[Comparison of different methods of calculating the retention time of feed residues in the total digestive tract of the dairy cow].
Two-compartment time-independent model (2C) and one-compartment time-dependent model (1C) of degree 2 for concentrates and 3 for forages provided estimates of total mean retention time (MRT) in the digestive tract which were similar to direct calculations but more variable. Model 1C was found superior in fitting the data.
