A horse is fed 19.1 pounds per day of hay (AF basis), and excretes 20.6 pounds per day of feces (as is) and 9.5 pounds per day of urine (wet). Lab analysis shows that the hay contains 91.2% DM and 59.1% neutral detergent fiber (NDF) on a DM basis, and the feces contains 30.4% DM and 52.9% NDF on a DM basis. What is the percent NDF digestibility of the hay?
