Using pet food, animal feed, and nutritional supplements
Find out the requirements for feeding pet food, animal feed, and nutritional supplements to your animals.
Requirements for using oral nutritional compounds
Pet food, animal feed, and nutritional supplements for animals are classed as oral nutritional compounds. When you feed them to your animals, you must comply with the requirements set out in regulations.
How to use pet food, animal feed, and nutritional supplements
When you use an animal feed (including pet food) or supplement, you must be confident that it's fit for purpose. This is a requirement under Regulation 8.
We recommend that you:
- try to confirm the product's fitness before feeding it to animals
- do not buy a product if you're not sure whether it's fit for purpose
- do not use a product if you're not sure whether it's still fit for purpose
- follow the instructions on the label
- use the product as recommended by the manufacturer.
If you don't follow the instructions on the product's label, or if you make changes to the product, you must make sure:
- the product is still fit for purpose, and
- it's not likely to cause any of the harms listed in Regulation 7(a) to (h).
Note: If you make your own animal feed (including pet food), you're fully responsible for its fitness.
