非洲猪瘟影响下的猪场生物安全措施

非洲猪瘟是一种具有高度接触性、烈性和急性传染病,具有发病率和死亡率高的特点,目前尚无有效疫苗治疗。非洲猪瘟最有效的防治方法是早期确诊、封锁隔离、规模捕杀。非洲猪瘟关系整个猪肉市场的供应和行业的发展,因此,在当前严峻形势下,强化猪场生物安全显得尤为迫切和重要。     

非洲猪瘟对益阳市生猪生产的影响及对策

非洲猪瘟发生以来,对益阳市生猪生产的影响很大。主要表现为:生猪产能快速下降、养猪者信心缺失、猪肉消费持续下降和供需缺口加大等形式,笔者从提高思想认识、明确主体责任、加强检验检疫和加大市场监管等方面进行建议,为行业主管部门全面恢复和稳定生猪生产提供理论依据。     

非洲猪瘟疫情背景下我国生猪保险发展现状、功能作用及对策建议探讨

生猪产业是农业生产的重要组成部分,是农民收入的重要来源之一,猪肉也是我国城乡居民的主要副食品。2018年8月,我国暴发非洲猪瘟疫情,非洲猪瘟对我国生猪产业造成了较大影响,猪肉产能迅速下降,猪肉价格持续上涨。发展生猪保险,是落实国家扶持生猪生产政策的重要举措,有利于帮助农户分散转移风险,调动养猪积极性,推动农民增收;有利于提高生猪产业防灾防疫能力,稳定生猪市场供应,保障人民生活;有利于充分发挥保险的社会管理功能,助力国家乡村振兴战略。文章首先简要介绍了我国生猪保险业务发展现状,包括业务规模、保险产品情况及存在问题等,在此基础上结合生产实际情况,对非洲猪瘟背景下我国生猪保险对生猪稳产保供的功能作用进行了详细分析,包括经济补偿、价格稳定、风险管理、融资增信、社会治理和产业扶贫等六大方面。虽然我国生猪保险业务发展取得了较好成效,但仍面临着业务覆盖率偏低、道德风险高、市场化保费费率定价缺乏等难题,所以文章在最后提出了推进我国生猪保险稳定健康发展的相关建议。

沙子岭猪肥育性能与肉质特性研究

本试验选择16头沙子岭纯种仔猪,随机分成二组,分别饲喂不同能量、蛋白水平的日粮,探讨营养水平对沙子岭猪肥育性能与胴体品质性状的影响.结果表明低水平和高水平组日增重分别为411.38 g、 445.75 g,差异不显著(P＞0.05);饲料报酬分别为4.82∶1、 4.48∶1;每公斤增重饲料成本分别为6.60元、 6.54元;胴体瘦肉率分别为44.59%、 40.82%,差异不显著(P＞0.05).与国内地方猪种比较,沙子岭猪具有生长速度较快、屠宰率较高、眼肌面积较大、背膘较薄、瘦肉率较高的特点.     

非洲猪瘟背景下的保育猪疫病防控策略

非洲猪瘟是一种急性、热性高致死性的动物传染病,该病是2018年8月新传入我国的强行传染病危害极大,已被我国列入重要控制病种.本文结合我国各地的实际防控经验,将非洲猪瘟下保育猪疫病的防控策略概述如下.     

非洲猪瘟背景下生猪供应链重塑及其对策研究

2018年8月初我国首次发现非洲猪瘟疫情,其后有多个省份相继爆发疫情。虽然非洲猪瘟疫情在我国处于总体可控状态,但也对生猪产业产生了重要影响。限制生猪长途调运是防止非洲猪瘟疫病传播的重要手段,也是产业发展的必然趋势。相对于以往大规模的活猪运输,猪肉的调运很大程度上需要重塑供应链。供应链中的生猪屠宰、冷库储藏、运输等关键环节都必须做出调整。为此,本文梳理了非洲猪瘟背景下从调猪到调肉供应链重塑的关键节点,并提出相关的对策建议。     

非洲猪瘟及禁抗背景下提高猪只免疫力的思考

非洲猪瘟（ASF）是由非洲猪瘟病毒（ASFV）引起的一种的热性、斑疹性、高度接触性的猪传染病。世界首例ASF于1909年在非洲肯尼亚被发现。由于其传染性强,且发病后致死率高,给生猪养殖带来极大的危害,且严重影响了畜牧经济的发展。特别是在全球禁抗背景下,提高猪只免疫力成为防控ASF的重要环节。文章就ASF特征、临床表现,就如何在禁抗下提高猪免疫力提出一些建议。     

Neutralization of African swine fever virus by sera from African swine fever-resistant pigs

Sera from African swine fever-resistant pigs with infection-inhibitory activity decreased virus replication in infected porcine buffy coat cultures. This same effect was observed even after virus was adsorbed. The infection-inhibition was not reversed by removing the immune serum from the assay cultures. Reduction of African swine fever virus replication by immune sera was demonstrated by fluorescent focus assay on MS cell line cultures. Virus-neutralization tests showed a persistent fraction of non-neutralized virus, which was not demonstrable by infection-inhibition tests. One hypothesis for explaining this difference is proposed.     

非洲猪瘟疫情形势下生长育肥猪饲养管理关键技术

育肥猪的科学饲养与管理直接影响猪场经济效益,非洲猪瘟疫情形势下的育肥猪生产更是充满挑战与压力。文章旨在针对生长育肥猪养殖的基本环节及操作要点,从环境控制、科学饲养与管理、严格防疫等方面阐述了育肥猪养殖的关键技术,为非洲猪瘟疫情防控形势下的生猪保供复产提供技术支撑。     

浅谈非洲猪瘟背景下的后备母猪初配标准和改善措施

非洲猪瘟进入我国已2年有余,目前全国生猪产能已经恢复到非瘟发生前的88％以上.但是,猪场在快速恢复产能过程中诸多问题会对猪场生产成绩造成持续影响,例如如何确立后备母猪初配标准,亟待建立和规范.文章从后备母猪初配标准的重要性、关键指标和改善措施3个方面进行深入剖析和探讨,旨在为猪场建立最佳的后备母猪初配条件提供参考.     

Comparative evaluation of novel African swine fever virus (ASF) antibody detection techniques derived from specific ASF viral genotypes with the OIE internationally prescribed serological tests

The presence of antibodies against African swine fever (ASF), a complex fatal notifiable OIE disease of swine, is always indicative of previous infection, since there is no vaccine that is currently used in the field. The early appearance and subsequent long-term persistence of antibodies combined with cost-effectiveness make antibody detection techniques essential in control programmes. Recent reports appear to indicate that the serological tests recommended by the OIE for ASF monitoring are much less effective in East and Southern Africa where viral genetic and antigenic diversity is the greatest. We report herein an extensive analysis including more than 1000 field and experimental infection sera, in which the OIE recommended tests are compared with antigen-specific ELISAs and immuno-peroxidase staining of cells (IPT). The antibody detection results generated using new antigen-specific tests, developed in this study, which are based on production of antigen fractions generated by infection and virus purification from COS-1 cells, showed strong concordance with the OIE tests. We therefore conclude that the lack of success is not attributable to antigenic polymorphism and may be related to the specific characteristics of the local breeds African pigs.     

Swine fever: classical swine fever and African swine fever.

Because of the clinical and pathologic similarity to common endemic diseases, introduction of CSFV or ASFV strains of moderate to low virulence represents the greatest risk to North American swine herds. Producers, veterinarians, and diagnosticians should increase their awareness of these devastating diseases and request specific diagnostic testing whenever they are suspected. Production practices that improve biosecurity will reduce the risk of introduction of CSF and ASF and limit the spread if an incursion occurs. Additional resources. The following Web sites contain excellent color photographs that will assist producers and practitioners in identifying clinical signs and gross lesions associated with CSFV and ASFV: http://www.vet.uga.edu/vpp/gray_book/FAD and http://www.pighealth.com. The latter Web site and the OIE Web site (http://www.oie.int) offer updated information on current worldwide epizootics of ASF and CSF and other swine diseases. Details of biosecurity procedures can be found at http://www.agebb.missouri.edu; see publication G2340.
