This report delves into the U.S. genetic evaluation system for the dairy population, highlighting key statistics on milk yield. It focuses on 9.1 million dairy cows, with approximately 75% bred via artificial insemination (AI). Notably, 47% of these cows are milk recorded through Dairy Herd Information (DHI) programs. The majority belong to the Holstein breed (86%), with smaller percentages for crossbreeds and Jerseys. We analyze the typical herd size and average milk yield per cow, offering a comprehensive overview of the current state of the dairy industry.
