Use of the optical refractometer in performing a rapid assessment of the immunoglobulin content of ovine colostrum under farm conditions was investigated. Refractometer readings were compared with total protein levels and with gamma-globulin levels, determined by the ZSTT, to assess the validity of the technique. In both cases correlation coefficients were high (0.98 and 0.79 respectively). Refractometry was shown to be a valid substitute for the ZSTT in studies on colostrum gamma-globulin levels.
研究了在农场条件下使用光学折射仪快速评估绵羊初乳免疫球蛋白含量的情况。将折射仪读数与通过ZSTT测定的总蛋白水平和γ-球蛋白水平进行比较，以评估该技术的有效性。在这两种情况下，相关系数都很高（分别为0.98和0.79）。在初乳γ-球蛋白水平的研究中，折射测定法被证明是ZSTT的有效替代方法。
