生态环境(包括人们的生产生活)对动物生命活动及其致病因素的影响十分巨大而深远;动物的生命活动及其致病因素对生态环境影响直接而明显;两者相互关联、相互影响、相互作用、互为一个整体.因此,动物医学应将生态环境从宏观上作为重要的研究对象,并在实践中采取综合措施既有效地控制疫病,又能保护生态环境.研究和应用生态环境与动物医学之间的关系,具有很重要的作用和意义. 相似文献

<正>兽药在降低动物发病率与死亡,促进动物生长和改善动物产品品质等方面起着显著作用,已成为现代畜牧业不可或缺的因素。然而大量的不合理应用兽药,不但最直接的对动物产生毒害、耐药性、降低生产性能等影响外,而且还间接对土壤、水体等生态环境产生不良影响,并通过食物链对生态环境产生毒害作用,影响环境中动植物和自然微生物的生命活动,最终影响人类健康,后果不容忽视。1动物的种类、体重、年龄、性别动物种类的不同,决定其的生理机能、解剖结构不同,从而 相似文献

通过查阅资料和调查总结了蒙古族的游牧生活与文体文化。蒙古族牧民乌琦大皮极为适应高原日温差大的自然环境,耐贮藏富营养的肉、奶、面食品和蒙古包最适合游牧生活方式。总之,蒙古族牧民的衣、食、住、行都与环境相适应。蒙古族牧民能歌善舞,创造了称为"草原文化三宝"的长调、马头琴、呼麦。其中,蒙古族长调民歌被联合国教科文组织列为"人类口头和非物质遗产代表作"。中国第1个文化遗产日颁布的第一批非物质文化遗产名录中,就有蒙古族长调民歌、呼麦、格斯尔、乌力格尔、安代舞、达斡尔族鲁日格勒舞、蒙古族马头琴音乐、成吉思汗祭典、鄂尔多斯婚礼、祭敖包、那达慕等17项。蒙古族的竞技体育活动包括骑马、摔跤、射箭、赛跑、游泳、抛套索"等,这些活动也与狩猎、游牧活动密切相关。蒙古族牧民创造的鹿棋、蒙古象棋、嘎拉哈、古尔等游戏丰富了中华牧业文化遗产宝库。 相似文献

从时代发展、保护教育与游客需要、动物的生理与心理需求和动物园自身发展的角度说明了动物园进行环境丰容的必要性。对野外生活环境下与圈养条件下动物生存条件的差异进行了比较,丰容工作应依据野生动物的自然史,充分利用动物学、动物生态学、动物地理学、保护生物学和动物行为学等相关学科的基础知识及其研究成果,根据动物的生物学特性,增加自然因素,提供更多的刺激,给动物更多的选择,增强动物的主体能动性,使动物展示出更多的自然行为,并结合动物园实际指出了进行丰容工作的注意事项。 相似文献

随着全球生态环境日趋恶化,区域生态经济系统的恢复与重建已引起国际社会的广泛关注。通过分析党河中上游生态退化的内在原因和外在驱动力,认为党河中上游生态退化的前提是气候的干旱性和生态环境的脆弱性,最大干扰因素是人类经济活动。今后,党河中上游地区必须高度协调人地关系,减轻生态压力,同时要加强党河流域的水资源统一管理,优化水资源配置,依托退牧还草和国家自然保护区政策,力争用较少的时间使党河中上游生态环境得以修复。 相似文献

Canine and human atopic dermatitis are multifaceted diseases whose clinical development may be influenced by several factors, such as genetic background, environment, secondary infections, food and psychological effects. The role of the environment has been extensively examined in humans but remains unclear in dogs. The aim of this study was to examine environmental factors in two genetically close breeds, Labrador and golden retrievers. Using standard criteria, atopic dogs in Switzerland and Germany were selected and compared with healthy individuals. Information on environmental factors was collected using a 46-question survey encompassing date and place of birth, way of life at the breeder's and owner's home, food and treatments. Univariate and multivariate logistic regression were used to assess the association between potential risk factors and disease status. The following parameters were associated with an increased risk of disease development: living in a shed during puppyhood, adoption at the age of 8-12 weeks and washing the dog regularly. In contrast, the following factors were associated with a lower risk: living in a rural environment, living in a household with other animals and walking in a forest. These associations do not prove causality but support the primary hypothesis that certain environmental factors may influence the development of canine atopic dermatitis. Further studies are warranted to confirm these results and conclusions. 相似文献

The economically important diseases of agricultural animals are those that affect groups of animals to result in impaired productivity or mortality. Herd and flock disease result from complex interactions between inciting agents (or other etiologies), and factors such as management systems, nutrition, environment and other contributory causes. For these reasons herd and flock disease problems must be addressed, researched, and taught, in the areas where they occur-on the farm and in the field. For political and educational reasons this needs to be on farms throughout the state or region represented by a veterinary school. Like most studies, this type of study needs to have a multidisciplinary input but these inputs often involve disciplines that are different from those that address clinical disease in individual animals in the veterinary teaching hospital setting. Clinical departments in veterinary schools have not traditionally found funds to support this approach to agricultural animal disease. This talk will discuss the establishment of a conjoint program between the College of Veterinary Medicine and the College of Agriculture at Washington State University (Field Disease Investigation Unit) to address these requirements and its activities over the past 25 years. 相似文献
