Pellets

Pellets provide rabbits some more nutrients but are not vital to a bun's diet. There are many rabbit owners who feed their rabbits a pellet-free diet due to teeth problems, chronic GI issues, and obesity. We recommend that you feed at most 1/8 cup to 1/4 cup of pellets per rabbit per day for every 5 lbs of bun. Too much pellets can lead to obesity and a lack of adequate hay consumption.

Type
The type of pellet (alfalfa or timothy) fed usually depends on the age of your rabbit. Alfalfa pellets for buns under 7 months old, and timothy pellets for over 1 year old. However, it ultimately depends on the nutrition values listed on the back of the bag. Most commercial alfalfa-based brand pellets will have more calories and less fiber than a timothy-based brand.

Dana Krempels, Ph.D., recommends that a good pellet should have the following qualities: Both alfalfa and timothy-based pellet brands can come close to these recommendations.
 * at least 22% crude fiber
 * no more than approximately 14% protein
 * about 1% fat
 * about 1.0% calcium.

Good pellets do not include dried fruit, seeds, nuts, or other colored crunchy things. There should be only pellets and maybe hay and nothing else. Not of these additions are healthy for a rabbit, as they are strict herbivores, and in the wild, they will not obtain dried fruits and nuts and other starchy foods. As Krempel states, "The complex flora of the cecum can quickly become dangerously imbalanced if too much simple, digestible carbohydrate is consumed--especially if the diet is generally low in fiber. The result is often 'poopy butt syndrome,' in which mushy fecal matter cakes onto the rabbit's behind. This a sign of cecal dysbiosis, which can foment much more serious health problems."
