Hi Jacob,
These are not the costs for my pigs, this is just an example spreadsheet.
The food i used was Heygates Growth Pellets 20KG £5.67 per bag, but you can get a 30p discount per bag if you order 25 bags. For our 7 pigs we will have got through approx 60 bags of food, plus i got a sack of bread from the butcher every fortnight, and because we were soppy we would buy them apples,bananas and brocolli when it was reduced along with any milk that we could get reduced, so probably spent an extra £50 over the course of time.
Tomorrow i will try and put the full costs up
