During one year selenium dynamics in the blood serum of 19 sheep was studied in relation to the degree of gravidity. Seasonal character of selenium dynamics with a positive reaction was demonstrated during the period of grazing, and a dependence of selenium serum concentration on the degree of gravidity was also proved; the highest mean value of selenium was recorded in ewes in the seventh month of gravidity (3.67 mumol.l-1). Delivery and onset of lactation reduced negatively selenium concentrations in the blood serum to the lowest selenium levels (2.15-1.89 mumol/l-1).
在一年时间里，研究了19只绵羊血清中硒的动态变化与妊娠程度的关系。结果表明，在放牧期间，硒的动态变化具有季节性且呈阳性反应，同时也证明了血清硒浓度与妊娠程度有关；妊娠第七个月的母羊血清硒平均含量最高（3.67微摩尔/升）。分娩和泌乳开始后，血清硒浓度呈负向降低，降至最低硒水平（2.15 - 1.89微摩尔/升）。
