How To Reset Eminent Suitcase

Raising 'mini-cows' to reduce emissions

U.S. Some farmers raise cows in miniature - of between 80 centimeters and one meter or so - to reduce emissions of methane, because these animals emit a smaller amount of this gas the smaller, according to a study by the farmer and researcher Richard Gradwohl.

Gradwohl (pictured with one of these animals) developed in its research center 16 of the 26 races of 'mini-cows "that exist worldwide, although its initial target was to cover the needs of seven different markets, including one of the key is to pets, according to the BBC.

Thus, after years of study, the farmer discovered that this species miniature emitted lower amounts of methane - a greenhouse gas - than larger ones. "After researching many years, we found that produce much less methane," he says while pointing out that ten mini cows produce the same amount as a large one.

In this sense, Gradwohl points out that if this fact is added that in an area of \u200b\u200bfive hectares - which would come two big cows - enter ten of the 'mini' in the end, each hectare has a higher yield per kilo of meat.

This higher yield is obtained because the relationship between live weight and the amount of edible meat is not the same in a large species than small. "When an animal of 450 kilos to the slaughter, lost nearly 40 percent. It is then a response of 270 kilos and when you turn it into edible meat lose another 20 percent end up with 216 kilos," he says.

Meanwhile, in a miniature cow "you lose a lot less." "If the cow weighs about 270 kilos, when going to the slaughterhouse instead of losing 40 percent lost 30 percent and when you make what is edible meat, instead of 20 percent, losing 15 percent. Then, a small animal can produce up to 160 kilos of edible meat, "he adds. The figures are due to the small bones are smaller and have less fat.

Finally, Gradwohl says that the flesh of 'mini cow' is even more delicious as the taste is related to muscle length. "The shorter, richer meat. In that respect is similar to beef," he says.
