The heifer shortage and avian influenza reined in U.S. milk output in 2024, fostering lofty milk and dairy product prices in the second half of last year. But after nearly two years of low cull rates and sheer grit, the parlors are full, and so are the milk tanks. In the first 24 weeks of 2025, dairy cow slaughter was 7.7% behind the 2024 pace and 15.6% slower than historic average cull rates. Dairy producers added 122,000 cows over the past 11 months. From coast to coast, but especially in the center of the country, producers are looking to expand their facilities and add significantly more cows over the next 18 months.

The invisible hand is solving the heifer shortage. Years of decent profits and the promise of more prosperity on the horizon pushed producers to invest in new barns, forgo some beef calf income in favor of dairy calves, and cull as few cows as possible. Those efforts are adding up. USDA revised its estimate of the April milk cow herd. The agency now shows that dairy producers added 20,000 cows – rather than just 5,000 – that month, and they added another 5,000 in May. That puts the U.S. herd at 9.445 million milk cows, the highest head count since July 2021.

Strong exports have assuaged concerns about rising U.S. cheese and butterfat output. Even after a significant spring and early-summer rally, U.S. cheese and butter remain the cheapest in the world, putting a firm floor under these dairy commodities.

U.S. milk and dairy product output is growing quickly. But formidable exports are keeping a firm floor under the dairy markets. Even after sizable spring rallies, American cheese and butter are the cheapest in the world. Exports of those products are strong and likely to remain so. Daily average U.S. cheese exports surged to an all-time high in April, up 6.7% from already-lofty volumes in April 2024.

Even after the runup, U.S. cheese in the cheapest in the world, and exports are booming. The trade is searching for the price at which international buyers start to look elsewhere or simply make do with less. But prices may already be high enough to deter domestic demand. U.S. cheese consumption held steady in 2024, and it was down 0.8% year over year in the first quarter. With Cheddar north of $1.90, retailers will keep the cheese case stocked, but they probably won’t feature any promotions.

For several years the heifer shortage restrained growth in U.S. milk output. But the invisible hand has proved its might once again. Given enough time and economic incentive, industries can turn scarcity into abundance. Dairy producers have managed this feat by culling significantly fewer cows than they did in the past, reducing their need for replacement heifers.
