Chinese Scientists Create Genetically Modified Low-Fat Pigs (npr.org)

Chinese scientists have created low-fat pigs using new genetic engineering techniques. "In a paper published Monday in the Proceedings of the National Academy of Sciences, the scientists report that they have created 12 healthy pigs with about 24 percent less body fat than normal pigs," reports NPR. From the report: The scientists created low-fat pigs in the hopes of providing pig farmers with animals that would be less expensive to raise and would suffer less in cold weather. The animals have less body fat because they have a gene that allows them to regulate their body temperatures better by burning fat. That could save farmers millions of dollars in heating and feeding costs, as well as prevent millions of piglets from suffering and dying in cold weather. The Chinese scientists created the animals using a new gene-editing technique known as CRISPR-Cas9. It enables scientists to make changes in DNA much more easily and precisely than ever before. Pigs lack a gene, called UPC1, which most other mammals have. The gene helps animals regulate their body temperatures in cold temperatures. The scientists edited a mouse version of the gene into pig cells. They then used those cells to create more than 2,553 cloned pig embryos. Next, scientists implanted the genetically modified cloned pig embryos into 13 female pigs. Three of the female surrogate mother pigs became pregnant, producing 12 male piglets, the researchers report.

      That's the first thing I thought about when I read this, less flavor in pork.

      We've already killed beef off with flavor, having less and less intramuscular fat.

      You look at a picture of a Prime cut of beef from the 50's even to the late 60's compared to today's "prime" cuts, and you see a HUGE difference in fat content.

      That fat is flavor.

      I call bullshit on your heart disease post. My grandmother ate bacon all her life, and for most of her life she cooked with LARD. Yes, lard, that fat from hogs. Nearly everything tastes better when cooked with real fat - biscuits, fried chicken, cakes, etc.. Note that my grandmother lived to within months of her 90th birthday. How long is your skinny ass going to live?

      It's lifestyle, not diet. She led a life filled with physical work, rarely ever saw a doctor, and was taking no prescription medicines. Hell, she worked outside doing yardwork the day before she died. Her mind was still as sharp as a tack. What's your excuse?

      I am 64, soon to be 65. My blood pressure, cholesterol, and blood sugar are all normal. I eat bacon and a lot of other "unhealthful" food, but I also lead a lifestyle that involves a LOT of physical activity.

      I have 3 more anecdotes to add to the pile. They were all people that never bought into any sort of new age diet nonsense. They also lived into their 90s.

      It's probably not even "life style". It's genetics.

    That's a lot (196) of embryos per pig. The female pigs would have exploded if the embryos had all been viable.

    At least the piglets look cute.

    The animals were slaughtered when they were six months old so scientists could analyze their bodies.

    Pigs can't burn fat for warmth (according to the summary).

    Because of this the only defense against cold pigs have is accumulating more fat, and small/young ones die.

    This modification means they require less fat to regulate body temperature, and burn more when it's cold (which is why they are leaner).

      No seriously though, the UK and colonies tend to eat cuts of bacon with the loin and back, whereas in America and continental Europe they tend to go for the streaky cut. There is far less fat in the loin and it is (in my opinion) more delicious.

      Well, it's called streaky bacon in the UK apparently.

      Anyhow, what I've never understood is why Americans take the fatty bacon cuts then basically cook off all the fat - leaving the bacon hard and crispy, but lacking all the fat that the cut had. Granted, good chefs save the bacon fat that's now on the pan for further cooking, so flavoring the stuff cooked afterwards, but it always struck me as odd.

      Yes, I don't particularly like hard crispy bacon - when I get bacon (the streaking american kind) I always halve the cooking time so it gets nice and hot and fat just starts to run out, but the slices are nice and moist and limp and oh-so-tasty. Bacon bits never really appealed to me - it's just like jerky.

  9. and why this isn't a good idea by MrKaos · · Score: 2

    I used to go hunting a lot. Feral pigs (or boars) are super aggressive and destroy the area they are in. You need a reasonably large caliber rifle to kill them, they breed like crazy and are full of worms so you can't eat them. They will attack humans, are smarter than a dog and boars can grow pretty big - you would not want to mess with one unless you had a weapon.

    *Anything* that can potentially get into the wild, like a genetically engineered pig that can survive cold, is a really, really bad idea. Expect at least one of these pigs to escape and breed in the wild.

    This is an extremely short sighted endeavor.

      I can't quote you which publication was that now (Bloomberg businessweek?), but it there was a article a few years ago about the result of selective breeding of cows, both the physical shape of the cow and fat content of the beef in the commercial range of western world is very different from now. But whatever fat content lowered in the beef in the 2010s, people compensate by slathering butter, BBQ sauce and seasoning imaginable to make it more palatable. Thus there are no obvious lowering of calorie count - if fact, it may be slightly worse for health due to the sugar content and chemicals in artificial additives.

    Yeah, because proper Spanish pork is "low fat".

    It only seems to be America where pork is supposed to be "the other white meat". This fixation doesn't seem to exist anywhere else in the world (at least until now). Other European pork also doesn't seem to have this low fat tasteless quality.

    "The other white meat" needs to die a fiery death.
