Hy-Line pioneered genetic innovations that remain foundational today. Early breakthroughs included blood typing as a genetic marker to improve livability and predict productive crosses. Today, advanced molecular DNA techniques allow precise selection for traits such as egg production, feed efficiency, and disease resistance.
Field testing has always been a cornerstone of Hy-Line’s success. Hybrid crosses were—and still are—evaluated under diverse conditions, both in cages and on the floor, with meticulous records on egg production, livability, feed conversion, egg quality, and more. Today, Hy-Line’s global genetic evaluation program uses robust statistical models to analyze hundreds of millions of data points annually.
Egg quality was recognized early as a heritable trait. By the late 1940s, Hy-Line’s egg quality lab was breaking 200,000 eggs annually to measure Haugh units and assess shape, weight, and color. Today, Hy-Line’s laboratories test over one million eggs each year using state-of-the-art technology.
