Desoxyribonucleic Acid (or DNA) is the molecule that carries the genetic instructions used in biological functions, of all living organisms. A genome is a complete set of genetic material in an organism, serving as an instruction manual for life. Every living thing, from humans to chickens, has one, and it contains all the information needed for development and overall function. Scientists have been studying DNA for over a century, but the ability to read the entire genetic code of an organism—called genome sequencing—only became possible in the 1970s. Since then, genomics research has advanced rapidly, helping researchers in a wide range of fields, from medicine to agriculture.

By studying a chicken’s DNA, we can identify qualities that contribute to good health and productivity, such as strong legs, reproductive fitness and healthy growth. These insights allow us to make precise, balanced selections in our breeding programs—building on generations of careful breeding to enhance bird welfare and sustainability.

Genomics has improved the way we measure hard-to-see traits, giving us a more complete picture of each bird’s potential. For example, it has helped enhance selection for feed efficiency, reproductive traits, better immune systems and growth. It also helps make breeding predictions more accurate, especially for traits that apply to only one sex, like selecting males based on egg production potential. By combining this data with traditional hands-on selection, we can make steady progress in breeding birds that are not only productive but also robust.

This scientific breakthrough has reshaped poultry breeding, helping the industry keep pace with an ever-growing global demand for high-quality, sustainable poultry. By making informed breeding choices, we’re not only improving animal health and welfare but also ensuring sustainable poultry meat production.
