3、states,whereas the latest definitions have reflected the complex, multi-faceted nature of animal welfare.人类对动物的理解尤其是它们的感知、需要和本性一直在发展。身体状况不佳的福利更容易获得,也更容易理解(特别是对兽医来说,他们承担了很多早期的福利工作)。但新的研究自然会让人们对心理状态、需求和本质有更深入的了解。动物行为学研究尤其如此,包括“偏好测试” ,即测量和评估动物的偏好。这也许就是为什么早期的福利定义以物质状态为中心,而最新的定义反映了动物福利的复杂性和多面性。Welfare v
4、RightsIn brief,The difference between animal welfare and animal rights can be explained as below:Animal welfare denotes the desire to prevent unnecessary animal suffering(that is,whilst not categorically opposed to the use of animals,wanting to ensure a good quality of life and humane death).动物福利指的是
5、希望避免不必要的动物痛苦(即,虽然没有明确反对使用动物,但希望确保良好的生活质量和人道的死亡)。Animal rights denotes the philosophical belief that animals should have rights,including the right to live their lives free of human intervention(and ultimate death at the hands of humans).Animal rightists are philosophically opposed to the use of anim
6、als by humans (although some accept symbiotic relationships,such as companion animal ownership).动物权利指的是一种哲学信仰,即动物应该拥有权利,包括不受人类干涉(以及最终死于人类之手)地生活的权利。动物右翼分子在哲学上反对人类使用动物(尽管有些人接受“共生”关系,比如伴侣动物所有权)。Welfare v Conservation 福利 v 保护The key difference between conservation and animal welfare is that conservation
7、 cares about species(and extinction)whereas animal welfare cares about the individual animal (and its suffering).Animal welfarists belief that each individual animal has an intrinsic value,and should be respected and protected.They recognise that animals have biologically determined instincts,intere
8、sts and natures,and can experience pain and suffer,and believe that they should therefore be permitted to live their lives free from avoidable suffering at the hands of humans. It is not difficult to see why the conservation movement has attracted support more readily than the animal welfare movemen
9、t.Animal welfare requires greater altruism and empathy than conservation. Care for conservation can be generated by human-centred objectives, such as not wanting species to become extinct because of the loss for future generations(of humans). Although many people now recognise that animals feel pain
10、 and suffer,this comes lower down on their list of priorities for actionand may indeed challenge their own lifestyle and habits.保护和动物福利的关键区别在于,保护关心的是物种(和灭绝),而动物福利关心的是单个动物(和它的痛苦)。动物福利主义者相信每一只动物都有其内在价值,应该得到尊重和保护。他们认识到,动物具有由生物学决定的本能、兴趣和天性,能够经历痛苦和痛苦,因此,他们认为,动物应该被允许在生活中免受人类可以避免的痛苦。不难看出为什么自然保护运动比动物福利运动更容易
11、得到支持。动物福利需要比保护动物更大的利他主义和同情心。保护可以通过以人为中心的目标来产生,例如不希望物种因为(人类)后代的损失而灭绝。尽管许多人现在认识到动物会感到痛苦和痛苦,但这在他们的优先行动清单上排名靠后,可能确实会挑战他们自己的生活方式和习惯。Welfare DefinedWelfare is not just absence of cruelty orunnecessary suffering.It is much more complex.It includes the following different states:福利不仅仅是没有残酷或“不必要的痛苦” 。它要复杂得多。
12、它包括以下不同的状态:Physical State: traditionally definitions centred on the physical state ofanimals. However, it is a simplistic view that welfare is only poor when survival or reproduction is impaired by a physical problem.传统上,动物的生理状态是定义的中心。然而,有一种过于简单的观点认为,只有当生存或生殖受到生理问题的损害时,福利才会低下。Mental State: Mental st

14、hese harms its welfare.This third dimension has been recently recognised and added.自然: 第三种状态自然是指动物满足其自然需要和欲望的能力。这些挫折损害了它的福利。这第三个维度最近得到了承认和补充。The definition ofanimal welfare is often debated.However,these three states,which are given in the definition given by WSPA in itsConcepts of Animal Welfarevet

20、识到,在动物由人照顾的情况下,某些自由可能会发生冲突。治疗(如兽医治疗)治疗疾病与免于恐惧和痛苦(可能由处理和程序引起) 之间的冲突。NeedsThe termneedsis often used in discussions on welfare,as needs are the things that should be provided to ensure an animals welfare.“需要”一词常用于有关福利的讨论中,因为需要是为确保动物福利而应提供的东西。A need is:A requirement,fundamental in the biology ofthe ani

23、。在需求退出后观察效果,可以看出它们的相对重要性。Sentience 感知There is now widespread recognition of thesentienceof animals,which reinforces the need to protect welfare.The European Union has officially recognised animals to be Sentient Beings(1997).Sentience implies that animals:现在人们普遍认识到动物的“感知能力” ,这就加强了保护动物福利的必要性。1997 年,欧
