More About BullPEN

BullPEN is a tool for searching bulls that are for sale via auction or private treaty.

Search bulls by breeder, EPD ranges, Sire/Bull Name, and Location.

The BullPEN app currently supports 5 breeds:
Angus, Hereford, Red Angus, Simmental/SimAngus™, and Charolais.

A search for bulls on the app starts by setting EPD ranges.

Using the “breeder handle” feature (similar to an Instagram or Twitter handle, but for bulls), 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”.

Because Genotype Isn’t Everything…

Phenotype is important along with solid relationships! That is why BullPEN offers a variety of ways for breeders to connect:

Through BullPEN
users can instantly:

-Look up sale location in maps
-Link video catalog
-Call the breeder
-Email the breeder
-Visit the breeder website
-Sign up for online bidding on the auction website
-Look up the bull on the breed association website
-Select the breeder handle to see all bulls of the selected breed by that breeder

Example of a Bull Information screen:

BullPEN is not designed to complete the sale transactions of bulls but only as a tool to point a buyer to the bulls they are looking for.
