Preg Tech’s flagship project is in the development of a patented sensor (LuteiMate) for the detection of ovulation in dairy cows. This is an issue of major importance to farmers and one that is becoming increasingly difficult to manage. Preg Tech are developing a unique and promising way to approach this problem.

For an introduction to the problems facing farmers, please refer below. Provided is a snapshot of some of the current reproduction problems farmers must overcome to get their cows “in calf”. There is also data presented on the economics of the reproduction process and a high level market analysis.

  • Getting Cows In-Calf

Reproduction efficiency is the key: no calves, no milk!

The majority of western farmers use Artificial Insemination (A.I.), examples include:

~85% in AU, ~75% in NZ, ~90% in US and Netherlands

Right timing is essential otherwise pregnancy will not be achieved:

Approx. 67% of AU cows are currently being inseminated outside of 16hrs relative to ovulation with timing being a bit of a guessing game*
As such the average overall A.I. conception rate (CR) typically achieved is less than 35%, and similar in many dairy herds world wide
The direct and opportunity costs of this inefficiency are significantly affecting the bottom line of farmers

Farmers are already under huge financial pressure, and cannot afford these costs.

  • The economics of reproduction

Finding a cow truly on heat in Australia is worth ~A$200^, as calculated by Dairy Australia’s In-Calf Team, and includes:

Genetic gain from A. I. calves
Semen is not wasted on cows not on heat
Fewer cows to mop up at the end of A. I.
Fewer late calving or carry-over cows
Fewer cows culled because they are not in calf

“If you miss heats or submit cows not on heat you will have fewer A. I. calves and lose dollars.”^
This value of heat identification can be considered representative of all western countries, after accounting for local labour and equipment costs.
Preg Tech believe that accurate heat detection is the single most important thing that a farmer can do well

  • Reproduction Efficiencies in Dairy

Case study of the real problems: Consider an average 100 cow dairy farm

  • Around 50 cows are detected as ‘on heat’ using the current methods of oestrus detection (Senger, 1994)
  • With a per-round pregnancy rate of around 35%, ~18 cows are actually pregnant after first A.I. (i.e. 50cows x 0.35)
  • Assuming a few cows don’t hold the pregnancy, the actual number could be as low as 16 calving
  • The remaining cows wait another 18 – 25 days for re-insemination, and time taken to pregnancy test will also delay the process
  • A significant number of cows that are not pregnant after the first round of A.I. do not show signs of oestrous, and hence the detection rate will drop below 50% on the second round

Market Snapshot

ANZ and US farmers are influencers and industry leaders in best practice ~ 6.1 million dairy cows in ANZ, and ~ 16.6 million in Nth America

~ 150 million dairy cows globally
~A$55/cow per year directly spent on heat detection and A. I. in Australia

Current heat detection costs in Australia:~A$4/month for basic heat pads
up to ~ A$150/cow for more advanced methods such as activity sensors
A. I. semen costs in Australia:~A$27 on average per straw
Up to ~ A$75 per straw for sexed semen (excluding the cost of professional insemination services or farmers time)
Preg Tech estimate the market size to be ~A$270m/year total directly spent in ANZ and ~A$4.3b/year globally
