Table 2 Dry matter intake (DMI), fecal output (FO), and DM digestibility (DMD) of bermudagrass hay with differing concentrations of crude protein (CP) fed to cattle based on total collection (n = 6)

From: Comparison of acid-detergent lignin, alkaline-peroxide lignin, and acid-detergent insoluble ash as internal markers for predicting fecal output and digestibility by cattle offered bermudagrass hays of varying nutrient composition
