American scientists say they're hopeful of cloning cattle resistant to BSE, or mad cow disease, in the next 10 years.
Work has begun to identify and remove a protein found in the nervous and immune systems of animals, which is essential in the development of diseases such as mad cow and scabies.
Dr Will Eyestone, from the Virginia Maryland College of Veterinary Medicine, says if the protein can be removed, they could be left with an animal incapable of developing mad cow disease.
He says the research could then be applied to cloning bulls for breeding.
'This is certainly no quick fix here, but it certainly does provide one possible way of ensuring the cattle that are provided for human consumption would be free from mad cow disease, and certainly that has attractive and positive aspects.'
