Indonesian sheep, shaped by survival, reproduction and productivity in humid tropical climates, may carry genomic regions associated with local adaptation and economically important traits that remain largely unexplored. This study performed genetic diversity analysis on 17,534 SNPs derived from the OvineSNP50 BeadChip genotyping array, involving 120 individuals among five local Indonesian sheep breeds: Batur, Garut, Sakub, Sumatra and Thin‐tail. Analysis of genetic structure, incorporating PCA, maximum‐likelihood phylogenetics analysis and Admixture analyses, demonstrated that each population displayed a uniquely homogeneous and distinctive ancestry profile, with the exception of Sakub and Thin‐tail. Additionally, a close genetic relationship among Sakub, Garut and Thin‐tail sheep was identified. We employed four complementary approaches of within and cross population selection signature analyses to identify putative selection signatures within 13 genomic regions. Several genes identified within the selection signature regions are potentially associated with the immune system (e.g., ATRNL1 , DDX58 and NELFCD ), wool traits and pigmentation (e.g., CERS4 and EDN3 ), reproductive traits (e.g., GNPDA2, NAMPT and NDRG1 ), milk traits (e.g., SLC39A8, ST3GAL1 and EVI5L ), meat traits (e.g., PIK3CG, CDHR3 and ANGPTL4 ), and adaptive traits (e.g., SLC26A4 and NDUFB6 ). Understanding the candidate genomic areas under selective pressure in sheep breeds may aid in identifying the associated genes and improve our comprehension of their involvement in local adaptation. Consequently, this research provides a preliminary genomic resource for the conservation and utilization of these sheep genetic resources in Indonesia.

Indonesia is endowed with many goat breeds, which include meat-type, dual-purpose, and dairy goats. Studies show that some breeds of goat, including dairy and meat goats in Indonesia, are at risk of extinction, while the level of risk of extinction for others is not yet known. This study was conducted to explore the genetic diversity and phylogenetic relationship of seven goat breeds found in Yogyakarta and Central Java, which included Saanen, British Alpine, Bligon, Anglo Nubian, Toggenburg, Nigerian dwarf, and the Crossbreed of Anglo Nubian with PE. DNA was extracted from blood samples of 31 goats. Partial sequences of the cytochrome b gene from mtDNA with 430 bp, were amplified by using PCR with forward primer 5’-CAACATCCGAAAGACCCACC-3’ and reverse primer 5’-AACAGGATCGAACAACCCCA-3’. The sequenced results were then aligned with 4 reference sequences from GenBank (D84201.1, AB004074.1, NC_005044.2, and KY564254.1) by using MEGA 11 software. NJT constructed in MEGA 11 showed two main clades; the first main clade contains Saanen, British Alpine, Bligon, Anglo Nubian, Toggenburg, and Crossbreed of Anglo Nubian with PE, and the second main clade contains only Nigerian dwarf goat. A total of 3 hypervariable sites were detected at 284th (T>C), 371st, (C>T) and 372nd (C>T) in some cyt b gene sequences of goat breeds in study and resulted into the change in amino acids from Isoleucine to Threonine at 284th and Phenylalanine to Serine at 371st & 372nd. Furthermore, 5 polymorphic sites, 5 number of mutations, and 8 number of haplotypes were found across all samples. Overall haplotype diversity and nucleotide diversity were 0.716 ±0.058 and 0.00251±0.00035, respectively. The revealed low genetic diversity among seven dairy goats breeds in Yogyakarta and Central Java, indicating a narrow genetic base and high genetic homogeneity which may reduce adaptability and increase extinction risk.

Iop Conference Series Earth and Environmental Science, 2026
Kebumen Ongole Grade (KOG) cattle possess several advantages over other local beef cattle, including larger body size and superior reproductive traits. This study aimed to determine the relationship between calving interval (CI) and dam frame score (DFS), dam body mass index (DBMI), and offspring body mass index (OBMI). A total of 142 pairs of Kebumen Ongole Grade dams and their offspring were observed. The measured variables comprised frame score and biometric traits such as body weight (BW), withers height (WH), body length (BL), hip height (HH), along with reproductive parameter calving interval. Data were analyzed using descriptive statistics, correlation, and regression analyses. The results showed a significant positive correlation between CI and DFS (r = 0.166), and non-significant negative correlations between DFS and DBMI (r = –0.131), and between DFS and OBMI (r = –0.090). The regression equation describing the relationship between CI and the three independent variables was: CI (years) = 0.891 + 0.026(DFS) + 0.003(DBMI) + 0.023(OBMI). The results indicate that skeletal frame score exerts a modest but notable impact on reproductive traits, whereas body mass index of dams and calves shows little association with calving interval. Nevertheless, body mass index remains a critical indicator of health, as both under- and over-conditioned cows are at higher risk of metabolic disorders, reproductive challenges, and reduced fertility. In Kebumen Ongole Grade cattle, calving interval showed a weak but significant positive relationship with frame score, while dam and offspring body mass indexes had weak, non-significant effects.

The Teropong Temanggung sheep, an indigenous Indonesian breed from Central Java, represents an important genetic resource for smallholder farmers. However, molecular genetic information on this population remains limited. To clarify its maternal genetic background, this preliminary study analyzed the mitochondrial cytochrome b (Cyt b) gene sequence. Blood samples from six (n = 6) Teropong Temanggung sheep were collected, DNA was extracted, and a complete Cyt b gene fragment was amplified and sequenced. Three single-nucleotide polymorphism sites produced two haplotypes. Analysis using MEGA software showed low haplotype diversity (Hd = 0.3333) and nucleotide diversity (Pi = 0.00088). Phylogenetic reconstruction revealed that five samples clustered within haplogroup B and one within haplogroup A, suggesting a mixed maternal lineage origin. These findings provide preliminary baseline information on maternal genetic variation in Teropong Temanggung sheep; however, given the limited sample size and the use of a single mitochondrial marker, they should not be interpreted as evidence of genome-wide genetic distinctiveness. The results serve as a foundation for future studies incorporating larger sample sizes and nuclear genetic markers to better characterize this local sheep population.

< 0.001), which indicated a moderate but statistically significant population structure.3. Multiple haplogroups in Indonesian chickens reflect complex maternal origins and past gene flow from outside populations. These findings highlighted the importance of understanding genetic structure to inform the management and characterisation of native breeds. The distinct maternal lineages in Merawang and Nunukan showed historical introductions, while the close relationship among Tukong and Kampung chickens implied interbreeding under extensive rearing systems.

Rhodomyrtus tomentosa , a medicinal plant abundant in polyphenols and indigenous to Indonesia, exhibits significant anticancer potential. This research investigated the effects of Chitosan-formulated extracts of R. tomentosa on HER2 expression and apoptotic signaling pathways, specifically Caspase-3, Fas Ligand, and Cytochrome c , in a rat model of breast cancer induced by 7,12-dimethylbenz [a]anthracene (DMBA). The study employed in-vivo, immunohistochemical, biochemical, and in silico analyses. Phytochemical profiling using LC-HRMS revealed the presence of predominant flavonoids, including myricetin, myricitrin, and quercetin. The compounds demonstrated significant binding affinities to HER2 and apoptotic proteins via molecular docking, with molecular dynamics simulations indicating improved structural stabilization, especially by myricitrin and quercetin. Histological and ELISA evaluations indicated that oral administration of R. tomentosa extract at escalating doses (100, 150, and 200 mg/kg BW) significantly decreased expression levels of HER2, FasL, and Cytochrome c , while also modulating Caspase-3 in both serum and mammary tissues. The maximum dosage (200 mg/kg BW) closely matches the therapeutic efficacy of doxorubicin. The findings indicate that Chitosan-formulated extracts of R. tomentosa reduces breast tumor progression by downregulating HER2 expression and inducing apoptosis through intrinsic and extrinsic pathways. The findings highlight the potential use of R. tomentosa as a bioactive herbal agent in the development of functional food-based adjuvants or complementary therapies for breast cancer treatment. • Rhodomyrtus tomentosa reduces HER2 expression in breast tissue. • In vivo study confirms apoptotic pathway modulation by the plant extract. • LC-HRMS identified myricitrin and quercetin as dominant active compounds. • In silico docking shows strong affinity of flavonoids to HER2 and Caspase-3. • Nanoextract offers potential as plant-based adjuvant for breast cancer therapy.

The increasing incidence of chemotherapy-induced nephrotoxicity underscores the urgent need for effective nephroprotective agents. This study uniquely integrates in silico and in vivo approaches to evaluate the nephroprotective potential of Rhodomyrtus tomentosa (haramonting), addressing a critical gap in current literature. Unlike previous studies focusing solely on antioxidant effects, this research targets key inflammatory cytokines— interleukin-6 (IL-6), interleukin-10 (IL-10), and transforming growth factor-beta 1 (TGF-β1) and Vascular endothelial growth factor receptor 1 (VEGFR1)known to mediate renal injury. Objectives included compound identification, molecular docking with cytokine targets, and in vivo validation using Wistar rats (n = 36) treated with R. tomentosa extract (100–300 mg/kg) for 30 days. Kidney function markers (urea, creatinine), cytokine expression (ELISA and immunohistochemistry), and histological features were evaluated. In silico analysis revealed strong binding affinity of dominant flavonoids (myricitrin, myricetin) to cytokines and stable protein-ligand dynamics. In vivo, treatment reduced creatinine and urea levels, improved renal histoarchitecture, and upregulated protective cytokines. These findings position R. tomentosa as a promising adjunct therapy to preserve renal integrity during chemotherapy. The study provides a novel cytokine-centered framework for evaluating herbal nephroprotective agents and supports further clinical investigation.

Background and Aim: Sheep farming is a vital component of Indonesia’s agricultural economy, where the demand for meat continues to rise. Indigenous Garut sheep are well-adapted to local environments and are known for their high reproductive efficiency, but they have low growth rates. Conversely, Dorper sheep are renowned for their rapid growth and carcass quality, but they exhibit longer lambing intervals under tropical conditions. Crossbreeding offers a strategy to combine the strengths of both breeds. This study aimed to evaluate maternal reproductive performance and pre-weaning growth traits in purebred Dorper, Garut, and Dorper × Garut crossbred sheep under a commercial breeding system in Indonesia. Materials and Methods: A retrospective observational study was conducted on 1,744 ewes (1,498 Garut, 209 F1 Dorper × Garut, and 93 Dorper) and 3,248 lambs (2,846 F1 Dorper × Garut, 253 B1 backcrosses, and 149 Dorper) from a commercial enterprise in West Java. Data included lambing interval, litter size, birth weight, weaning weight, pre-weaning mortality, average daily gain (ADG), reproductive index, and productivity index. Statistical analyses employed one-way analysis of variance with Duncan’s multiple range test for post hoc comparisons. Results: F1 Dorper × Garut crossbred ewes demonstrated significantly shorter lambing intervals (206.65 ± 2.75 days) than pure Dorper (265.66 ± 1.14 days), comparable to Garut ewes (209.10 ± 1.08 days). However, Garut ewes had superior litter size (1.77 ± 0.18) relative to both crossbred (1.33 ± 0.04) and Dorper ewes (1.30 ± 0.42). In growth performance, Dorper lambs excelled in birth weight (3.35 ± 0.07 kg), weaning weight (23.93 ± 0.57 kg), and ADG (203.88 ± 4.65 g/day). F1 Dorper × Garut lambs showed significantly higher weaning weight (19.48 ± 0.35 kg) and ADG (165.34 ± 2.95 g/day) compared with Garut lambs (15.36 ± 0.10 kg; 130.47 ± 0.83 g/day). Conclusion: F1 Dorper × Garut crossbreeding synergizes Garut’s reproductive efficiency with Dorper’s growth performance, yielding crossbreds well-suited for tropical meat production. While Garut maintains a prolificacy advantage, F1 crossbreds deliver improved pre-weaning growth, supporting their use in commercial fattening programs. Maintaining pure Garut flocks for breeding and employing F1 crossbreds for production may enhance productivity and sustainability in Indonesia. Future research should assess carcass traits, multigenerational crossbreeding, and economic feasibility. Keywords: Dorper sheep, Garut sheep, Crossbreeding, Lambing interval, Productivity index, Indonesia.
