有机饲料在我国畜牧业中的发展前景

随着我国畜牧业的迅猛发展，在推动社会经济发展的同时，对生态环境、畜产品也造成了很大污染，畜禽粪便污染已成为农村污染的主要根源。同样，农药、抗生素、激素、霉菌毒素、重金属等有毒有害物质在畜产品中的残留，对人类的健康也已构成威胁。因此，在不影响畜产品产量和质量的前提下，如何降低畜牧业污染，提高畜产品的安全性已成为人们关注的焦点，同时也是研究的热点。     

应用环保饲料促进健康养殖

我围畜牧业的迅猛发展，在推动经济发展的同时，给生态环境、畜产品安全问题也带来了很大的难题。当前，畜禽粪便污染已成为农村污染的主要根源。同样，农药、抗生素、激素、霉菌毒素、重金属等有毒有害物质在畜产品中的残留，对人类的健康也已构成威胁。因此，在不影响畜产品产量和质量的前提下，如何降低畜牧业污染．提高畜产品的安全性已成为人们关注的焦点。     

畜产品安全要从健康养殖抓起

随着国民经济的发展和人民生活水平的提高,人们对营养与健康越来越重视,肉、蛋、奶等畜禽产品在人们食品中的比重也越来越大,畜产品安全已日益成为焦点问题,而且直接关系到人们的身体健康.针对近年来我国相继发生的一些重大食品安全事件,本文对畜产品主要污染情况进行分析,提出解决畜产品安全的措施和建议,确保畜产品质量安全.     

饲料生产与环境保护

随着我国畜牧业和饲料工业的持续快速发展和人民生活水平的不断提高，人们对畜产品的质量也提出了更高的要求。畜产品内有毒、有害物质的残留和污染，在很大程度上降低了畜产品质量，危害了人民身心健康，同时对环境也造成了很大污染。畜牧业对环境的污染主要来自粪、尿、气味及畜产品的有毒有害物残留，造成环境污染的主要根源在饲料。因此，饲料工业需要从立法、管理、生产、销售、使用等各环节进行规范，对从业人员加强行业教育，提高行业整体水平。生产过程的污染１－粉尘污染粉尘污染是饲料厂的主要污染源之一。对环境和生产饲料的工人…     

影响畜产品安全的因素及其解决措施

随着我国畜牧业和兽药生产的迅速发展,人们生活质量意识的不断提高,对无污染的绿色食品也越来越偏爱。由于饲料污染、药物残留等问题,严重影响了畜产品的品质,阻碍了畜牧业可持续发展,同时,面对欧盟、日本等国家对畜产品质量的严格要求,势必对我国畜牧业形成严峻的挑战。因此,科学合理的解决畜产品安全问题已成为迫切需要解决的课题。     

提高畜产品质量的主要措施

随着饲料工业和畜禽养殖业的发展,畜产品的数量已不再是人们生活需要的首要问题,而畜产品的质量优劣已成为人们关注的重点。英国出现的“疯牛病”事件给英国百年称雄的肉牛业带来了致命的打击。比利时发生的“二噁英”污染事件导致其畜牧业及畜产品加工业瘫痪以及我国因畜产品质量问题使畜产品出口受阻,这都说明畜产品的品质不仅关到畜牧业的健康发展,也关系人们的健康和生存,因此,生产安全,放心、高质的畜产品是畜牧业的发展方向。     

加强畜产品质量安全的长效机制

畜产品的质量安全问题已成为畜牧业发展的主要问题之一,畜产品因兽药残留和其他有毒有害物质超标,以及产地环境、生产过程、加工过程造成的污染引发的中毒事件时有发生,给人们正常消费畜产品和维护公共安全造成了极不协调的音符,同时也给国家发展畜牧业造成了严重的经济损失。提高畜产品质量不仅是提高畜产品竞争力的关键措施,同时也是构建环境友好性、可持续发展的和谐社会的必由之路,是维护公共安全的有效措施。     

认真落实科学发展观 切实抓好畜产品质量安全

<正>食品是人类生存的最基本需求,食品安全也是社会稳定和发展的永恒话题,随着我国经济发展和城乡居民收入不断增加,在畜产品产量大幅度增长的同时,兽药、饲料及饲料添加剂等投入品也越来越多,因此畜产品的品质和安全、养殖业对环境的污染、动物疫病的防控越来越引起社会关注。全面提高畜产品质量安全,不断转变畜牧业发展方式,已成为新时期畜牧业加快发展的一项重要任务。     

影响畜产品安全的因素及其解决措施

随着我国畜牧业和兽药生产的迅速发展,人们生活质量意识的不断提高,对无污染的绿色食品也越来越偏爱。由于饲料污染、药物残留等问题,严重影响了畜产品的品质,阻碍了畜牧业可持续发展,同时,面对欧盟、日本等国家对畜产品质量的严格要求,势必对我国畜牧业形成严峻的挑战。因此,科学合理的解决畜产品安全问题已成为迫切需要解决的课题。     

基于优化农村养殖环境的畜产品质量安全生产对策

随着农业产业结构的调整,畜牧业在我国国民经济中的地位日益重要,已成为当前农村经济的支柱产业。然而,畜牧业的发展也带来了一些严重的社会问题,主要表现在养殖污染日趋严重和畜产品质量安全堪忧。介绍了当前畜产品生产质量现状,提出了优化农村养殖环境的对策,以确保畜产品质量安全,促进畜牧业健康、可持续发展。     

Heartworm in dogs in Canada in 1984

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.
