Although life cycle assessment and nutrient balance approaches are commonly used to estimate emissions, they often provide limited insight into internal nitrogen transformations and provide restricted support for farm-scale decision making. This study aimed to develop a simplified compartmental model to quantify nitrogen flows and losses across the main components of intensive dairy farms. Methods The model combines process-based relationships with a limited set of farm-specific input data, including herd composition, feeding strategy, housing systems, and manure management practices. Nitrogen dynamics are represented through interconnected compartments describing the animal, barn, treatment, storage, and land application phases, enabling the identification of key stages contributing to gaseous nitrogen losses. The model was applied to ten commercial Holstein dairy farms located in the Po Valley (Northern Italy). Results Total gaseous nitrogen losses averaged 7.20 ± 6.43% of nitrogen intake in untreated systems, with ammonia volatilization representing the dominant loss pathway. Farms adopting anaerobic digestion showed increased nitrogen retention in digestate, despite higher overall losses associated with subsequent handling stages. A preliminary comparison between simulated and measured nitrogen concentrations in selected manure and digestate matrices indicated a generally consistent representation of nitrogen partitioning, although systematic overestimations were observed for liquid matrices during the early management stages. Discussion Given the limited number of monitored farms and the absence of a comprehensive quantitative validation, the results should be interpreted as indicative of nitrogen flow patterns rather than precise emission estimates. Nevertheless, the proposed framework provides a transparent and data-efficient tool for exploring farm-specific nitrogen balances, supporting scenario analyses and nutrient management strategies, and contributing to the transition toward more circular and environmentally efficient dairy production systems.","引言 奶牛生产系统中的氮管理是决定环境绩效和养分利用效率的关键因素，因为在粪污管理链条中可能发生大量氮损失。尽管生命周期评价和养分平衡方法常用于估算排放量，但它们往往对系统内部氮转化过程的揭示有限，对牧场尺度的决策支持也较为受限。本研究旨在开发一个简化的分室模型，以量化集约化奶牛场主要组成部分中的氮流动与损失。方法 该模型将基于过程的机理关系与有限的牧场特定输入数据相结合，包括畜群结构、饲喂策略、圈舍系统及粪污管理措施。氮动态通过描述动物、牛舍、处理、储存和农田施用等阶段的相互关联分室进行表征，从而识别导致气态氮损失的关键环节。该模型应用于位于波河平原（意大利北部）的十个商业荷斯坦奶牛场。结果 在未处理系统中，总气态氮损失平均占氮摄入量的7.20±6.43%，其中氨挥发是主要的损失途径。采用厌氧消化的牧场在消化液中表现出更高的氮保留率，尽管后续处理环节相关的总损失有所增加。对选定粪污和消化液基质中模拟氮浓度与实测氮浓度的初步比较表明，模型对氮分配的模拟总体一致，但在管理早期阶段对液态基质存在系统性高估。讨论 鉴于监测牧场数量有限且缺乏全面的定量验证，研究结果应被解读为氮流动模式的指示性参考，而非精确的排放估算值。尽管如此，所提出的框架为探索牧场特定氮平衡提供了一种透明且数据高效的工​​具，可支持情景分析和养分管理策略制定，并有助于推动奶牛生产系统向更加循环和环境高效的方向转型。",null,"Frontiers in Sustainable Food Systems","2026-09-04T00:00:00Z","论文",10,false,68,{"impact":17,"substance":18,"depth":19,"authority":20,"freshness":21,"relevant":22,"comment":23},12,20,18,13,5,1,"论文提出简化分区模型量化奶牛场氮流与损失，为农场氮管理提供决策工具，具行业参考价值。",[25],{"name":10,"url":6},[27,28,29,30],"氮管理","循环农业","农业环保","奶牛养殖",{"code":32,"slug":33,"name":34,"path":35,"parent_code":36},"C2","ruminants","草食牲畜","\u002Ftopic\u002Flivestock\u002Fruminants","C",[],{"status":39,"locked":14,"version":40,"method":41,"evidence":42},"classified","2026-10-22.2","rules",{"candidates":43,"agricultural_evidence":46},[44,51,58],{"code":32,"score":45,"supported":46,"title":47,"abstract":48,"tags":50},4,true,[],[49],"奶牛",[30],{"code":52,"score":53,"supported":46,"title":54,"abstract":55,"tags":57},"F3",3,[],[56],"养分管理",[],{"code":59,"score":22,"supported":14,"title":60,"abstract":61,"tags":62},"H8",[],[],[28],[64,65],"农业环保 奶牛养殖 循环农业 氮管理","农业环保 奶牛养殖","农业环保奶牛养殖循环农业氮管理-1714","10.3389\u002Ffsufs.2026.1926333",{"doi":67,"openalex_id":69,"authors":70,"venue":10,"cited_by_count":85,"oa_url":86,"card":87,"direction":91,"ingested_from":93},"W7208709391",[71,74,76,79,82],{"name":72,"orcid":73},"Giulia Ferronato","https:\u002F\u002Forcid.org\u002F0000-0001-9153-8540",{"name":75,"orcid":9},"Anna Simonetto",{"name":77,"orcid":78},"V.

朱虹\n\n前不久，寒区奶牛液体粪肥还田技术推介观摩现场会暨畜禽液体粪污资源化利用专题培训会在哈尔滨举行。本次会议由黑龙江省黑土保护利用研究院牵头，联合黑龙江省奶业协会、省奶牛产业技术协同创新推广体系主办，聚焦寒区畜禽粪污资源化利用、绿色种养循环农业发展，开展技术研讨与现场观摩交流。\n\n黑龙江作为全国核心优质奶源基地，规模化奶牛养殖产业体量庞大。但受高寒气候制约，区域土壤封冻期长、粪污还田窗口期短，叠加粪污贮存风险高、转运难度大、施用技术粗放、专用装备短缺等痛点，长期存在奶牛液体粪污“存不住、运不出、还田难”困境。这造成养殖端有机养分资源与种植端耕地肥力需求时空错配，既污染养殖区域生态环境，又浪费珍贵的有机农业资源，制约种养循环农业高质量发展。\n\n针对寒区养殖粪污资源化利用的技术短板，黑龙江省黑土保护利用研究院研究员高洪生团队，依托国家重点研发计划、黑龙江省农业科学院创新工程等项目，历经近10年持续攻关、多点田间试验与示范验证，成功研发出适配寒区农业生产节律的奶牛液体粪肥还田成套技术体系，破解高寒地区粪污资源化利用的核心难题。\n\n这套技术构建起一条“冬天存得住、春天运得出、田里施得准”的流水线：先把粪水集中起来，固液分离后把液体粪肥密封贮存发酵，解决封冻期不能还田、容易污染的问题；等土地解冻，用像“脐带”一样的泵和软管把粪肥直接从贮存池送到田间，替代罐车拉运，降低成本；还田前检测粪肥养分、测算地块承受力，再按季节用喷洒、深埋注入或滴灌等方式精准施入，抓住春、夏、秋的还田窗口。这样就把粪污从“污染负担”变成了“肥料资源”。同时，项目配套的托管式（脐带）输送装备国产化率超95%，大幅降低大型牧场粪肥田间输送成本、提升作业效率，为技术规模化落地筑牢装备根基。\n\n多年示范应用数据显示，该技术提质增效成果显著。2022—2024年，黑龙江省累计推广应用面积达83.31万亩，消纳还田奶牛液体粪肥467.41万立方米。示范片区实现化肥减量10%—20%，玉米粮食作物增产7.58%以上，同步达成粪污无害化处置、化肥减量增效、黑土地力培肥三重效益，构建起生态、农业、产业共赢的发展模式。2026年，寒区奶牛液体粪肥还田技术正式入选黑龙江省农业主推技术名单，标志着该项科研成果全面完成试验示范迭代，迈入标准化、规范化、规模化推广新阶段。\n\n来源：科技日报\n\n举报\n\n评论

dairy cattle lameness assessment using a 38-keypoint whole-body YOLOv8 pose framework","https:\u002F\u002Fdoi.org\u002F10.14202\u002Fvetworld.2026.4286-4306","Background and Aim: Lameness is a major health, welfare, and production concern in dairy cattle, whereas conventional visual locomotion scoring is intermittent and susceptible to observer-dependent variation. Markerless computer vision may enable objective and repeatable locomotion monitoring under routine farm conditions. This study aimed to develop a 38-keypoint whole-body pose-estimation framework for automated dairy cattle lameness assessment and evaluate its agreement with blinded Sprecher locomotion scoring. Materials and Methods: A You Only Look Once version 8 (YOLOv8)-pose framework was developed using 12,000 annotated images obtained from 449 Holstein cows. Thirty-eight anatomical keypoints represented the head, spine, pelvis, forelimbs, hindlimbs, and hooves. Four model and input resolution configurations were evaluated. Joint-angle time series, coefficients of variation, and whole-body asymmetry features were derived from detected keypoints. For independent clinical validation, 120 cattle videos, obtained from animals with no overlap at the animal level with the 449-cow model-development cohort, were evaluated blindly by three assessors using the five-point Sprecher scale. Inter-observer reliability, consensus scores, rank associations, group differences, and exploratory receiver operating characteristic analyses were determined. Results: YOLOv8l-pose at 2560 × 2560 pixels showed the best performance, achieving pose mean average precision at an intersection over union threshold of 0.5 of 83.11%, mean average precision across thresholds of 0.5–0.95 of 37.39%, and recall of 91.74%. All three assessors assigned identical Sprecher scores to 87.5% of videos. Pairwise quadratic-weighted Cohen κ ranged from 0.843 to 0.926, Fleiss κ was 0.779, and intraclass correlation coefficients were 0.883 and 0.958 for single and average measurements, respectively. The continuous artificial intelligence (AI) score correlated significantly with consensus Sprecher scores (Spearman ρ = 0.234, p = 0.010), and score distributions differed among consensus groups (Kruskal–Wallis H = 13.09, p = 0.0014). Exploratory discrimination of consensus Sprecher scores ≥3, using a threshold internally derived from and evaluated within the same stratified validation cohort (not externally validated), yielded an area under the curve of 0.875; at an AI threshold of 2.9, sensitivity and specificity were 62.5% and 98.2%, respectively. Conclusion: The 38-keypoint whole-body model demonstrates technical feasibility as an anatomically comprehensive, sensor-free approach for quantifying dairy cattle locomotion. Because the clinical validation cohort was deliberately stratified and diagnostic thresholds were internally derived, its agreement with independent visual assessment should be interpreted as evidence of potential decision-support utility rather than established clinical performance. Prospective external validation and independent calibration of diagnostic thresholds in an unselected cohort are warranted before clinical or commercial deployment.

Only Look Once第8版（YOLOv8）-pose框架。38个解剖关键点代表头部、脊柱、骨盆、前肢、后肢和蹄部。评估了四种模型和输入分辨率配置。从检测到的关键点中提取关节角度时间序列、变异系数和全身不对称特征。为进行独立临床验证，由三名评估者使用五分制Sprecher量表对120头牛的视频进行盲法评估，这些动物在个体层面与449头模型开发队列无重叠。确定了观察者间可靠性、共识评分、秩相关、组间差异和探索性受试者工作特征分析。结果：2560×2560像素下的YOLOv8l-pose表现最佳，在交并比阈值为0.5时姿态平均精度为83.11%，在0.5–0.95阈值范围内的平均精度为37.39%，召回率为91.74%。三名评估者对87.5%的视频给出了相同的Sprecher评分。两两二次加权Cohen κ范围为0.843至0.926，Fleiss κ为0.779，单次测量和平均测量的组内相关系数分别为0.883和0.958。连续人工智能（AI）评分与共识Sprecher评分显著相关（Spearman ρ = 0.234，p = 0.010），且各共识组之间的评分分布不同（Kruskal–Wallis H = 13.09，p = 0.0014）。使用在同一分层验证队列内部推导并评估的阈值（未经外部验证），对共识Sprecher评分≥3进行探索性判别时，曲线下面积为0.875；在AI阈值为2.9时，敏感性和特异性分别为62.5%和98.2%。结论：38关键点全身模型表现","Veterinary
