Bovine spongiform encephalopathy (BSE, the scientific name for mad cow disease) is caused by a misfolded protein called a prion. The outbreak of BSE in the late 1980s and early 1990s was caused by the feeding of rendered cattle carcasses back to cattle as a feed supplement. It was thought at the time that the rendering process (which cooks tissues to a high temperature) would destroy any pathogens; unfortunately heat does not degrade the infectious prion. When cattle with the prion died and were sent to rendering, the animal feed made from their carcass also had the prion and the disease spread rapidly through the cattle herd in England.
Since at least 1995, this practice has been strictly banned in the United States; Canada instituted the ban around this time as well but found some producers had stockpiled reserves to Dodge the ban. Canada's rendered feed ban was considered effective starting in 1999. Europe, including England, also instituted this feed ban in the 1990s, and the cases of infectious BSE have dropped dramatically since. In 2011 there were only 29 cases of BSE in the entire world, and most of these were atypical (non-infectious) BSE.

What is sad cow disease?
It's not sad cow disease, it's MAD cow disease. Its a brain disease that can cause irrational behavior in cows.
How do cows get mad cow disease?
Mad cow disease happens when the proteins in the brain of cow become misfolded. This is called prion. In simple words all proteins have to be folded before they can function and when some proteins in the brain become misfolded, such a state is called prions (misfolding of proteins) and it results in mad cow disease.
What was a cause mad cow disease?
yeh when you had a poo ate it then pooed it back out in a cows mouth which made the cow mad so its madcow disease lols :)
How many cows were affected by the latest case of Mad Cow Disease?
At this point, only one cow is known to be affected by Mad Cow Disease in the latest case (which was in April of 2012). The other cows from the same herd as the one known to be affected will be tested for the disease as well.
How many cows are affected with mad cow disease?
Nobody really knows.

What is the relationship between Mad Cow Disease and Creutzfeldt-Jakob Syndrome?
