Start your search by setting EPD ranges.

Seedstock producers on BullPEN have a unique handle (similar to an Instagram or Twitter handle, but for bulls) so users can search for bulls offered by a specific breeder. This allows breeders to build their social media brand consistently across platforms.

The app returns bulls that are offered at auction or private treaty that fit the parameters.

Preferred bulls can be saved to the “BullPEN”.
