H,
TS have a risk based assessment process which picks out some newbies at random together with some old hands and these get visited.
If when they visit they find things wrong, then you get more frequent visits, everything ok and you will go back into the Random pool.
Many pig keepers never get a visit.
Both your medical and movement book can be in any written form (Whilst TS may do versions, you do not need to use them, though it can be simpler just to use them) and can alternately held on computer providing you can print immediately if a surprise visit happens.
TS are generally interested in movement, we have never had our medical book examined - the latter is more an FSA thing, and they don't do visits they rely on random testing at the slaughterhouse.
The vet does not need to sign your medical book.
Medical records come under The Welfare of Farmed Animals (England)
Regulations 2000 (S.I. 2000 No. 1870).
Schedule 1,
paragraph 7 states that:
A record shall be maintained of –
(a) any medicinal treatment given to animals; and
(b) the number of mortalities found on each
inspection of animals carried out in accordance with
any of the following provisions.
Para 45 says
45 Only authorised veterinary medicinal products
should be used. You must keep full records of all
medicines used, including where it was bought. You
must also keep records for at least three years of:
• the date you treated the animals;
• the identity and quantity of medicine used; and
• which animal or group of animals you treated.
