Abstract

Wolbachia is a naturally occurring bacterium found in various insects, such as fruit flies, butterflies, and moths. It has been utilized as an innovative strategy to control the spread of dengue fever by releasing Wolbachia-infected Aedes aegypti mosquitoes. This study aimed to assess the public’s understanding of the benefits of Wolbachia-carrying mosquitoes as a dengue control measure. Data were collected through questionnaire-based interviews with residents of Banjar Pande and Banjar Pasekan in Kaba-Kaba Village, Kediri District, Tabanan Regency. Pre-test results revealed that the level of knowledge among Banjar Pande residents was 50%, attitude 45%, and behavior 66%. Meanwhile, in Banjar Pasekan, pre-test scores for knowledge, attitude, and behavior were 47%, 47%, and 60%, respectively. These findings indicate that, prior to educational interventions, community awareness, attitudes, and behavior regarding Wolbachia mosquitoes as a dengue control strategy were at a moderate level. Post-test results demonstrated significant improvements, with the community exhibiting deeper knowledge, increased concern, and greater acceptance of Wolbachia technology. This study concludes that targeted education effectively enhances public awareness and support for Wolbachia as a sustainable dengue prevention approach.

Abstract

Layer poultry farming plays a vital role in ensuring food security by providing a safe, affordable, and high-quality source of animal protein through egg production. However, the industry faces significant challenges, particularly bacterial infections such as Escherichia coli and Salmonella sp., which can impact both poultry productivity and human health. This study aims to detect the presence of Escherichia coli and Salmonella sp. infections in the digestive tracts of deceased layer hens at poultry farms in Jatiluwih Village, Penebel Subdistrict, Tabanan Regency. The research employed an observational method with a descriptive approach, using swab samples taken from the small intestines of chickens that had died within 1–3 hours. Of the 100 samples analyzed, 63% tested positive for Escherichia coli, 2% for Salmonella sp., while 35% were suspected of being infected by other bacteria. These findings indicate a high prevalence of E. coli infection, which poses a potential threat to food safety and increases the risk of zoonotic transmission. Early detection and effective bacterial control measures are therefore essential to maintain farm sustainability and ensure the safety of egg products.

Abstract

Avian Influenza (AI) is a viral disease that poses a serious threat to poultry farming, particularly in broiler production. The rapid and massive spread of AI in poultry flocks can cause substantial economic losses for farmers. Vaccination is one of the primary strategies for AI prevention; however, the currently available AI vaccines are killed/inactivated types, which tend to induce antibody titers slowly. This limitation, coupled with the relatively short rearing period of broilers, reduces vaccine effectiveness in broiler chickens. This study aimed to evaluate the effect of green meniran (Phyllanthus niruri Linn.) extract on enhancing antibody titers in broilers when administered for two weeks prior to AI vaccination. A total of 30 broiler chickens aged from day 1 to 32 days were used as experimental subjects. The study employed a Completely Randomized Design (CRD) with three groups: negative control (K−), positive control (K+), and treatment group (P). Data were analyzed using Analysis of Variance (ANOVA) and Regression Analysis via SPSS software. The results demonstrated a comparative increase in average antibody titers in the treatment group receiving Phyllanthus niruri extract compared to the control groups. It was concluded that supplementation with Phyllanthus niruri extract effectively enhanced antibody titers in broilers vaccinated with the inactivated AI La Sota vaccine, with peak antibody responses observed 1–2 weeks post-vaccination. The administration of green Phyllanthus niruri extract has been proven to stimulate antibody titers in broilers by accelerating the development of protective antibody levels against the AI virus. The timing of sample collection was shown to significantly affect antibody titers, with the highest levels observed during the first to second week post-vaccination. Future research on the administration of Phyllanthus niruri extract to improve antibody titers against Avian Influenza (AI) in broilers is expected to extend the duration of supplementation until the harvesting period and to include higher dosage variations in order to achieve more optimal and protective results.

Abstract

Biosecurity is a fundamental protection system in poultry farming to prevent the entry and spread of diseases. This study evaluated biosecurity implementation and its role in mitigating disease risks in layer chicken farms in Babahan Village, Tabanan Regency, Bali. Using a descriptive quantitative approach, data were collected through closed-ended questionnaires and interviews with all 33 layer farmers in the village (total sampling) and analyzed via the Guttman scale. Results revealed that farmers' biosecurity knowledge was moderately adequate (66.08% affirmative responses). Implementation varied by measure: sanitation (68.5%) and traffic control (63.62%) were moderately practiced, while isolation protocols were poorly adopted (32.74%). Effective biosecurity correlated with reduced disease transmission and sustained productivity. Key influencing factors included farmers' knowledge, farm scale, infrastructure, government support, and operational habits. The study recommends enhanced biosecurity training, provision of isolation facilities and personal protective equipment (PPE), and targeted government support for small-scale farms to improve compliance.

Abstract

Pig farming in Indonesia has long been recognized by society and has become a well-established industry. The demand for pork products continues to show growth, but the increased risk of animal diseases remains a factor that could hinder production development in pig farming. The aim of this study is to determine the level of biosecurity implementation in pig farming in Melinggih Village, Payangan District, Gianyar Regency. In this study, a total sampling method was used, and data were collected through close-ended questionnaires via interviews with 20 pig farmers. The results were analyzed using descriptive quantitative analysis with the Guttman scale. The data obtained from the interviews were tabulated using Microsoft Excel, and the percentage of data in accordance with the assessments was calculated. Additionally, the data were analyzed using Spearman's rank correlation test to determine the relationship between knowledge, attitudes, and practices toward the implementation of biosecurity. The results show that the level of biosecurity implementation and the level of knowledge, attitudes, and practices of pig farmers toward biosecurity implementation in Melinggih Village, Payangan District, Gianyar Regency are as follows: isolation (67%), sanitation (74%), traffic control (58%), knowledge (43%), attitude (68%), and practice (74%). Meanwhile, the relationship between knowledge, attitude, and practice toward biosecurity implementation is unidirectional and has a significant correlation strength. Based on the results of this study, it is recommended that farmers further improve their knowledge of biosecurity and maintain or optimize the existing biosecurity implementation.

Abstract

Subclinical mastitis in sows (Sus scrofa) poses significant risks to pig health and breeding efficiency, particularly in Gianyar Regency, Bali. Early detection using the California Mastitis Test (CMT), followed by microbiological confirmation, is critical for effective management. This study aimed to evaluate subclinical mastitis in lactating sows using CMT and identify causative pathogens through laboratory tests. Milk samples from 30 lactating sows were analyzed. CMT-positive samples were cultured on selective media: Mannitol Salt Agar (MSA) for Staphylococcus aureus, Xylose Lysine Deoxycholate (XLD) for Salmonella, and Eosin Methylene Blue Agar (EMBA) for Escherichia coli. CMT detected subclinical mastitis in 21 sows (70%). Microbiological tests identified S. aureus (7 samples), Salmonella (2 samples), and E. coli (12 samples). CMT is an effective field tool for early mastitis detection. The high prevalence of pathogens, particularly E. coli, underscores the need for improved hygiene and targeted therapies in pig breeding environments.
