Alex again repeated a common misperception, Tuesday 21 September, that Mad Cow Disease (BSE) was caused by feeding bone meal to cows. Mark Purdey, British organic dairy farmer demonstrated with peer reviewed articles, that BSE was caused by government mandated organosphosphates. They cause toxic overload and mineral depletion that results in prion formation. He won a lawsuit against the British Government stopping him and other organic farmers from having to use organophosphates. "Co-incidentally" no organic beef got BSE in the UK, even tho they routinely were meat and bonemeal in their feed.
You can read his research on the Weston A Price Foundation: http://westonaprice.org/myths-a-truths.html
And at his website: markpurdey.com
He wrote Animal Pharm, which covers the entire event: http://www.markpurdey.com/mark_purdey_the_book_animal_pharm.htm
Alex is also wrong that cows are vegetarians. They consume massive quantities of insects whilst grazing pastures, so are partial omnivores. They also absorb saturated fats well, because their guts convert cellulose into short chain fatty acids, meaning that nutrition absorbed from their diet is about 80% saturated fats, as is the case with other ruminants.
The BSE crisis was used not only to justify a animal police state, but also to replace traditional feeds based on natural animal protein with genetically modified soy protein, which is toxic to cows. Cows on rich pasture do not need additional protein because they get everything they need grazing, but confinement cows need additional protein because grains do not provide enough nutrition to create growth. The same occurred with other animals, with most pigs and chickens now being fed GM soy.
Here's an article about how chickens are omnivores, which provides alternatives to toxic soy protein feeds: http://www.westonaprice.org/farm-a-ranch/1971-chickens-are-omnivores-its-no-dilemma.html
Incidentally, Mark's studies of wild incidents of TSE (chronic wasting disease) confirmed elevated levels of barium and silver salts in the carcasses that could be traced to elements used in cloud seeding. This resulted in the same toxic overload and mineral depletion. Heavy metals result in mineral depletion. This can be seen in part 4 of the Weston A Price Foundation link, above.
Many British farmers do not believe it a co-incident that Mark Purdey died soon after from a rapid cancer.
