Popis:	A matrix containing a hydrophobic binder, high-density non-toxic metal derivative (barium sulphate), a polymer (polyethyleneglycol) and the active ingredient, oxytetracycline constituted the components of the bolus. When 15, 17 or 20% oxytetracycline boluses were administered to fistulated Hereford and Angus heifers weighing about 364 kg and maintained on a dry-lot maintenance ration, a mean release of 92-172 mg oxytetracycline/bolus/day over a 60-70 day period was recorded.
