My lot get a handful of 'treat' hays, usually oat, orchard, spelt or readigrass in the evening. Dried forages, nettle, plantain, yarrow, raspberry leaves, apple leaves, willow, cornflowers and dandelions are their favourite. Then they get grassy logs from Galens garden, stuffed with hay or grass or something. I use Fibafirst sticks as treats too sometimes, they quite like those. (not all on the same night, in case it read that way lol)
The most unhealthy treat my lot get are the pansy and apple hearts that Pets at Home sell, they go mad for those, although they only get 1/4 of a heart per pig, once a month or so because I assume they're not all that healthy.
Other than those, a small piece of fruit once a week makes a great treat, melon, berries, apple, or a slice of banana go down well here! A handful of fresh grass grown on a windowsill will also be very well received!
