Generic Estrotect Heat Detector sticker Red/Orange — 10-pack breeding indicator, fluorescent mounting reveal

Estrotect Heat Detectors are self-adhesive breeding indicators that reveal mounting activity with fluorescent color to help pinpoint peak estrus timing for cattle.

Designed for beef and dairy herds, the Estrotect Heat Detector (Red/Orange) uses Breeding Bullseye Technology: a single sticker applied between the hip and tail head changes visibly as animals are mounted, offering a straightforward, low-cost method to identify when a cow or heifer is at maximum opportunity for conception. Available in multiple pack sizes from 5 to 50, these stickers are widely used on commercial farms and research trials for reliable estrus detection without continuous observation.

How do Estrotect Heat Detectors show when an animal is in heat?

The sticker is applied halfway between the hip and tail head, perpendicular to the spine; mounting action causes the outer coating to rub away, revealing the contrasting fluorescent color beneath. The more mountings that occur, the more visible the indicator becomes, creating an easy visual record of recent activity.

• Apply once per breeding cycle — stays in place during normal herd movement.
• Highly visible red/orange fluorescent color appears with mounting rubs.
• Simple read: more exposed color = more mounting events.

How accurate are these stickers compared with other detection methods?

Independent trials and broad field use show Estrotect performs reliably alongside traditional detection methods and has been shown in some studies to be comparable to a bull for identifying standing heat. They serve as a practical complement to visual observation, activity monitors, or tail chalk by providing a physical, time-stamped indicator of mounting intensity.

• Proven in field trials and on commercial operations worldwide.
• Useful as a confirmatory tool for AI timing and pregnancy checks.
• Reduces need for continuous observation during peak activity periods.

What is the correct way to apply and read an Estrotect sticker?

Place the sticker halfway between the hip and the tail head, aligning it perpendicular to the spine so mounting contact occurs naturally across the sticker face. Inspect regularly: small color spots indicate some mounting activity, while large, bright fluorescent areas indicate stronger or repeated mountings.

• Clean and dry the application spot for best adhesion.
• Apply once per cycle; replace after confirmed breeding or at next cycle.
• Use alongside heat detection routines to improve timing decisions.

Who is this for: Estrotect Heat Detectors suit dairy farmers, beef producers, and herd managers who want a low-maintenance, visible way to track estrus activity without continuous monitoring or expensive equipment. They are helpful for operations of all sizes—especially those using timed AI protocols, managers needing confirmation of standing heat, or teams wanting a quick physical record of mounting intensity to guide breeding decisions.

Product notes: Estrotect Heat Detectors are self-adhesive, require a single application per breeding cycle, and come in pack sizes ranging from 5 to 50 stickers to suit small herds and large operations. Follow on-farm protocols and veterinary guidance for optimal breeding program results.
