[Thiocyanate blood levels in roe deer, red deer, fallow deer and wild boar]

The following serum levels of thiocyanate (SCN-) were found in game: roe 6.6 +/- 4 mg/l, red deer 5.5 +/- 3.2 mg/l, fallow-deer 5.1 +/- 2.8 mg/l, and wild boar 4.8 +/- 4.5 mg/l (variation 0.6-32.6 mg SCN-/l). These levels are distinctly higher than in domestic animals under stall-feeding with exception of mast calves which were fed milk-substitutes. The SCN- serum level of calves, sheep and horses reach at pasturing nearly the level of game. The higher SCN- serum level of cloven-hoof game resp. by pasturing of domestic animals is caused by higher alimentary SCN- intake.
