饲料添加剂残留进入生态环境,对环境土壤、土壤生物、水体、水生生物及动植物均造成不良影响,可造成对环境的直接危害;其本身由于环境影响发生转移、转化或在植物、动物体内富集,在食物链中传递,输入人或动物体内,并通过食物链对环境产生间接危害.为了降低饲料添加剂的生态危害,应用新型饲料添加剂替代常用的饲料添加剂是一条积极可行的途径. 相似文献

饲料产品的安全性是评判饲料产品质量的重要指标。要保证饲料安全,就是要保证饲料产品（包括饲料和饲料添加剂）一般的卫生指标（铅、砷、氟、黄曲霉素B1等）在国标范围内,不含有对饲养动物健康造成实际危害,在动物体内的残留造成整个食物链的安全隐患,畜禽粪便排出后对生产环境及使用环境造成污染的有毒、有害物质或因素。 相似文献

兽药残留产生的途径、危害及控制措施 总被引：1，自引：0，他引：1
广义上的兽药残留除了由于防治疾病用药引起外，也可以由于使用药物饲料添加剂、动物接触或吃人环境中的污染物如重金属、霉菌毒素、农药等引起。兽药残留超标不仅可直接对人体产生急慢性毒性作用，引起细菌耐药性增加，还可以通过环境和食物链的作用间接对人体健康造成潜在危害，并影响养殖业的发展。因此，必须采取有效措施减少和控制药物的残留。 相似文献

Alternaria is a saprophytic fungus that is widespread in the environment; it is an opportunistic pathogen and causes disease in human beings and domestic animals. Fungal spores gain entry to the host through skin lesions and cause slow-growing, soft to firm, subcutaneous swellings, either with or without ulcers. An indirect ELISA was developed for the detection of anti-Alternaria immunoglobulin G (IgG) antibodies in serum to determine the prevalence of Alternaria exposure in domestic cats. Fifty-two of 63 cats had detectable levels of anti-Alternaria IgG antibody. There were no correlations between the concentration of antibody and the sex, breed or living environment of the cats, but cats less than two years of age had significantly lower concentrations than older cats. The cats with disease caused by culture-confirmed Alternaria infections did not have significantly higher concentrations of antibody than the healthy cats or cats with other diseases. 相似文献

Man's position in nature is equivocal. Man is part of nature and through evolution is linked to other living beings. Although an "Animal among Animals", nature has provided him with capabilities that separate him from all living beings in its realm. These comprise the ability for reflection and subsequent moral behavior, but also the gift (and necessity) for using technology to shape and subjugate his natural environment. Based upon this "Dual Nature of Man" the essay focuses on the web of interactions between Man, Nature and Technology. Modern ethics of animal protection argue in favor of extending the principle of equality ("To Each His Own") to include animals as well. However, the principle of equality is a purely formal, heuristic rule for assigning morally just determinations of value. It requires normative padding as far as its content is concerned. Consequently, the content of the principle of equality ought to be more closely determined in keeping with the ideal of humanity. 相似文献

试验采用完全随机区组试验设计,以2个刈割茬次的甘农3号(Gannong No.3)紫花苜蓿为原料,分别添加青贮添加剂露保美NC、宜生贮宝、亚芯、乳酸菌发酵剂YM3和YM7、河北沧州乳酸菌进行裹包青贮,以不加添加剂为对照,45d后进行青贮指标测定、数据分析和灰色关联度分析,以研究添加剂对不同刈割茬次紫花苜蓿裹包青贮发酵品质的影响。结果表明:6种添加剂均能改善紫花苜蓿裹包青贮品质,且添加剂处理组优于对照组,其中,亚芯处理组pH最低,乳酸含量多,无丁酸(BA)生成,氨态氮含量最少,可溶性碳水化合物(WSC)消耗最低,发酵品质最好。且第2茬刈割的青贮品质优于第1茬。 相似文献

The health of animals grazing on pastures is affected by the mineral content of fodder plants. The mineral content of any pasture species may vary within very wide limits and is profoundly influenced by fertilisation. Some of the known facts about animal health in relation to the supply of mineral nutrients in pasture dry matter are presented, together with a discussion of how the uptake of minerals by animals may be influenced by the fertilization of pastures. 相似文献

Will and knowledge of animals as topic of evolution-theoretical investigations
Only living beings have a will for action, and all living beings with the exception of man can will nothing else but to survive. The innate will drives them to self-preservation, species-preservation, and self-organization. Only man can renounce to do so. This uniform will is supported by the most differentiated knowledge. In cells this knowledge is chemical and by sensation; in animals it is physical and by sensation. It senses and remedies three bodily needs: hunger, disease, and propagation. Only know-how can remedy needs. The need for knowledge is therefore the primary need, and improvement of knowledge is the decisive evolutionary change.
Chemical knowledge by sensation in most cases is genetic, ground-conscious, and hereditary knowledge. In physical knowledge acquired by sensation, ground-consciousness is lifted to the instinct-conscious level of the nerve cells through which learning-consciousness is developed further. The laws governing this are described elsewhere. 相似文献

Konnie H Plumlee 《Veterinary Clinics of North America: Small Animal Practice》2002,32(2):383-395
A variety of plants, seeds, and nuts can cause toxicosis in small animals. Some plants are not as toxic as commonly believed by the general public. Conversely, plants or nuts that are consumed by human beings can be toxic to their pets. Most plant toxins do not have specific treatments or antidotes. As a result, treatment is often limited to decontamination plus symptomatic and supportive care. 相似文献

中国是世界上动植物种类最丰富的国家之一，但国内对野生两栖爬行动物的掠夺性利用还在发展；国内野生两栖爬行动物资源在这种疯狂的掠夺下已经接近枯竭，多数物种处于濒危状态。动物园作为野生动物异地保护的重要场所，饲养繁殖野生动物的最终目的是实现濒危物种的再引入，恢复野外种群数量．出于以上目的，动物园中两栖爬行动物的饲养管理方式有别于爬虫爱好者单纯的满足对宠物的要求和增殖牟利追求。这种区别不仅表现在选择动物种类方面，更多的体现在丰容概念的引入及工作方法的应用：营造合理的饲养环境、饲养环境小气候的周期性变化、设施的丰容、群体的调整、食物及供给方式的变化、对繁殖行为的鼓励等。这些丰容手段对保持两栖爬行动物的自然行为，从而保证动物的野外生存能力具有重要作用． 相似文献
