BREED WITH CONFIDENCE Estrotect Breeding Indicators are proven to help beef and dairy cattle breeders accurately detect estrus intensity, increase confirmed pregnancy rates, inform breeding decisions and improve cattle breeding programs. The Estrotect Breeding Indicator features Breeding Bullseye Technology that indicates when cows are ready to breed, helps confirm pregnancies and provides pinpoint timing for AI protocols. ESTROTECT Heat Detectors are self-adhesive heat detection tools proven to help dairy farmers and beef ranchers determine when their animals are at the maximum opportunity for pregnancy. ESTROTECT Heat Detectors are applied halfway between the hip and the tail head spaced perpendicular to the cow’s spine. As more mountings occur, more of the highly visible fluorescent coloring will appear. More rubs = More Mountings = Maximum Opportunity for Pregnancy. With over a decade on the marketplace and more than 25 million units used worldwide, ESTROTECT Heat Detectors are guaranteed to have a positive impact on your breeding program*. In recent trials, ESTROTECT Heat Detectors showed to perform As Good As A Bull in determining standing heat (SDSU, 2005). Available in packs of 5, 10, 15, 20, 25, 30, 35, 40, 45, & 50 stickers.
