During the breeding period focus is very much on getting healthy cows pregnant quicker improving the 6 week in calf rate to enable more days in milk in early lactation, fewer replacements, fewer empties and improved herd and milk quality through selection.  The key focus areas during this period include:

“I now have 100% 6 week submission rate owing to better pre breeding management, I am getting better results with less effort” – Joe McCarthy, 200 health monitors


The single most important problem limiting high reproductive efficiency in dairy herds is poor estrus detection. A typical estrus detection rate of 50% highlights the challenge of estrus detection. Failure to detect estrus results in an estimated annual loss of over $300 million to the dairy industry in the US.


It is essential to understand the primary and secondary signs of heat in order to achieve accurate and efficient heat detection. Getting it right is a challenge that involves a significant amount of labour expense, effort and guesswork. Yet getting cows in calf quickly is at the core of every farmers business.

How can HerdInsights help?
  • HerdInsights, by using a multimetric analysis on each individual cows’ behaviours can accurately and efficiently detect cows in heat, taking the guess work out of it for the farmer with less time and hassle.

  • With a validated 96% heat detection rate, HerdInsights is very efficient in detecting silent heats

  • By detecting the onset of estrus conception rates are increasing by up to 20% on our existing customers farms

  • In addition to significantly improving your herds reproductive performance, HerdInsights will enable you to reduce straw usage and time spent observing cows.  Current recommendations are that for the period of AI use which is approximately 6 weeks traditional heat detection observation should take place for 3 periods of 30 mins each day


Dairy cows that have had a normal calving event and are healthy and well managed return to normal cyclicity within 15-20 days of calving. The first heat should be observed from approximately day 25 after calving and then normally occurs at 18-24 day intervals thereafter.


On average 50-80pc of cows within a herd fall into this category, with the balance of cows having delayed resumption of ovulation. A proportion of cows, given time, will repair any minor damage to the reproductive system after calving. Some, however, do need intervention to ensure that they resume cycling in time for the breeding season.


Early identification of non-cycling cows enables earlier intervention pre breeding maximising submission and pregnancy rates. Failure or late identification of these “problem” cows will result in an extended calving season, a shortened lactation number and increase the likelihood of eventually culling the cow.

How can HerdInsights help?
  • HerdInsights automatically generates a list of cows pre breeding that are not cycling relative to their calving date.

  • HerdInsights highlights the calving to first heat period


Since cattle should be inseminated so that viable sperm are at the fertilization site as the unfertilized egg arrives, it is important to estimate the time of ovulation for each cow that is to be inseminated.


Sperm have to be in the female reproductive tract for approximately six hours before they are capable of fertilising the egg. Although live sperm have been found in the female tract up to 48 hours after insemination, sperm viability usually is estimated to be 18 to 24 hours. Improper semen handling or poor insemination technique can dramatically reduce the number of sperm cells available for fertilisation and thus can lower the conception rate.

How can HerdInsights help?
  • When a cow is in heat HerdInsights will send an alerts directly to the farmers and/or inseminators phone. Included in the alert will be critical information that will increase the likelihood of a conception.

  • HerdInsights will indicate when the onset of estrus commenced maximising your chances of success.

  • Other information such as DIM, previous estrus duration, time between estrus events and whether or not previously served will be displayed in the alert and will greatly improve pregnancy rates on farm.
