The human digestive system converts food into nutrients that the body needs. Saliva keeps the rumen pH between 6.2 and 6.8 for best digestion of forage and feedstuffs. Four saliva samples are taken at specific times and then shipped to a laboratory for analysis. Saliva moistens dry food and contains salivary amylase, a digestive enzyme that begins the digestion of carbohydrates. Mucus serves as a protective barrier and lubricant inside of the GI tract.
