Bug-fed steak
虫饲牛肉
Insects could help turn beer waste into beef
啤酒废料变牛肉? 昆虫来帮忙
People do not like eating insects.
Livestock are less picky.
人不喜欢吃昆虫。畜生就没那么挑食了。
EATING INSECTS is one of those ideas that never quite seems to catch on. The United Nations endorsed the idea a decade ago, but, in the West at least, bugs remain mostly absent from supermarket shelves. Faced with an indifferent-or disgusted-public, scientists have been exploring other options. One is to feed the insects instead to livestock, which are not so picky.
有些想法一直没有真正流行起来，吃昆虫就是其中之一。尽管联合国十年前就认可了这一想法，但至少在西方，昆虫基本上还是没有摆上超市货架。面对对此不感兴趣甚至感到恶心的民众，科学家们一直在探索其他选择。一个选项是把昆虫喂给不像人那么挑食的牲畜。

Of course, the insects need to eat, too. To date, they have mostly been reared on leftover chicken feed. But the supply of that is limited, and if insect-reared meat is to take off, new sources will be needed. In a paper in Applied Entomology, Niels Eriksen, a biochemist at Aalborg University, suggests feeding them on the waste products of the beer industry.
当然，昆虫自己也需要吃东西。到目前为止人们大多用鸡吃剩的饲料来喂养昆虫。但这钟饲料供应有限，如果要让用昆虫饲养家禽这一产业蓬勃发展，就需要新的饲料来源。丹麦的奥尔堡大学 (Aalborg University) 的生物化学家尼尔斯·埃里克森 (Niels Eriksen) 在《应用昆虫学》(Applied Entomology) 上发表了一篇论文，建议用酿啤酒的废料喂养昆虫。

Entomology /ˌen.təˈmɒl.ə.dʒi/昆虫学
The world knocks back around 185bn litres of beer every year. Each litre produces between three and ten litres of wastewater full of discarded barley and yeast. The mix is rich in protein but deficient in carbohydrates especially compared with chicken feed. Most insects grown for feed depend, in the wild, on the carbonhydrates found in rotting fruit. Whether insects would actually consider brewery waste a square meal was, therefore unclear.
全世界每年消费约1850亿升啤酒。每酿造一升啤酒会产生三到十升废水，其中充满废弃的大麦和酵母。这种混合物富含蛋白质，但缺乏碳水化合物一一尤其与鸡饲料相比。大多数可用作饲料的昆虫在野生环境中都靠腐败水果中的碳水化合物生长。因此，不清楚昆虫是否真的会把啤酒废料当作丰盛美食。
knock back
to quickly drink something, especially a lot of alcohol一下子喝下（尤指很多酒）
She was knocking back the champagne at Maria's party.她当时正在玛丽亚的聚会上畅饮香槟。
litre （度量单位）升The tax increase will add 4p to a litre of petrol.税率上调后每升汽油要涨4个便士。
discardto throw something away or get rid of it because you no longer want or need it 抛弃，扔掉
Discarded food containers and bottles littered the streets.街上到处都是被丢弃的食品包装和瓶子。
yeast /jiːst/ 酵母；酵母菌

The researchers used the larvae of the black soldier fly, a workhorse of the "entomoremediation” world.The juvenile insects were divided into three groups, which were offered beer waste, chicken feed or a mixture of both. The researchers monitored both their weight gain and the amount o carbon dioxide they exhaled, which helped assess the insects' metabolic performance.
研究人员使用了黑水蛇的幼虫，它们是“昆虫修复”领域的主力军。这些幼虫被分成三组，分别喂给它们啤酒废料、鸡饲料，以及两者的混合物。研究人员监测了它们的体重增长以及呼出的二氧化碳量，这有助于评估它们的代谢情况。

幼体，幼虫
black soldier fly
黑水虻，腐生性的水虻科昆虫，能够取食禽畜粪便和生活垃圾， 生产高价值的动物蛋白饲料，容易管理、饲养成本低，动物适口性好等特点，从而进行资源化利用，其幼虫被称为“凤凰虫”，被广泛应用于处理鸡粪、猪粪及餐厨垃圾等废弃物方面。
metabolic

metabolic rate (= the speed at which their bodies
used energy).
这些运动员为加速新陈代谢而服用了药物。
The larvae happily consumed both brewery waste and chicken feed, and grew equally well on either food source. When Dr Eriksen ground some up and chemically analysed the resulting paste, he found few differences in how nutritious the insects would be to farm animals. The results confirmed one of Dr Eriksen's hunches. Although black soldier fly larvae favour rotting fruit in the wild, they are capable of eating carrion too. Like beer waste, it too is rich in protein and low in carbohydrates
这些幼虫不论是啤酒废料还是鸡饲料都吃得很欢，并且不管吃的是其中哪种，都长得同样好。埃里克森把一些昆虫碾碎并对得到的糊状物进行化学分析。他发现对于牲畜而言，不同组别的昆虫的营养价值几乎没有差别。这一结果证实了埃里克森的一个直觉。虽然黑水蛇幼虫在野生环境下喜欢吃腐败水果，但它们也可以吃腐肉。和啤酒废料一样，腐肉也富含蛋白质，且碳水化合物含量低。

hunch
an idea that is based on feeling and for which there is no proof 直觉；预感

carrion
dead or decaying flesh 腐尸；腐肉
The experiment may have implications beyond the brewing business, too. Bone meal from slaughter houses, sugar-beet waste and waste from other fermentation industries (such as those that produce biothanol) are all likewise plentiful and protein-rich. All now look to be reasonable targets for nutrient recycling by insects. Whether consumers will be willing to eat insect-reared beef, though, remains to be seen.
这项实验的影响可能不止于酿酒业。屠宰场的骨粉、甜菜废料以及其他发酵工业 (比如生产生物乙醇)的废料都同样供应充足且富含蛋白质。现在看来，所有这些似乎都可以被用于通过昆虫做养分循环。不过，消费者是否愿意吃“虫饲牛肉”还需拭目以待。
