USA -mini cows could save the planet
27/7/2010 Guardian Miniature cattle could be the future of environmentally-friendly beef.In the US, where around 30kg of beef is eaten per person each year, farms are
ditching Holsteins and Aberdeen Angus for their smaller counterparts, and there
are now well over 20,000 mini cows in the US. Professor Richard Gradwohl is
responsible for 18 new breeds of miniature cattle on his Seattle farm, including
a Miniature Panda – a fluffy eye-patched little cow just 107cm high. (His
micromini cattle are less than 96.5cm tall – those shorter than 92cm are known
as “teacup cattle”.)
“When I started frittering around with miniature cattle, everyone thought I was
nuts,” he says. Since the 1940s, US farmers have been breeding cows for size,
making them much larger than their British cousins. But with Gradwohl’s farm
being swallowed up by rising taxes, he had to give up 60 acres of land. He
discovered that it is possible to raise 10 miniature cows on five acres, rather
than just two full-sized cows, meaning that land could yield up to three times
as much beef – but the cows only need one third of the feed.
“These little cows were just right for me,” he says. And, given worries about
cows’ contribution to greenhouse gases, it takes 10 mini cows to produce the
amount of methane of one full-sized cow.
Gradwohl now ships semen, embryos and cattle all over the world – except to the
UK, where 1,400 farmers already breed Dexters, which are 96-111cm tall.
And the mini cows’ beef tastes great. The bigger the cow, the longer the cells
in the muscle are. A shorter cell means more tender beef, so smaller breeds have
naturally better flavour.
Although they sound innovative, mini cows date back to the 1600s, says Gradwohl,
when “British farmers developed small breeds because they only had five-acre
farms”. Now, with a bit of luck, more farmers of the 1.3 billion-strong cattle
worldwide might also try them out for size.
