Capital for swine business depends in the number of sow or pigs you want to raise. Older studies suggest that capital for 1 sow is around 40thousand. This include housing, animal etc. To be safe adjust this to 50t per sow.This computation is up to the time the animal will become pregnant, farrowed and your piglet be sold.
If you intend to keep your piglet and raise it as a slaughter hog you need an additional 3500-4200 per animal for feeds and around 2000t per animal for pen construction.
I would send you an simple cost and return. To give you an idea.
