Ok, I got this off of RabbitsOnline forum:
"Fruit should be regarded as a treat item and fed in limited quantities only as it is high in simple sugars and can lead to gastrointestinal disturbance and dental caries."
"Sudden changes in diet must be avoided. Any change in diet should be made gradually over several days to weeks, starting with small amounts of the new item and gradually increasing them, whilst making a corresponding decrease in the unwanted item if necessary. Ad lib hay should always be available, and it is especially important to ensure that weanling rabbits eat plenty of hay...."
"Green foods are also important and a variety should be fed daily to rabbits of all ages. They should be introduced gradually to weanling rabbits. Examples are broccoli, cabbage, chicory, chard, parsley, watercress, celery leaves, endive, raddichio, bok choy, dock, basil, kale, carrot and beet tops. Wild plants can be given if available, e.g bramble, groundsel, chickweed, dandelion. All green foods should be washed before feeding."
Here's the link I found this information: (broken link removed)Removed - we do not allow links with breeding how-to info or those celebrating breeding.
They have alot of good information on rabbits (even though they do have a section on breeding) and are a very knowledgeable group. Good luck.
