The letter of the law from DEFRA:
Current legislation also imposes strict controls banning the feeding of other
materials of animal origin or products containing them to farmed animals.
There are however a small number of exceptions to this, and the following
materials may be fed to pigs:
• Liquid milk or colostrum may be fed to pigs kept on the same holding
as that on which the milk or colostrum originated;
• Former foodstuffs other than catering waste food from kitchens etc
(see above) containing rennet, melted fat, milk or eggs but where these
materials are not the main ingredient;
• Fishmeal, (animal derived) di-or tri-calcium phosphate, or blood
products if suitably processed (see TSE Regulations internet link
below); and
• Milk, milk products and white water when suitably treated.
Please note that anyone obtaining waste milk, milk products or white water to
feed to their pigs would need to register with Defra for this purpose, although,
in the case of milk products, this would only be necessary it they contained
more than 80% milk. Details on how to register are available from either the
Defra helpline (08459 33 55 77) or the internet (
