目前,我县正大量发展养殖业,其中肉鸡饲养量比较大,而滥用抗生素的现象也表现的极为突出,所以,临床上出现了耐药菌株,急需做药敏试验,筛选敏感药物,否则滥用抗生素,一是产生耐药菌株;二是干扰正常菌群作用,对机体产生副作用;三是经济效益低。 相似文献

<正>滥用抗生素的范围不仅仅包括人,还包括畜牧养殖业。不少人提出,人们吃下"有抗食品"后间接摄入抗生素,因此要完全杜绝养殖业中使用抗生素。 相似文献

饲用抗生素对畜禽养殖业做出了突出贡献，但抗生素的使用过度带来了细菌耐药性、畜产品过量残留、间接威胁人类健康等不良后果。自2020年农业农村部194号公告正式实施，饲用促生长抗生素添加剂被全面禁止，无抗养殖成为畜禽养殖业发展的大趋势，抗生素替代物研究及应用成为行业热点。抗生素替代物主要通过竞争性抑制、阻碍黏附、特异性消除致病菌及提高宿主免疫力等方面发挥作用。本文综述了7种抗生素替代物的作用机制及研究进展，结合其在畜禽生产中的应用，为开发绿色、安全、无污染、无残留的抗生素替代物提供理论参考，以期推动我国饲料添加剂和健康养殖发展。 相似文献

抗生素在畜牧业中的广泛应用有效减少了动物疾病的发生和传播,促进了畜牧业的高效生产。但是,在目前畜禽养殖业中,由抗生素滥用导致的细菌耐药性问题严重影响了我国食品安全以及畜牧业的可持续发展。如何在目前减抗替抗的背景下,寻找具有预防疾病、促进生产性能的抗生素替代品,成为现阶段动物营养领域研究的热点。本文讨论了抗生素滥用给公共健康以及畜牧行业发展带来的危害,国内外减抗、禁抗的进程以及取得的成果,并介绍了抗生素替代品研究的相关进展,旨在为畜禽养殖业中抗生素替代品的选择与使用提供参考,推动畜牧业的健康绿色发展。 相似文献

<正>抗生素为养殖业、饲料业的发展起到了积极的促进作用,但由于其本身具有无法克服的弊端,因此,禁止使用抗生素是今后饲料业发展的大趋势。本文简要概述了抗生素替代品——微生态制剂的概念、作用机理以及在肉鸡业中与抗生素的对比研究应用。1饲用抗生素的应用现状自从1950年美国正式批准青霉素等抗生素在饲料中应用以来,抗生素作为一种非营养性的饲料添加剂在养殖业中得到了迅速而广泛的应用,其功 相似文献

随着抗生素应用的发展,其在畜禽养殖业的应用严重影响动物生产、生态环境及人类健康。基于食品安全、人类健康、环境保护等畜牧业面临的问题,抗生素替代产品的研发及应用是畜牧业发展的趋势,也是动物养殖业亟需解决的重要问题之一。本文结合国内外畜禽养殖业发展动态,综述了抗生素替代物在畜禽养殖业的研究与应用的相关进展,旨在为开发绿色、安全、无公害的抗生素替代饲料添加剂提供理论参考,推动我国畜禽无抗养殖的健康发展。 相似文献

从2006年1月起，欧盟将禁用抗生素生长促进剂（AGP）。人类抗生素耐药性的出现使得消费者产业恐惧，并迫使畜禽养殖业改变养殖生产方式。这不仅影响欧盟家禽养殖业而且也对全球其它地区的家禽养殖业产生影响。这个抗生素禁令究竟意味着什么呢？ 相似文献

In late December 1985, 1485 institutional veterinarians and small and mixed animal clinics across Canada were sent a questionnaire in order to assess the status of Dirofilaria immitis in Canada in 1985 and 44% of them responded. Veterinarians reported that 137,300 dogs were blood-tested to check for microfilariae and 1210 dogs were found with heartworm. Another 36 dogs were amicrofilaremic but diagnosed with heartworm disease to give the total number diagnosed in 1985 as 1247 (0.91%). Heartworm was reported from all provinces except Prince Edward Island, Newfoundland and Saskatchewan but most (1126) of the cases were in Ontario. Southwestern Ontario continued to be the primary focus of the infection in Canada. From Quebec, 91 cases were reported mostly from and around Montreal. From Manitoba, 19 cases were reported from Winnipeg and surrounding areas. Heartworm was found most frequently in companion dogs over three years of age maintained mainly outdoors in rural areas. About 28% of the cases were observed with clinical signs of heartworm disease and 78% had a history of not having left Canada. 相似文献

In late November 1988, 1581 small and mixed animal clinics and institutional veterinarians across Canada were sent a questionnaire in order to assess the status of Dirofilaria immitis in Canada in 1988, and 46% of them responded. Veterinarians reported that 181,577 dogs were blood-tested for heartworm disease and 367 dogs were found with D. immitis microfilariae. Another 60 dogs were amicrofilaremic but diagnosed with heartworm disease to give the total number of cases diagnosed in 1988 as 441 (0.24%). 相似文献

In late December 1984, 1853 institutional veterinarians and small and mixed animal clinics across Canada were sent a questionnaire in order to assess the status of Dirofilaria immitis in Canada in 1984 and 35% of them responded. Veterinarians reported that 97,794 dogs were blood-tested to check for microfilariae and 1417 dogs (1.45% of those tested) were found with heartworm. Another 34 dogs were amicrofilaremic, but were diagnosed as having heartworm disease, to give the total number diagnosed in 1984 as 1451 (1.48%). Heartworm was reported from all provinces except Prince Edward Island and Newfoundland but most (1310) of the cases were in Ontario. In Quebec, 126 cases were reported mostly from west of Montreal. Heartworm was found most frequently in companion dogs over three years of age maintained mainly outdoors in rural areas. About 27% of the cases were observed with clinical signs of heartworm disease and 72% had a history of not having left Canada. Southwestern Ontario continued to be the primary focus of the infection. 相似文献

In late November 1991, 1883 clinics in Canada were sent a questionnaire to assess the status of Dirofilaria immitis in dogs in 1991 and there was a 60.0% response. There were 344,031 dogs tested for heart-worm (HW), 627 were found infected and the prevalence of HW infection was 0.18%. There were 417 dogs with HW in Ontario, 116 in Manitoba, 38 in Quebec, 53 in British Columbia, three in Alberta, and one in Nova Scotia. In British Columbia, all of the infected dogs but one were from the Okanagan valley which, as from 1991, is a new focus of infection in Canada. Most dogs with HW had not been on preventive medication in 1990, and the prevalence among dogs tested and unprotected was 0.59%. That prevalence was considerably higher in endemic areas. Companion dogs, over three years of age and maintained primarily outdoors in rural areas, were most frequently infected. One cat was diagnosed with D. immitis and 33 dogs had Dipetalonema reconditium. 相似文献

In late November 1989, 1732 clinics and institutional veterinarians were sent a questionnaire to assess the status of Dirofilaria immitis, and 51.7% responded. Of 247,716 dogs tested, 394 had D. immitis microfilariae and 51 were amicrofilaremic for a total of 445 cases and heartworm prevalence of 0.17%. Most (408) of these dogs had no preventive medication and the prevalence among dogs tested and unprotected was 1.01%. That prevalence was considerably higher in endemic areas. Thirty-seven dogs with heartworm had preventive medication. Heartworm was most frequent in companion dogs over three years of age maintained outdoors in rural areas. About 75% of the cases had never left Canada, 26% had clinical signs and 125 were not treated. Heartworm was reported from British Columbia, Manitoba, Ontario, Quebec, Nova Scotia and Newfoundland, but 383 cases were in Ontario. South-western Ontario was the primary focus of infection. There were 33 cases in Quebec and 24 in Manitoba, mainly found in and around Metropolitan Montreal and Winnipeg respectively. 相似文献

In late December 1983, 2 800 veterinarians across Canada were sent a questionnaire in order to assess the status of heartworm disease in Canada in 1983 and 26% of them responded. Veterinarians reported that 59 504 dogs were blood-tested to check for microfilariae and 771 dogs (1.30% of those tested) were found with Dirofilaria immitis. Heartworm disease was diagnosed in all provinces except New Brunswick and Newfoundland but most (733) of the cases were in Ontario. Heartworm disease was found most frequently in companion dogs over three years of age maintained mainly outdoors in rural areas. About 31% of the cases were observed with clinical signs of heartworm disease and 64% had a history of not having left Canada. Southwestern Ontario continues to be the focus of the infection and most of the dogs there had not left the province previously. 相似文献
