President contracted cow disease (5)

Ross

I believe the answer is:

hoove

I'm a little stuck... Click here to teach me more about this clue!

'cow disease' is the definition.
I know nothing about this answer so I cannot tell whether it can be defined by this definition.

'president contracted' is the wordplay.
'president' becomes 'hoover' (I've seen this before).
'contracted' means to remove the last letter (to contract is to shorten).
'hoover' with its final letter taken off is 'HOOVE'.

Can you help me to learn more?
