Various copper compounds (CuSO4, Cu-glycinate, Cu-lactate, Cu-citrate) were applied subcutaneously, intramuscularly, and intravenously to 17 barrows, doses being up to 50 mg Cu, while doses between 0.5 g and 1.0 g CuSO4 were orally administered. Curves of copper levels in the serum then were checked at different times. In response to intravenous application, copper levels reached maximum values as early as after two minutes and dropped to the normal about 90 minutes from application. Subcutaneous and intramuscular applications had but little effect on serum copper levels, while oral administration actually had none at all.
将各种铜化合物（硫酸铜、甘氨酸铜、乳酸铜、柠檬酸铜）以皮下、肌肉内和静脉内的方式施用于17头公猪，剂量高达50毫克铜，同时口服0.5克至1.0克硫酸铜。然后在不同时间检查血清中铜水平的曲线。静脉注射后，铜水平早在两分钟后就达到最大值，并在注射后约90分钟降至正常水平。皮下和肌肉内注射对血清铜水平影响甚微，而口服实际上毫无影响。
