The USDA estimates are based on quarterly surveys (January, April, July and October) of dairy farmers in 24 major dairy states, as well as an annual survey (February) in all states. The prices reflect those paid or received for cows that have had at least one calf and are sold for replacement purposes, not as cull cows. The report does not summarize auction market prices.
When overlayed on USDA Milk Production reports, changes in average replacement prices were weakly correlated with trends in cow numbers. The major states saw dairy cow numbers drop by about 22,000 between August and September (the latest estimates available), with largest declines in New Mexico and Washington. As of September, U.S. cow numbers were down 85,000 head since peaking in May 2021 and were the lowest since December 2020.
Compared to the previous quarter, average replacement cow prices were down in 15 of 24 major dairy states tracked by the USDA (Table 1). Decreases of about $100 per head were reported for New Mexico and Oregon. Countering that, average prices were modestly higher in seven states, led by Texas and Utah, up $50 per head.
