Hiya

just coming in to add my tuppenceworth too

If you
want to buy a pig arc and have the spare cash, by all means get one - it'll be a sound invertment and last for years to come, But, you don't
need one ! Pigs will get by spring to autumn in very basic housing (I once bought weaners from a lady who made an arc from palletts with a few feed bags over the top to keep the rain off - basic and not the prettiest thing to look at, but it did the job without costing the earth)
It might be prudent to wait til you're certain pigs are going to be a permanent addition before committing to the cost of the arc ? Plastic is said to have better insulation properties than the metal, but ours are metal and the pigs are fine in them.
Pig's who graze......
I keep Kune Kunes and it's true that they graze and don't root (as badly) as other breeds. Those not kept for breeding can maintain themselves on grass and a bit of fruit and veg through the summer, but they still need feeding in the months when there's not much grass. If they are for breeding or if they're under a year old they should be fed at least 1lb of hard feed daily (they need the vitamins, minerals and protien for good bones and long term health) So they don't survuve on grass alone I'm afraid

Large Blacks are another breed I keep and I definately wouldn't use the term 'grazer' more 'browser/forrager' they do eat grass, and roots, and big lumps of earth as they dig it up

but I wouldn't say it's 50% of their diet, more like 20% - ours still get 5lbs of food a day, even when the grass is in good supply - they're not over fat pigs either

. I think on half rations of pig food you'd have very hungry pigs who would be either very vocal or escaping looking for food and longer term you'd find they took longer to finish or had problems when it came to breeding.
Don't keep Saddlebacks, so can't comment on them really - but I suspect they're the same as the Large Black.
Try and read as much as you can and visit forums for advice - it's good to get as many viewpoints as possible and use the experiences of folk who are keeping them already. Everybody has their own way of doing things (as it should be, cos we've all got our favourite breeds and different set-ups to consider) pick and mix to find what works best for you, but just don't scrimp on the feeding
