17-20% fiber in the goat feed isn't bad--lots of rabbit pellet brands are in that range. The 10% fiber in the sheep feed is way too low.
What jumped at me is the vitamin A. Those are many times the vitamin A levels that are found in rabbit pellets. Over-dosing added vitamin A can cause problems. My guess is that the manufacturer is adding retinol for a vitamin A source---that is the source that can cause problems if overdosed. You would have to call them to find out. (if the vitamin A source is beta-carotene, it might be OK. My understanding is that there isn't an overdose problem with beta-carotene).
Nutrition is complex. If there was a word beyond complex, I would use that word. Amateurs (like me) probably don't take all the variables into account.
