The Beef Cow Herd Efficiency Calculator was developed to assist Tennessee cow-calf producers in improving cow herd genetics. The calculator will assist producers in identifying the higher-performing and lower-performing cows in the herd. It can also serve as a tool for selecting replacement heifers.

Note Regarding Security Settings: The decision-aid file contains macros (examples: buttons for printing and moving from the intro page to the calculator) which are required for the calculator to function properly. Security settings for Microsoft Office or Excel may give you warnings when you open the file regarding the safety of enabling the macros. This will especially be true if your security settings are set to high or very high. The macros in the file must be enabled for the calculator to function properly.
