Whether you’re using AI, embryo transplant or natural breeding purposes, knowing when your cows are in heat is important. AHD is the exclusive distributor of Bovine Heat Tags, an industry leading rub-off heat detection system, in New Zealand.  Bovine Heat Tags are an excellent aid for dairy and beef producers in detecting cows in mounting-heat.  Apply the detectors to your cows prior to coming into heat, when synchronising estrus cycles or after breeding and embryo transplant to check for return heat.

A.I. Tags

A.I. Tags are the only true Rub-Off tag in the world.  A.I. Tags require pressure from mounting activity to allow the surface of the tags to rub-off and display the signal colour underneath. THERE ARE NO FALSE POSITIVES WITH AHD A.I. Tags.

Available in 4 sleeves of 50 tags = 200 tags. Please email sales@ahdltd.co.nz to order.
