Research Interests
Dr. Schroeder's emphasis:
As the North Dakota contributor to our regional NC-185 program, my research
focuses on:
Metabolic Relationships in Supply of Nutrients for Lactating Cows
The specific objective relates to Objective 2a:
To quantify relationships in partitioning of nutrients between body tissues
and milk synthesis.
Post-absorptive metabolism
DESCRIPTION:
Role of High Linoleic Oilseed in Milk Lipid Metabolism.
The concentration of conjugated linoleic acid (CLA), an anti-cancer and anti-obesity factor, can be increased in milk by including certain oilseed in the dairy cow diet. The objective of this research is to develop a dietary regimen that increases conjugated linoleic acid content in milk fat.
Lactating Holstein cows will be used to investigate the effects of dietary oilseed supplementation using whole or minimally processed (crushed) oilseed that contains fatty acids high in linoleic acid. The oilseed will represent crops of agronomic importance and regional availability, including: canola, sunflower, safflower, and soybean. Feed intake, milk weights, blood metabolites, milk composition to include milk fatty acid profile and body weight/body condition scores will also be determined.
The long-term significance of this research is to aid in the improvement of
the nutritional value of milk as a functional food for human consumption and
nutraceutical.
