Key Findings

When the ration fed to dairy cows contains essentially 100% grass and forage-based feeds, milk has more than double the content of key, heart-healthy fats — in particular the polyunsaturated fats known as omega-3s, and conjugated linoleic acid, or CLA.

Nutritional modeling shows that the significant increase in the levels of omega-3s and CLA in grassmilk, and grassmilk-based dairy products, could have a big impact on health trends by enhancing the overall quality of fat in the American diet.

Study findings are presented below in short and long versions and multiple formats: prezi, video, PowerPoint (PPT), and PDF. Please feel free to download and use these presentations.
