The dicumarol concentration in 272 cured sweet clover samples from 4 counties in North Dakota was determined. Dicumarol concentrations ranged from 0 to 164.7 mg/kg of sweet clover, with 64.6% of the 272 samples containing less than 10 mg/kg. Round bales were significantly (P less than 0.05) higher in dicumarol concentration (mean of 22.9 +/- 3.10 mg/kg) than were stacks or silage (means of 1.8 +/- -6.3 mg/kg and 0.6 +/- 2.1 mg/kg, respectively). The outer section of core samples taken from round bales contained significantly (P less than 0.0021) higher concentrations of dicumarol than did the inner section of the core, with means of 30.8 mg/kg and 16.6 mg/kg, respectively. A significant (P less than 0.0001) correlation existed between crude protein and dicumarol values (r = 0.44).
测定了来自北达科他州4个县的272份治愈的草木樨样本中的双香豆醇浓度。双香豆醇浓度在0至164.7毫克/千克草木樨之间，272份样本中有64.6%的双香豆醇含量低于10毫克/千克。圆捆的双香豆醇浓度（平均为22.9±3.10毫克/千克）显著（P小于0.05）高于堆垛或青贮饲料（分别为1.8± -6.3毫克/千克和0.6±2.1毫克/千克）。从圆捆中取出的芯样外部双香豆醇浓度显著（P小于0.0021）高于芯样内部，平均值分别为30.8毫克/千克和16.6毫克/千克。粗蛋白和双香豆醇值之间存在显著（P小于0.0001）相关性（r = 0.44）。
