This won't help you now, but next year towards August and September, plant some winter wheat and rye grasses for the goats. If your goats are still going out to pasture then they're probably finding clover and fescue to eat right now, so they're likely not 100% reliant upon feed. I don't have any experience with pigs, so I'm no help there. Growing up, I know my mom always saved kitchen/table scraps for the pigs, but I'm not sure what's safe and what isn't.
