为了更全面地了解和掌握喹烯酮对鸡的促生长效应,设计试验了喹烯酮的剂量优化试验和药效比较试验。不同水平喹烯酮对肉鸡促生长的研究,采用单因子随机分组试验设计,喹烯酮的添加水平分别为0.0,25.0,50.0,75.0,90.0mg/kg,共5组;不同种类药物饲料添加剂对肉鸡的促生长作用研究,采用随机分组设计,各组基础日粮相同,采用它们的推荐剂量,药物分别为喹烯酮、喹乙醇和黄霉素。结果表明,饲料中添加75.0mg/kg喹烯酮在提高肉鸡平均日增重、采食量和饲料转化率方面效果最佳;与黄霉素、喹乙醇相比,喹烯酮提高日增重和改善饲喂效率效果最显著,且与黄霉素一样能显著地降低死亡率。 相似文献

Recombinant-DNA (transgenic) animals intended for food production are approaching the market. Among them, recombinant-DNA fishes constitute the most advanced case. As a result, intergovernmental organizations are working on guidelines which would eventually become international standards for national food safety assessments of these products. This article reviews the emerging elements for the food safety assessment of products derived from recombinant-DNA animals. These elements will become highly relevant both for researchers and regulators interested in developing or analyzing recombinant-DNA animals intended to be used in the commercial elaboration of food products. It also provides references to science-based tools that can be used to support food safety assessments. Finally, it proposes recommendations for the further development of biosafety assessment methodologies in this area. 相似文献

Farm animal welfare: the five freedoms and the free market 总被引：1，自引：0，他引：1

This review addresses the scientific, ethical and economic factors that impact on the welfare of farm animals. Respect for animals within the food chain is considered within the context of an ethical matrix that affords respect according to the principles of wellbeing, autonomy and justice to consumers, farm animals, farmers and the living environment. The welfare of a farm animal depends on its ability to sustain fitness and avoid suffering. The responsibility of the farmer is to make provision for good welfare through good husbandry; he cannot ensure good welfare. Improvements to farm animal welfare can only come about within the context of the forces that drive the free market. In essence, consumers need to afford a greater extrinsic value to farm animals. The costs to farmers of legislation to impose higher animal welfare standards are substantial but the cost to consumers can be very small. The responsibility is therefore on the consumer to convert an expressed desire for higher welfare standards into an effective demand. A promising route to encourage and fulfil this demand is through welfare-based quality assurance schemes with quality control ensured by independent audit. At present, audit protocols are based largely on identification of the elements of good husbandry. Ultimately we need a further independent audit to ensure that the outcome of these perceived elements of good husbandry is, in fact, good animal welfare. 相似文献

An increasing number of product claims about food animal welfare or well-being have appeared in the global food industry and global market in recent years. These claims have significant consequences for producers, processors, transporters, retailers, consumers, and the animals themselves. Furthermore, recent restructuring of the global food industry has altered the power relationships of various actors. Regulation of the industry is moving toward greater private control, and the power of retailers has dramatically increased. The changing structure of the industry carries implications both in terms of how standards are created and in terms of the types of standards themselves. The purpose of this article is to provide a greater understanding of how these product claims are made, their implications, and the challenges they present. 相似文献

肉与肉制品是人民日常生活膳食中十分重要的一个部分,肉类的进出口也是我国对外经济贸易的重要一环。肉制品安全的相关法规标准的建立和完善是各国十分重视的一项工作。影响肉制品安全的因素众多。化学因素方面有肉类中残留的农药兽药,动物通过食物链摄入和富集的有毒元素,生产过程中加入的食品添加剂,工业生产和燃烧产生的二噁英、多环芳烃等有毒化合物,都有可能对人体产生严重的影响;生物因素方面有动物本身带有的寄生虫、细菌和病毒,因生产和保存不当而导致肉类变质的细菌、霉菌等,也是严重影响人体健康的潜在因素。围绕这些因素,我国制定了许多法规标准,保障肉制品安全。 相似文献

Close interactions are existing between poultry husbandry and poultry health. The more housing systems and the environment of the animals can be controlled, the less the general risk of disorders in poultry flocks--especially of diseases which are caused by the introduction of microoganisms. Resulting deterimental effects will affect not only the animals themselves, but also pose a risk indirectly for humans via food originating from animals under production. Also, by keeping the risk of infections as low as possible, the use of therapeutics can be avoided. This will reduce the risk of residues in food of animal origin. In summary, with all probability open poultry husbandry systems, especially those including free range systems pose increased risks for poultry health and consequently for the quality of food originating from poultry production. At least, those systems require highest standards of biosecurity, defined as management, location, farm layout, cleaning and desinfection incl. pest control programs, immunization and specific veterinary monitoring concepts to prevent infections. 相似文献

Enterohaemorrhagic Escherichia coli: emerging issues on virulence and modes of transmission 总被引：5，自引：0，他引：5
Enterohaemorrhagic Escherichia coli (EHEC) constitute a subset of serotypes (E. coli O157 and some other serogroups) of Shiga toxin (Stx)-producing E. coli (STEC) firmly associated with severe human illnesses like bloody diarrhoea and haemolytic uraemic syndrome. Stx production is essential but not sufficient for EHEC virulence. Most strains are capable of colonising the intestinal mucosa of the host with the "attaching and effacing" mechanism, genetically governed by a large pathogenicity island (PAI) defined as the Locus of Enterocyte Effacement. Other virulence factors carried by mobile genetic elements like PAI and plasmids have been recently described, and their role in the pathogenic process has not been fully elucidated. EHEC are zoonotic pathogens. They rarely cause disease in animals, and ruminants are recognised as their main natural reservoir. Cattle are considered to be the most important source of human infections with EHEC O157, and the ecology of the organism in cattle farming has been extensively studied. The organism has also been reported in sheep, goats, water buffalos, and deer. Pigs and poultry are not considered to be a source of EHEC and the sporadic reports may derive from accidental exposure to ruminant dejections. The epidemiology of EHEC infections has remarkably changed during the past ten years and an increasing number of unusual food vehicles have been associated with human infections. New routes of transmission have emerged, like contact with animals during farm visits and a wide variety of environment-related exposures. As for other zoonotic agents, having animals and raw products that are free from EHEC is not possible in practice. However, their occurrence can be minimised by applying high standards of hygiene in all the steps of the food production chain. 相似文献

Presently, in the United States, there are no nonsteroidal anti-inflammatory drugs, except aspirin, that are approved for use in animals intended for food production. Use of phenylbutazone, flunixin meglumine, and dipyrone for treatment of food animals may be considered in special circumstances. Such use requires strict adherence to FDA guidelines for extra-label use of drugs. Flunixin meglumine and phenylbutazone have been shown to have a favorable influence on the course and outcome of certain diseases. This report reviews information concerning the pharmacology, pharmacokinetics, and therapeutics of phenylbutazone and flunixin as they have been used on an experimental basis in food animals. 相似文献

The availability of antidotes in veterinary medicine has been an issue for more than a decade. Antidotes are available for food animals through extralabel use, regulatory discretion, and compounding. There is little economic incentive for pharmaceutical companies to pursue approval of antidotes and other drug products that have a small market. In addition, human food safety concerns must be addressed when approving antidotes for use in food animals. This article provides a brief history of antidote availability, current mechanisms for procuring food animal antidotes, and availability of specific antidotes for use in food animals. 相似文献
