家畜寄生虫病的病原种类甚多,分布也很广,感染家畜后严重影响其生长发育,削弱其生产性能。目前临床抗寄生虫药物的大量不合理使用,造成耐药性不断增强、生物利用度降低;且某些药物存在毒副作用大、药效持续时间短以及残留量大等缺点;这给寄生虫病的防治工作带来了一定的困难。随着药物制剂工业的不断发展,特别是某些新型高分子辅料的出现,抗寄生虫药物制剂的种类也在不断地增加,这些新剂型的出现使得目前的抗寄生虫药物向着更加高效、广谱、长效的方向不断发展。该文谨对目前的抗家畜寄生虫病药物制剂的研究进展与展望做一综述。 相似文献

Aquaculture, for better or worse, depends in part on drugs for the prevention, control and eradication of a variety of diseases. The US Food and Drug Administration's Centre for Veterinary Medicine, through the Federal Food, Drug and Cosmetic Act, strictly controls the approval and use of drugs in animals, including aquatic animals. Laws and regulations exist that regulate the investigational use and approval of new animal drugs for all animals. However, in reality, these mandates must be uniquely interpreted for aquatic species. Very few drugs are approved for use in aquatic species. There is a growing effort by non-traditional sponsors (aquaculturists as opposed to pharmaceutical firms) to gain approvals for several new animal drugs. Simultaneously, the federal government, including the Centre for Veterinary Medicine, is working aggressively with the private and public aquaculture sectors to facilitate submission and subsequent approval of new animal drug applications. The drug approval procedures and requirements for aquatic animals are discussed. Special attention is given to their similarities and differences, relative to traditional terrestrial animals. 相似文献

Though fallow deer is considered very resistant to infectious diseases and parasites, diseases of different kind occur in enclosed pastures. Normally the diseases are the same as with wild animals or with farm ruminants. Diseases limited only to fallow deer are not known up to now. Parasitic diseases are a common problem, and prophylactic measures are necessary in all enclosed pastures to control parasites. Most losses in the enclosed pastures at the state farms of Grub and Romenthal caused by infections were due to necrobacillosis or to Coli bacteria. Because therapy is difficult or even impossible with wild animals, prophylactic measures are very important in enclosed pastures. Prophylaxis against Coli infections by improving the environment is possible only to a limited degree. Metabolic diseases and poisonings are mostly caused by wrong feeding. 相似文献

The majority of diseases in house pets results from inadequate husbandry. 2 of the law for animal protection defines the general claim of animals considering care and housing, but interpretation of the needs for each individual species requires specific veterinary knowledge. Overview tables and illustrations demonstrate diseases and causal husbandry mistakes in caged birds and house rodents. 相似文献
