猪之所以被认为笨,是因为它的体态肥。可是别看它其貌不扬,它的一些聪明才智连狗都比不上!科学家曾对猪进行过一连串的测试,跳舞、拉水、开门等,猪只要看一次人的示范动作就差不都可以学会了,而狗要近十次才能学会。现在,猪已经登上马戏台,表演起来比狗更精彩。
猪的视力和听力都不太强,然而,它的嗅觉比狮子狗还灵。于是有人训练猪打猎,它能嗅出二十多米外的猎物。住经过训练还能帮助寻找地下的`食物。
科学家还发现,猪也不是天生肮脏。猪皮肤上的汗腺不多,所以大热天为了散热,喜欢泡在水里;只是因为找不到干净的水,只好泡在泥水中,猪也懂得讲卫生,它总是尽可能地离开吃水的地方拉屎撒尿。只是人们将它关在猪圈里,没办法,它才弄得很脏。猪吃食有很强的选择性,凡是不爱吃的东西,决不肯勉强吃下去。它也懂得少吃多餐,细嚼慢咽。猪还能吃蛇,对蛇毒有很高的抵抗力。因此,美国有人在农田中放养猪,田里的毒蛇便明显减少了。
考古学家发现,早在近万年前,人类就开始驯化并饲养猪了。野猪身上披着硬毛,长得青面獠牙,性格十分凶猛。它跑得快,发起怒来真是无所顾忌,连兽中之王老虎也要怕它三分。而被驯化的家猪,一改野猪的恶性,在长相、性格上都发生了改变,还逐渐形成了发育快、繁殖力强的特点,因此成为经济价值最高的家畜。一猪多用,造福人类。猪不仅能供食用,还是制革制药的原料,就连粪便也是上好的农肥,得到了“浑身是宝”的赞誉。

猪的长相还不错。直面我们的是它粉红色的硕大的鼻子。全身雪白。当然不排除还有其他肤色。例如豪猪,野猪之类。猪的日子过得很平和。没有什么太多的祈求。猪活动的范围,就是它的居所,就是几丈宽的猪圈。几年如一日。常年的胡乱如厕。里面都很肮脏。若不打扫,常年的积累。恐怕会臭气熏天,无法忍受了。幸而猪的.适应能力强。什么环境都能适应。他们似乎很合群,每次在吃饭的时候,挤在猪槽里,哼哼着吃饭,大快朵颐。消化完食物后,偶尔摊在一起,打呼噜。
介绍完居住环境和它的长相之后,便是介绍它的聪明程度了。你会惊讶的反问:猪怎么也会聪明呢!太令人吃惊了!不是么?!不可思议。我不相信。”可是民间虽是喜欢用猪来臭骂和形容脑子呆笨的人,反应力迟缓的人,不肯动脑筋的人,懒惰的人,还有行动迟缓,思考力弱的人,虽说猪受到了冤屈,但是它从来都不抗议。或许他抗议了,但是语言不合。人类听不懂。猪其实是很聪明的动物。我这样一说,很多人会质疑。批评和不敢苟同。可是我有证据,读过书,在这里有一个事例。足以证明猪的聪明。在美国的一户人家,主人养育了一条狗和一只猪。主人为了省事,怕麻烦。就训练他们上厕所。训练了很久,于是让他们自己去上厕所。猪不仅灵巧地找到了厕所,还学会了用卫生纸。可是狗训练了一周之后,十分奇怪的是,它却连厕所的门都挨不着。他灵巧的鼻子做什么去了?它的主人很奇怪。猪的智商如此之高,当然这里要说明一下,是在动物界。从此之后,谁又敢轻易质疑猪的智商呢!虽然它肥笨的身材,使人误以为他是愚蠢的,其实不然。前文已经说过。
猪现在时来运转,莫名地被人当成了宠物。既然狗能成为家养的宠物。那么猪也是可以的。当之无愧的。
它性格温和,不吵不闹。老实巴交,实在也是作为宠物的极佳选择。选它做宠物,相信猪也是会同意的,虽然我们听不懂猪说的话。
