** AWARDS ISSUED PRIOR TO JANUARY 20, 2025, WERE FUNDED UNDER PREVIOUS ADMINISTRATIONS AND MAY NOT REFLECT THE PRIORITIES AND POLICIES OF THE CURRENT ADMINISTRATION.** ONE OF THE MAJOR DEVELOPMENTS IN ANIMAL BREEDING AND GENETICS IN THE LAST DECADE IS USING GENOMIC INFORMATION (E.G., DNA) TO IDENTIFY AND SELECT THE BEST ANIMALS IN A PROCESS CALLED GENOMIC SELECTION (GS). GENOMIC SELECTION INCREASES THE ACCURACY OF SELECTION AND DECREASES GENERATION INTERVAL, WHICH RESULTS IN INCREASED GENETIC PROGRESS FOR TRAITS THAT ARE ECONOMICALLY IMPORTANT IN THE US. BECAUSE OF THE FAST TURNOVER, GS CAN HELP IMPROVE TRAITS OF INTEREST (E.G., PRODUCTION) FASTER BUT MAY ALSO HELP DETERIORATE LESS FAVORED BUT IMPORTANT TRAITS (E.G., FERTILITY AND FITNESS). INFORMAL REPORTS ABOUT THE FAST DETERIORATION OF TRAITS STARTED EMERGING RECENTLY FROM THE INDUSTRY AND PRODUCERS. HOWEVER, CURRENTLY, THERE ARE NO METHODS TO INVESTIGATE WHETHER GS IS RESPONSIBLE FOR THIS DETERIORATION. WE WILL EXTEND CURRENT AND DEVELOP NEW METHODS TO BE ABLE TO INVESTIGATE HOW HIGHLY AND LESS FAVORED TRAITS BEHAVE IN THE PRESENCE OF GS. THEN, WE WILL TEST THESE METHODS IN CATTLE, PIG, AND CHICKEN POPULATIONS UNDER GS. WITH THAT, WE WILL BE ABLE TO IDENTIFY WHICH TRAITS ARE MORE LIKELY TO DETERIORATE UNDER GS AND DESIGN MITIGATION PLANS. THIS WILL HELP PRODUCERS TO TAKE ACTION BEFORE IMPORTANT TRAITS ARE AFFECTED.
