陈瑞阳版奶牛考~~~太搞笑了

前段时间,不知和谁聊起来说,有没有公的奶牛。

https://i2.wp.com/www.fsl.orst.edu/sdmg/images/world_cow.jpg?w=300

首先来看看败毒怎么说

最佳答案:

是这样的,这个问题我们也一直在讨论,后来遇到一个家在农场的朋友,他说出了奶牛的事情:

1,当然奶牛分公母。

2,专门的奶牛场基本没有公奶牛,而每年的交配季节会有人专门带来优质纯种公奶牛提供配种服务。

3,如果奶牛场的母奶牛产下公牛,小公牛的结局基本都是被宰杀掉(可能吃肉吧);如果母奶牛产下一公一母双胞胎,那么不论公母一律宰杀,因为据说这种情况下的小母牛长大后产的奶质量数量都不好。

总的来说公奶牛的命运是很可悲的。这样这个问题的答案已经出来了,但这还是不够的。

金山糍粑告诉我们:

cow

cow 1

AHD:[kou]

D.J.[kau]

K.K.[ka&]

n.(名词)

The mature female of cattle of the genus Bos. 

小母牛:指母牛属 的成年雌性牛

The mature female of other large animals, such as whales, elephants, or moose.

大型雌性动物:其他的大型动物(如鲸鱼、大象或麋鹿等)的母兽

A domesticated bovine of either sex or any age.

不分性别和年龄的家牛

如此说来,cow与奶牛的对应关系是片面的。

有些人用英文问了同样的问题结果得到这样的答案

This is like asking what is a male woman called!

A cow is a female and there is no male version of a cow. A bull is the male variety of cattle. A cow is the female variety of cattle. A steer is a neutered version of a bull (so it was born a bull, but has been desexed). To take it one step further, a Heifer is a young cow which has either borne one or no calf, depending on your reference book.

顺藤摸瓜,可以去google image上看一下,image:奶牛 vs image: cow。这个东西防火墙也不会管,自己看好了。 虽然大部分的cow 的图片都是和我们想像的一样的,还是有一些是例外的。

最后的解决还要看维基。

查询cow这个词,直接被重定向到cattle去了。看来,维基也觉得cow只是母牛而不是奶牛

中文奶牛的对应词语是dairy cattle

这一段可以看出,全天下的公奶牛都是痛苦而悲哀的, 弱势到连生存的意义都没有,甚至连它的存在都要受人质疑。

In New Zealand and some other countries male calves are slaughtered at two to four days for their abomasum (fourth stomach), rennet and for veal.

In Europe and North America most newborn dairy bulls will be slaughtered for veal before reaching six weeks of age. Many bulls, however, will be raised as steers and butchered for dairy-beef when about eighteen months old.

A select few high-quality bulls, however, will be raised for breeding purposes. These bulls will generally have excellent conformation, or type (for the breed), outstanding pedigrees and, early in their breeding life, produce progeny that is superior in dairy production.

Herd bulls, or bulls that live with dairy cows and provide direct, natural breeding, will service up to one hundred fifty cows at any given time. Such a bull will be used in one herd for up to two years before the risk of inbreeding and the bull’s increasingly hostile temperament forces a farmer to move the bull to a new herd.

问题到这里,还有一小部分未解决,我们平时印象中的奶牛形象是哪里来的

来自于维基的holstein条目的奶牛历史

300 BC: Pastoral nomads from Central Asia arrived with their cattle in the river Ems / middle arm of the Rhine area.

100 BC: A displaced group of people from Hesse, migrated with their cattle to the shores of the North Sea near the Friesians, occupying the island of Batavia, between the Rhine, Maas and Waal. Historical records suggest these cattle were black; and that the Friesian cattle at this time were “pure white and light coloured”. Crossbreeding may have led to the foundation of the present Holstein-Friesian breed, as the cattle of these two tribes from then on appear identical in historical records.

同时,有一条隐性基因可以决定奶牛的毛是红白相间,这条基因的影响最早在13世纪的中欧被发现,但是一直到二十世纪六七十年代这种颜色的奶牛才被牛奶行业普遍接受。google上找到的图片也有一些是这种颜色的
