Estrotect estrus detection patches Pink 50 ct — adhesive, fluorescent pressure‑sensitive monitors

Reproductive success in dairy and cow/calf operations depends on timely, visible evidence of standing heat. Estrotect 50 ct Pink patches are a practical, low-cost tool designed to flag mounting activity so producers can identify cows likely in estrus. Their vibrant fuchsia color and pressure-sensitive surface make them easy to spot in pens or pastures, and a single mounting can expose color in seconds.

How do these patches show that a cow has been mounted?

Each Estrotect patch has a pressure-sensitive overcoat covering a fluorescent layer. When another animal mounts and rubs that surface, the top coating abrades and reveals the bright fuchsia underneath—providing clear visual proof of physical activity.

• Mounting pressure removes the outer coating.
• Fluorescent color becomes visible within seconds of a single mount.
• Easy-to-see contrast against common coat colors and in group settings.

What is the best way to apply and keep these detectors working?

Proper preparation and placement are important for reliable adhesion and longest wear. Warm the patches before applying, clean and brush the coat where they’ll be placed, and position them between the hip and tail head perpendicular to the spine for optimal contact and protection from tail flicking.

• Warm patches to roughly 100°F (38°C) to activate the adhesive—hold near your body or use a warm container.
• Brush and clean the hair across the backbone to remove dirt, loose hair, and debris.
• Place high on the rump near the tail head and evenly spaced for best detection and to avoid tail damage.

How long will a single patch last, and how quickly does it respond?

Estrotect detectors are formulated to remain attached for extended monitoring periods while responding rapidly to mounting activity. A properly applied patch can stay effective for several weeks and often reveals a single mount in only a few seconds.

• Color can be exposed in as little as three seconds from one mounting event.
• When applied correctly, patches remain functional for up to eight weeks.
• Economical for herd-wide monitoring during breeding cycles.

Can these patches be used with A.I. programs or embryo transfer monitoring?

Yes—Estrotect patches are a straightforward management aid for timed insemination and embryo transfer protocols. They supply visual evidence of mounting that helps schedule insemination or follow-up checks without complex equipment.

• Useful for detecting standing heat before A.I. or in embryo recipient monitoring.
• Bright fuchsia color offers high visibility in varied herd environments.
• Low-cost option to support reproductive program recordkeeping.

Who is this for? Estrotect 50 ct Pink is intended for dairy farmers, beef producers, and herd managers who need a proven, low-tech method to detect mounting and identify cows in estrus. It's especially helpful for operations using artificial insemination or embryo transfer that require clear, visual confirmation of standing heat without relying on electronic systems.

Key features:

• Simple adhesive patches that reveal color when rubbed off.
• Visible fuchsia color exposed by mounting activity.
• Fast response—can show mounting in about three seconds.
• Durable adhesion for monitoring periods up to eight weeks.
