Abstract

Clinical mastitis in dairy cattle poses severe economic and health challenges globally, exacerbated by rising antimicrobial resistance (AMR). This systematic review and meta-analysis evaluated the prevalence of mastitis-causing pathogens and their antibiotic resistance profiles from 2010 to 2023. Following PRISMA guidelines, 45 eligible studies were analyzed using a random-effects model. The pooled estimates revealed that Gram-positive bacteria are the primary causative agents, predominantly Staphylococcus intermedius (42.30%) and Staphylococcus aureus (32.97%). Analysis of resistance proportions demonstrated alarming rates against commonly used commercial antibiotics, notably Penicillin (45.2%) and Ampicillin (40.5%). Crucially, methicillin-resistant S. intermedius strains exhibited absolute resistance (100%) to oxacillin and cefoxitin. High inter-study heterogeneity (I² > 75%) was observed, with meta-regression confirming a statistically significant temporal increase in resistance over the past decade. These findings underscore the critical threat of AMR in the dairy sector. The study concludes that there is an urgent necessity for implementing standardized diagnostic procedures, continuous molecular surveillance, and rigorous, evidence-based localized antibiotic stewardship policies to mitigate the spread of resistant pathogens and ensure sustainable dairy production.

Abstract

Feed is the single largest cost component in beef cattle enterprises, and understanding how it scales with herd size is essential for the economic sustainability of smallholder operations. This study examined the relationship between the number of cattle owned and the annual feed cost at H. Risnoto beef cattle farm in Tegal Regency, Central Java, Indonesia. A survey approach with a quantitative design was applied, using farm records covering the period 2020–2024. The number of beef cattle owned (head) and the corresponding total annual feed cost (Indonesian Rupiah, IDR) were collected and analysed using simple linear regression to determine the direction, strength, and statistical significance of the relationship. The analysis produced the regression equation Ŷ = 355,045,838 + 6,292,075X, with a coefficient of determination (R²) of 0.993 and a correlation coefficient (r) of 0.997 (p < 0.01). These results indicate a very strong, positive, and statistically significant association: each additional head increased the annual feed cost by approximately IDR 6.29 million. The strongly positive slope confirms that larger herds require proportionally greater quantities of forage and concentrate, raising total feed expenditure. However, the average feed cost per head rose only modestly across herd-size levels (from about IDR 3.95 million to IDR 4.57 million per head per year), suggesting limited economies of scale at the farm level. Farmers are advised to align herd size with their feed-supply capacity and to adopt efficient feeding strategies—such as the use of local feed ingredients and fermentation (silage) technology to keep the enterprise efficient and sustainable.

Abstract

The Kacang goat is the most widely distributed indigenous goat of Indonesia, yet evidence on its production potential remains scattered across heterogeneous local studies. This review aimed to synthesize the productive, reproductive, and adaptive potential of the Kacang goat to inform conservation and genetic improvement. Following the PRISMA 2020 guideline, we retrieved peer-reviewed articles published between 2000 and 2025 from Scopus, Web of Science, PubMed, and ScienceDirect, supplemented by hand-searching; 47 studies met the eligibility criteria, and 31 provided extractable quantitative data. A random-effects meta-analysis of litter size across ten studies yielded a pooled estimate of 1.85 kids per birth (95% CI 1.78–1.92; I² = 58%). Adult body weight ranged from 22 to 30 kg, kidding interval from 217 to 271 days, and the doe reproduction index from 2.3 to 3.1 kids per doe per year, with pre-weaning survival commonly exceeding 90%. Carcass percentage ranged from 44 to 47%, and the breed showed strong thermotolerance and the ability to maintain reproduction on low-quality forage. Although small-framed, the Kacang goat combines high prolificacy, early maturity, and superior environmental resilience. Structured selection within nucleus flocks and controlled crossbreeding, rather than indiscriminate grading-up, are recommended to realize its potential while preserving genetic identity.

Abstract

Animal slaughterhouses (Rumah Potong Hewan, RPH) are strategic public facilities for supplying safe animal-source food, but when sited within a settlement, their operation directly affects residents' environmental comfort. This study characterized the residents living around the RPH in Wiradesa District, Pekalongan Regency, Central Java, and quantified their perception of the facility along two axes: environmental burden (odor, waste, water pollution) and socio-economic benefit. A descriptive field survey was conducted with 28 residents living within a 1 km radius, selected purposively to represent the four cardinal directions from the facility; perception was measured on a three-point Likert scale (1 = not, 2 = moderately, 3 = very disturbing/beneficial) and summarized with a class-range procedure whose cut-offs are reported explicitly for each sub-variable. Most respondents were male (71.4%), of productive to mature age, senior-high-school educated (46.4%), and worked as laborers (57.1%). Across the nine environmental indicators, perception scored 536 of a possible 756 (70.9%), classified as "moderately disturbing"; within this, the waste sub-variable alone reached the highest ("disturbing") category (142/168; 84.5%), driven by direct discharge of liquid waste into the river and open accumulation of solid waste, whereas odor and water pollution were "moderately disturbing." In contrast, residents rated the facility as "beneficial" (139/168; 82.7%), principally for easy access to meat (85.7%) and local employment. Reported as two directional scales rather than a single composite, the results describe a social dilemma in which a genuine, waste-led environmental burden is tolerated because of the RPH's economic and food-supply value. Prioritizing wastewater treatment (IPAL) and routine sanitation is recommended to lower the environmental burden while preserving the benefits the community values.

Abstract

This study aimed to determine the effect of rearing system (intensive and free-range) and village location (Karanggintung, Karangcegak, and Datar) on the proximate quality (crude protein, crude fat, moisture, and ash content) of duck eggs in Sumbang Subdistrict, Banyumas Regency. A 2×3 factorial Completely Randomized Design (CRD) was used, consisting of six treatment combinations and three replications, giving 18 experimental units. Proximate data were analyzed using Analysis of Variance (ANOVA), followed by the Least Significant Difference (LSD) test for significant effects. Results showed that rearing system, location, and their interaction had a highly significant effect (P<0.01) on duck egg moisture content. The highest moisture content was recorded in the intensive system in Datar Village (65.73%), while the lowest was in the free-range system in Karanggintung Village (58.81%). In contrast, rearing system, location, and their interaction did not significantly affect crude protein, crude fat, or ash content (P> 0.05). These findings indicate that moisture content is the proximate parameter most responsive to rearing management and location, whereas the macronutrient quality of duck eggs remains relatively stable, giving farmers flexibility in choosing a rearing system; the free-range system is more suitable for the processed-egg industry because of its lower moisture content.

Abstract

Goat milk is a functional food, but its characteristic goaty flavor lowers consumer acceptance, so flavor diversification is needed as a masking strategy. This study analysed consumer preference for four goat-milk variants (original, chocolate, strawberry, and melon) produced by the Mendha Milk business unit, evaluated organoleptically/hedonically by 30 semi-trained panelists on a five-point scale for the attributes of aroma and flavor. Data were analysed using the non-parametric Friedman test followed by the Wilcoxon test. Flavor diversification had a highly significant effect (P<0.01) on consumer preference for both attributes, confirming that added flavors act as masking agents that minimise the goaty flavor. The melon variant was most preferred for aroma (mean 4.47, very much liked), whereas the strawberry variant was most preferred for flavor (mean 4.23, very much liked); the original variant scored lowest on both (3.07 and 2.70). The four-flavor innovation effectively shifted consumer perception of goat milk, with melon and strawberry as the most preferred variants, offering a viable product-development strategy for goat-milk businesses.
