Alfalfa hay offers a range of benefits, especially for specific groups of rabbits, such as young, growing rabbits, pregnant or nursing does, and rabbits in need of additional nutrition. Here are the primary benefits of Alfalfa hay:

1. High Protein Content: Alfalfa hay is rich in protein, which is essential for the growth and development of young rabbits. It supports muscle development and overall growth in juvenile rabbits.
2. High Calcium Content: The high calcium content in Alfalfa hay is beneficial for young, growing rabbits, pregnant or nursing does, and rabbits with certain medical conditions that require extra calcium.
3. Energy-Rich: Alfalfa hay has a higher caloric content compared to other hays, providing the necessary energy for young, active rabbits and those with higher metabolic needs.
4. Palatability: Rabbits generally find Alfalfa hay very palatable due to its sweeter taste, making it an excellent choice to encourage eating, especially in rabbits that are underweight or have a reduced appetite.
5. Nutrient-Dense: In addition to protein and calcium, Alfalfa hay is rich in vitamins and minerals, including vitamin A, vitamin D, and various B vitamins, which support overall health and well-being.
6. Digestive Support for Young Rabbits: The high fiber content, though less than that of Timothy hay, still supports healthy digestion in young rabbits and helps establish good eating habits.

It’s important to note that while Alfalfa hay has these benefits, it should be fed in moderation to adult rabbits due to its high calcium and protein content. Excessive calcium intake in adult rabbits can lead to urinary tract issues, such as bladder stones or sludge. Therefore, Alfalfa hay is primarily recommended for young, growing rabbits and other rabbits with specific nutritional needs.
