Delbeke, F.T. and Debackere, hi., 1991. Urinary excretion of theobromine in horses given contaminated pelleted food. Vewrimny Research Communications, 15 (2), 107-116 A high pressure liquid chromatographic (HPLC) method for measuring the theobromine content in cocoa husks, pelleted food and horse urine is described. Starting with 2 ml of urine, concentrations of SO0 rig/ml could easily be detected. When feed containing 38.4 mg of theobromine was given twice daily to horses for 2% days, two days were needed after the last intake before the theobromine concentrations fell below the threshold value of 2 &ml. The time at which the peak excretion rate occurred varied from 2 to 12 h after the last administration, while the excretion rate seemed to be dependent on the urinary flow. Theobromine could not be detected in plasma after administration in this way.
