It is based on the "Over Thirty Months Rule" introduced in the UK on 3 April 1996, as one of several measures to manage the risk associated with bovine spongiform encephalopathy (BSE). By November 1997, about 1,772,000 cows had been slaughtered under the scheme, with compensation of 1 ecu per kg, reduced to .9 ecu in October 1996, and later to ...
This cow with BSE displays abnormal posturing and weight loss. Signs are not seen immediately in cattle, due to the disease's extremely long incubation period. [ 12 ] Some cattle have been observed to have an abnormal gait, changes in behavior, tremors and hyper-responsiveness to certain stimuli. [ 13 ]
The result was bovine spongiform encephalopathy (BSE), also known as "mad cow" disease. [9] The number of cases, initially low at the end of 1986, increased rapidly. By mid-1988, there were 50 cases a week, rising to 80 cases a week by October of the same year.

Grain-fed cattle have more internal fat (i.e., marbling) which results in a more tender meat than forage-fed cattle of a similar age. In some Asian countries such as Japan , which is not a grain-surplus country, tastes and preferences have encouraged feeding grain to cattle, but at a high cost since the grain must be imported.
When BSE was identified, the United States banned the importation of British cattle in 1989, and 499 cows who had been recently imported from the United Kingdom were killed. The United States slaughtered an additional 116 British cows in 1996. [28] Between December 1997 and November 1999, the British government banned the sale of beef on the ...
TSEs in non-human mammals include scrapie in sheep, bovine spongiform encephalopathy (BSE) in cattle – popularly known as "mad cow disease" – and chronic wasting disease (CWD) in deer and elk. The variant form of Creutzfeldt–Jakob disease in humans is caused by exposure to bovine spongiform encephalopathy prions. [4] [5] [6]
