Several years ago, following protests from animal welfare organizations, the European Union commissioned a report from its Scientific Veterinary Committee on these methods. The committee found that animals suffer from being unable to move freely and from the total lack of anything to do all day.
几年前，由于动物福利组织的抗议，欧盟委托兽医科学委员会对上述饲养方法进行了调查。委员会的结论是，动物因无法自由走动和整天无所事事而深受痛苦。勿庸置疑，任何有常识的人都会得出同样的结论。
