当前我国农村合作经济组织还处于初级阶段,呈现发展速度慢、覆盖面窄、发展层次低、规模小等特点,所以畜牧业产业化组织形式仍以半紧密型的"龙头企业 养殖户"的模式为主.这种生产组织模式的特点是养殖户与龙头企业通过合同契约界定双方的权利与义务,养殖户按照契约约定进行指定品种和数量的畜产品生产,龙头企业按照契约约定专门从事畜产品的开发、收购、加工和销售,并为养殖户生产提供相应的服务. 相似文献

为探究绿色食品企业技术创新合作策略的影响因素,研究基于演化博弈理论,构造支付矩阵及演化博弈模型,并运用Matlab软件对演化模型进行数值仿真试验,对绿色食品技术合作创新策略选择进行演化博弈分析。结果表明：绿色食品企业合作策略受双方共同进行“开放式创新”策略的成本(I)和产出(R)、一方独自进行“开放式创新”策略的成本(C)和产出(E)及双方合作效益分配比例(k)的影响。在其他参数不变的情况下,I越高,双方选择“开放式创新,开放式创新”合作模式的可能性越高;I越低,双方选择“封闭式创新,封闭式创新”合作模式的可能性越高。R越高,双方选择“封闭式创新,封闭式创新”合作模式的可能性越高;R越低,双方选择“开放式创新,开放式创新”合作模式的可能性越高。C越高,企业选择“封闭式创新”策略的可能性越高;C越低,企业选择“开放式创新”策略的可能性越高。E越高,企业选择“开放式创新”策略的可能性越高;E越低,企业选择“封闭式创新”策略的可能性越高。当k取值为0.5时,双方选择“开放式创新,开放式创新”合作模式的可能性最高。鉴于此,对绿色食品企业提出关注行业技术创新现状,发挥龙头企业带头作用;积极运用外... 相似文献

青藏高原草地生态补偿博弈分析 总被引：1，自引：0，他引：1
草地生态补偿是一种恢复青藏高原退化草地、协调区域经济发展、保护草地生态屏障和解决社会公平的重要经济手段。然而,在实施草地生态补偿的过程中,政府与牧民和牧民与牧民之间的博弈会采取不同的博弈策略,只有在政府选择补偿和牧民选择保护的均衡策略时,才能解决政府与牧民博弈的"囚徒困境"问题;而解决草地生态补偿中牧民之间"智猪博弈"困局的关键是寻求一个集体利益最优的纳什均衡解。因此,只有在草地生态补偿中政府与牧民和牧民与牧民之间形成一种合作的均衡博弈,才能实现青藏高原草地生态系统的可持续发展。 相似文献

在公共文化服务设施的建设中,政府、民间资本和创业者的价值取向是矛盾的,三方不可能自动走向合作博弈的Pareto最优.在对“政产资”三方双行动序贯博弈进行分析的基础上,构建“三方结合＋民资先行＋民政测试代理”的协同合作模式对三方的关系进行协调,以降低三方之间的信息不对称,并用曲江池模式进行验证. 相似文献

A survey of the management of mixed farming of cattle and antelope and use of anthelmintics was conducted on eleven farms between August and December 1999 by a self-administered questionnaire. Seventeen antelope species ranging from grey duikers (Sylvicapra grimmia) to eland (Taurotragus oryx) occurred on the farms. Impala (Aepyceros melampus) was the most abundant antelope on the farms. Seventy-five per cent of the antelope species on the farms were grazers and mixed feeders and shared grazing with cattle. Most farmers (n = 8) did not consider the stocking density for cattle and antelope as an important management factor. Fifty-four per cent of the farmers (n = 6) routinely dewormed both cattle and antelopes. Albendazole and fenbendazole were the most commonly used drugs for deworming cattle (72.7%) and antelope species (54.5%). The deworming of antelope was carried out during the dry season, using albendazole-, fenbendazole-and rafoxanide-medicated supplementary feed blocks. Doramectin injections were given to antelopes on two farms. Cattle were dewormed preventively and according to the general body condition of the animal. Few farmers (n = 4) followed the recommended deworming programme for cattle in Zimbabwe and only one farmer followed a specified dosing programme for game. However, results from the survey on the deworming of game indicate that farmers perceived helminth infections in antelope to be important. 相似文献

Small game involves numerous infection hazards in terms of contact zoonoses and foodborne diseases. Especially exposed are hunters, game dealers, veterinarians, housewives, farmers, forest workers, laboratory staff, and taxidermists, but also consumers of insufficiently cooked game. This paper gives a survey of the most significant zoonoses in small game in Europe, which are discussed in the light of the author's own research results in this field. Finally, measures concerning prophylaxis and food hygiene are suggested. 相似文献

Tick control methods used by resource-limited farmers and the effect of ticks on cattle in rural areas of the Eastern Cape Province,South Africa 总被引：1，自引：1，他引：0
A survey to document tick control methods used by resource-limited farmers in the control of cattle ticks in the Eastern Cape
Province of South Africa was conducted by interviewing 59 cattle farmers using structured questionnaires and general conversation.
Information collected was on external parasites of cattle, their effects and their control methods. Ticks were reported to
be a major problem causing diseases like anaplasmosis (89.8%), babesiosis (55.9%) and ehrlichiosis (16.9%), as well as wounds
that predispose to screwworm infestation, tick worry and teat damage to cows troubling farmers in their farming enterprises.
The main tick control methods were; acaricides provided by government, however 94.9% of the farmers interviewed were of the
opinion that the dip wash is not effective in killing the ticks. As a result, farmers complement the government dipping service
with their own initiatives like spraying with conventional acaricides (22%), household disinfectants such as Jeyes fluid (18.6%),
used engine oil (10.2%), chickens (5.1%), manual removal (5.1%), and pouricides (1.7%). In addition, some farmers also use
plants (6.8%), mainly the leaf of Aloe ferox and the bark of Ptaeroxylon obliquum. The study revealed ticks to be a major problem in the study area. 相似文献

A study was conducted in Rukomo sector, Nyagatare district, to determine the status of poultry production. A structured questionnaire was used to collect data from 100 poultry farmers randomly as 20 farmers from each of the five cells. Data were analyzed using SPSS version 16 and presented in chart and tables. The majority of the farmers (84%) reared their poultry in free range system while 10% practiced semi-intensive and only 6% did intensive production. Only 12% of the respondents kept exotic poultry breeds. The breeding stock were mostly obtained from local markets (63%) and the average flock size was about 1–10 birds per homestead (70%). The confinement of poultry at night was either in the main domestic house (33%), in kitchen (32%), or in separate poultry house (35%). Flock records were rare and kept by only 9% of respondents. Poultry products were reportedly at high demand by 87% of respondents and 89% farmers reported profit from their enterprises. Lack of veterinary and financial assistance was reported by 72% of respondents. Newcastle disease (57%) was the main health constraint followed by ectoparasites and internal worms. Many farmers (50%) were in dire need of veterinary assistance and financial support to improve their poultry enterprises. Poor management practices were reported to be one of the crucial factors leading to poor production. Lack of quality feeds (38%) and feeding of poultry, credit (20%), and poor market accessibility (19%) were the main challenges reported. 相似文献

内蒙古清水河县肉驴产业发展现状与展望 《畜牧与饲料科学》2018,39(12):98-102
通过召开座谈会、实地走访调查、填写问卷等方式收集材料和数据,调研内蒙古清水河县肉驴产业发展背景、现状,并分析了该县肉驴养殖企业的收支情况。结果表明,清水河县自然条件适合发展肉驴养殖业,并且肉驴养殖企业的入驻和发展,带动了当地农户养殖肉驴的积极性,也给产业扶贫带来了新启示。但是,该县肉驴产业的发展尚处于初期,再加上自然条件的约束以及路、水、电、通信网络建设的落后,以及肉驴养殖服务体系的不健全等原因降低了肉驴养殖企业的收入;散户肉驴养殖技术和经营方式停留于传统的方式,制约着产业的发展。针对以上问题提出了健全和完善农企利益联结机制、采取“公司+合作社+基地+农户”的养殖模式、创建休闲与观光旅游业相结合的肉驴产业发展体系的对策建议,以期为清水河县科学发展肉驴产业提供参考。 相似文献
