  What a pig sees when it looks into a mirror may help Agricultural Research Service (ARS) scientists improve livestock housing.

  猪在照镜子时会看到什么呢?这个问题的答案可以帮助农业研究服务(ARS)科学家对改善家畜住房进行研究。

猪爱照镜子

  Studying livestock behavior, stress and other well-being and production factors is the job of animal scientist Jeremy Marchant-Forde and his colleagues at the ARS Livestock Behavior Research Unit in West Lafayette, Indiana. Improving an animal's environment can reduce stress, which in turn, enhances well-being, growth and efficiency, and decreases disease susceptibility.

  研究牲畜的行为,压力、其他福祉和生产要素是动物科学家杰里米·马桑特·福特(Jeremy Marchant-Forde)及其同事在印第安纳州西拉法叶的“农业研究服务家畜行为研究中心”要做的工作。

  In a study, Dr Marchant-Forde looked at different types of pig pens. Pigs had access to a standard pen with a metal floor (the "control" pen), one with a rubber mat on the floor, another with a mirror and a fourth with a view of another pig across a passageway. Pigs preferred spending 40 per cent of their time in pens where they could see another pig. They spent 10, 20 and 30 per cent, respectively, in the control, mirror and mat pens.

  在一项研究中,Marchant-Forde博士研究了不同类型的猪圈。猪被分别带进四个棚:第一个是带有金属地板(“控制”棚)的标准棚,第二个是在地板上有橡胶垫的猪棚,第三个猪棚带有镜子,第四个猪棚则可以通过通道看到其他猪。猪喜欢把40%的时间花在能看到另一头猪的棚里。它们分别在控制棚、镜子棚和橡胶垫棚里停留了了10%,20%和30%的时间。

  In a second experiment, scientists examined which pens pigs preferred when a person was present. When a person was in sight, pigs spent nearly 90 per cent of their time in either the pen with the mirror or where they could see another pig. Dr Marchant-Forde hypothesized that pigs saw their reflection in the mirror as a companion, but more research is needed for confirmation.

  在第二个实验中,科学家研究了当有人类在场时,猪会首选哪个猪棚。实验发现,当人出现在猪的视野中时,猪花了近90%的时间在有镜子的猪棚,或者他们可以看到另一头猪的那个猪棚。Marchant-Forde博士的摄像是,猪把镜子里的自己当成了同伴,但需要更多的研究来确认。

  Having mirrors in a commercial production, where pigs are kept in groups, would not be feasible, Dr Marchant-Forde notes. However, producers could consider using rubber mats to help improve the pigs' environment, which may help reduce stress and promote health and productivity.

  Marchant-Forde博士指出,在商业生产中给猪群里放一个镜子是不可行的。然而,生产者可以考虑使用橡胶垫来改善猪的环境,这可能有助于减轻压力,促进健康和生产力。(责任编辑:君君)
