Mammalian and avian animal proteins (either processed or unprocessed) must not be included in animal feed. This includes animal meat meal, animal fats, meat and bone meal, offal meal, feather meal and any other animal protein or by-products, including catering waste. The only exceptions are: milk and milk products, eggs and egg products but no closed loop feeding of species i.e. eggs to chickens. Care is needed especially when including by-products that these do not contain any of the above.
