What is P4Gold?

A real-time fertility tool

Accurate and well-timed heat detection is hard. Made harder by the 30% of cows that show no reliable signs or behaviours.

Now, a simple in-milk test with P4Gold will confirm whether or not your cow is in heat.  And all it takes is a milk sample from your cow and 20 minutes to run a simple test in the parlour.

P4Gold gives you clear and accurate information to help you manage the fertility of your herd

Used on its own or alongside other heat detection devices, P4Gold will:

  • Prevent mistimed insemination
  • Prevent insemination of an already pregnant cow
  • Prevent incorrect calving dates and mistimed dry periods
  • Detect silent heats
  • Improve PD percentages
  • Help you investigate poor fertility
  • Help you investigate non-cycling cows
  • Help you diagnose problems such as persistent corpus luteum
  • Work alongside other heat detection methods to remove false positives
  • Detect non-pregnant cows 19-23 days post insemination

Please note P4Gold is not a pregnancy or PAG test and is not intended for use on its own as a diagnostic tool.

Why a milk test?

A healthy cow has a 21-day cycle involving six different hormones. One of these hormones is progesterone. Your cow’s progesterone levels show in its milk. So testing the milk will tell you if your cow is cycling and when she’s ready for AI.

The main external sign that a cow is cycling is standing heat. However, it’s only visible for short periods throughout the day, making it easy to miss. And some cows stand to be mounted when they’re not in heat, so it’s not always reliable.

Another sign of oestrus is bulling. But false bulling is common, so again, this is not reliable. And some cows go through their entire cycle and display no outward signs of oestrus, even though they are perfectly healthy and fertile.

This is why tracking progesterone is the most reliable way to confirm heat. And so improve the fertility and productivity of your herd.
