Sun, 30 Mar 2025 00:00:00 +0700

This study aimed to assess the potential of ammonia-treated palm fronds as a substitute for conventional forage in animal feed through in vitro analysis. The materials used were palm fronds, elephant grass, fine bran, corn, coconut meal, and urea. This study employed a Completely Randomized Design (CRD) with five treatments and four replications. The treatments applied in this study were: T0: 70% forage (all grass, no ammoniated palm fronds) + 30% concentrate, T1: 70% forage (75% grass, 25% ammoniated palm fronds) + 30% concentrate, T2: 70% forage (equal portions of grass and ammoniated palm fronds) + 30% concentrate, T3: 70% forage (25% grass, 75% ammoniated palm fronds) + 30% concentrate, and T4: 70% forage (entirely ammoniated palm fronds, no grass) + 30% concentrate. The observed variables in this study encompassed pH, digestibility of dry matter, organic matter, and crude protein, as well as the digestibility of NDF, ADF, and hemicellulose. The data obtained in this experiment were analyzed using analysis of variance (ANOVA) according to the design used. The post hoc test used was Duncan's multiple range test. The experimental results indicated that the treatments did not significantly affect (P>0.05) pH after in vitro testing. However, they had a significant impact (P<0.05) on the digestibility of dry matter, organic matter, crude protein, NDF, ADF, and hemicellulose. Digestibility increased with the increasing percentage of ammoniated palm fronds in the diet. In conclusion, this research demonstrates that the ammoniation process can improve the quality of palm fronds, leading to increased digestibility of palm fronds in the diet. Ammoniated palm fronds can replace forage in cattle feed based on nutrient digestibility in vitro.

Extended-spectrum β-lactamase Producing Escherichia coli in Broiler Farms in Ciampea Bogor

Sun, 30 Mar 2025 00:00:00 +0700

Long-term use of antibiotics in broiler chicken farming causes the emergence of resistant bacteria and increases the potential for multidrug-resistant bacteria. This study aims to investigate the presence and characteristics of extended-spectrum β-lactamase (ESBL) producing Escherichia coli (E. coli) in broiler farms located in Ciampea, Bogor. A total of 90 samples were taken from three broiler chicken farms located in Ciampea, Bogor. Sampling was carried out by swabbing the cloaca of 1% of the population on each farm. Gram staining and IMVIC biochemical tests were performed on colonies suspected of being E. coli. Confirmation of ESBL-producing E. coli using a double disc diffusion test with MHA. The results showed that ESBL-producing E. coli was present in 28,9% of broiler chicken cloaca swab samples (26/90). Antibiotic resistance tests of ESBL-producing E. coli isolates showed resistance to four antibiotics, namely chloramphenicol, amoxicillin, ciprofloxacin, and ampicillin. In this test, 22 isolates showed multidrug-resistant

Development of Slow-Release Urea Additives Using Autoclaved Oil Palm Empty Fruit Bunches and Urea via Wet Granulation for Ruminants

Sun, 30 Mar 2025 00:00:00 +0700

This study developed slow-release urea (SRU) additives using autoclaved oil palm empty fruit bunches (OPEFB) and urea via wet granulation to improve nitrogen utilization in ruminants. OPEFB was autoclaved at 121°C and 1 atm pressure to create a stable matrix, which was then combined with urea in different proportions to form SRU. In the first phase, the physical and morphological properties of autoclaved and non-autoclaved OPEFB were analysed using Scanning Electron Microscopy (SEM) and Fourier Transform Infrared (FTIR) spectroscopy. Neutral detergent fibre (NDF) and acid detergent fibre (ADF) were measured, with hemicellulose calculated as the difference between NDF and ADF. In the second phase, SRU formulations included varying percentages of urea and autoclaved OPEFB: SRU 100 (100% urea), SRU 98 (2% OPEFB), SRU 96 (4% OPEFB), SRU 94 (6% OPEFB), SRU 92 (8% OPEFB), and SRU 90 (10% OPEFB). SEM and FTIR descriptively showed surface changes in OPEFB after autoclaving, including increased porosity. Autoclaving also descriptively reduced NDF, ADF, lignin, cellulose, and hemicellulose contents. In vitro rumen incubation revealed that the addition of autoclaved OPEFB in SRU reduced urea release and pH in the rumen at various time intervals: 3, 6, 9, and 24 hours. SRU with autoclaved OPEFB optimizes urea use and controls nitrogen release.

The provision of feeder sheep is a problem for farmers due to a high mortality rate among pre- and post-weaned lambs. Whey protein contains amino acids, glucose, and immunoglobulin which facilitate immunity enhancement and body weight gain. This study aimed to evaluate the effectiveness of supplementing whey protein wafer on the performance and profile of weaning sheep. A total of 12 ewe were randomly allotted to 3 treatments: P0 (non-supplemented feed); P1 (1.5% whey protein wafer supplement; and P2 (3% whey protein wafer supplement). Each treatment was replicated four times. The results showed that the whey protein wafer supplement treatment significantly (P<0.05) affected erythrocytes, leukocytes, monocytes, glucose, and cholesterol. Wafer with 3% whey protein supplement showed the best average daily gain, a normal range of blood profile, and a good performance compared to other treatments. The normal blood profiles reflect the sound health of the sheep.

Effect of Thermomechanical Fermented Soybean Meal on Javanese Super Chicken’s Performance, Protease, and Blood Metabolic

Sun, 30 Mar 2025 00:00:00 +0700

Soybean meal, feedstuff obtained from soy seed oil extraction, is a common feed ingredient for poultry despite containing antinutritional factors (ANFs), which can alter digestive activity and decrease poultry productivity. ANFs are reportedly eliminable by fermentation protocol. This study identified the effect of thermomechanical Fermented Soybean Meal (FSBM) on Javanese Super Chicken’s protease activity, blood metabolism, and growth performance. A total of 90-day-old chicks (DOCs) of Indonesian male Javanese Super Chicken were allotted to three treatment groups: CON (non-FSBM); T1 (FSBM with Bacillus subtilis); T2 (FSBM with Aspergillus niger). All groups were replicated six times with five birds each. The study was conducted for 76 days, and all birds were healthy and vaccinated with Newcastle Diseases (ND), Lasota, and Gumboro A. The result indicated that thermomechanical FSBM affected significantly (P<0.05) daily feed intake, average daily gain, feed conversion ratio, total protein, total albumin, and globulin. Protease activity was not affected by the treatments.

This study explores the personality types of sheep farmers in Banjarnegara Regency and the influencing factors to their personality. Utilizing a quantitative approach with survey design, we collected data from 100 sheep farmers across various agroecological zones in the regency. The analysis revealed that the majority of sheep farmers were middle-aged (48.7 years on average) and extroverted (59%). Extroverted farmers tend to be younger, more open to innovation, and having higher education levels than their introverted counterparts. Logistic regression analysis identified age and education as significant factors influencing personality types (p<0.05), with older farmers were more likely introverted while extroverted farmers were associated with higher education levels. The findings suggest that personality traits drive sheep farmers in their farming practices, decision-making, and adaptability to change. This study has underscored the importance of tailored training programs and educational opportunities to enhance the productivity and welfare of sheep farmers in Banjarnegara. Future research should delve deeper into the interplay between personality types and other socio-economic factors to develop more effective empowerment strategies for livestock farmers.

This study seeks to comprehensively assess the impact of Rumen Protected Choline (RPC) supplementation on key parameters in dairy cows, including dry matter intake, milk yield, milk fat and protein composition, first estrus, open days, and Service per Conception (S/C). This research utilizes a quantitative meta-analysis methodology to systematically evaluate and synthesize data. The treatment used is supplementation Rumen Protected Choline and the basal diet for control. Observed parameters include dry matter intake (DMI), milk yield (MY), milk fat content (MFC), milk protein content (MPC), service per conception (S/C), first estrus (FE), and open days (OD). The study went through five stages, namely database preparation, meta-analysis implementation, heterogeneity testing, summary effect testing, and publication bias measurement. Tools used include PDF software for filtering journals and data processing applications such as Microsoft Excel, OpenMEE Software, and Review Manager 5.4 for data interpretation. Based on the results of the meta-analysis, it is found that RPC supplementation significantly affects (p<0.05) the increase in milk production, milk protein content, and milk fat content. It is also capable of reducing S/C and open days, but it does not affect dry matter intake and first estrus. The findings of this study, derived from a meta-analysis, indicate that while RPC supplementation has no impact on feed intake, it significantly influences reproductive parameters.
