Fig. 6. Average pseudo-partitioning coefficient as a function of time for TC, CTC, SMT, and MNS. Time had no impact on the pseudo-partitioning coefficients for STZ, ERY, and TYL, and therefore they are not shown. TC = tetracycline, CTC = chlortetracycline, SMT = sulfamethazine, MNS = monensin, STZ = sulfathiazole, ERY = erythromycin, and TYL = tylosin.
