I've just found this feed info, thought I'd share:
A Good Rabbit Diet Should Include Daily Fresh Vegetables, include a variety of vegetables from the list below.
(Those containing a high level of Vitamin A are indicated by an *. Feed at least one of these each day.)
Alfalfa, radish, and clover sprouts
Basil
Beet greens (tops)
Bok choy
Broccoli (mostly leaves/stems)*
Brussels sprouts
Carrots and carrot tops*
Celery
Cilantro
Clover
Collard greens*
Dandelion greens (NO pesticides)*
Endive*
Escarole
Green peppers
Kale
Mint
Mustard greens
Parsley*
Pea pods (the flat edible kind)*
Peppermint leaves
Radicchio
Radish tops
Raspberry leaves
Romaine lettuce (NO iceberg or light
colored leaf lettuce)*
Spinach
Watercress*
Wheat grass
Kale, mustard greens, and spinach contain high levels of oxalates (the salts of oxalic acid), which can accumulate in the system and cause toxicity over time. Rather than eliminating these veggies from your list (because they are highly nutritious and loved by most rabbits), limit your use of them to 1 or 2 meals per week.
Chewing items: In addition to nutrition, hay and vegetables are also important to your rabbit’s dental health. A diet that requires little chewing produces uneven tooth wear, causing enamel to grow on the sides of the teeth. These spikes can cause severe oral pain and excessive salivation (often called “slobbers”). They also cause reluctance to chew, inability to close the mouth, and reduced food intake. The situation deteriorates as the teeth continue to grow, and, if it is not treated, results in severe malnutrition. In addition to hay and vegetables, you will want to provide your rabbit with chew sticks or gnaw “bones” of untreated wood of various sizes and shapes. Cardboard tubes and untreated wicker can also be used.
Treats, including fresh fruits, should be given sparingly because of their calorie content. Rabbits can digest small quantities of oats and barley, but again, they generally provide more calories than necessary. And, too much carbohydrate has been associated with enteritis in rabbits.
Like human beings, rabbits need to be fed differently at different stages of their growth to ensure healthy development, digestion, and weight. Throughout a rabbit’s life, avoid any sudden changes in diet; new foods should always be introduced gradually.
Remember to keep fresh clean water available at all times, too. Water bottles versus dishes are recommended.
