapi perah di Yogyakarta. Pengujian California Mastitis Test dilakukan sebelum pengambilan sampel susu. Sampel susu yang menunjukkan hasil positif tiga kemudian diambil untuk diisolasi bakteri yang ada di dalamnya. Sampel susu yang berasal dari sapi yang terkena mastitis di peternakan tersebut diinolulasikan ke dalam bood agar, isolat yang tumbuh kemudian diinokulasikan kembali untuk selanjutnya dilakukan beberapa pengujian, seperti pewarnaan Gram, uji katalase, uji motilitas dan identifikasi menggunakan PCR. Hasil penelitian menunjukkan bahwa dua isolat dominan yang dihasilkan menunjukkan ciri – ciri berwarna ungu, berbentuk bulat, hasil uji katalase negatif dan hasil uji motilitas juga negatif. Hasil identifikasi menggunakan PCR menunjukkan bahwa kemungkinan spesies bakteri yang berhasil diisolasi adalah Streptococcus agalactiae, Bacillus cereus ,Bacillus thuringiensis, Bacillus wiedmannii, dan Endophytic bacterium. Streptococcus agalactiae dan Bacillus cereus merupakan bakteri dominan yang berhasil diisolasi dan kedua bakteri tersebut berpotensi sebagai penyebab mastitis pada peternakan di daerah Yogyakarta.
