Scientist Works To Improve Nutrients In Beef

PULLMAN – “You are what you eat” pretty well sums up research being conducted by WSU animal scientist Mark Nelson.

Nelson, an associate professor in the Department of Animal Sciences, is investigating new ways to reduce the saturated fat content in beef by changing what cattle eat. Specifically, he is working on increasing levels of conjugated linoleic acid, omega-3 fatty acids, vitamins A and E and antioxidants.

What I do is manipulate the chemical composition of what goes into the rumen (first stomach), said Nelson. However, I use only feedstuffs that are native to Washington State, so my research is applicable to the cattle industry here. I am interested in what we can do with the average animal in the industry to improve their products.
