Zinc supports immune function, wound healing, skin integrity, and coat health. It plays a role in over 300 enzyme reactions in the body. Guinea pigs with adequate zinc tend to have healthier, shinier coats and faster wound recovery.
Typically provided through hay, pellets, and varied vegetables.
Poor coat quality, slow wound healing, skin lesions, reduced immunity.
Very high zinc can interfere with copper absorption. Not a concern from food alone.
