Purina Rabbit diets are formulated to meet the daily dietary requirement for calcium.
Our rabbit feeds contain high levels of alfalfa, which is highly palatable to rabbits and provides an excellent source of fiber. All diets are carefully formulated to contain a specific and constant amount of calcium.
Basically, it makes no difference whether alfalfa or other grass hay is used in the diet. We need to supplement the rabbit’s diet with calcium in the form of calcium carbonate because neither alfalfa nor grass hay contains sufficient calcium to meet the rabbit’s daily needs.
For example, when hay such as timothy is used in the diet, more calcium carbonate would need to be added to the ration to meet your rabbit’s requirement for calcium. Using alfalfa “which has a greater calcium content” means less calcium carbonate is added to meet the needs of your rabbit. Purina rabbit diets are formulated to maintain a constant level of calcium in the diet.
Do not feed alfalfa supplements or other vitamin and/or mineral supplements to rabbits eating Purina’s complete rabbit diets since this could cause a nutritional imbalance that might make your rabbit sick.
