High butterfat levels create hurdles for cheese makers
Demand for nutrient-rich dairy products like cheese, butter, and yogurt continues to grow in the United States and abroad. To meet this demand, U.S. dairy farmers have successfully increased milk butterfat levels over the past decade. However, a new report from CoBank’s Knowledge Exchange warns that butterfat growth has far outpaced protein, creating difficulties for cheesemakers.
Milk delivered to U.S. processing plants now contains higher butterfat percentages, but protein levels have not kept pace. Cheesemakers typically need a protein-to-fat ratio near 0.80 for ideal cheese quality. Today, that ratio has slipped to around 0.77, which can produce softer cheese and lower yields.
“U.S. dairy producers did an exceptional job increasing butterfat levels in milk to meet demand,” said Corey Geiger, lead dairy economist at CoBank. “For 10 years, the market couldn’t supply enough of it, and now there’s an oversupply – it’s almost too much of a good thing. Cheesemakers strive for a protein-to-fat ratio near 0.80. Anything significantly lower than that can reduce cheese quality and compromise production yields.” Other major dairy exporters like the European Union and New Zealand have kept their ratios steady, giving them a competitive advantage.
Historically, protein prices exceeded butterfat prices, encouraging balanced production. But in the past decade, butterfat prices often paid more, pushing farmers to focus on fat-rich milk through genetics and feeding strategies. Adjusting these practices, along with cheese yield pricing, could help farmers produce milk with a higher protein-to-fat ratio.
Despite these challenges, demand for milk components continues to rise worldwide. U.S. dairy processors are investing $10 billion in new plants through 2028, ensuring growth opportunities remain strong. Balancing butterfat and protein production will help U.S. cheesemakers stay efficient and competitive in both domestic and international markets.
