After addressing the typical concerns (cation-complexing,
water concentrations, and differences among
the groups) and new problems noted (water color
change and indirect linear exposure-concentration),
tetracycline water medication concentrations as dosed
were found to be consistent with tetracycline feed additive
concentrations. In one feed additive study, Kniffen
et al. (1989) dosed 4 gilts with 0.55 g of tetracycline per
kilogram of BW.
