Can I graze cattle in a field which is immeadiately next to a pet food factory? They produce a raw meat dog food.The field and site share a common entrance. The field will be fenced off from the unit.The person renting the unit is saying,"defra won't like this" etc etc and is starting to give me grief. I have been given the use of the field for a cut of silage/ hay and also grazing afterwards, Angus.
