INTERPRETATION OF RESULTS

A typical graph indicating the fluctuations in vaginal mucus resistance is presented. The optimal mating period is indicated. Often in practice, there are variations to this normal curve and the maximum peak reading between animals. Thus, this optimal graph may be adjusted to each breeder's own experience and that of the individual bitch. Some bitches may peak at 400 units where others peak at 600, 750 or over a 1000, but it is important to remember that it is the profile trace that is important and NOT the actual value of the readings.

We recommend the following interpretation of readings:

  • If the reading is between 100-200 units, there is no need to take daily measurements.
  • When readings rise above 200, daily measurements should be taken. Sometimes readings at this level may last a few days and then show a dynamic increase.
  • When readings begin to rise, it is advisable to take readings more frequently (such as 2, 3 or 4 times a day) to accurately determine the precise point of ovulation.

    Thus readings for example could be taken at breakfast, lunch, tea and suppertime. This is especially important in the case of a bitch that ovulates early, or only stands for a limited time to accept the dog. As shown on the graph, it is most important to record the maximum readings of resistance that are reached and shown on the LCD and the subsequent decrease in resistance values. Day one (and at the latest day two) AFTER the peak reading is the ideal time for mating.

    We encourage breeders to note the common "false peak" which occurs before the real one. It is easy to identify as it occurs at much lower resistance levels and is seen during the proestrous period at around days 3 to 5.
