Ancestors and descendants are traceable. Upon the click of their id, have access to any relative's full information. See the animal's gender, if they were kept, and if any intervention was required at birth.


Calf information per cow is calculated and listed. It includes collected information and calculated items such as weaning weights relevant to the yearly average.

MooManager was designed and developed by Rachel Brownlee. She was working on the JHL cattle ranch in 2011 when she realized how valuable it would be to have a program manage AIing data for accuracy and speed. What started out as a simple data capturing application eventually became a management suite with detailed records and ability to calculate whether or not a cow should be considered for culling.

From 2011 to 2015 MooManager was a college project which she applied to every class. She won 8 awards and even a Nebraska State Legislative congratulation for the design and business plan for MooManager.

Since 2015 MooManager has become a fully functional and useful tool in the beta development stage. The JHL Ranch uses it extensively to manage all their cattle data. She has begun development for opening the application to other ranches.
