现今养猪业需要规模化和现代化的生物安全系统作保障,建立健全的生物安全体系可有效预防猪群一系列传染病的发生,这对猪群的健康有重要影响。在猪场各种传染病肆虐的环境下,如何在实际生产中完善生物安全体系的建设,是当前养猪生产面临的重要问题。文章针对目前猪群中流行疾病在临床实践调查中优化病原体检测的方法,对生物安全实施的内部对象建立完善生物安全体系做出相关建议指导。 相似文献

规模化猪场生物安全体系建设 总被引:4,自引:2,他引:2
正猪场生物安全体系指通过有效践行"消灭传染源、切断传播途径、保护易感猪群"三条基本原则,正确评估猪场面临的疫病风险,并据此制定出一系列有效的预防和管控措施的一种综合性的疫病防控体系。近年来,很多规模化猪场因在生物安全管理方面出现漏洞,导致猪群健康水平低下,猪场效益不佳,教训深刻。因此,做好规模化猪场生物安全体系建设,可以有效保障猪群健康,降低造肉成本与提升生产性能。1猪场选址与布局猪场选择要遵循生物安全原则,需要有良好的隔离条件,因此场址应选择远离居民区、交通主干道、屠宰场等疾病风险较高的区域,猪场应建立在地势 相似文献

猪场生物安全管理是完善的猪场疫病防控体系,是在实践基础上总结出来的优化的、全面的用于生猪生产和疫病防控的系统工程,是以切断传播途径为主、预防猪疫病发生的生产管理体系。主要包括用来避免病原体进入猪群或猪场的外部生物安全和当病原体已存在时防止疫病在猪群内或猪场内向未感染猪散布或向其他猪场散布的内部生物安全。加强猪场生物安全管理是实现疫病控制、净化的重要途径。当前,非洲猪瘟、猪瘟、伪狂犬病、猪繁殖与呼吸综合征的控制和净化是我国猪病防控的重中之重,必须依靠严格的猪场生物安全体系建设以及疫苗的强化免疫,同时配合科学的监测才能实现有效控制和净化。 相似文献

2018年8月开始,非洲猪瘟在我国快速多点发生,该病是高度接触性传染性疾病,目前无有效的疫苗和药物控制,各大公司和养殖户开始了猪场生物安全体系的升级改造。两年后我国大部分猪场的成功复产,全国生猪出栏量的大幅提升,证明了生物安全措施巨大效力;同时在严格的生物安全措施下创新了精准剔除、快速复产等操作,进一步证明了生物安全措施的有效作用。文章主要介绍猪场生物安全体系中入口(大门)和出口(后门)最为关键防线处的通道设计,方便所有的生物安全操作能够高效落实,切断病原轻易进出猪场的途径。 相似文献

Multivariate analysis of management and biosecurity practices in smallholder pig farms in Madagascar 总被引:1,自引:0,他引:1

A cross-sectional study was carried out in 2005 and 2006 in three geographical areas of Madagascar to investigate and differentiate swine farm management and biosecurity practices in smallholder farming communities. Questionnaire data from a total of 709 pig farms were analysed using multiple factor analysis (MFA) and hierarchical cluster analysis (HCA). Variables describing management and biosecurity practices were organised into five groups: structure of the farm, animal-contacts, person- and vehicle-contacts, feeding, and sanitary aspects. In general, few biosecurity measures were implemented in the pig farms included in the study. Regional differences in management and biosecurity practices emerged from the MFA and were mainly due to, in order of decreasing importance: structure of the farm, sanitary aspects, feeding and animal-contacts and, to a lesser extent, person- and vehicle-contacts. HCA resulted in the differentiation of four distinct types of farms in each of two study areas, Arivonimamo and Marovoay, while no grouping could be identified amongst farms in Ambatondrazaka area. The characterisation of the different types of smallholder pig farms will allow adapting recommendations on husbandry practices and control measures in pig farms of these regions of Madagascar. The development of tailored recommendations is essential for Malagasy smallholders who have limited resources and need to make evidence-based management changes to reduce the risk of contagious diseases in their herds. 相似文献

In Uganda, a low-income country in east Africa, African swine fever (ASF) is endemic with yearly outbreaks. In the prevailing smallholder subsistence farming systems, farm biosecurity is largely non-existent. Outbreaks of ASF, particularly in smallholder farms, often go unreported, creating significant epidemiological knowledge gaps. The continuous circulation of ASF in smallholder settings also creates biosecurity challenges for larger farms. In this study, an on-going outbreak of ASF in an endemic area was investigated on farm level, including analyses of on-farm environmental virus contamination. The study was carried out on a medium-sized pig farm with 35 adult pigs and 103 piglets or growers at the onset of the outbreak. Within 3 months, all pigs had died or were slaughtered. The study included interviews with farm representatives as well as biological and environmental sampling. ASF was confirmed by the presence of ASF virus (ASFV) genomic material in biological (blood, serum) and environmental (soil, water, feed, manure) samples by real-time PCR. The ASFV-positive biological samples confirmed the clinical assessment and were consistent with known virus characteristics. Most environmental samples were found to be positive. Assessment of farm biosecurity, interviews, and the results from the biological and environmental samples revealed that breaches and non-compliance with biosecurity protocols most likely led to the introduction and within-farm spread of the virus. The information derived from this study provides valuable insight regarding the implementation of biosecurity measures, particularly in endemic areas. 相似文献

Chile eradicated classical swine fever (CSF) in April 1998, following a 17-year eradication programme. The authors describe biosecurity levels of pig farms in Chile after the eradication of CSF. A formal survey was administered to 50 large integrated pig farms, which represented almost 60% of the swine population. The main topics on the questionnaire were production, health management, biosecurity, insurance and information about CSF outbreaks in the past. Biosecurity practices were analysed according to the criteria stated by Barcelo and Marco in 1998. A scoring system to measure biosecurity was designed and pig farms were classified according to this score. An adjusted specific measure is discussed as a potential indicator of risk for disease infections. The authors explore associations between biosecurity herd size and insurance policy against CSF. 相似文献

传统的养猪模式难以应对诸如非洲猪瘟这样的疫病,普通平层猪场叠加而成的楼房没有从本质上得到改进,而结构创新之后的楼房猪场在养猪的可靠性上大大增强,并可能发展为城市养猪新模式,为防非保猪、稳产保供提供一种解决方案。在此基础上升级的"料、养、宰、商一体化"造肉工厂模式,更是一种能把运猪变为运肉的可行解决方案。当这些模式得到应用和推广时,困扰行业的"猪周期"问题也将得到妥善解决。 相似文献
