上海市犬只狂犬病认定免疫点主要管理做法分析

强化犬只狂犬病免疫工作是从源头控制狂犬病的最有效措施。近年来,上海市按照《上海市养犬管理条例》的要求,通过严把免疫资质准入、规范内部管理、落实疫情报告责任、推进免疫质量考核等举措,使犬只狂犬病认定免疫点的布局日趋合理,文明服务更加规范,这已成为上海市民犬只狂犬病免疫的主渠道,免疫数量和质量逐年提升,构筑了良好的免疫屏障。今后在犬只狂犬病认定免疫点管理方面,上海市应强化疫苗源头管理,加大非法免疫惩处力度,合理认定免疫点整体布局,规范引导免疫行为和内部运行。     

A proposal to leverage high-quality veterinary diagnostic laboratory large data streams for animal health,public health,and One Health

Test data generated by ~60 accredited member laboratories of the American Association of Veterinary Laboratory Diagnosticians (AAVLD) is of exceptional quality. These data are captured by 1 of 13 laboratory information management systems (LIMSs) developed specifically for veterinary diagnostic laboratories (VDLs). Beginning ~2000, the National Animal Health Laboratory Network (NAHLN) developed an electronic messaging system for LIMS to automatically send standardized data streams for 14 select agents to a national repository. This messaging enables the U.S. Department of Agriculture to track and respond to high-consequence animal disease outbreaks such as highly pathogenic avian influenza. Because of the lack of standardized data collection in the LIMSs used at VDLs, there is, to date, no means of summarizing VDL large data streams for multi-state and national animal health studies or for providing near-real-time tracking for hundreds of other important animal diseases in the United States that are detected routinely by VDLs. Further, VDLs are the only state and federal resources that can provide early detection and identification of endemic and emerging zoonotic diseases. Zoonotic diseases are estimated to be responsible for 2.5 billion cases of human illness and 2.7 million deaths worldwide every year. The economic and health impact of the SARS-CoV-2 pandemic is self-evident. We review here the history and progress of data management in VDLs and discuss ways of seizing unexplored opportunities to advance data leveraging to better serve animal health, public health, and One Health.     

北京市规模化奶牛场运动场防雨现状及建议

运动场是保障奶牛生产力和动物福利的重要设施。2021年6—9月,频繁降雨导致北京地区多家奶牛场的运动场积水,为奶牛生产力、奶牛场生防安全、环境卫生、运动场舒适性和动物福利带来隐患。通过线上线下结合,调研了北京地区27 家规模化奶牛场的运动场防雨、排水及垫料现状。结果表明：调研奶牛场中,88.90%奶牛场配备了运动场,其中83.33%奶牛场通过设置地面倾角、设置挡雨棚、雨污分离槽及布设排水管道（沟渠）、雨后水泵排水等方式实现运动场防雨及排水。此外,针对运动场建设、运动场防雨、运动场舒适性展开讨论,以期改善运动场防雨现状,满足集约化奶牛场可持续发展需求和提升动物福利。     

犊牛饮水的重要性与管理要点

犊牛阶段的生长发育状况对成年后生产性能的发挥具有极为重要的影响,所以犊牛的饲养管理非常关键。水是犊牛维持基础营养代谢和健康生长的重要营养元素,但是与代乳粉和开食料等日粮相比,容易被牧场忽视。本文分析了犊牛饮水的重要性及需水量与采食量的关系,讨论了犊牛饮水管理中的关键点,为加强犊牛饮水管理,提高犊牛阶段的培育管理水平提供指导。     

自动化饲喂饲养模式下哺乳犊牛的饲养管理

犊牛是牧场发展的后备军,优质的犊牛培育是牧场可持续发展的有利保障之一。因此,科学的犊牛饲养管理措施和合理的犊牛饲养模式对于犊牛培育极其重要。通过对自动化饲喂饲养模式下哺乳犊牛的饲喂技术、管理措施以及疾病预防等方面进行综述,重点介绍初乳、饲喂计划、补饲、奶粉及开食料、饲喂标准、饲养环境、管理细节差异、疾病治疗方案等内容,以期对自动化饲喂饲养模式下的牧场提供参考。     

洛阳生生牧业犊牛健康管理经验

近年来,牧场逐步走向现代化、规模化发展,生产水平大幅度提高,后备牛的培育也提升到了新的高度。犊牛健康管理是牧场成败的关键,但如何做好犊牛健康管理,成为制约奶牛业健康发展的瓶颈之一。为此,本文对河南洛阳生生牧业有限公司的犊牛健康管理工作进行了认真总结,旨在了解犊牛管理现状,分析存在的问题,探索适合大型牧场应用的犊牛管理模式,促进奶业健康、可持续发展。     

奶牛场温室气体排放与减排措施

奶牛养殖在产能提升的同时也排放了大量温室气体。本文梳理了奶牛养殖场温室气体排放的重点环节,主要分为奶牛养殖活动温室气体排放以及牛场日常运行耗能两个方面;结合奶牛养殖肠道发酵和粪污管理的温室气体核算方法,归类整理了主要的减排措施,包括进行提高饲料质量和转化效率、粪污高效管理、清洁能源替代等方式,助力奶牛养殖实现低碳乃至零碳排放。     

奶牛围产期饲养管理要点

奶牛围产期的饲养管理是规模化奶牛场生产环节中的重中之重,该项工作不仅影响奶牛泌乳量和生鲜乳品质,还直接决定新生犊牛的健康水平和奶牛的产后恢复情况。因此,各牧场需要加强奶牛围产期的饲养管理,让奶牛在分娩前后平稳过渡。本文从营养需要、分群、饲养和环境等方面介绍了奶牛围产前期和围产后期的管理需要,以期为围产期奶牛的科学饲养管理提供理论参考。     

Carbon Depletion by Plowing and its Restoration by No‐Till Cropping Systems in Oxisols of Subtropical and Tropical Agro‐Ecoregions in Brazil

The continuous use of plowing for grain production has been the principal cause of soil degradation. This project was formulated on the hypothesis that the intensification of cropping systems by increasing biomass‐C input and its biodiversity under no‐till (NT) drives soil restoration of degraded agro‐ecosystem. The present study conducted at subtropical [Ponta Grossa (PG) site] and tropical regions [Lucas do Rio Verde, MT (LRV) site] in Brazil aimed to (i) assess the impact of the continuous plow‐based conventional tillage (CT) on soil organic carbon (SOC) stock vis‐à‐vis native vegetation (NV) as baseline; (ii) compare SOC balance among CT, NT cropping systems, and NV; and (iii) evaluate the redistribution of SOC stock in soil profile in relation to soil resilience. The continuous CT decreased the SOC stock by 0·58 and 0·67 Mg C ha⁻¹ y⁻¹ in the 0‐ to 20‐cm depth at the PG and LRV sites, respectively, and the rate of SOC sequestration was 0·59 for the PG site and ranged from 0·48 to 1·30 Mg C ha⁻¹ y⁻¹ for the LRV site. The fraction of C input by crop residues converted into SOC stock was ~14·2% at the PG site and ~20·5% at the LRV site. The SOC resilience index ranged from 0·29 to 0·79, and it increased with the increase in the C input among the NT systems and the SOC sequestration rates at the LRV site. These data support the hypothesis that NT cropping systems with high C input have a large potential to reverse the process of soil degradation and SOC decline.
