So if hay makes up 80% of a rabbits diet what about the remaining 20%? 10% of the diet should consist of a good quality, high fibre pellet. There are musli mixes out there that you can buy from the supermarket or a number of pet shops but these are not a great option for your rabbit. With musli mixes rabbits have a tendancy to pick out the pieces they like and therefore do not get all the nutrition they need. With a plain pellet diets rabbits have no choice and must eat the pellets thereforing recieving everything the need nutrition wise. I recommend a pellet diet that is over 16% fibre as rabbits need a large amount of fibre in their diet in order for their gut to work properly. In New Zealand I would recommmend the following pellet foods; Burgess Excel, Oxbow or Kaytee. The one I personally use is Burgess Excel pellets for adult rabbits, this food has 39% fibre and is a vet recommended food that has arrived very recenctly in New Zealand from the UK. It has added mint to aid with digestion and I have had my rabbit on it for the last month or so and he enjoys it and I have noticed a big difference in his energy and food intake since being on it. It is a super cheap option as well costs about 20 buks for a 2kg bags but you should only be feeding about 50g a day or an egg cup full to your rabbit so accounts to a 50c per day cost, lasting an average adult rabbit around 40 days. I have not personally tried oxbow pellets but know they are also a good, vet recommended diet for rabbits though have slightly less fibre then burgess. I have used Kaytee before with my rabbit, it consists of the least beneficial fibre out of the 3 but is still above the recommended amount. I just found this option a little bit unnatural and Dustin didn't really enjoy it as much. As mentioned before a good quality pellet diet should not be overfed, 50g a day for an adult rabbit is plenty :)
