Possibly - but pigs are fairly hardy, and have very few dietary limitations, so you can often buy very cheap feed, or just let them forage.

Basically - outside of the cost of the land, pork is really cheap to raise, even for small farmers. As low as $0.64/lb for commercial production, and around $2.50/lb for small farmers and families.

Current mushroom production methods are FAR more expensive (just the spore cost can be $0.50 to $1.00 per lb).

This might scale to make it cheaper, but I'd be pretty surprised. Mushrooms require much more intensive care and handling.

Depending on the species used mushrooms can be cultivated very, very, very cheaply. You only have to look at the average cost of agaricus mushroom per lb ($1.5 - $2) wholesale vs processed whole pork per lb ($6- $7) wholesale to see that. Mushrooms also have a much shorter supply chain in terms of inputs and much less water input.

Creating more spores from mushrooms is incredibly easy and cost effective, so is creating liquid culture which is a process that allows you to create huge amounts of mycelial growing base you can then introduce to more growth medium(corn syrup and water that's been sterilized).
