Dampak Ekonomi Kejadian Avian Influenza di Kabupaten Pinrang pada Peternakan Ayam Petelur

Ardilasunu Wicaksono — 2026-06-13

Avian influenza reduces egg production in layer chickens, leading to significant economic losses for farmers. Pinrang, one of the largest egg-producing regions in South Sulawesi, continues to face recurring cases of avian influenza. This study aimed to estimate the economic losses associated with avian influenza incidences in layer chicken farms in Pinrang District. The economic impact was assessed using partial analysis by calculating both direct and indirect costs of avian influenza at the district and farm levels on an annual basis. Input parameters included epidemiological and economic data obtained from the Department of Livestock and Plantation of Pinrang District, scientific literature, commodity and veterinary product records, and veterinary practitioners. Sensitivity analysis was performed to evaluate the effect of uncertain parameters on the estimated outcomes. The results indicated that the total economic loss reached IDR 12.4 billion/year at the district level and IDR 9 million/year at the farm level. The largest allocation of the losses was attributed to reduced egg production (38.1%), followed by vaccination costs (25.9%). The most influential parameters affecting the estimates were disease incidence and egg prices. In conclusion, avian influenza causes substantial economic losses in Pinrang District, highlighting the importance of preventive measures to minimize future costs.

Identifikasi Keberadaan Gen mecA, mecC dan blaZ pada Isolat Tersimpan Staphylococcus aureus Asal Susu Sapi Perah Mastitis Subklinis

Ghina Nazalia — 2026-06-13

Mastitis is an inflammation of the bovine udder that can reduce both the quantity and quality of milk. This condition is commonly caused by Staphylococcus aureus which has the ability to develop resistance to antibiotics. The most frequently reported resistance is associated with methicillin-resistant Staphylococcus aureus (MRSA), with the possible involvement of β-lactamase enzymes. This study aimed to identify resistance-encoding genes, namely mecA, mecC, and blaZ, in stored Staphylococcus aureus isolates obtained from the milk of dairy cows with subclinical mastitis. The study was conducted using phenotypic and genotypic approaches to reconfirm the species of Staphylococcus aureus. The identification results showed that 22 of 28 isolates (78,6%) were confirmed as Staphylococcus aureus. Antibiotic susceptibility testing using the Kirby–Bauer method showed that 2 of 22 isolates (9,1%) were resistant to penicillin G, while all isolates (100%) remained sensitive to cefoxitin. PCR results showed that 5 of 22 isolates (22,7%) carried the blaZ gene, whereas none of the isolates (0%) were detected to carry the mecA or mecC genes. These findings indicate that the resistance mechanism in stored Staphylococcus aureus isolates from dairy cows with subclinical mastitis in Tanjungsari District is associated with β-lactamase production.

Tingkat Keamanan Pakan Hewan Kesayangan Berbahan Dasar Daging Mentah dan Pakan Basah Berdasarkan Jumlah Total Mikrob, Enterobacteriaceae, dan Staphylococcus aureus

The growing popularity of raw meat-based diets (RMBDs) for pets has raised considerable concern regarding microbiological hazards due to the absence of heat treatment during production. This study aimed to evaluate and compare the microbiological quality of RMBDs and Wet pet food by assessing Total Viable Count (TVC), Enterobacteriaceae, and Staphylococcus aureus. Three RMBDs brands and one Wet pet food brand, derived from chicken and beef, were analyzed, with five samples collected from each. Microbial enumeration was performed using standard plate count methods. The mean TVC in chicken- and beef-based RMBDs was 3.9 × 10⁵ ± 5.6 × 10⁵ CFU/g and 2.7 × 10⁵ ± 3.0 × 10⁵ CFU/g, respectively, compared with 3.3 × 10² ± 2.6 × 10² CFU/g in wet pet food. The mean Enterobacteriaceae counts were 3.2 × 10⁴ ± 4.8 × 10⁴ CFU/g in chicken-based RMBDs, 2.8 × 10³ ± 2.6 × 10³ CFU/g in beef-based RMBDs, and 0 CFU/g in wet pet food. The average counts of S. aureus were 2.4 × 10⁴ ± 3.0 × 10⁴ CFU/g in chicken-based RMBDs and 2.1 × 10⁴ ± 5.6 × 10⁴ CFU/g in beef-based RMBDs, whereas no S. aureus was detected in wet pet food. Overall, RMBDs exhibited significantly higher microbial loads compared with Wet pet food and did not meet international microbiological safety standards. These findings highlight the potential public health and animal health risks associated with RMBDs consumption.

The Pengaruh Kombinasi Anestesi Ketamine-Medetomidine dengan Premedikasi Acepromazine dan Atropine Sulfate terhadap Profil Hematologi Anjing Lokal

Tri Utami — 2026-06-13

This study aimed to evaluate the effect of the combination of ketamine-medetomidine anesthesia with two different types of premedication, namely acepromazine and atropine sulfate, on hematological parameters in local dogs. A total of six male local dogs aged 1–2 years with a body weight of 8–15 kg were used as experimental animals and randomly divided into two groups (three dogs each). Group 1 was given acepromazine premedication (0.05 mg/kg BW, im), while group 2 was given atropine sulfate premedication (0.04 mg/kg BW, sc). Fifteen minutes later, both groups were induced with ketamine (10 mg/kg BW, im) and medetomidine (30 µg/kg BW, im). Blood samples were taken through the saphenous vein at three observation times: before anesthesia (T0), 30 minutes (T30), and 60 minutes (T60) after anesthesia. Parameters measured included total erythrocytes, hemoglobin levels, hematocrit values, and total leukocytes using a hematology analyzer. Data analysis showed no significant differences (p>0.05) between time points or between treatment groups. The erythrocyte, hemoglobin, hematocrit, and leukocyte counts in both groups remained within the normal physiological range. However, the group 1 showed a tendency for decreased hematological values after anesthesia due to the sedative effect of acepromazine, while the group 2 showed a transient increase due to the pre-anesthetic stress response and mild dehydration. The results of this study indicate that the combination of ketamine-medetomidine anesthesia with acepromazine or atropine sulfate premedication does not cause significant hematological changes and is safe for use in local dogs during clinical anesthetic procedures.

Genetic Variation Analysis of FSHB Gene Exon 3 in Goats (Capra hircus) Using in Silico Restriction Fragment Length Polymorphism (RFLP)

Hendro Sukoco — 2026-06-13

Studi ini bertujuan untuk melakukan analisis in silico awal Restriction Fragment Length Polymorphism (RFLP) pada ekson 3 gen Hormon Perangsang Folikel Beta (FSHB) pada kambing (Capra hircus) menggunakan enzim restriksi BspMAI dan PstI. Empat sekuens ekson 3 gen FSHB yang telah dipublikasikan, masing-masing sepanjang 310 bp, diperoleh dari basis data NCBI dan dianalisis dengan digesti restriksi virtual. Hasil analisis memprediksi dua pola restriksi pada sekuens yang dianalisis: pola tidak terpotong sepanjang 310 bp dan pola terpotong yang menghasilkan fragmen sepanjang 200 bp dan 110 bp. Pola tidak terpotong sepanjang 310 bp ditemukan pada tiga sekuens, sedangkan pola 200 bp dan 110 bp ditemukan pada satu sekuens. Hasil ini menunjukkan kemungkinan adanya perbedaan situs restriksi pada atau di sekitar situs pengenalan BspMAI/PstI pada ekson 3 gen FSHB kambing. Namun, karena penelitian ini terbatas pada analisis komputasional sekuens publik dan tidak melibatkan sampel biologis, amplifikasi PCR, pengurutan, pencernaan enzim restriksi langsung, atau validasi elektroforesis, temuan ini masih bersifat pendahuluan. Penelitian lebih lanjut menggunakan penyelarasan sekuens berganda, identifikasi SNP, dan validasi PCR-RFLP laboratorium pada populasi kambing sebenarnya diperlukan untuk mengkonfirmasi potensi penggunaan BspMAI/PstI dalam studi genetika kambing
