为解决柑橘种苗假冒、套牌等侵犯知识产权纠纷频繁、举证困难等问题,课题组前期基于射频识别（RFID,Radio Frequency Identification）技术研发了一套由硬件与管理软件组成的身份溯源系统,本研究分别对电子芯片、阅读器、植入枪 3 个硬件进行了信号强度、稳定性及植入效率的功能测试,并介绍了软件系统实现的途径。结果表明,电子芯片在9mm至63mm的茎粗中均能被识别;阅读器在测量距离≤10cm的范围内识别成功率为100%;植入枪的效率达到4枚/min。三项硬件设备功能完备,电子芯片信号强,阅读器稳定性好,植入枪的效率及精准度远高于其他植入工具。身份溯源系统的开发为果茶等多年生作物种苗的知识产权保护提供了新思路。 相似文献

A total of 351 Iberian pigs with equal numbers of both sexes from 2 commercial farms were used to study the ability of various identification devices to guarantee the traceability required for labeled meat products from Iberian pigs reared under extensive production conditions in Spain. The performance of tattoos, visual ear tags, electronic ear tags, and i.p.-injected transponders of half duplex and full duplex technologies were compared during a production cycle from nursery to slaughter at 15 mo of age (156 +/- 3 kg of BW). No major health reactions to any of the identification methods were detected. Results showed that tattooing was not an adequate identification procedure due to reading difficulties as a consequence of dark skin, soiled appearance, and figure deformation. Ear tag losses and failures were affected by fencing type and increased in one of the farms (20.4 and 15.7% for losses and failures, respectively; P < 0.05) as a consequence of using barbed-wire fences. Ear tag losses decreased when fences changed to stone blocks at 365 d of age. Visual and electronic ear tag losses during transport and slaughter were low (3.7% for visual and 3.1% for electronic tag). Results of injectable transponders during the growing-fattening period were variable and were more readable for the half duplex than for the full duplex i.p. transponders (92.0 vs. 68.7% +/- 1.5; P < 0.05). Handheld transceivers worked properly under extensive conditions, although the body size and skin characteristics of the Iberian breed might limit the performance of reading devices, and the use of transceivers with longer reading distances is recommended. The main problem observed with i.p. transponders was their low recovery rate at slaughter due to the lack of adherence of the transponders to the omentum. 相似文献

Lifetime traceability of weaner pigs in concrete-based and deep-litter production systems in Australia 总被引：2，自引：0，他引：2

A field study was conducted on a 2,300-sow piggery in southwestern New South Wales, Australia, over a 17-wk period (from weaning at 4 wk of age) to assess the suitability for lifetime traceability of weaners of 4 identification devices: 1) full duplex ear tag (FDX, Allflex), 2) half duplex ear tag designed for cattle (HDX, Leadertronic), 3) conventional ear tag (Leader), and 4) ear tattoo (Ketchum ear tattoo 101). Visual readability, retention rate, electronic failures, and adverse side effects were assessed at 8 wk after application at both sites and before slaughter at 14 or 17 wk after application at site A and site B, respectively. A total of 394 weaner pigs were randomly assigned after weaning to 6 treatment groups and reared either in small groups in intensive, indoor, concrete-based pens (n = 224; site A) or in a large group on deep litter (n = 170; site B). Visual readability was similar for all ear tag types before slaughter (P > 0.05); however, visual readability of the ear tattoo was lower (P < 0.05), with between 78.2 and 60.0% illegible due to ink fading. Few tags were lost in the 8-wk period after application; however, tag loss increased for each tag device after this period and varied with housing system. Conventional tag loss was greater among pigs housed at site A (29.0%) than in pigs housed at site B (4.9%) in the 6- to 9-wk period before slaughter. The overall readability of FDX and HDX tags did not differ (P > 0.05) between sites; however, overall readability of FDX tags at 98.4% was better (P < 0.05) than 71.8% for HDX tags. Tag costs ranged from $0.73 for the conventional ear tag to $2.42 for the HDX ear tag. The identification devices did not induce production-limiting adverse effects after they were applied. Under conditions of this study, FDX electronic ear tags were the most efficacious for lifetime identification of weaner pigs on-farm. 相似文献

智慧养猪已成为生猪产业发展的新趋势,其核心主要聚焦于智能环控、智能饲喂和对猪群的视频监控等技术的应用。大数据采集是实现智能化的前提,因此,通过射频识别（RFID）技术建立猪只大数据是实现智慧养猪的基础。通过正确的猪只个体识别技术的选型,在不同生命周期给猪只选配合适的电子耳标,给猪只建立精准的身份证明。在不同阶段的数据采集场景中,通过识别电子耳标产生真实数据的关联,准确掌握每一头猪从出生到屠宰再到消费市场终端之间的信息,从而确保了动物健康养殖、疫病控制和食品安全,真正意义上实现智慧养猪。 相似文献

电子耳标一方面可满足农业部对个体动物的唯一标识和疫病追溯要求；另一方面可携带个体动物从出生到屠宰整个生命周期所有关键信息,满足农场信息化管理需求,实现精细化饲养的目的,对其进行空中接口参数测试可确保其与识读器正常通讯。通过实验室间比对,可对空中接口参数测试比对结果进行统计分析,发现实验室存在的问题,进一步提高检测水平。2021年,中国兽医药品监察所组织三家机构共同开展了电子耳标空中接口参数测试的实验室间比对工作,并依据Z比分数统计法对检测结果进行了分析,分析结果显示：59组数据为满意；1组数据为有问题；0组数据为不满意,总体上看测试结果一致性较好。 相似文献

A cost model was developed to compare different implementation strategies of the new European Commission regulation for sheep and goat identification and registration (EC 21/2004) in Spain. Strategies were as follows: 1) conventional identification (CID) by two ear tags; 2) electronic identification (EID) by one bolus and one ear tag; and 3) mixed CID and EID strategy (MID), consisting of CID for fattening stock and EID for breeding stock. Complete and simplified implementations of the regulation were considered as options. Total costs per animal identified for all strategies and options varied according to the implementation option, ranging from Euros 2.48 and 4.64. The EID was the most expensive strategy (Euros 4.47 to 4.64) for all implementation options. Cost of CID and MID strategies ranged from Euros 2.63 to 2.98 and from Euros 2.48 to 3.03, respectively. The model was submitted to a sensitivity analysis without considering extra benefits of sheep and goat identification. Critical values for which the cost of MID equaled CID depended on strategy and option, and ranged from 7.5 to 11.5% for ear tag losses and from Euros 1.80 to 3.30 for bolus price. In conclusion, the use of a mixed strategy combining conventional ear tags (animals intended for slaughter) and electronic boluses (breeding stock) seems to be an affordable strategy that fulfills the European Commission regulation requirements for the identification of sheep and goats in Spain. Price reductions for devices and equipment would make the full electronic identification strategy less expensive in the future. 相似文献
