range这里指笼或圈, free range意思是没有笼子或没有圈养,换句话来讲就是放养,走地鸡鸭牛羊。 ...
维基百科上查的,差不多是这个意思,不过range意思更广一点,我之前说的有点偏。“Free range denotes a method of farming husbandry where the animals, for at least part of the day, can roam freely outdoors, rather than being confined in an enclosure for 24-hours each day.[1] On many farms, the outdoors ranging area is fenced, thereby technically making this an enclosure, however, free range systems usually offer the opportunity for extensive locomotion and sunlight prevented by indoor housing systems. Free range may apply to meat, eggs or dairy farming.” |
