When thinking about sustainability, we often consider how the industry impacts the environment. Methane mitigation, waste recycling and water quality are popular areas of focus to help make the dairy industry more sustainable.

Since December 2020, feed efficiency has been recognized as a breeding trait in the U.S. It was initially identified to track the impact of feed savings throughout a lactation. Early estimates indicate that feed savings are about 19% heritable. Feed efficiency is vital for maximizing profitability. A University of Minnesota study found the top 10% of profitable dairy herds in Minnesota account for 60% of the feed costs of the bottom 10%. Additionally, feed efficiency influences environmental management. When less feed is required to produce the same amount of milk, a reduced environmental footprint results.
