![]() The afimilk system installed in kibbutz Yavneh at the time of the study could indicate estrous in cows that had calved at least once, modern systems such as those described by Maatje et al. Deviations from each cow’s norm are marked as unrest, suspected estrous and possible ill health. The pedometers count steps per time unit, the numbers are transmitted to the information system and the hourly averages recorded. Cows within the afimilk system wear foot tags with pedometers that identify them in the milking stall. Unidentified estrous reduces the probability of timely insemination, increases the number of unintended and unproductive open days (days between calving) and may result in culling of high yielding cows.Ĭomputer-supported activity-measurements are used for identification of estrous. In these cases the cows are inspected by the veterinarian to determine estrous or the cause of its absence. Others may not display visible signs of heat – this is an anestrous condition. Success was verified after 28 days by testing for progesterone in the milk. These cows are examined, inseminated if found to be in heat. Most cows in Estrous can be detected by visible symptoms: unrest, mounting and vaginal discharge. Accurate detection and consequent insemination increase the probability of timely and successful conception. ![]()
