I’m always here I just lurk in the background listening 🙂
Unfortunately like everything both we and the animals eat it’s being messed with.
I think like us they need a mixture of foods and not one thing as that is what they would do in the wild.
One year when I only fed small dog biscuits ( royal canin so nothing cheap ) to my overwintering hogs some of them started to get a little thin on prickles ( and it wasn’t ringworm/mites etc ). I added various other things as well as a zinc supplement and the problem reversed very rapidly on all of them.
Oh and by the way some of my rescues and wildies like dried banana and other fruits. Again I suspect things they may take a bite of in the wild on their travels ( although perhaps not the banana lol ) But again tiny quantities in a very varied diet
