Old Scientist: Separating the sheep from the sheep

What sort of high-tech innovation would you expect to see coming out of New Zealand? Livestock looms large in February issues of New Scientist past

WE ARE not in the business of endorsing stereotypes, but few will be surprised to find that the nation exporting the greatest number of sheep pelts is New Zealand. But don’t assume that when you’ve seen one pelt, you’ve seen them all. Some sheep have thinner skin, some have scars from illness or trauma, and lots of pelts have holes from tick bites. In our 3 February 1996 issue we reported that Industrial Research, a state-owned New Zealand company, had come up with a machine that could laser-scan pelts, spot the imperfections and help to grade the skins accordingly.

Uniformity in livestock isn’t all good, though. A report in described how the UK’s chickens had way too little genetic diversity. This paved the way for bacterial infections – once one chicken went down with the lurgy, so did the rest. Surprisingly, no programme to increase genetic variation was proposed. Instead, a consumer organisation demanded stricter inspection of chicken feed – a significant source of infections.

Of course, there would be no need for checks on pelts or food if only scarred sheep and sick chickens were set free. Our 11 February 2006 issue reported that animal rights activists were getting bolder and more violent, and that the US had recently amended a law to explicitly ban “animal enterprise terrorism”. Hen sheds were not specifically the target of the attacks, nor sheep farms, nor even animal research laboratories. The activists had turned their attention to companies merely doing business with those responsible, in their view, for animal suffering. Even people making chicken feed or pelt-scanning lasers might need to watch their backs.
