动物王国的顶级乳汁

The Most Extreme Milk In The Animal Kingdom

Imagine feeding your baby a milkshake for every meal.
想象一下 每顿饭都给你的宝宝喂一杯奶昔
Well, for hooded seal pups, that’s nothing.
然而 这对于冠海豹宝宝来说 并不算什么
Their mother’s milk contains 60% fat,
冠海豹妈妈的乳汁含有60%的脂肪
the fattiest milk in the world.
脂肪含量为世界之最
For comparison, the richest ice cream clocks in
相比之下 脂肪含量最高的冰激凌
at only 16% fat.
只含有16%的脂肪
And after just three to five days guzzling the stuff,
仅仅豪饮母乳三到五天后
seal pups double their body weight.
海豹宝宝的体重就能翻倍
But seals aren’t the only animals with extreme milk.
但海豹并不是唯一拥有顶级乳汁的动物
动物王国的顶级乳汁
If hooded seals drink the fattiest milk,
如果冠海豹喝的是含脂量最高的乳汁
then tammar wallabies prefer their milk loaded with sugar.
那么塔玛尔沙袋鼠更喜欢含糖量高的乳汁
It can contain as much as 12% sugar,
其含糖量高达12%
more than a glass of Coca-Cola.
高于可口可乐的含糖量
And for a good reason.
这是有原因的
Joeys are born prematurely
袋鼠宝宝属于早产
and finish developing outside the womb.
并且在母亲子宫外完成发育
And since sugars are easier to digest than fat,
因为糖分比脂肪更易吸收
their milk is easier on their developing digestive systems.
所以其乳汁更易被幼崽发育中的消化系统吸收
Meanwhile, the milk also contains antibiotic
同时 袋鼠乳汁中也含有
more powerful than penicillin,
一种比青霉素更强力的抗生素
which protects the young joeys from germs
由于幼崽出生时没有功能完善的免疫系统
since they’re born without a fully functioning immune system.
所以这种抗生素能保护袋鼠幼崽免受细菌侵害
Meanwhile, aardvark milk doesn’t contain much sugar,
相比之下 土豚乳汁不含太多的糖分
but it makes up for it with extreme levels of protein.
但蛋白质含量极高
While cow’s milk has a measly 3 to 4% protein,
牛奶仅仅含3%-4%的蛋白质
aardvark milk can contain over 13%,
而土豚奶蛋白质含量高达13%以上
making it among the highest-protein milks on earth,
是世界上蛋白质含量最高的乳汁
giving calves enough nutrition
给幼崽提供充足的营养
to reach 30% of their adult weight in just three months.
仅需三个月 便能长到成年土豚体重的30%
But while aardvarks have some pretty potent milk,
虽然土豚乳汁极其优质
nine-banded armadillos make some special stuff of their own.
但九带犰狳的乳汁也自有特点
By the time the pups are a month old, they’re drinking milk
到犰狳宝宝一个月大时 它们喝的奶水
that contains 10 times as much calcium as cow’s milk.
含钙量高达牛奶的10倍
All this calcium helps the pups develop
所有这些钙质帮助犰狳宝宝长出
those famous armor shells, which are actually made of bone.
众所周知的“盔甲”外壳 它实则是犰狳的骨骼
Next up, flamingos.
接下来是 火烈鸟
That’s right, flamingos.
没错 火烈鸟
Like most birds, they feed their chicks
跟大多数鸟类一样
by vomiting directly into their mouths,
火烈鸟通过反刍来喂养雏鸟
but that food isn’t made of the day’s catch.
但反刍的食物并不是日常的捕食物
Instead, it consists of a substance called crop milk
而是包含一种叫嗉囊乳的物质
because it’s stored in the parent’s crop,
因为它储存在父母的嗦囊中
and flamingos are one of only three birds
火烈鸟是仅有的能产出这种物质的
that can produce this stuff.
三种鸟类之一
But even among our feathered friends,
而即使在这些鸟类当中
flamingo crop milk is special
火烈鸟的嗉囊乳也很特别
because it’s pink.
因为它是粉色的
That’s because the pigments
这是因为
that give flamingos their brilliant coloring
赋予火烈鸟华丽色彩的色素
leach out of their feathers and into the milk.
从羽毛中滤出并渗入嗉囊乳
Now, all this milk might sound like the next health-food craze,
以上种种乳汁听上去好像下一次的“健康食品狂潮”
but there’s a good reason we generally stick to plain old cattle:
但我们还是继续喝牛奶吧
They’re much easier to milk.
奶牛产奶可容易多了
