Wed, 31 Dec 2025 00:00:00 +0000

Probiotics play an essential role in regulating gut microbiota and increasing feed digestibility in poultry. This study aimed to screen and characterize cellulase-producing bacteria as poultry probiotic candidates. Among the five isolates tested, isolates I5 and BP had cellulase activity, as indicated by clear zones surrounding the colonies on carboxymethyl cellulose (CMC) agar plates. Isolate I5 was more tolerant to low pH and 0.3% bile salts than isolate BP, indicating probiotic potential. Isolate I5 was selected for cultivating in tempeh wastewater-molasses medium (TM) and LB medium at 37 °C with shaking at 120 rpm. The results demonstrated that bacterial growth in TM medium was significantly lower (p < 0.001) than in LB medium. Importantly, bacterial growth in TM medium reached an optical density (OD₆₀₀) of 0.415 after 6 hours of incubation, indicating its adaptability to tempeh wastewater-molasses medium. These findings suggest that the TM medium promotes bacterial growth and proliferation, supports probiotic and enzyme production for use in poultry feed supplementation, and reduces cultivation costs. Therefore, the use of agro-industrial waste provides a cost-effective alternative for cultivating cellulase-producing probiotics, thereby contributing to value-added waste management, sustainable poultry production, and circular bio-economy practices.

Kade Wahyu Saputri, Nur’aini — Wed, 31 Dec 2025 00:00:00 +0000

To extend their shelf life beyond the approximate 14 days they last at room temperature, fresh eggs are often processed into liquid eggs. Storage at 4°C with the addition of forest honey (Apis dorsata), which is rich in antibacterials, antioxidants, and sugars, has the potential to maintain quality and serve as a sugar substitute in food products. This study evaluated the sensory quality of liquid eggs with forest honey after cold storage. A total of 60 chicken eggs were stored at 4°C for 21 days. Sensory testing was conducted on 21-day-old liquid eggs that had been steamed for 30 minutes. Panelists assessed color, aroma, taste, and texture, and data were analyzed using ANOVA with a DMRT follow-up test at the 0.05 level. Results indicated that the addition of wild bee honey (Apis dorsata) to liquid eggs stored at 4°C significantly improved the sensory attributes of egg whites, including color, odor, texture, and taste, but showed no significant effect on the sensory properties of egg yolks. Overall, liquid eggs with forest honey were acceptable to panelists and have the potential to be developed as a value-added food ingredient

Effectiveness of Replacing Rice Bran with Palm Oil Processing Solid by-products (Solid) on the Performance of Kaur Cattle

Jarmuji, Arif Rahman Aziz — Wed, 31 Dec 2025 00:00:00 +0000

Sakura Block Plus is a feed supplement designed to enhance cattle performance, with rice bran accounting for 22% of its total ingredients. However, due to the increasing scarcity and rising prices of rice bran, palm oil processing solid by-products offer a potential alternative. This study aimed to assess the effect of Sakura Block Plus supplemented with solid at different levels as a substitute for rice bran on dry matter intake and body weight gain in Kaur cows fed a natural grass diet. A Latin Square Design (LSD) was employed, involving four treatments and four replications. The treatments consisted of wild grass plus a sakura block, with 5.5% (P1), 11% (P2), 16.5% (P3), and 22% (P4) of the solid as rice bran replacement. The results indicated that replacing rice bran with solid up to 22% did not significantly affect dry matter intake (P>0.05). Still, there was a trend toward increased body weight gain at the highest solid level. Dry matter intake averaged 7.22-7.96 kg/head/day (2.80-3.06% of body weight), while body weight gain ranged from 0.41-0.52 kg/head/day. These findings suggest that solid can replace up to 100% of rice bran in sakura block plus formulations without adversely affecting cattle performance.

Revolution or Disruption? Implications of Precision Livestock Farming (PLF) for Traditional Livestock Systems in Indonesia

Wed, 31 Dec 2025 00:00:00 +0000

Precision Livestock Farming (PLF) is a modern approach to livestock management that leverages sensors, the Internet of Things (IoT), and artificial intelligence to enhance efficiency, productivity, and animal welfare. In developed countries, PLF is regarded as a revolution in the livestock sector; however, in the context of traditional livestock farming in Indonesia, particularly among small-scale beef cattle farmers, its implementation poses a dilemma between opportunities for transformation and risks of disruption. This systematic review, conducted in accordance with the PRISMA framework, critically examines the implications of PLF for traditional farmers by synthesizing literature from Scopus, Web of Science, ScienceDirect, and Google Scholar (2010-2024). Through thematic analysis of 40 selected studies, we find that PLF offers substantial benefits, including improved feed efficiency, early disease detection, and enhanced animal welfare, but also faces significant barriers, such as high investment costs, limited infrastructure, low digital literacy, and risks of smallholder marginalization. By integrating evidence from both technological and socio-economic perspectives, this review provides a holistic analysis of PLF’s dual role as both a transformative tool and a potential disruptor in developing agricultural contexts. The findings underscore the necessity of context-sensitive adoption strategies, informed by incremental technology introduction, supportive policies, targeted subsidies, cooperative models, and capacity-building initiatives. This study contributes to the literature by offering a policy-relevant framework for aligning PLF with inclusive and sustainable livestock development in Indonesia and similar settings.

Wed, 31 Dec 2025 00:00:00 +0000

Estrus synchronization is one method to standardize the estrus cycle in thin-tailed sheep. The objective of this study was to evaluate estrus quality and the success of artificial insemination using PGF2α hormone combined with GnRH. Hormones were administered by intramuscular (IM) injection. Sixteen female thin-tailed sheep aged 2–3 years with body weights of 33–35 kg were used. Treatments were divided into four groups with four replications: P0 (PGF2α 1 ml + GnRH 0 ml), P1 (PGF2α 1 ml + GnRH 0.5 ml), P2 (PGF2α 1 ml + GnRH 1 ml), and P3 (PGF2α 1 ml + GnRH 1.5 ml). Estrus observation was conducted visually. Artificial insemination was performed using frozen semen, and pregnancy detection was carried out with the PregnaDrop test kit. Data were analyzed using descriptive statistics and the Kruskal–Wallis test. The results showed that the administration of GnRH and PGF2α significantly affected the success of artificial insemination, with estrus onset differing significantly (P<0.05) and estrus intensity differing highly significantly (P<0.05). The best dose was found in P3 (PGF2α 1 ml + GnRH 1.5 ml).
