Alpacas will chew their food in a figure eight motion, swallow the food, and then pass it into one of the stomach's chambers. The first and second chambers are where the fermentation process begins digestion. The alpaca will further absorb nutrients and water in the first part of the third chamber. The end of the third chamber is where the stomach secretes acids to digest food, and is the likely place where an alpaca will have ulcers, if stressed. The alpaca digestive system is very sensitive and must be kept healthy and balanced.[1
