Abstract

Avian Influenza (AI) is a highly pathogenic contagious disease in poultry caused by influenza A virus, particularly the H5N1 subtype. This disease significantly affects poultry health and causes considerable economic losses in poultry farming. This case report describes a 25-day-old broiler chicken from Demulih Village, Bangli, Bali, which showed symptoms of anorexia, weakness, greenish diarrhea, and rapid death. Epidemiological analysis revealed a morbidity rate of 33.3%, mortality rate of 22.7%, and case fatality rate of 68.3%. Anatomical pathology examination showed multiorgan hemorrhages, while histopathology revealed non-suppurative inflammation with lymphocytic infiltration in the brain, lungs, heart, pancreas, and intestine. Virus isolation using embryonated chicken eggs, along with hemagglutination (HA) and hemagglutination inhibition (HI) tests, confirmed Avian Influenza H5N1 infection. In addition, fecal examination identified Eimeria spp. oocysts, indicating coccidiosis. These findings highlight that H5N1 infection can be aggravated by parasitic co-infections, leading to increased mortality. Preventive measures should include routine vaccination, strict biosecurity, and good husbandry management to reduce the risk of disease spread in the future.

Abstract

Eid al-Adha is closely associated with large-scale animal slaughter, making it essential to ensure the safety of meat and organs distributed to the community. The liver is one of the vital organs shared with consumers but is prone to abnormalities, particularly in older goats. This study aimed to determine the percentage of suitability of goat livers (Capra spp.) from older sacrificial animals through post-mortem examination in East Denpasar District in 2025. A descriptive observational design with a cross-sectional approach was employed. A total of 42 goat liver samples were collected from five villages using purposive sampling combined with cluster sampling. Post-mortem examinations were performed through inspection, palpation, and incision, assessing parameters of shape, color, consistency, and odor. The results revealed that 39 samples (92.8%) were normal and deemed suitable for consumption, while 3 samples (7.2%) exhibited abnormalities such as white spots and pale discoloration, making them conditionally consumable after the removal of unfit portions. No samples were completely rejected or required special heat treatment. In conclusion, most livers of older sacrificial goats in the study area still met the Safe, Healthy, Wholesome, and Halal standards. Post-mortem inspection proved to be an essential preventive measure to safeguard food safety from sacrificial animals. It is recommended that similar inspections be consistently implemented to prevent unsuitable organs from being distributed to the public.

Abstract

Chronic otitis externa is an inflammatory condition that can involve multiple pathogens such as bacteria and fungi, and may be associated with disorders of adjacent sensory systems, including the nose and eyes. This case report aims to describe the management of a case of chronic otitis externa accompanied by rhinitis and conjunctivitis in a six-year-old female Persian cat. Diagnostic methods include history taking, complete physical examination, and supporting examinations such as hematology, otoscopy, rapid testing for feline calicivirus and feline herpesvirus-1, as well as bacterial and fungal isolation and identification from ear, nasal, and ocular exudates. Results revealed infection involving Pseudomonas sp., Bacillus sp., and Candida sp. in the ears, and Staphylococcus sp. in the nose and eyes. Otitis therapy involved ear cleaning using Ilium Oticlean® and topical application of a combination of gentamicin, nystatin, and fluocinolone acetonide (Topigen®) administered at three drops q12h for 14 days. Rhinitis and conjunctivitis therapy included systemic antibiotic amoxicillin-clavulanic acid (ClaPet 250®) at 20 mg/kg BW q12h for 7 days, and anti-inflammatory methylprednisolone at 1 mg/kg BW q24h for 3 days. A positive therapeutic response for rhinitis was observed after 7 days of treatment, whereas conjunctivitis showed slower improvement and required additional therapy with Erlamycetin Plus® ophthalmic ointment 3.5 g, applied once q12h for 5 days. Treatment of chronic otitis externa showed significant improvement after 14 days. Therefore, management of otitis externa, rhinitis, and conjunctivitis requires a multimodal approach and comprehensive diagnosis to confirm the etiology and support appropriate therapy. Special attention to environmental hygiene and care practices is essential to prevent recurrence.

Abstract

Goats are a livestock commodity that provides animal protein, supports food security, and offers income opportunities because of their relatively short production cycle. Successful goat farming relies heavily on effective sanitation and hygiene practices, which are crucial for preventing disease transmission and maintaining optimal productivity in the herd. This study aimed to examine the relationship between farmers’ characteristics (age, education, and farming experience) and the level of biosecurity and hygiene implementation, as well as their impact on disease occurrence in goat farms in Palangka Raya City, Indonesia. The study was conducted in August 2025 and involved 10 goat farmers who were surveyed, interviewed, and observed in the field. Data were analyzed using a scoring system and chi-square test (χ²). The results indicated that age and farming experience had no significant effect (p>0.05) on biosecurity and hygiene practices. In contrast, education significantly influenced the implementation of isolation biosecurity, health management, and hygiene (p<0.05). Moreover, farms with higher biosecurity and hygiene levels showed significantly lower disease occurrence. These findings underscore the importance of education in promoting effective biosecurity and hygienic practices. Enhancing farmer knowledge through targeted training and extension programs is essential for reducing disease risks, improving livestock health, and supporting the sustainability of goat farming in Palangka Raya.

Abstract

The pig farming industry in Indonesia plays an important role in the economy and food security. However, infections caused by the Porcine Reproductive and Respiratory Syndrome Virus (PRRSV) and secondary infections by bacteria such as Staphylococcus sp. often threaten the health of pigs and farm productivity. This study aims to analyze PRRSV infections and secondary infections by Staphylococcus sp. in pigs through clinical, histopathological, and bacteriological approaches. The research method uses a qualitative approach, focusing on data collection in the form of signalments, anamnesis, epidemiological data, clinical signs, and laboratory examination of a sample taken from a pig farm in Gianyar, which was subsequently analyzed descriptively. The observed clinical findings in the case animal included diarrhea, malnutrition with BCS-1, stunted growth (dwarfism), anorexia, lethargy, dyspnea, paddling before death, and lesions at several body sites. Histopathological examination revealed hemorrhagic et necrotizing meningoencephalitis, tracheitis, myocarditis et edematous, hemorrhagic et necrotizing bronchopneumonia, hemorrhagic hepatitis, lymphoid depletion, hemorrhagic et necrotizing glomerulonephritis with glomerular atrophy, gastritis, enteritis with mucosal erosion, typhlitis and necrosis, and hemorrhagic colitis with mucosal erosion. Bacteriological examination identified Staphylococcus sp. pathogenic bacterium. Based on clinical analysis, anatomical pathology, histopathology, and bacteriology, the pig in question is suspected to be infected with the PRRSV with a secondary infection by Staphylococcus sp. pathogen. Animal health management practices, especially PRRSV vaccination and proper herd management, are critical to reduce the risk of secondary infections by bacteria like Staphylococcus sp. Further research, particularly molecular Polymerase Chain Reaction (PCR) testing, is required to confirm the diagnosis.

Abstract

Lumpy Skin Disease (LSD) is a emerging infectious disease in cattle caused by the Lumpy Skin Disease Virus (LSDV) from the Capripoxvirus genus. The LSD is a severe infectious disease that has significant clinical and economic impacts on the cattle industry worldwide, and has spread to most Asian countries, especially Southeast Asia. Clinical symptoms include fever, skin nodules (with diameter ranging 0.5–5 cm, emaciation, enlarged lymph nodes, and in some fatal cases, death. The disease is spread by various vectors, such as ticks, mosquitoes, and certain flies. This literature review aimed to summarize scientific knowledge about LSD and its impact on livestock reproduction and production performance. The method used is a systematic literature review of academic databases, such as PubMed, Google Scholar, ResearchGate). The LSD causes significant economic losses due to reduced milk production, skin damage, and weight loss. Reproductive impacts include estrus failure or disorders, repeat breeding, abortion, endometritis, and infertility in bulls. The LSDV virus can persist in the testes, and viral DNA has been found in semen, potentially spreading the disease through artificial insemination. In conclusion, LSD has significant economic impacts due to reduced reproductive and production performance in cattle, threatening the sustainability of livestock business. Enhancements in disease management are needed via improved vaccination strategies and regulated vector control.

Abstract

Beef cattle farming in Dompu Regency, West Nusa Tenggara, is conducted semi-extensively for various purposes, including breeding. This study aimed to identify the beef cattle breeding management practices used by smallholder farmers in Dompu Regency. Data were collected through field observations and interviews using questionnaires administered to 133 farmers in two villages: Dorebara and Adu. The research variables included farmer characteristics, reproductive issues, preferred cattle breeds, breeding management, feeding practices, and livestock health control. The results showed that most farmers were of productive age, had completed secondary education, and operated their farms as a side business driven by economic and socio-religious motivations. The main challenges in semi-extensive beef cattle breeding were limited access to bulls, long calving intervals, and low body condition scores in cows. Farmers preferred Bali cattle and crossbred cattle, and continued to rely on natural mating because it is accessible and cost-effective. The use of legumes such as Leucaena leucocephala during pregnancy and lactation remains suboptimal, as knowledge of feed management is largely based on tradition. Livestock health programs have been supported by the government through annual vaccination campaigns, but farmers’ awareness of livestock health remains low. Beef cattle productivity in semi-extensive systems can be improved through technical assistance, extension services, and better access to superior bulls and high-quality forage.

Abstract

The success of artificial insemination in livestock depends on the quality and quantity of semen used in order to maintain a quality of semen itself. Hence, an effort to minimize the declining of spermatozoa quality during preservation is made by diluting semen using a diluent that contains nutrients in the right proportion between the diluent and semen.This study aims to determine the effect of adding an ethanol extract obtained from purple sweet potato to a coconut water egg yolk-based diluent on the quality of Landrace pig semen. This research was carried out based on an experimental laboratory study with a Completely Randomized Design (CRD) using a selected Landrace pig semen, which was taken from a pig. The research was also conducted in order to observe variables which included motility, viability, abnormalities, intact plasma membranes, and intact acrosomal membranes. The research used four specific treatments such as: P0 (BTS® as control), P1 (coconut water), P2 (coconut water and egg yolk), and P3 (coconut water, egg yolk + purple sweet potato ethanol extract), with six replications for each treatment. The data were analyzed using analysis of variance (ANOVA). If significant differences were found (p<0.05), statistical testing was performed using Duncan's test. The results of analysis showed that the P3 treatment group had the highest values ​​(p<0.05) for motility and viability, at 47.16±0.40% and 58.83±0.40%, respectively, compared to the other treatment groups. The P3 treatment group showed the lowest value for abnormality at 6.00±0.00%, contributing to a decrease of abnormality in a sperm. Furthermore, observations of intact plasma membranes and intact acrosomal membranes also showed that the P3 treatment group had the highest percentages, at 59.33±0.51% and60.16±0.98%, compared to the other treatment groups. The results of this study indicate that the combination of three components in the P3 treatment provides optimal protection for sperm cell structure, particularly in terms of motility, viability, abnormalities, as well as integrity of intact plasma membranes and intact acrosomal membranes. The electrolyte content in coconut water, phospholipids in egg yolk, and anthocyanins from purple sweet potato extract are thought to work synergistically to stabilize cell membranes and reduce free radical damage. Therefore, the results of this study recommend the use of local natural materials as a functional alternative diluent in pig reproductive technology.

Abstract

The diagnosis of Anaplasma is typically carried out through morphological identification based on the presence of inclusion bodies located at the margins of erythrocytes. Microscopic examination of blood smears stained with Wright’s–Giemsa is generally suitable for detecting acute anaplasmosis in clinically suspected animals. This study aimed to compare the diagnostic accuracy of microscopic examination and conventional polymerase chain reaction (PCR) for detecting A. marginale in asymptomatic (carrier) cattle. A total of 385 blood samples were collected from cows without clinical symptoms. The sensitivity and specificity of microscopic detection were evaluated against conventional PCR results. The sensitivity and specificity of microscopic results were compared with A. marginale by conventional PCR. The results revealed 3.40% and 12.73% positive animals by microscopy and conventional PCR with significant differences (P=0.03). The value of Kappa between microscopic examination and conventional PCR has indicated a fair level of agreement (0.32). Microscopic examination showed 6.10% sensitivity and 97.40% specificity compared to conventional PCR's 100% sensitivity and specificity. These results indicate that conventional PCR is a more accurate and reliable method for detecting A. marginale in asymptomatic cattle. The limitations of microscopy, particularly in carrier animals, include the very low number of infected erythrocytes, difficulty in identifying well-stained Anaplasma organisms, and challenges in distinguishing A. marginale from A. centrale.

Abstract

Bacterial infections such as Escherichia coli, Staphylococcus aureus, and Salmonella pullorum remain major constraints in native chicken production, reducing productivity and increasing mortality. Excessive use of synthetic antibiotics causes bacterial resistance and residues, thus encouraging the search for safe natural alternatives. This study aimed to evaluate the antibacterial effectiveness of Averrhoa bilimbi L. (bilimbi) leaf extract against bacterial isolates from native chickens and to compare its efficacy with oxytetracycline. The leaves were extracted with 96% ethanol and tested at concentrations of 10%, 20%, and 30% using the disk diffusion method against E. coli isolates. Data were analyzed using the Kruskal-Wallis and Mann–Whitney tests. Results indicated no significant difference (p>0.05) between the inhibition zones of bilimbi leaf extract and oxytetracycline at all concentrations, although descriptively the inhibition zone increased with concentration (average 0.86–1.74 mm). This suggests a concentration-dependent antibacterial activity that remains moderate compared to conventional antibiotics. Bioactive compounds such as flavonoids, tannins, and saponins are presumed to contribute to bacterial growth inhibition. In conclusion, A. bilimbi leaf extract exhibits moderate antibacterial activity. It holds potential as a natural phytobiotic alternative to reduce antibiotic dependence in native chicken production, supporting sustainable and eco-friendly poultry farming. For further research, it is recommended to use: concentration >40% or thick extract from fractionation, further testing of Minimum Inhibitory Concentration (MIC) and Minimum Bactericidal Concentration (MBC).
