we've long had meat in a can, but now farmers are bringing us meat that has had a scan.
人们很久以前就开始吃罐装的羊肉，这事不新鲜，不过如今农民们弄来的羊肉可是做过ct的哦。
a ct scanner is being used on sheep in a quest to breed the leanest lambs.
ct扫描仪的新用途是给准备生小羊崽的母羊用。
the scans mean producers can breed and sell healthier sheep that produce the leanest meat. it is hoped the
technique will help revitalise the ￡822m-a-year lamb industry, which has seen sales fall in recent years.
扫描后牧民可以哺育并卖出更健康的羊，产出最瘦的肉。大家希望这个技术能帮助提振价值8亿两千两百英镑的羊肉市场。最近几年羊肉的销售一直在下滑。
in the past, farmers relied on an expert eye to pick the best ram in the flock - the one with the highest muscle content and lowest amount of fat.
以前农民们都是依靠经验目测羊群里最好的公羊的，也就是肌肉比例最高而脂肪含量最低的羊。
while some elite breeders have used ultrasound, the ct scanner gives a much more accurate picture, meaning farmers can be certain of breeding lambs with superior genes and up to two kilograms (4.4lb) of extra meat per animal.
相比一些饲养员使用的超声波技术，ct扫描能提供更详尽的图象，使得农民可以确保生出来的小羊崽基因优良，每只羊比一般的同类多长两公斤（4.41磅）瘦肉。
mr sercombe said: 'as farmers i think we have a real duty at this moment in time to produce food more efficiently.
塞科姆说：“作为农民我认为有责任以更高的效率生产食物。”
'i think we have a duty to the general population to produce faster growing, more muscled animals that use less resources and have less impact on the climate.'
“我想我们对公众负有责任，用更少的资源以更快的速度生产出更多的肉，对气候产生更小的负面影响。”
