Research on feeding rabbits is rather limited in relation to that of other domesticated animals. Still, something or other is known. Suitable rabbit feed contains ...
between 2400 and 2800 kcal DE (Digestible Energy) per kg of diet. A higher energy level may cause microbial overgrow of the caecum, causing diarrhoea. Rabbits can be rather sensitive to diseases of the stomach (enteritis and diarrhoea).

The rabbitÂ’s microbial fermentation takes place in the caecum, after which is consumes the content of the caecum (coprophagy). This normally occurs once or twice a day, especially during the night. This way, rabbits obtain a source of microbial protein as well as all vitamins B.

The main ingredient of rabbit feed is often alpha flour or other high-fibre nutrients. Fibres are not digested efficiently by rabbits. Their strategy is to excrete fibres quickly. Other components are fermented in the caecum, followed by coprophagy.
The recommended protein requirement is 16% for maximum growth and 18% for lactation. Calcium is digested efficiently by rabbits. A surplus of calcium is not excreted in the faeces but in the urine, giving it often turbid.
