In this context, I believe it’s fine to reveal the actual product name, since it’s concerning whether it’s suitable for your rabbit or not, rather than being an overt advertisement/promotion. I appreciate both of your respects to the forum guidelines.
I suspect you’re using the Burgess Rabbit Junior/Dwarf Pellet brand, based on the nutritional break down.
There may be a fact for the metabolism of a smaller breed being faster, but I then think about humans — those with higher metabolisms don’t need to eat differently than those who don’t. Nutrition needs are still the same. I am leaning towards the brand potentially trying to make some more money by categorizing their product more as specialized (similar to a pasta sauce brand selling 500 varieties, rather than just 1). Unsure. There could be legitimate empirical research done about the product which does show it helps dwarves, but many dwarves have lived long, wonderful lives without breed-specific food.
In terms of it harming your rabbit, your rabbit is at the age where you can actually change to “adult” pellets. If the pellets you’re currently using are for junior/dwarf breeds, you can begin switching to the adult version, which has a slightly different nutritional make-up and will have Timothy Hay as the primary ingredient, rather than alfalfa, which is more typical of young-rabbit pellets. It should not do harm to your rabbit, since all rabbits, regardless of breed, should have the same diet!
