Buffaloes are vital livestock in South-East Asia, attributed to their adaptation to hot and humid climates as well as their capacity to produce high-quality milk and meat. However, the texture of buffalo meat is suboptimal and its slow growth rate restricts the development of the buffalo farming industry. Consequently, studies exploring the key biochemical factors associated with buffalo muscle development have become a research focus. CircRNAs are a class of non-coding RNAs which can function as molecular sponges, participate in protein scaffold formation, and encode short peptides. Previous studies have shown that circRNAs are capable of regulating muscle development; however, relatively few reports have addressed their association with buffalo muscle development. In this study, data from Western blotting and RT-qPCR showed that circCOPS8 significantly enhanced the differentiation of buffalo myoblasts while inhibiting their proliferation (p < 0.05). In contrast, in a mouse model of muscular injury, circCOPS8 prevented the repair of injured muscles. Additionally, RIP-qPCR assays confirmed that circCOPS8 could bind to IGF2BP3 (p < 0.05). Furthermore RT-qPCR and transcriptome sequencing results revealed that circCOPS8 inhibited cell growth by upregulating the expression of genes such as ATR (p < 0.05). Our findings suggested that circCOPS8 promoted the differentiation and apoptosis of buffalo myoblasts while inhibiting their proliferation. The inhibition of cell proliferation was primarily mediated by the binding of circCOPS8 to IGF2BP3 and the promotion of ATR gene expression. This study investigated the role and underlying mechanism of circCOPS8 in buffalo myoblasts, which will extend our understanding of non-coding RNA-mediated regulation of buffalo muscle development, with the ultimate goal of improving the meat quality of buffaloes.

Reproductive efficiency substantially determines livestock productivity, and suboptimal fertility continues to limit productivity across species. Inhibin immunization represents a novel strategy to enhance fertility by neutralizing inhibin’s negative feedback on follicle-stimulating hormone (FSH) secretion. This comprehensive review synthesizes evidence from ruminants (cattle, sheep, goats, camels, and buffalo) and non-ruminants (pigs, donkeys, rabbits, and avian species), evaluating inhibin immunization mechanisms and reproductive outcomes. Immunoneutralization of inhibin consistently elevates FSH, activin A, and estradiol, thereby promoting ovarian follicular recruitment and spermatogenesis. In females, this approach has been widely reported to increase ovulatory activity and improve embryo production and quality. In males, immunization enhances testicular function and semen quality while mitigating seasonal infertility. However, species-specific variations in response and dose-dependent luteal suppression (particularly in pigs) necessitate optimized protocols. While inhibin immunization shows consistent benefits when integrated with multiple ovulation and embryo transfer (MOET) and in vitro fertilization (IVF), standardized protocols and long-term fertility data remain insufficient for commercial implementation. This review identifies critical evidence gaps and safety considerations essential for clinical translation. Full article

Antibiotic residues in water buffalo milk are a food-safety concern, yet depletion data are scarce. The purpose of this study was to characterize the depletion profiles of amoxicillin (AMOX) and its two major metabolites, amoxicilloic acid (AMA) and amoxicillin diketopiperazine-2′,5′-dione (2,5-DKP), in Anatolian water buffalo milk after a single intramuscular administration and to estimate a milk withdrawal time relative to the EU MRL. We tested the hypothesis that AMOX concentrations would decrease below the EU MRL over successive milkings and that AMA and 2,5-DKP would exhibit depletion kinetics distinct from the parent compound. Five lactating Anatolian water buffaloes received a single intramuscular injection of amoxicillin (15 milligrams per kilogram). Milk was collected at each milking (twice daily) for seven days and analyzed by liquid chromatography–tandem mass spectrometry with quantification limits below the European Union maximum residue limit for amoxicillin in milk (4 micrograms per kilogram). Amoxicillin peaked at the second milking (mean 13.65 micrograms per kilogram), mean concentrations fell below the maximum residue limit from the sixth milking, and they became non-quantifiable from the tenth milking onward. Two major metabolites, amoxicillinic acid and amoxicillin diketopiperazine-2′,5′-dione, peaked earlier (2,5-DKP Tmax 12 h) or at higher concentrations (AMA Cmax 32.64 µg/kg vs. AMOX 13.65 µg/kg) and remained detectable up to the thirteenth milking, with longer apparent terminal half-lives (32.0 and 52.8 h) than amoxicillin (23.5 h); the mixed-effects model confirmed different depletion rates among analytes (milking × analyte interaction p = 4.63 × 10⁻⁵). A log-linear withdrawal model applying the EMA 95/95 tolerance limit indicated that the first time point at which the upper tolerance limit fell below the EU MRL was 84.7 h after dosing; rounded up to the next 12 h milking interval, this corresponds to a reported withdrawal period of 96 h (≈8 milkings). These results provide species-specific residue kinetics for amoxicillin in Anatolian buffalo milk and support considering metabolites in monitoring and withdrawal-time decisions. Full article

This study evaluated key reproductive and productive parameters of the Romanian buffalo reared under temperate-continental conditions. Data collected over a 30-year period (1990–2020) from 310 female buffaloes raised at the Şercaia Buffalo Research and Development Station (Brașov County, Romania) were analyzed. Only animals that completed their first gestation and calving within the herd and had complete lifetime records were included. Buffaloes were monitored longitudinally from first calving until the end of their productive life, regardless of the reason for exit. The evaluated traits included age at first calving, number of lactations, milk yield, milk fat content, and the effect of calf sex on milk production. Data were analyzed using descriptive statistics, group comparisons, and linear regression. Mean age at first calving was 51.6 ± 14.0 months, and females completed an average of 7.8 ± 3.0 lactations, indicating good reproductive longevity. Buffaloes calving male offspring produced significantly more milk per lactation (1272 ± 267 L) than those calving female offspring (1099 ± 244 L; p < 0.01). Milk fat content averaged approximately 7% and did not differ significantly between females giving birth to female offspring and those giving birth to male offspring (p > 0.05). Overall, the results indicate good productive stability and reproductive durability of the Romanian buffalo under semi-intensive management and confirm its adaptability to temperate environments.

Water buffaloes in northern Australia occupy tropical wetlands where conditions favour the proliferation of arthropod vectors and the transmission of vector-borne livestock diseases. However, their role in maintaining economically important arboviruses such as Akabane virus (AKAV), bluetongue virus (BTV), and bovine ephemeral fever virus (BEFV) remains poorly understood. These three viruses cause significant production losses in cattle and pose ongoing surveillance challenges in remote areas. To assess exposure to these viruses, a convenience sample of feral water buffaloes from the Northern Territory, Australia, was collected. Commercial enzyme-linked immunosorbent assays (ELISAs) were used to detect antibodies against AKAV, BTV, and BEFV in 119 samples stored as dried blood on filter paper. Seroprevalence was 18.5% for AKAV, 66.4% for BTV, and 15.1% for BEFV. These results are consistent with previous serological studies in northern Australian cattle, confirming the circulation of these pathogens in the region. Our findings demonstrate that water buffaloes are exposed to these economically important arboviruses and may contribute to their maintenance, highlighting the need to consider feral buffalo populations in regional arbovirus surveillance strategies and livestock disease management.

Genomic improvement and sustainable breeding of Mediterranean buffalo are hampered by the lack of breed-specific genomic resources compared with bovine. To address this gap, we aimed to identify a comprehensive set of high-confidence single-nucleotide polymorphisms (SNPs) in Mediterranean buffalo and evaluate their informativeness across other buffalo populations. A total of 58 whole-genome sequencing samples, from three different sets, were merged through the integration of short- and long-read sequencing technologies. Variants, both unique and shared among datasets, were identified using a combination of bioinformatic tools to increase the reliability of the dataset. From these, over 11 million high-confidence biallelic SNPs were identified in the Mediterranean breed. The same SNPs were also tested in additional populations (other rivers and swamps) to evaluate their polymorphism and missingness. These results provide a robust genomic resource for Mediterranean buffalo, overcoming the limitations of bovine-derived genotyping tools available today. The identified SNPs dataset lays the basis for the development of a breed-specific SNP array, providing a dense and informative set of markers that could support cost-effective SNP chip development compared with existing arrays and sequencing technologies. This resource will facilitate more accurate genomic selection, precision breeding, and the conservation of genetic diversity in the Mediterranean buffalo population. Full article

Melatonin (MLT) is a potent antioxidant that reduces oxidative stress (OS)-induced sperm damage. However, few studies have explored its effects in the field investigated here. This study aimed to evaluate the effects of MLT supplementation in extenders used for staining, sorting, and freezing on the quality of sorted Nili-Ravi buffalo sperm, embryo development after in vitro fertilization (IVF), and pregnancy outcomes following artificial insemination (AI). Computer-aided sperm analyzer (CASA) showed that progressive motility (PM) and velocity parameters of sorted, frozen–thawed sexed sperm were higher in the MLT-treated groups (p < 0.05). Fluorescence microscopy demonstrated that MLT significantly improved sperm plasma membrane integrity after staining and increased the proportion of frozen–thawed sex-sorted sperm with high mitochondrial membrane potential (HMMP) (p < 0.05). Raman spectroscopy further identified several distinctive Raman bands at 936, 1300, and 1651–1652 cm⁻¹, which may serve as biomarkers for assessing sperm quality. Additionally, cleavage rate, blastocyst formation, and pregnancy rates following IVF and AI were higher in the MLT-treated group (p < 0.05). In conclusion, MLT can serve as a valuable additive during sperm sex-sorting procedures to enhance sperm quality, thereby improving embryo developmental competence and pregnancy outcomes.

This review provides a comparative examination of current methods for evaluating fertility and semen quality in mammals, with emphasis on livestock species. It is based on a structured search and analysis of 316 academic publications retrieved from major scientific databases, including Elsevier, Springer, Taylor & Francis, and MDPI, as well as other repositories, covering literature published between 1938 and 2025. This review examines advanced semen analysis techniques, including computer-assisted semen analysis (CASA) systems and assays for assessing chromatin integrity, DNA damage, seminal plasma composition, sperm membrane proteins, and functional parameters such as migration capacity, membrane integrity, acrosomal status, capacitation, morphology, viability, concentration, motility, and volume. Methods for semen collection are also outlined. The synthesis focuses on the comparative assessment of techniques and recent findings for major ruminant and monogastric livestock species: cattle (Bos taurus and Bos indicus), buffalo (Bubalus bubalis), sheep (Ovis aries), goats (Capra hircus), and pigs (Sus domesticus). A brief historical overview of assisted insemination is presented, incorporating relevant procedures and managerial factors that affect fertility outcomes. Advances in genetics related to reproductive health are also discussed. This synthesis seeks to integrate existing knowledge and guide future research in reproductive science for both animal production and human medicine. Full article

We studied the shelf life of fresh buffalo meat in polyamide/polyethylene (PA/PE) packaging during refrigerated storage for 14 days, when treated with cinnamon–clove (C-C) and nutmeg (Nut) powders, along with lavender essential oil (LEO). Microbiological (total viable count, Pseudomonas spp., Brochothrix thermosphacta, Enterobacteriaceae, and lactic acid bacteria), antibacterial (Salmonella Typhimurium and Staphylococcus aureus), physicochemical and biochemical (pH, moisture, color, total fat, hemoglobin and heme iron, 2-thiobarbituric acid, mercaptans, antioxidant activity, and total phenolic content), and sensory (color, odor, texture, and taste) analyses were carried out. The results showed that C-C and Nut powder extracts exhibited significant (p < 0.05) antioxidant and antibacterial activity, higher than LEO; however, all treatments delayed lipid oxidation. Based primarily on sensory evaluation, the shelf life extension of buffalo meat was 2–3 days for LEO and Nut powder, and 4–6 days for C-C powder. Factor analysis indicated the critical days of refrigerated storage for the evolution of spoilage-related biochemical parameters. Full article

Although higher technical efficiency is theoretically expected to enhance farm sustainability, empirical evidence in livestock systems remains ambiguous. This study investigates the interplay between technical efficiency and sustainability using data from 72 farms in Tokat, Türkiye, selected via stratified random sampling. Technical efficiency was calculated using Data Envelopment Analysis (DEA), while a multidimensional Sustainability Index was constructed using the analytic hierarchy process (AHP) for weighting dimensions. Determinants of inefficiency were estimated using a Tobit model. Results revealed an average technical efficiency of 0.717 and a Composite Sustainability Index of 0.41, classifying the sector as “moderate” but fragile. Crucially, the Kruskal–Wallis test showed no statistically significant difference in sustainability scores across efficiency groups (p > 0.05). This finding confirms a “structural disconnect,” demonstrating that high technical efficiency does not guarantee sustainability because of systemic bottlenecks such as dysfunctional organizations and infrastructure deficits. Furthermore, Tobit results showed that non-farm income and internet access were positively associated with technical efficiency, whereas indebtedness was negatively associated. Consequently, achieving lasting sustainability requires a shift from simple productivity support to structural modernization policies, including the integration of sustainability-oriented criteria such as institutional strengthening, environmental management, and financial capacity into existing support schemes.

Trypanosoma vivax is a hemoprotozoan parasite of major veterinary importance affecting domestic ungulates in Africa and the Americas. While traditionally addressed within cattle-centered paradigms, accumulating evidence indicates that water buffaloes (Bubalus bubalis) are both clinically susceptible and epidemiologically significant hosts. This structured narrative review provides a host-centered synthesis of global evidence on T. vivax infection in buffaloes, integrating pathogenesis, transmission biology, epidemiology, diagnostics, chemotherapy, and integrated control. The analysis encompasses literature from 2000 to 2025 and incorporates seminal experimental studies published prior to 2000 that established buffalo susceptibility and reservoir competence. Evidence from cyclical (tsetse-mediated) and mechanical transmission systems is comparatively interpreted to clarify host–parasite dynamics. The Amazon biome is discussed as a model system for high-density buffalo production under mechanical vector pressure, offering case-based contextualization without geographic restriction. Particular attention is given to immunopathological mechanisms, chronic low-parasitemia carriage, diagnostic sensitivity in subclinical infections, emerging trypanocide resistance, and ecological constraints on vector control. Controversies and buffalo-specific knowledge gaps are highlighted throughout. By adopting a buffalo-centered analytical framework, this review supports translational diagnostics, targeted surveillance, and sustainable control strategies for trypanosomiasis in tropical livestock systems.

The surplus in the production of buffalo milk determines the possibility of finding alternative solutions for its use. Indeed, the utilization of milk in cosmetic formulations has been met with great approval by consumers, primarily due to its highly appreciated emollient characteristics. The aim of this research was to test an alternative use of buffalo milk in the production of artisanal solid soaps, using buffalo milk as raw material and Lavender, Thyme, and Grape pomace as sources of natural bioactive compounds. The analytical approach was focused on using vegetable materials in three forms: fresh, dried, and freeze-dried. For this purpose, the chemical features of both raw materials and artisanal soaps were determined in order to understand the feasibility of these productions. All formulated artisanal soaps revealed good chemical characteristics, such as a low moisture content, and got high scores in the sensory evaluation, with those with Lavender and Grape pomace being the most appreciated formulations. Furthermore, adding vegetable materials increased the bioactive molecules content, as demonstrated by the data obtained from total polyphenol content and antioxidant activity. Therefore, the addition of plants and vegetables to the formulation could represent an innovative production of natural soaps and be a further element for the market trends. Full article

The bovine tongue is a complex and very important muscular and gustatory organ, yet a comprehensive understanding of its gustatory apparatus across diverse genetic resources remains elusive. In this study, we conducted a multidimensional analysis of the lingual morphology and taste bud (TB) distribution in 40 specimens from 12 representative bovine breeds and species across China, encompassing Bos taurus taurus (Taurine cattle), Bos taurus indicus (Zebu cattle), Bubalus bubalis (water buffalo), and Bos grunniens (domestic yak). Morphometric measurements and histological quantifications were integrated to evaluate the influence of species, sex, age, and geographical factors. Given the relatively limited sample size per breed, these findings are presented as exploratory research. Our results revealed that yak and water buffalo showed the most distinct morphological patterns of mechanical papillae compared to the other populations. Taurine and Zebu cattle displayed more similar lingual morphology traits. Although high phenotypic correlations were observed between lingual morphometric parameters and quantitative papillae indicators, factors such as age, altitude, and feeding methods showed minimal influence on lingual phenotypic variation within this cohort (p > 0.05). Furthermore, we constructed a topological atlas of TB distribution, revealing that TB distribution patterns are decoupled from macro-anatomical dimensions, highlighting the complexity of the bovine gustatory system. These findings provide a quantitative baseline for ruminant comparative anatomy and offer structural insights into the evolutionary adaptation and nutrient regulation mechanisms of diverse bovine species in varying environments.

Milk is a primary source of vital nutrients and bioactive components fundamental to the growth and development of both newborn animals and humans. Produced by economically significant livestock species (including cattle, buffaloes, goats, sheep and camels), milk is a complex matrix rich in caseins, vitamins, fats, and proteins. Beyond its classical nutritional profile, milk serves as a pivotal vehicle for milk-derived extracellular vesicles (mEVs). These specialized food-derived EVs (fEVs) exert pleiotropic effects that resonate with the One Health paradigm, linking animal well-being and human nutrition to broader ecosystem stability. mEVs offer unique advantages, such as high biocompatibility and gastrointestinal stability, also rendering them potential therapeutic tools as drug delivery systems. However, challenges remain regarding the standardization of mEVs and the variability of their molecular cargo. This review provides a comprehensive comparative analysis of mEVs across a diverse taxonomic range, including bovines, water buffaloes, yaks, camels, goats, pigs, horses, donkeys, and humans, highlighting their distinct functional signatures. Indeed, a critical issue in mEV research is the isolation process: recommendations to minimize contamination from milk fat globules and casein micelles (which can cover EV signals) are given. Finally, current detection methods and instrumentation, with a specific focus on advancing flow cytometry (FC) approaches are discussed. Key insights include the use of conventional FC (with fluorescence triggering, the necessity of rigorous controls and calibration, and the utility of bead-based assays to overcome resolution limits) and imaging flow cytometry (IFC). In both technical approaches, the application of different EV generic fluorescent markers and the strategic selection of tetraspanins (i.e., CD9, CD63, CD81), is mandatory: we emphasize that selecting the correct antibody clones and accounting for inter-species cross-reactivity are essential steps for ensuring the accuracy and reproducibility of mEV research across mammalian species.

Taraxacum mirabile Wagenitz, one of the endemic riches of Anatolia, is a species that has remained largely unexplored regarding its enzyme inhibition profile despite its pharmacological potential. The effects of T. mirabile aerial and root extracts, obtained at different polarities, were scrutinized in this study against two important enzymes: lactoperoxidase (LPO), which plays a vital role in the innate immune system, and xanthine oxidase (XO), which is prominently associated with hyperuricemia and oxidative stress. The aerial and root portions of the plant were extracted into fractions of varying polarities using petroleum ether, dichloromethane, ethyl acetate, and butanol. LPO was isolated from buffalo milk (881.6-fold purification, 22.5% yield, and 1249.9 EU/mg specific activity) via affinity chromatography and used in in vitro inhibition assays alongside commercial bovine XO enzyme. The results showed that the ethyl acetate fraction of the aerial part of the plant exhibited the strongest LPO inhibition (IC₅₀: 15.60 ± 0.77 µg/mL) among the fractions. The petroleum ether fraction of both the aerial part (IC₅₀: 11.17 ± 0.94 µg/mL) and the root part (IC₅₀: 11.61 ± 0.59 µg/mL) had the highest inhibitory effect for the XO enzyme. These distinct inhibition profiles allow for significant insights into how plant extracts with varying polarities modulate XO and LPO enzymes. In conclusion, the significant inhibitory activity of T. mirabile extracts toward LPO and XO enzymes highlights their potential as a natural source for developing effective enzyme inhibitors, which could be useful for therapeutic applications.
