The PA Dept. of Agriculture Samuel E. Hayes, Jr. Livestock Evaluation Center (LEC) is a central testing station that will conduct controlled feeding and management tests, on either individuals or sire groups, within the four major species of meat animals (beef, swine, sheep, and meat goats) in order that genetic differences can be measured. 
The LEC shares direction from the Pennsylvania Department of Agriculture and The Pennsylvania State University.
There are four technical committees (one for each species) who meet to aid the director of the LEC in the operations and in the sales.
To provide a standard protocol to test bulls, rams and boars for economically important traits that can be used to enhance the commercial livestock industry of Pennsylvania.
The objectives of the center are:
  • Identify and promote the use of genetically superior sires
  • Measure growth rate, feed efficiency, carcass traits and/or carcass estimates under uniform conditions
  • Collect information not normally available on individual farms
  • Provide data that can be used with individual farm information that will provide the producer with a valuable selection tool
  • Demonstrate superior genetics in feed efficiency and amount and quality of meat produced
