There is increasing public interest in the health benefits of whole and nutrient-dense foods. This study will test the levels of vitamin A and E, beta-carotene, and vitamin D-25 hydroxy in bulk tanks from twenty dairy farms under organic, conventional grazing, and conventional confinement management systems. Testing the milk from these different farms will teach producers how feeding and management affects milk quality. Outreach will be through scientific meetings, industry magazines, newsletters, a field day, and the Web.
