Tummy time 🐰🐹
Rabbits are known as “hind-gut fermenters”. Instead of digesting their food in their stomach and small intestine, microbial fermentation occurs in the caecum and large intestine (colon).
Large amounts of fibre are needed in their diet to keep the gut moving. When the fibre reaches the caecum and large intestine, it is separated into non-digestible fibre, which is quickly expelled in small hard pellets, and digestible fibre. The digestible fibre and other nutrients form soft caecotrophs, which are eaten again by the rabbit directly from their hind end! This usually happens at night, and hence is called the “midnight snack”.
Guinea pigs are also hind gut fermenters and practice “caecotrophy” but less is known about this.
The main thing to remember is that fibre is key, so always offer plenty of good quality grass hay to your pet, and ensure pellets, treats are supplements are hay based. Find out more about Oxbow’s range of products at https://www.oxbowaustralia.com/oxbow-grass-hays/
