Tannins originating from root exudates and plant extracts may act as biological nitrification inhibitors (BNIs) for mitigating nitrous oxide (N₂O) emissions in the context of circular agriculture. However, the differences of condensed (CT) and hydrolysable (HT) tannins in their effects on soil N₂O emissions remain unclear. This study used incubation and pot experiments combined with structural equation modeling (SEM) to evaluate the comprehensive impacts of the proanthocyanidin (PC) and tannic acid (TA) on soil N₂O emissions, considering the influence of fertilizer type (urea vs cattle slurry) and plant (absence vs presence). In contrast to the consistent inhibitory effect of 3,4-dimethylpyrazole phosphate (DMPP) applied to both urea- and slurry-amended soils, PC and TA strongly reduced N₂O emissions from slurry-amended soil, but had differed impact on N₂O (mitigation by PC and enhancement by TA) for urea-amended soil. More importantly, in the presence of cabbage plants, both PC and TA significantly inhibited N₂O emissions under both urea and slurry applications, and improved the biomass production and nitrogen use efficiency to different extents. From a microbial perspective, PC and TA likely reduce N₂O emissions in urea-amended soil by lowering the (nirS + nirK)/(nosZ I + nosZ II) ratio. In slurry-amended soil, however, they achieve N₂O mitigation primarily by increasing the abundance of nosZ II while reducing the abundances of AOA, AOB, nirS, and nirK. In conclusion, the impact of PC and TA on soil N₂O emissions can be fertilizer-specific, however in presence of cabbage plants both PC and TA can mitigate N₂O emissions regardless fertilizer types. In future it warrants more research to examine the effectiveness of PC and TA on N₂O mitigation for different cropping systems under various environmental conditions.

在循环农业的背景下，来自根分泌物和植物提取物的单宁可以作为生物硝化抑制剂（BNIs）来减少一氧化二氮（N2O）的排放。然而，缩合单宁（CT）和水解单宁（HT）对土壤N2O排放的影响差异尚不清楚。本研究采用培养和盆栽试验相结合的结构方程模型（SEM），综合考虑肥料类型（尿素vs牛浆）和植物（有无）的影响，评价了原花青素（PC）和单宁酸（TA）对土壤N2O排放的综合影响。与施用3,4-二甲基吡唑磷酸盐（DMPP）对尿素和浆料改良土壤均有一致的抑制作用相比，PC和TA对浆料改良土壤N2O排放均有显著的抑制作用，但对尿素改良土壤N2O的抑制作用（PC的抑制作用和TA的增强作用）存在差异。更重要的是，在白菜存在的情况下，PC和TA均显著抑制了尿素和浆态施肥下N2O的排放，并不同程度地提高了生物质产量和氮素利用效率。从微生物的角度来看，PC和TA可能通过降低(nirS + nirK)/(nosZ I + nosZ II)比值来减少尿素改良土壤中N2O的排放。然而，在浆料改良的土壤中，它们主要通过增加nosZ II的丰度而降低AOA、AOB、nirS和nirK的丰度来实现N2O的缓解。综上所述，PC和TA对土壤N2O排放的影响可能是肥料特异性的，但在卷心菜植物存在的情况下，PC和TA对N2O排放都有抑制作用，无论肥料类型如何。在不同的环境条件下，不同的种植制度下，PC和TA对N2O的缓解效果有待进一步的研究。

Overlooking fundamental safety measures when applying pesticides in agriculture endangers farmers' health, increases healthcare expenses, and harms the environment. It's well-documented that Bangladeshi farmers use pesticides without taking enough precautions. Employing cross-sectional data, this study utilizes the theory of averting behavior model to assess pesticide handling practices, occupational hazards, and health expenditures among smallholder vegetable producers. While previous Bangladeshi studies focused solely on farmers' attitudes, knowledge, and practices regarding the use of pesticides, the current research identifies a critical gap and presents some new insights. The findings reveal that the application of safety equipment and pesticide container disposal methods was significantly influenced by farmers' investments in health and safety measures (P < 0.05) and the health consequences (P < 0.05) they faced. Farmers spent 4.21 US dollars per farm on health and safety measures against pesticide exposure during the 2023 vegetable season. Most farmers were unaware of properly managing pesticide equipment and disposal techniques for pesticide containers. The logit model results also reveal that farmers were more likely to adhere to precautionary measures and dispose of empty pesticide containers correctly as their age, educational level, and participation in the IPM (Integrated Pest Management) training program increased. These findings emphasize the need for practical IPM training and farmers' educational programs to ensure safe pesticide use. Findings can assist policymakers in understanding the reasons behind the improper application and disposal of pesticide containers. Moreover, the research suggests improved pesticide handling practices can boost sustainable agriculture and reduce health and occupational risks in Bangladesh.

在农业中使用农药时忽视基本的安全措施，危害农民的健康，增加医疗费用，危害环境。有充分的证据表明，孟加拉国农民在没有采取足够的预防措施的情况下使用杀虫剂。本研究采用横截面数据，运用规避行为模型理论，评估小农蔬菜生产者的农药处理方式、职业危害和卫生支出。虽然孟加拉国以前的研究只关注农民对农药使用的态度、知识和做法，但目前的研究发现了一个关键的差距，并提出了一些新的见解。结果表明，安全设备的使用和农药容器处置方式显著影响农民在健康和安全措施上的投入（P < 0.05）和他们面临的健康后果（P < 0.05）。在2023年蔬菜季节，农民在每个农场花费4.21美元用于防止农药暴露的健康和安全措施。大多数农民不知道如何正确管理农药设备和农药容器的处理技术。logit模型结果还显示，随着年龄、受教育程度和参加有害生物综合治理（IPM）培训计划的增加，农民更有可能坚持采取预防措施并正确处理空农药容器。这些研究结果强调了切实可行的IPM培训和农民教育计划的必要性，以确保农药的安全使用。研究结果可以帮助决策者了解不当使用和处置农药容器背后的原因。此外，该研究表明，改进农药处理方法可以促进孟加拉国的可持续农业，减少健康和职业风险。

In recent years, low-income consumers of alcoholic beverages in Chad have converged more towards indigenous beverages, such as Bili-bili. Its production and commercialization, is mostly carried out in unhygienic conditions and often in the grey zone, out of the full control of the Chadian government. This study aims to assess socio-economic and cultural importance of Bili-bili commercialized in N'Djamena (Chad) and its physico-chemical and hygienic characteristics. Firstly, a survey was carried among 715 producers and 795 consumers of Bili-bili. Secondly, forty-five samples of Bili-bili were collected and then used to determine the physico-chemical and microbiological characteristics using standard methods. As a result, Bili-bili was produced exclusively by women, of whom 99.3 % considered as a source of income. Beyond being very used in many traditional ceremonies (78.07 %), the consumption of Bili-bili was motivated by its relatively low cost compared to modern alcoholic beers (56.5 %) and its nourishing aptitude (31.9 %). In lasted case, 65.4 % consume it for the pleasure provided by the alcohol content. Also, Bili-bili could not be kept for more than 24 h with a consistent taste (78.16 %). Its consumption sometimes produces undesirable effects in consumers, such as gastric upset, diarrhea, and vomiting (66.62 %), as well as stomach and headache (32.45 %). The Bili-bili produced had a pH (2.99–4.21) and a composition made of proteins (5.63–12.37 %), lipids (0.03–3.78 %), carbohydrates (81.33–89.23 %) and ethanol (2.33–4.60 g/L). Some samples contained aflatoxin (0.13–1.20 μg/L). The microflora included yeasts (7.39–9.36 log CFU/mL), lactic bacteria (7.11–8.44 log CFU/mL), molds (0.45-0. 78 log CFU/mL), Bacillus cereus (3.33–7.61 log CFU/mL) and sulfite-reducing bacteria (0.75–2.08 log CFU/mL). Bili-bili production has a remarkable socio-economic and cultural importance. However, its hygienic quality remains mediocre, making it a spread of spoilage and/or pathogenic bacteria.

近年来，乍得酒精饮料的低收入消费者更倾向于购买本土饮料，如Bili-bili。它的生产和商业化大多是在不卫生的条件下进行的，往往在灰色地带，不受乍得政府的完全控制。本研究旨在评估在乍得恩贾梅纳商业化的Bili-bili的社会经济和文化重要性及其物理化学和卫生特性。首先，对bilibili的715个生产者和795个消费者进行了调查。其次，采集哔哩哔哩45份样品，采用标准方法测定其理化和微生物特性。因此，bilii -bili完全由女性制作，其中99.3%被视为收入来源。除了在许多传统仪式中被广泛使用（78.07%）外，与现代含酒精啤酒（56.5%）相比，哔哩哔哩的价格相对较低，而且它的营养价值（31.9%）也是推动哔哩哔哩消费的原因。在最后一种情况下，65.4%的人消费它是为了酒精含量所提供的快感。此外，bilibili -bili保存时间不能超过24 h且味道一致（78.16%）。食用它有时会对消费者产生不良影响，如胃不适、腹泻和呕吐（66.62%），以及胃和头痛（32.45%）。所得Bili-bili的pH值为2.99 ~ 4.21，由蛋白质（5.63 ~ 12.37%）、脂类（0.03 ~ 3.78%）、碳水化合物（81.33 ~ 89.23%）和乙醇（2.33 ~ 4.60 g/L）组成。部分样品黄曲霉毒素含量为0.13 ~ 1.20 μg/L。微生物区系包括酵母菌（7.39 ~ 9.36 log CFU/mL）、乳酸菌（7.11 ~ 8.44 log CFU/mL）、霉菌(0.45 ~ 0。78 log CFU/mL)，蜡样芽孢杆菌（3.33-7.61 log CFU/mL）和亚硫酸盐还原菌（0.75-2.08 log CFU/mL）。哔哩哔哩制作具有显著的社会经济和文化重要性。然而，它的卫生质量仍然一般，使它成为腐败和/或致病菌的传播。

The Tomata Valenciana tomato (Solanum lycopersicum L.) landrace, valued for its local importance and unique organoleptic qualities, shows notable intra-varietal diversity. In this study, 46 accessions from three subtypes (‘Blanca’, ‘Masclet’, and ‘Intermitja’) were assessed using 57 morpho-agronomic and 15 biochemical descriptors. High phenotypic variation was observed, particularly in fruit morphology and agronomic traits. Features like fruit weight (FWH), locule number (LCN), and fruit tip formation (FTF) showed high heritability (H² > 0.6). Principal Component Analysis clearly separated subtypes based on morphology: ‘Blanca’, which had larger, rounder fruits with lighter immature colour; ‘Masclet’, with darker green shoulders and pointed tips; and ‘Intermitja’, which showed intermediate traits and greater plant vigour. In contrast, biochemical traits displayed reduced variation among subtypes and low H². These findings highlight the morphological and agronomic diversity of Tomata Valenciana, especially in fruit traits that are valuable for breeding and varietal authentication. The identification of stable, differentiating traits supports conservation efforts and legal recognition through quality labels. The unique profile of the ‘Intermitja’ subtype provides new insights into possible hybridization processes within landraces and their contribution to maintaining genetic diversity in traditional farming systems.

瓦伦西亚番茄（Solanum lycopersicum L.）的地方品种因其在当地的重要性和独特的感官品质而受到重视，表现出显著的品种内多样性。在这项研究中，使用57个形态农艺描述符和15个生化描述符对来自3个亚型（‘Blanca’、‘Masclet’和‘interja’）的46个材料进行评估。表型变异很大，特别是在果实形态和农艺性状上。果实重（FWH）、果室数（LCN）和果尖形成（FTF）等性状表现出较高的遗传力（H2 > 0.6）。主成分分析根据形态清楚地划分出了不同的亚型：“白桦”果实更大、更圆，未成熟的颜色更浅；‘吉祥物’，有深绿色的肩部和尖的尖端；间断性品种表现出中间性状和更强的植株活力。相比之下，生化性状在亚型和低H2之间的差异减小。这些发现突出了瓦伦西亚番茄的形态和农艺多样性，特别是在果实性状方面，这对育种和品种鉴定有价值。鉴定稳定的、有区别的性状有助于保护工作和通过质量标签获得法律认可。“间歇性”亚型的独特特征为地方品种内部可能的杂交过程及其对维持传统农业系统遗传多样性的贡献提供了新的见解。

Navigating sustainability transitions in China's dairy sector: Insights from a multi-dimensional driver analysis 引导中国乳制品行业的可持续转型：来自多维驱动因素分析的见解

China's demand for animal-sourced foods has risen quickly as dietary patterns shift, which has added to environmental pressure. Sustainable dairy production depends not only on natural resource endowments but also on macro-level socio-economic development, meso-level market mechanisms, and farm-level industrialization and resource investment. However, few studies have examined how these drivers interact with one another. In this study, we employ structural equation modeling (SEM) and panel data from 29 Chinese provinces (2006–2022) to build a framework of multidimensional drivers and analyze the spatiotemporal changes in milk production and its associated environmental costs. We find that growing regional gaps in milk output and environmental impacts are driven mainly by socioeconomic growth and dairy industrialization, rather than by natural endowments. Fresh milk supply also remains highly uneven: in more developed regions, demand has grown much faster than local production. For most drivers, increases in milk production are larger than the extra environmental burdens they create. Resource investment is the main exception: its pollution effect is about 1.5 times its production benefit. Although technological and managerial progress has slowed the rise in environmental costs, industrialization has not fully offset the pressure caused by more intensive use of feed and energy. These findings suggest that future policy should focus on improving feed and energy efficiency, better balancing regional supply and demand, and promoting cleaner industrialization with joint carbon–nitrogen management. Overall, the study provides evidence for more sustainable dairy development and context-specific policy design, offering insights into improving agricultural sustainability and resource efficiency in line with the Sustainable Development Goals.

随着饮食模式的转变，中国对动物性食品的需求迅速上升，这加大了环境压力。奶业的可持续生产不仅取决于自然资源禀赋，还取决于宏观社会经济发展、中观市场机制、养殖场工业化和资源投资。然而，很少有研究调查这些驱动因素是如何相互作用的。本研究采用结构方程模型（SEM）和中国29个省份（2006-2022）的面板数据，构建了多维驱动因素框架，分析了牛奶生产及其相关环境成本的时空变化。我们发现，不断扩大的牛奶产量和环境影响的区域差距主要是由社会经济增长和乳制品工业化驱动的，而不是由自然禀赋驱动的。鲜奶供应也仍然高度不均衡：在较发达地区，需求的增长远远快于当地生产的增长。对于大多数司机来说，牛奶产量的增加比它们造成的额外环境负担更大。资源投资是主要的例外：其污染效应约为其生产效益的1.5倍。虽然技术和管理方面的进步减缓了环境成本的上升，但工业化并没有完全抵消饲料和能源的更密集使用所造成的压力。这些发现表明，未来的政策应侧重于提高饲料和能源效率，更好地平衡区域供需，并通过碳氮联合管理促进更清洁的工业化。总体而言，该研究为更可持续的乳业发展和因地制宜的政策设计提供了证据，为根据可持续发展目标提高农业可持续性和资源效率提供了见解。

These findings suggest that future policy should focus on improving feed and energy efficiency, better balancing regional supply and demand, and promoting cleaner industrialization with joint carbon–nitrogen management. Overall, the study provides evidence for more sustainable dairy development and context-specific policy design, offering insights into improving agricultural sustainability and resource efficiency in line with the Sustainable Development Goals.</div></div>","PeriodicalId":34393,"journal":{"name":"Journal of Agriculture and Food Research","volume":"26 ","pages":"Article 102723"},"PeriodicalIF":6.2,"publicationDate":"2026-01-27","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"146078691","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In the current era, the meat supply chain plays a vital role in the food industry. The meat supply chain is experiencing significant challenges due to the increase in demand and Circular Economy (CE) challenges. In the meat supply chain, a huge waste is generated during the meat processing, and it is much needed to manage waste effectively, considering the large quantities of by-products, packaging, and residues generated. The current research focuses on identifying and examining the factors that enable a shift towards a CE for sustainable meat supply chain. The study uses IMF-SWARA and Triangular Fuzzy Bonferroni Mean (TFBM) methods to identify the key enablers and validated through industry and academic experts. Findings indicate that reverse logistics, followed by the principles of reducing, reusing, and recycling (3Rs), and strong leadership commitment, are crucial enablers for adopting a CE in the Indian meat supply chain. This research offers policies and strategies to the managers and practitioners to adopt a sustainable meat supply chain for CE.

Accurate crop yield estimation is crucial for decision-making and planning in modern agriculture with increasing challenges with food security. Yield predictions provide farmers with insights into expected production, facilitating optimized resource allocation, improved agricultural management strategies, and enhanced profitability. This study investigates the application of machine learning (ML) techniques, including Feedforward Neural Networks (FNN), Long Short-Term Memory (LSTM), and Random Forest (RF) models, for predicting crop yields using multi-sensory time-series data that has been collected on two fields over a four-year timeframe. The focus is on corn (Zea mays) and cotton (Gossypium hirsutum) yield, two of the top critical crops in Mississippi region. A multi-sensory dataset was collected using multispectral cameras and LiDAR sensors mounted on unmanned aircraft systems (UAS), along with soil moisture and temperature data from volumetric probes and environmental data from a nearby weather station. Over four years, more than 30 features were extracted weekly from five major categories, with 235 ground truth yield records from plots in the field. The study outlines the methodology for feature selection and examines its impact on yield prediction accuracy. Using percentile root mean square error (RRMSE) and mean absolute percentage error (MAPE) as performance metrics, the study found that the proposed LSTM model produced lower field-wise errors (9 − 21 % MAPE) compared to other models and validation, indicating superior performance in predicting yields across selected weeks. The proposed ML-based approach, validated through year-based and field-wise cross-validation methods, demonstrates the effectiveness of using UAS-collected multi-sensor data for accurate yield estimation in corn and cotton.

在粮食安全面临日益严峻挑战的现代农业中，准确的作物产量估算对农业决策和规划至关重要。产量预测为农民提供了对预期产量的洞察，促进了资源的优化配置，改进了农业管理策略，提高了盈利能力。本研究探讨了机器学习（ML）技术的应用，包括前馈神经网络（FNN）、长短期记忆（LSTM）和随机森林（RF）模型，利用在四年时间框架内从两个领域收集的多感官时间序列数据预测作物产量。重点是玉米（Zea mays）和棉花（Gossypium hirsutum）的产量，这是密西西比地区最重要的两种作物。使用安装在无人机系统（UAS）上的多光谱相机和激光雷达传感器收集了多传感器数据集，以及来自体积探测器的土壤湿度和温度数据以及来自附近气象站的环境数据。在四年的时间里，每周从五个主要类别中提取30多个特征，从实地地块中提取235个地面真实产量记录。该研究概述了特征选择的方法，并考察了其对产量预测精度的影响。使用百分位均方根误差（RRMSE）和平均绝对百分比误差（MAPE）作为性能指标，研究发现，与其他模型和验证相比，所提出的LSTM模型产生了更低的田间误差（9 - 21% MAPE），表明在预测选定周的产量方面具有优越的性能。本文提出的基于机器学习的方法，经过了基于年份和田间交叉验证方法的验证，证明了使用无人机收集的多传感器数据准确估计玉米和棉花产量的有效性。

Cooked poultry products, particularly boiled chicken breast, are highly prone to quality deterioration caused by lipid oxidation, protein degradation, and microbial spoilage. This study developed biodegradable films from pomelo peel pectin and sodium alginate enriched with tannic acid (0.5 % and 1.0 %) and evaluated their physicochemical properties and ability to preserve boiled chicken breast during refrigerated storage. The films were characterized for thickness, color, opacity, UV–visible light transmittance, moisture content, water solubility, water contact angle, barrier properties, mechanical properties, storage stability, antioxidant capacity, and biodegradability. Preservation performance was assessed through pH, color, shear force, thiobarbituric acid reactive substances (TBARS), and total volatile basic nitrogen (TVB-N). The results showed that adding tannic acid significantly reduced film moisture content, water vapor and oxygen permeability while enhancing tensile strength, UV-blocking ability, and antioxidant activity. All films demonstrated visual stability and good biodegradability. When applied to boiled chicken breast, tannic acid enriched films effectively delayed pH increase, discoloration, lipid oxidation, texture deterioration, and TVB-N accumulation compared with unwrapped samples and films without tannic acid. These preservative effects were attributed to the antioxidant and antimicrobial properties of tannic acid, combined with the enhanced barrier and mechanical performance of the film matrix. In conclusion, the addition of 0.5–1.0 % tannic acid to pomelo peel pectin/sodium alginate films improved functional properties and meat preservation, demonstrating their potential as natural based active packaging for cooked poultry products.

煮熟的家禽产品，特别是煮熟的鸡胸肉，很容易因脂质氧化、蛋白质降解和微生物腐败而导致质量恶化。以柚皮果胶和富含单宁酸（0.5%和1.0%）的海藻酸钠为原料制备了生物可降解薄膜，并对其理化性质和冷藏保存煮熟鸡胸肉的能力进行了评价。表征了膜的厚度、颜色、不透明度、uv -可见光透过率、含水量、水溶性、水接触角、阻隔性能、机械性能、储存稳定性、抗氧化能力和生物降解性。通过pH、颜色、剪切力、硫代巴比妥酸活性物质（TBARS）和总挥发性碱性氮（TVB-N）来评估保存性能。结果表明，单宁酸的加入显著降低了薄膜的含水率、透气性和透气性，提高了薄膜的抗拉强度、抗紫外线能力和抗氧化活性。所有膜均表现出视觉稳定性和良好的生物降解性。当应用于煮熟的鸡胸肉时，与未包装样品和未添加单宁酸的薄膜相比，富含单宁酸的薄膜有效地延缓了pH值升高、变色、脂质氧化、质地恶化和TVB-N积累。这些防腐效果归因于单宁酸的抗氧化和抗菌特性，以及薄膜基质的屏障和机械性能的增强。综上所述，在柚皮果胶/海藻酸钠薄膜中添加0.5 - 1.0%的单宁酸可以改善其功能特性和肉类保鲜性，显示出其作为熟家禽产品天然活性包装的潜力。

Traditionally, Tibetan sheep grazed natural pasture without supplements, but growth performance was poor. Feedlot finishing was introduced to improve the average daily gain (ADG) rate of these sheep, but there was concern that it may compromise the nutritional value and characteristic meat flavor. Flaxseed, rich in omega-3 polyunsaturated fatty acids, has been reported to improve meat quality and flavor, but its effects on bodyweight change, serum parameters, and nitrogen (N) metabolism in fattening Tibetan sheep remain unclear. This study aimed to address this knowledge gap. Twenty castrated male Tibetan sheep (43.6 ± 2.11 kg) were assigned randomly to a control (CON) group and an 8 % flaxseed-supplemented (FS) (n = 10 per group) for 50 days. CON sheep had greater (P < 0.05) dry matter intake, nitrogen (N) excretion, and N retention, tended to reduce ADG, while feed conversion rate (FCR) and N utilization efficiency did not differ between groups. FS sheep had lesser (P < 0.05) serum concentrations of total protein, globulin, glucose and malondialdehyde, but a greater (P < 0.01) concentration of glutathione peroxidase. Urinary purine derivatives excretion tended to be greater (P < 0.01) in CON than FS sheep, whereas rumen microbial N production, microbial protein synthesis efficiency and renal urea-N reabsorption did not differ between groups. In conclusion, flaxseed tended to reduce growth performance and increase FCR but improved antioxidant capacity without affecting N utilization efficiency in feedlot Tibetan sheep.

传统上，藏羊以天然牧草为食，不加补料，生长性能较差。为了提高这些羊的平均日增重，引入了饲养场育肥，但担心会影响这些羊的营养价值和特色肉味。据报道，亚麻籽富含omega-3多不饱和脂肪酸，可以改善藏羊的肉质和风味，但其对育肥藏羊体重变化、血清参数和氮代谢的影响尚不清楚。本研究旨在解决这一知识差距。选取20只（43.6±2.11 kg）阉割的公藏羊，随机分为对照（CON）组和添加8%亚麻籽（FS）组（每组10只），试验期50 d。CON羊的干物质采食量、氮排泄量和氮滞留量显著增加（P < 0.05），有降低平均日增重的趋势，而饲料系数和氮利用效率各组间无显著差异。FS羊血清总蛋白、球蛋白、葡萄糖和丙二醛浓度较低（P < 0.05），但谷胱甘肽过氧化物酶浓度较高（P < 0.01）。对照组尿嘌呤衍生物排泄量高于对照组（P < 0.01），而组间瘤胃微生物氮产量、微生物蛋白质合成效率和肾脏尿素氮重吸收率无显著差异。综上所述，亚麻籽有降低藏羊生长性能、提高饲料比、提高抗氧化能力的趋势，但不影响氮素利用效率。

Fungal pathogens remain a major constraint to global food production, while resistance to chemical fungicides continues to increase. Although Trichoderma spp. are extensively studied as microbial biocontrol agents, no integrated synthesis has yet connected the field's bibliometric growth with its mechanistic and technological foundations. This study analyzed 3082 Scopus-indexed publications (1975–2024) using R (bibliometrix) and VOSviewer to track publication trends, global collaboration networks, and thematic evolution. Results were linked to primary literature on molecular mechanisms and field performance. Annual output grew from 39 (2000) to 285 (2023), with an 8.6 % compound annual growth rate. Collaboration patterns reveal two central axes India-Eastern Mediterranean and China-United States aligned with national bioinput agendas. Thematic clusters show a transition from single-strain antagonism to integrative approaches involving omics, microbial ecology, and formulation design. Trichoderma efficacy is driven by antibiosis, enzymatic lysis, and hormone-mediated defense, shaped by rhizosphere conditions and formulation matrices. Advances in encapsulation, osmoprotection, and chemical compatibility have improved field persistence and efficacy. This study identifies the need for standardized reporting, omics-informed strain selection, and regulatory-aligned formulation strategies to improve the reproducibility, scalability, and adoption of Trichoderma-based biocontrol as a resilient component of sustainable agriculture.

真菌病原体仍然是全球粮食生产的主要制约因素，而对化学杀菌剂的耐药性继续增加。虽然木霉作为微生物生物防治剂被广泛研究，但还没有将该领域的文献计量学增长与其机制和技术基础联系起来的综合研究。本研究使用R （bibliometrix）和VOSviewer分析了1975-2024年间3082篇scopus索引的出版物，以跟踪出版物趋势、全球合作网络和主题演变。结果与分子机制和现场表现的主要文献相关联。年产量从2000年的39台增长到2023年的285台，复合年增长率为8.6%。合作模式显示印度-东地中海和中国-美国两个中心轴与各国生物投入议程一致。专题集群显示了从单一菌株拮抗到涉及组学、微生物生态学和制剂设计的综合方法的转变。木霉的功效由抗生素、酶解和激素介导的防御驱动，由根际条件和制剂基质形成。在包封、渗透保护和化学相容性方面的进步提高了田间持久性和有效性。本研究确定了标准化报告、基于组学的菌株选择和与监管一致的配方策略的必要性，以提高以木霉为基础的生物防治的可重复性、可扩展性，并将其作为可持续农业的弹性组成部分。
