As more Americans chose to eat more cheese, farmers look for ways to increase milk fat content

What's better than cheese? More cheese. That's what many Americans are telling the U.S. dairy industry. But heightened demand for rich-tasting young gouda and spunky blue cheese comes with a catch -- dairy farmers need their cows to produce fattier milk, reports Kirk Maltais of The Wall Street Journal. "Just five years ago, dairy farmer Melvin Medeiros said his herd consisted entirely of Holsteins, which are the black-and-white spotted cows. . . . Now about 70% are brown Jersey cows, which are smaller but produce a fattier milk."

In dairy-producing states such as Wisconsin and Vermont, loving cheese is threaded throughout the culture, but the rest of the country is catching on. "Cheese consumption is at an all-time high, with Americans eating an average of 42 pounds a year in 2022, according to the most recent data available from the Department of Agriculture," Maltais writes. "That is up 17% over the previous decade." Although butter sales declined in 2022, consumption is still up 9% compared to a decade ago. 


Beyond switching cow breeds, what else can farmers do to "squeeze" fattier milk from their herd? It comes down to keeping cows comfortable and providing a richer diet. "Cross-ventilated barns ensure animals don't get too hot," Maltais explains. "Keeping cows cool helps them get fatter — and produce fattier milk. Medeiros adds oilseeds like cottonseed and canola to their feed."


Michael Hutjens, professor emeritus of animal sciences with the University of Illinois, told Maltais, "We're seeing a lot more money invested in fans and sprinklers." Maltais reports: "Hutjens said breeding and genetics could help push up fat levels in milk even more."
