US milk production continues expanding in June amid higher cow numbers

US milk production continued to expand in June, supported primarily by ongoing dairy herd growth while milk yields remained broadly stable. Production gains were concentrated in a handful of fast-growing states, reinforcing the regional shift in milk supply despite mixed developments in farmgate prices. Although recent heat waves could challenge output in the coming months, the strong first-half performance has kept US milk production on a solid growth trajectory heading into the second half of 2026.
