Hey
I feed mine using broad based plastic dog bowls as young kunes are too small for a normal trough. I have also introduced adult kunes to these which works well as the size of them means the pigs can guard their meal from other pigs and although the adult pigs tip them as they get to the last dregs they dont flip them over.
They are easy to clean and the very big ones cost about £1 each. I find it results in a very calm feeding routine for my pigs as it reduces competition and stress at feeding. Everyone knows the routine and where they go for their dish. They get thrown carrots while they are eating so once they have finished their nuts they just head off for those rather than trying to steal each others dinner. Having said that they are kunes which are a joy to manage compared to many other more typically" pig like" breeds.
If you are still thinking of adding the grass nuts my suggestion would be to have a look at the nutritional breakdown and see how they could compliment your current feeding regime. My breed convert feed into growth to maximum effect for about the first 4 months after which they still have lots of growing to do but the growth rate slows and they begin to lay down fat so for me, finishing a kune for butchering can often be more about trimming down than the traditional approach of fattening up lol
So finishing on grass in summer or grass pellets in winter would work for many kunes. Before the mass production of commercial pigs in the 70's however people were raising outdoor or back yard pigs on a range of foodstuffs from school canteen waste to kitchen scraps. As feeding foodstuffs is now banned most producers are left with little alternatives than to feed concentrates. Not all smallholders feed their pigs that way though, but those who feed alternatives to concentrates probably would admit it on this forum.
The breed I keep survived by grubbing around Maori villages scavenging for bits of leftovers which has resulted in a breed that stores fat well in order to survive on slim pickings and through hard times. The Maoris didnt put too much time into considering the protein content or digestible fibre of what they made available to the pigs lol. Prior to commercial, fast growing, super lean, tasteless pig production that we have today the traditional rare breeds did well on a scant diet of available bits and bobs.
If the grass nuts available near me were cheaper than the sow nuts I would certainly use them to replace grazing in winter. I still think you should consider a trio of kunes next time. Tee hee
