法国猪场采用EFS系统 法国一座可容纳250头妊娠母猪的新猪场目前正式投产使用.该猪场规模为400头基础母猪.新建妊娠猪舍采用稻草垫料群养的生产方式.该猪舍采用自然通风,在漏缝地板上装备有5个Nedap Velos自动喂料器.这些喂料器与中央隔离单元相结合,对舍内面积进行了明确分区.这样不仅能够降低应激水平,而且还能鼓励母猪在有限的、专门的区域排粪.该猪舍配备自动发情检测系统,持续观察母猪对公猪的反应.母猪行为发生变化的时候会进行分析,适当的时候会发出发情指示. 相似文献

笔者参加了为期一年的美国内布拉斯加州仔猪繁育专场研修,努力学习美国先进猪场管理经验。现将其整理成文,供行业内同事朋友参考,请批评指正。大型猪场通过自动控制系统进行饲料投喂和猪舍室温控制。美国人力成本较贵,该场很早就采用自动控制系统,通过多年的设备更新和完善,整套系统运转良好。一、喂料系统为保持高效和精确的饲料投喂,一般大型猪场都通过自动喂料系统进行饲料的投喂。笔者所在的仔猪繁 相似文献

美国、澳大利亚家禽食品安全管理体系的发展及启示 总被引：1，自引：0，他引：1
家禽食品安全对家禽业发展至关重要,因此研究和借鉴发达国家家禽食品安全的管理、控制体系对我国制定家禽食品安全法规、规范企业行业生产具有重要意义。目前,相关研究主要集中在食品安全方面,但从家禽角度研究发达国家与中国食品安全对比的报道不多。中国家禽食品安全管理从养殖、屠宰加工、储藏运输、零售批发等方面均与国际发达国家有较大差距,未来中国家禽食品安全管理体系的发展应该从这4个方面入手制定相应法律法规,加强监控管理,完善产业体系。 相似文献

我国高校危机管理状况不容乐观,高校危机事件时有发生。目前高校危机管理存在的问题主要表现为：危机意识淡薄、缺乏专门常设的危机管理机构、缺乏制度化和系统化的应对机制,即高校普遍缺乏应对危机的制度性平台和应急管理规则。因此,建构危机管理体系是当前高校亟待解决的一个重要问题。高校危机管理体系的建构包括组织机构的设置、危机决策机制的建立、危机沟通机制的建立和危机控制机制的建立等四个方面。其中组织机构是基础,决策机制是关键,沟通机制是桥梁,控制机制是核心,四者自成一体又相互联结,共同构成一个完整的高校危机管理体系。 相似文献

试论青藏高原草业系统生态危机主要成因及对策 总被引：4，自引：1，他引：3
草业系统是青藏高原生态系统大惊讶时空异质景观，是该区域的生命支持系统，气候生态因子主导性、大尺度时空相悖性和灰色属性是青藏高原草业系统的显著特征。草业系统通过自身适应机制，调控来自地境及其它系统的胁迫，从而实现脆弱的动态平衡。生态危机症状发生在青藏高原草业系统的3个界面：牧草－－地景界面、草地－－动物界面、草畜－－经营管理界面。疏探经营管理是青藏高原草业系统生态危机的发动机和催化剂，可以用经营者－－投入等多方面无序，构建新的经营管理系统是遏制生态危机、恢复生态平衡的根本出路。 相似文献

The use of remote sensing and geographic information systems in UNICEF's dracunculiasis (Guinea worm) eradication effort 总被引：1，自引：0，他引：1

Dracunculiasis (Guinea worm disease) is a parasitic disease which is endemic in 18 African and two Asian countries. It has a marked potential for eradication by a combination of water supply management, health education and controlled medical intervention. While data on the disease are, in many cases, both in short supply and unreliable, increasingly the tools of remote sensing and geographic information systems (GIS) are becoming important components of the eradication effort. In particular, remotely sensed data from LANDSAT have allowed the identification and location of remote and small settlements in dracunculiasis-endemic areas. When coupled with additional information available in remotely sensed data from LANDSAT, and when used in conjunction with a GIS containing digitized maps and field data collected from hand-held global positioning system receivers, the eradication effort has developed an epidemiological tool of potential power. While at first this system is finding uses in managing existing data in a unified inventory, the system shows potential for use as an effective management decision-making tool as the control effort moves from disease reduction to disease eradication. This paper will use a single province within one country, the Zou Province of Benin, to demonstrate the varied data sources involved in the system, the software and hardware components of the system, and to discuss the specific problems involved in using the system in the field. Of particular consideration, and of potential use to other similar programs, is a consideration of the management and implementation of the system. The paper concludes that a combination of remote sensing and GIS technologies offers the epidemiologist a new and important means by which to effectively implement solutions to public health management problems. 相似文献

We examine how the system of grazing management of cattle in savanna rangelands affects the herd response to drought. We have used long-term time series data to evaluate the effects of management on drought-induced cattle mortality using traditional livestock management practices. There was no control of stocking densities, as compared to a government ranch where stocking densities would be adjusted in accordance with available pasture. We tested the responses under two scenarios. Scenario 1: Response of cattle herds to inter-annual rainfall variability (IRV) under a regulated grazing management system; this provides more reliable predictions of cattle population and performance in terms of herd mortality and calving rates than does the communal land use system. Scenario 2: Regardless of the management system, similar trends in cattle populations will be observed in response to IRV. The results of the study showed that fluctuations in cattle numbers, herd mortality and calving rates were highly correlated with IRV, with stronger linear impacts in accordance with scenario 2. In both management systems, cattle herd sizes and calving rates declined during periods of drought, followed by slow recovery. Cattle populations in Borana rangelands in southern Ethiopia did not recover for a period of two decades. We conclude that a management system based on control of stocking densities did not improve herd survival, as compared with traditional drought management strategies. This contradicts common expectations. Increased drought frequencies aggravated cattle mortality and lowered calving rates. The implication of the findings is that regardless of adjusted stocking density, livestock populations in the arid savanna ecosystems of southern Ethiopia remain at risk from climate change. 相似文献

From 1992 to 1995, 0.15% (n=3916) of the bovids (cattle and buffalo) in Sri Lanka were sampled, using a multi-stage sampling procedure. Serum antibodies for Brucella abortus were detected using the indirect enzyme-linked immunosorbent assay (ELISA). The age, the agroecological zone and the management system practiced in the farms of the sampled bovids were studied as risk factors for seropositivity.The overall seroprevalence of brucellosis in cattle was 4.7% (n=3076) and 4.2% in buffaloes (n=840). Bovids that were over 3 years of age, from the dry zone (annual rainfall 20-35 in.), and reared under an extensive management system had higher odds of being seropositive. Bovids from the dry zone were at approximately six times higher odds of being seropositive even after controlling for the possible effects of age and management system. Approximately 75% of the seropositive males were from the dry zone. Most bovids (84%) from the dry zone in this study were reared under an extensive management system (free grazing) which allows unrestricted contact between animals. These factors may have contributed to the spread of brucellosis in bovids in the dry zone.This infection might be an important cause of abortion in bovids in Sri Lanka. However, there is also evidence of other causes for abortion, repeat breeding and retained placenta. 相似文献
