Table 1 Chemical composition (g/kg dry matter, DM) of bermudagrass hays fed during an in vivo experiment for estimating marker recovery based on different crude protein (CP) levels (n = 3)

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
