Heifer Heat Synchronization Made Simple(r)

Heifer Heat Synchronization Made Simple(r)

For those dairy farmers (and heifer raisers) who have a bit of trouble sticking to heat synchronization protocols in their heifers, George Heersche offers a simplified, three-step protocol that involves breeding on visual heat.

Heersche, an Extension dairy specialist with the University of Kentucky, says the protocol looks like this:

Day 0: Insert Eazi-Breed CIDR

Day 6 or 7: Inject prostaglandin F2 alpha

Day 7: Remove CIDR

Days 8-12: Watch for heat and inseminate the heifers detected in heat

“These heifers will come into heat 36 to 48 hours or later after the CIDR is removed. The expression of estrus and conception rates are normal,” says Heersche.

“This protocol synchronizes estrus but does not synchronize ovulation tight enough for timed insemination, so heat detection is required,” he says.

Breeding on standing heat is required because this program doesn’t synchronize ovulation tight enough.
