hau James and welcome to hog raising. The KuneKune is a semi lard hog that will reach around 300 lbs. in weight. Normally "feeder" pigs are pinks or other large growing hogs.
the KuneKune is a pasture hog, very similar to our American Guinea Hogs (a true lard hog) they are going to prefer grasses and weeds for their food source and that makes them pretty cheap to feed since all you need is pasture
land.
To keep them from destroying their pasture, you will want to move them around very frequently so they don't eat all the grass to the
roots, also you will need to let that area rest for at least a month or two to recover.
Use a good hog grower food as a supplement and any fruits, vegetables you can. I would recommend against giving them any meat or meat scraps, offal, etc.
Potatoes would need to be cooked before they can be fed to hogs, they will not eat onions or peppers. Pumpkin is a great thing to feed since the seeds also act as a wormer on hogs.
When you feed them, they
should finish the food within 30 minutes, if it take them longer than that, then you gave them too much food. Hogs can and will get obese and that isn't good for their joints anymore than being overweight is for humans.
Herbs are great food for hogs and many of them do double duty by also being
medicinal.
