Diurnal variation in fecal concentrations of acid-detergent insoluble ash and alkaline-peroxide lignin from cattle fed bermudagrass hays of varying nutrient content

Table 3 Comparison of measured in vivo fecal output (FO, g/d) and dry matter (DM) digestibility (DMD, g/kg DM) with estimates determined using acid-detergent insoluble ash (ADIA), and alkaline-peroxide lignin (APL) using samples from different sampling times and their combinations^a

^a1, sampled at 06:00 h; 2, sampled at 12:00 h; 3, sampled at 18:00 h, 4, sampled at 24:00 h. The two, three, and four-digit numbers represent combinations of the different sampling times
^bTC, total collection
^cSEM, standard error of the means
^dD, diet; T, time effect; D × T, diet by time interaction
^eD, diet consisted of low (L) CP hay (CP = 79 g/kg DM); medium low (ML) CP hay (CP = 111 g/kg DM); medium high (MH) CP hay (CP = 131 g/kg DM); and high (H) CP hay (CP = 164 g/kg DM)
