As we need to see the ingredients, I’ve looked it up on the website and zoomed in as best I can - it really didn’t zoom very well!
From what I can make out, I’d probably not feed it as it isn’t what I look for in a forage - it looks like it contains things like Lucerne (alfalfa) which should be avoided, and sunflower meal. Wheat meal etc.
I buy forage from Piggie Parcels which is a business run by a member of this forum. All the forage is purely safe leaves, flowers and veg in either mixed bags or individual bags so you can buy just the things your piggies love - mine really liked dried plantain and raspberry leaves in particular!
