Same as for mature house rabbits especially when considering their potentially long hair length. Due to their increased protein requirements, the richer protein of a legume hay will not be harmful to angoras, however, the extra calcium may be a concern.

Protein Functions Protein is essential to make a bunny.
Proteins help make bone and muscle and fur, they also are responsible for turning food into energy.
Proteins are important for the proper functioning of the cecal bacteria Types Proteins are composed of amino acids. There are 20 common amino acids, some of which are synthesized by rabbits and others that are not. Those which bunnies cannot make are called essential amino acids. The diet provides a significant portion of these amino acids. However, the cecal bacteria can make the essential amino acids and the cecal pellets are also an excellent source.
