P4 HeatRead™ Milk Progesterone Test - 25 Kit

Be sure before you breed. 

P4HeatRead™  brings lab-level accuracy on farm, showing you what’s happening hormonally, not just behaviourally. Results in 10 minutes to help you manage your herd’s fertility. 

Use it to

• Confirm a cow is in heat and hormonally ready for AI

• Detect non-pregnant cows early, from 19 days post AI

• Identify non-cycling cows 

• Catch silent heats and double check false alerts

P4HeatRead™ can be used as a standalone or alongside other heat detection devices. It’s been validated across multiple milk types, including high-fat Jersey milk, and doesn’t cross-react with other reproductive hormones.
