U.S. Legacy as Genetic Leaders

The United States is respected as a premiere model for dairy management and genetic improvement. Producers worldwide use U.S. genetics to develop healthier, more productive dairy herds.

Continuous Improvement

Through collaboration and innovation, U.S. dairy genetics evolve continuously to use the latest scientific and technological tools and fit changing dairy production environments and markets.

Genetics to Fit any Production System

With a large geography, the U.S. is home to diverse cultures and climates. This results in diverse dairy management styles and a broad genetic portfolio developed to thrive in many systems.

U.S. as Largest Semen Exporter

With experience in exports back to 1960, the U.S. currently exports over 30 million units of U.S. produced frozen bovine semen to producers in 120 countries worldwide each year.

While the Holstein is the predominant dairy breed, the U.S. dairy population also includes thousands of Jersey, Ayrshire, Brown Swiss, Guernsey, and Milking Shorthorn cows.

Cooperation at the Core

The foundation for genetic excellence began a century ago with the start of U.S. milk recording. Today cooperation continues to be central to the U.S. system. Farmers and many organizations work together to accurately record and collect data, research cutting-edge innovation, and aggregate quality data to calculate genetic evaluations that benefit dairy producers. A unique coding system allows data to be tracked from farm to evaluation.

U.S. Genetic Impact Globally

Frozen semen from U.S. sires for artificial insemination has been exported around the world since the 1960s.

Dairy Cross Reference Database

The dairy cross reference database includes 97,000 AI sires representing 28 countries and 18 breeds.

These A.I. bulls receive official U.S. genetic values 3 times a year. Alongside semen collected in the USA, A.I. bulls around the world are selected and marketed on U.S. genetic values.
