Peranakan Etawa (PE) goat farming is one of the growing livestock sectors in Indonesia. Indonesia needs a sustainable breeding system that can guarantee the availability of goats. Estrus synchronization is a necessity that can help uniform the breeding time and manage the time of pregnancy and birth. Artificial estrus synchronization techniques that use a combination of Prosterone and Zinc minerals give good results of estrus synchronization in goats. The Aim of this research is to understand the combination efectiveness of estrus synchronization technique with progesterone acetate and Zinc supplementation. The design of this study used two treatment groups, each group consisting of three does PE goats. Estrus synchronization of experimental animals in treatment 1 and 2 was carried out using polyurethane sponge implant method which contained medroxi progesterone acetate 60 mg. Group 1 was given Sponge Progesterone for nine 9 days while giving Zinc (Zn) mineral supplement (Elemental Zn 20 mg, Kimia Farma) orally given 7 times. The frequency of Zinc administration every day begins during intra vaginal sponge insertion. Group 2 was treated same as group 1 with 14 days of implant time and 7 times of Zinc supplementation.The results showed that both treatments occurred estrus simultaneously with good estrus quality. Both treatments show the results of the estrus 8 score assessment with the estrus 3-9 range. The maximum estrus quality’s value of group 2 was higher (8.33 ± 0.57) compared to group 1 (8.0 ± 1.0). The estrus duration of group 2 occurs for 24 hours and group 1 for 7 hours. Estrus onset of Group 2 is earlier (58 hours) than group 1 (75 hours). Both treatment groups showed an increase in temperature at period of the occurrence of estrus. Body temperature during estrus time was 38.7 ± 0.20 0C to 39.60 ± 0.26 0C. The conclusion of this study is that in both treatments of estrus synchronization using sponge progesterone and zinc supplementation can cause estrus synchronization effectively . The duration of estrus in group 1 (9 days of implant) was Shorter than group 2 (14 days of implant). The onset of estrus time of group 1 (9 days of implant) was longer than Group 2 (14 days of implant). The body temperature of the experimental animals increases with the occurrence of estrus.

Coccidiosis is an intestinal parasitic disease caused by Eimeria. The investation of Eimieria can negatively alter poultry health and reduce the productivity of poultry. Decreasing of broiler production can cause economic loss to the farmer and further to the domestic economic. This paper aimed to estimate the economic loss due to coccidiosis in broiler chicken in Central Java Province. The calculation was made based on two parameters: epidemiologic parameter and economic parameter. The data for calculation was based on previous research data and current data. The estimation was calculated using two approaches: direct and indirect method. The direct loss related to the production system cost and extra cost due to coccidiosis cases while indirect loss related to the economic loss in Central Java that could be affected by coccidiosis. The result showed that the direct loss estimation was Rp 3,371,408,383,426,- and indirect loss was Rp 141,430,086,- with a total estimation of economic loss in Central Java due to coccisiosis was Rp 3,371,549,813,512,-. This estimation indicates the importance of coccidiosis control program in poultry industry.

Background and Aim: Mastitis is an important disease that can reduce milk production and farmer income as well as negatively affect human health. This study aimed to summarize dairy mastitis in Indonesia, both subclinical mastitis (SCM) and clinical mastitis (CM), and its prevalence in different provinces, the diagnostic methods, and the animal species. Materials and Methods: Relevant studies on mastitis in dairy animals in Indonesia were obtained from PubMed, Scopus, ProQuest, Google Scholar, and Garuda. The title and abstract were screened for the eligibility of the studies. The full text of the selected studies was assessed and the data were extracted for analysis. To determine the pooled estimate of the prevalence of mastitis, a random-effects model was performed using the “Meta” and “Metaphor” packages in the R software version 4.2.2. The heterogeneity of several characteristics (mastitis type, provinces, animal species, and diagnostic methods) was evaluated through subgroup meta-analysis. Meta-regression analysis was conducted to assess the trend of mastitis prevalence reports over time. Publication bias was evaluated using Egger’s test and a funnel plot. Results: A total of 735 studies were retrieved for the title and abstract screening, which resulted in the final selection of 37 studies with a total of 6050 samples for meta-analysis. The pooled estimate of mastitis prevalence in dairy animals in Indonesia was 59.44% (95% confidence interval [CI], 52.39%–66.49%). Based on mastitis type, SCM had a significantly higher prevalence than CM (58.24% [95% CI, 51.26%–65.23%] vs. 3.31% [95% CI, 1.42%–5.19%]). No significant difference was observed in the analysis of other subgroups. Among provinces, Central Java had the highest prevalence (66.62% [95% CI, 49.37%–83.87%]), whereas Yogyakarta had the lowest (41.77% [95% CI, 14.96%–68.58%]). Based on animal species, cow and goat had a prevalence of 63.42% (95% CI, 55.97%–70.86%) and 44.96% (95% CI, 28.26%–61.66%), respectively. Based on the diagnostic method, the California mastitis test resulted in 60.08% (95% CI, 52.11%–68.06%) and the Institut Pertanian Bogor test, 56.00% (95% CI, 41.20%–70.81%). No significant change in the prevalence of mastitis in Indonesia was observed from 2003 to 2022. Conclusion: This study demonstrates that the pooled estimate of mastitis prevalence in dairy animals in Indonesia is >50%. Based on subgroup analysis, SCM had a higher prevalence than CM; however, the prevalence between provinces, detection methods, and animal species in the 2003–2022 periods was not significantly different. A mastitis control strategy needs to be developed to reduce the prevalence of mastitis and further loss in milk production. Keywords: animals, cow, Indonesia, subclinical mastitis.

Resident in Kokap, Kulon Progo, Yogyakarta Province has another income sector, that is dairy goat (Etawah Crossbreed) farming and they have been joining into farm group, which is called Kelompok Ternak. There are many bacteria that causing dairy goat intra mamary infection, thus the milk production will be contaminated. Two hundred and four (204) milk samples from 103 lactation goat in four farm groups in Kokap, Kulon Progo, Yogyakarta is used in this study. Out of these, 21 samples (10,29%) were detected strong positive (++ and +++) for subclinical mastitis by using California Mastitis Test (CMT). Among this positive result, the next step was bacteria detection. This tests were held in Preclinic Laboratory Animal Health Study Program, Vocational School, UGM. The samples were inoculated in blood agar, then colony was identify by Gram staining. The next steph is biochemical tests using McConkey Agar (MCA) and eosin methylene blue (EMB) as a selective media for Gram negative bacteria,  manitol salt agar (MSA) as selective media for Staphylococcus, sugar fermented broth (glucose, lactose, mannitol, maltose, and sacharose), Kigler iron agar (KIA), lysine iron agar (LIA), motility indole ornithin (MIO), and Simmon’s citrate. The result was Staphylococcus aureus (80%), Staphylococcus epidermidis (20%), Escherichia coli (10%), and Klebsiella pneumoniae (10%).

Abstract Colibacillosis is one of the most problematic issues in the boiler industry. However, the antibiotic overuse has induced Escherichia coli resistance so that other alternative to reduce colibacillosis is needed. One of the alternatives is using aloe vera (Aloe barbadensis Miller), which has been widely used as an antibacterial agent. This study aims to isolate and identify E. coli from the broiler drinking water source and test the aloe vera antibacterial activity against it. Escherichia coli were isolated from well in three broiler farms in Moyudan District, Sleman, Yogyakarta that previously had colibacillosis. Escherichia coli were isolated using eosin methylene blue (EMB) agar and the metallic sheen colony was tested to confirm the biochemist reaction. The pure isolate of E. coli was used in the aloe vera inhibition test using Muller Hinton agar (MHA) by a Well Diffusion method. Aloe vera was processed using aquades and ethanol 70%. The aquades infusion was diluted into 12.5%, 25%, 50%, 75%, and 100% and the extract ethanol 70% was diluted into 10%, 12.5, %, 25%, 40%, and 50%. The bacterial identification showed that one of three samples contained E. coli which was then used for inhibition test. The result showed no inhibition zone in the aquades infusion while ethanol extract showed an inhibition zone in concentration 25%, 40%, and 50% of aloe vera extract with a diameter 19.5 mm, 24 mm, and 25 mm. It can be concluded that aloe vera ethanol extract has inhibitory activity against E. coli in poultry drinking water with a minimum concentration of 25%.  Keywords: Aloe vera; Broiler drinking water; Escherichia coli; Inhibitory activity   Abstrak  Colibacilosis masih menjadi permasalahan dalam industri broiler. Penggunaan antibiotik berlebihan telah menyebabkan resistensi sehingga perlu alternatif lain. Salah satu alternatif adalah menggunakan bahan alami seperti adalah lidah buaya (Aloe barbadensis Miller) yang memilliki aktivitas antibakteri. Penelitian ini bertujuan untuk mengisolasi dan mengidentifikasi E. coli dari sumber air minum di kandang broiler serta menguji aktivitas inhibisi lidah buaya terhadap bakteri tersebut. Air yang digunakan sebagai sumber E. coli berasal dari sumur di tiga peternakan broiler di Kecamatan Moyudan, Sleman, Yogyakarta yang memiliki riwayat infeksi colibacilosis. Bakteri E. coli diisolasi menggunakan media eosin methylene blue (EMB) dan diuji sifat biokimia untuk mengkonfirmasi sifat bakteri E. coli. Isolat murni E. coli digunakan pada uji daya hambat bakteri dengan metode difusi sumuran menggunakan media Muller Hinton Agar (MHA). Lidah buaya diproses menggunakan aquades dan ethanol 70%. Infusa aquades diencerkan menjadi konsentrasi 12,5%, 25%, 50%, 75%, dan 100% dan ekstrak ethanol 70% diencerkan menjadi 10%, 12., %, 25%, 40%, dan 50%.  Hasil isolasi menunjukan bahwa satu sumber air dari sumur di Desa Kolowenang mengandung E. coli yang kemudian digunakan pada pengujian daya hambat. Hasil pengujian menunjukan tidak ada daya hambat yang terbentuk pada infusa aquades sedangkan ekstrak etanol lidah buaya 25%, 40%, dan 50% menunjukan adanya zona hambat sebesar 19,5 mm, 24 mm, dan 25 mm berturut-turut. Ekstrak etanol lidah buaya pada penelitian ini memiliki kemampuan menghambat pertumbuhan E. coli yang bersumber dari air minum broiler dengan konsentrasi terendah 25%.

IntroductionThe carcinogenic liver fluke Opisthorchis viverrini is a major public health problem in the Mekong basin region. The liver flukes can induce cholangiocarcinoma, a bile duct cancer that causes a significant burden of mortality and economic loss. Various public health interventions have been conducted to reduce opisthorchiasis but the prevalence of O. viverrini remains high in endemic regions. The aim is to quantify the effectiveness of public health interventions in reducing the prevalence of O. viverrini infection.Methods and analysisSeven databases (including PubMed, SCOPUS, Web of Science, EMBASE, ScienceDirect, Thai thesis database and TCI (Thai journals online)) will be searched from initiation through to 2022 to identify studies of interventions to reduce the prevalence of O. viverrini infection. The prevalence, incidence or number of O. viverrini-infected people will be used as the source of O. viverrini prevalence data. A conventional meta-analysis and a Bayesian network meta-analysis will be conducted to undertake direct and indirect comparisons of different interventions. Meta-regression will be used to determine the effect of each intervention. The risk of bias will be assessed using the Cochrane Collaboration’s risk of bias tool. Heterogeneity between studies will be determined by forest plots and I2 and publication bias investigated with funnel plots and the Egger’s test.Ethics and disseminationEthical approval will not be required because this study will only use published data. The final report of this review will be disseminated through publication in a peer-reviewed scientific journal and will also be presented at relevant conferences.PROSPERO registration numberCRD42022323066.
