** AWARDS ISSUED PRIOR TO JANUARY 20, 2025, WERE FUNDED UNDER PREVIOUS ADMINISTRATIONS AND MAY NOT REFLECT THE PRIORITIES AND POLICIES OF THE CURRENT ADMINISTRATION.** DAIRY YOUNGSTOCK, CALVES AND HEIFERS, ARE THE FUTURE OF THE MILKING HERD AND REPRESENT A SUBSTANTIAL ON-FARM INVESTMENT. IT IS WELL ESTABLISHED THAT CONDITIONS DURING THE REARING PERIOD HAVE LIFETIME CONSEQUENCES. FURTHER, DAIRY ANIMALS CONTRIBUTE TO GREENHOUSE GAS EMISSIONS AND COMPETE FOR LAND AND FEED RESOURCES. THEREFORE, THE LONG-TERM GOAL OF THIS PROJECT IS TO IMPROVE THE SUSTAINABILITY OF THE US DAIRY INDUSTRY THROUGH AN IMPROVED UNDERSTANDING OF THE GENETICS UNDERLYING FEED UTILIZATION. TO ACCOMPLISH THIS LONG-TERM GOAL, WE WILL EVALUATE THE GENETIC INFLUENCES OF DAIRY HEIFER FEED UTILIZATION AND GROWTH PARAMETERS, COMPARE METHANE PRODUCTION AND ENERGY EFFICIENCY BETWEEN CALVES, AND ESTABLISH THE ECONOMIC BENEFITS OF IMPROVED FEED EFFICIENCY. WE EXPECT TO SHOW THAT THERE IS A MEASURABLE GENETIC COMPONENT UNDERLYING FEED UTILIZATION AND METHANE PRODUCTION IN GROWING DAIRY YOUNGSTOCK ACROSS DIFFERENT AGES OF THE GROWING PHASE. FURTHER, WE EXPECT THAT ANIMALS HAVING GREATER FEED UTILIZATION EFFICIENCY WILL ALSO HAVE REDUCED COSTS TO PRODUCERS. THIS WORK WILL CONTRIBUTE TO IMPROVED FARM PROFITABILITY AND IMPROVED ENVIRONMENTAL SUSTAINABILITY OF DAIRY YOUNGSTOCK.
