Poultry Science Department, University of Wisconsin, Cackelator: American Poultry Historical Society Papers Introduction

The Poultry Science Department, University of Wisconsin, donated an electronic box titled CACKALATOR, Linthicum, Maryland, 21090. This electronic device was used by Ag-Way Co-op representatives as an early on-the-farm "Computer" to formulate feed mixtures based on flock production factors such as body weight, egg weight, percent production, etc.

An array of 21 switches, dials and knobs are used to formulate the crude protein, metabolizable energy, methionine in protein, etc. in the finished feed.

The brief-case size device was carried to the farm and used by the feed representative and the flock-owner to make nutritional determinations to provide the highest net income for the poultryman.
