I completely agree. 25% crude fiber is excellent. I think only Oxbow and Supreme Science Selective has that. For an adult bun, 14% protein is great. A baby/youngster under 6 months needs more protein, but for adult buns, I prefer 13-16%.
Rabbits should have a hight-fiber, low calory diet. Thanks to their big cecum and the gut bacteria at work in it, they are expert at extracting nutrients from their food. This is an evolutionary adaptation that enables them to live under very meagre conditions in nature. They are selective eaters, meaning they go for the food that has the most calories first – they often get interrupted by potential dangers while they graze/forage in the wild, so it’s a good strategy. But this means they will eat high calory, nutritionally dense food if given the chance and in captivity, those chances could be far too ample for their own good.
A bunny’s ideal diet should be at least 80% grass hay. Oxbow pellets are very good, but as all pellets, they should be fed in moderation.
