Studies were conducted on how to use under the conditions of industrialised production in the GDR an electrometric method proposed by Soviet scientists to determine oestrus and ovulation date in oestric-synchronised heifers and cows. "Oestrometer-2", an instrument developed in the USSR, was used for 4,818 measurements of electric resistance in 700 oestric-synchronised heifers and 39 oestric-synchronised cows. The typical course of the resistence curve was confirmed by the results. Individual data variation together with unsatisfactory data reliability of the instrument, when applied to measurement at vaginovestibular mucosa, were likely to suggest that the method could not be used with good effect for high-accuracy determination of the ovulation date and therefore, was not useful in helping to save semen pellets after oestric synchronisation.
针对如何在民主德国工业化生产条件下运用苏联科学家提出的一种测定发情同步化的小母牛和母牛发情期及排卵日期的电测法开展了研究。使用了苏联研发的“发情测定仪 -2”对700头发情同步化小母牛和39头发情同步化母牛进行了4818次电阻测量。结果证实了电阻曲线的典型变化过程。当应用于阴道前庭黏膜测量时，个体数据变化以及该仪器数据可靠性不令人满意，这可能表明该方法无法有效地用于高精度确定排卵日期，因此，在发情同步化后帮助节省精液颗粒方面并无用处。
