Good quality, dust free grass hay with a protein level of 10-12% is recommended for feeding alpacas. Alfalfa, on a day to day basis, is thought to be too rich for alpacas and too high in protein. Alfalfa will possibly cause the calcium level to go high, the phosphorus level to go too low, can cause urine scald, and can cause calcium deposits resulting in a block ureter. A steady diet of alfalfa also may be responsible for obesity in the llama/alpaca.
