The overall intent of this course is to discuss the intricate and dynamic regulatory mechanisms that modulate intermediary metabolism in ruminants (sheep and cattle). It is designed to serve as a link between the “basic biochemical science” (metabolic pathways, etc.) and “applied sciences” relevant to livestock production. Objectives: Discuss and interact ruminant nutrition with metabolism, the performance of new approaches and technologies, as well as, feed strategies, metabolic disease and efficiency.
A successful student in this course will be able to:
• Compare and contrast how dietary feed is converted to body structures, energy, and energy stores within ruminants and non-ruminants.
• Describe how energy stores are used when needed under various physiological conditions (exercise, fasting, starvation, pregnancy, and lactation).
•Discuss how metabolic processes are regulated to meet the body's need under maintenance, growth, and productive metabolic conditions. Instructional Methods: This course will be team-taught by 2 faculty members and lectures will be the basis of instruction. Students are expected to read the reading assignments before class to encourage discussion during lectures. Guest lecturers will contribute in areas of their expertise.
