Estrotect heat detection patches 50 ct Pink — scratch-off fuchsia markers, fast mount response

Estrotect 50 ct Pink are adhesive, scratch-off heat detection patches that reveal a colored marker when a cow is mounted, giving clear visual evidence of standing estrus.

Reproductive success depends on timely and accurate heat detection; Estrotect patches offer an affordable, low-tech way to record mounting activity across your herd. These fuchsia (pink) heat detectors use a scratch-off surface that rubs away under pressure, exposing a fluorescent color within seconds of effective mounting. Durable and easy to apply, they support artificial insemination and embryo-transfer programs by helping you identify candidates for breeding without constant individual observation.

How do Estrotect patches show a cow has been mounted?

The patches have a rub-away surface that removes when friction occurs from mounting, revealing a bright fuchsia color underneath. A single, forceful mount can expose color in as little as three seconds, creating an obvious visual cue for staff checking animals.

• Scratch-off top layer that rubs away under pressure
• Fluorescent fuchsia core that contrasts with cow hair
• Response time: color exposure possible in ~3 seconds of mounting

What’s the best way to apply and secure the patch for reliable results?

Warm the detector to about 100°F (38°C) before placing it to activate the adhesive and help it grip through cooler weather. Brush and then clean the hair along the backbone near the tailhead, place the patch perpendicular to the spine between the hip and tailhead, and press firmly to ensure full contact.

• Warm patches to body temperature for immediate adhesion
• Brush with the grain and wipe with a cleaning cloth to remove debris
• Position patches high on the tailhead to reduce tail-flick loss when flies are present

How long will a patch stay attached, and what conditions affect longevity?

Estrotect patches are built to remain on the animal for up to eight weeks under normal farm conditions. Longevity depends on factors such as weather, grooming, rubbing, and fly pressure; proper prep and placement increase the chances the detector stays put until it serves its purpose.

• Typical adhesion duration: up to 8 weeks
• High fly activity or heavy rubbing can shorten wear time
• Regular visual checks help catch early color exposure or premature loss

Can these patches be used with AI and embryo-transfer programs?

Yes—Estrotect patches are designed as a management aid for both artificial insemination and embryo-transfer recipients. They provide objective mounting evidence to help schedule insemination attempts or to identify prime recipients for embryo procedures.

• Works as an objective visual record for heat detection
• Supports timely insemination decisions for AI programs
• Helps monitor recipients in embryo-transfer workflows

Who is this for: Estrotect 50 ct Pink is intended for dairy and beef producers, herd managers, and veterinarians who need a cost-effective, low-maintenance tool to spot standing heat across multiple cows. It’s especially useful on operations that combine routine herd checks with timed breeding programs, where visual proof of mounting improves breeding timing and coordination.
