ANS 6718 NUTRITIONAL PHYSIOLOGY OF DOMESTIC ANIMALS

INSTRUCTOR: Dr. Lokenga Badinga, Assistant Professor Rm. 104C, Building 499

Phone: 392-5594; E-mail: badinga@animal.ufl.edu

An integration of physiological, biochemical and molecular control of nutritional processes in domestic animals.

COURSE FORMAT:

Three one-hour lectures per week. The general format will be a combination of lectures and discussions on current concepts in digestive physiology and metabolism in farm animals.

COURSE OBJECTIVES:

• To provide a comprehensive overview of current concepts in the physiology, biochemistry and molecular biology of nutritional processes relevant to livestock and poultry.

• To discuss endocrine and metabolic adaptations to daily variations in feed intake and composition.

• To discuss and understand how dietary and hormonal factors interact to control nutrient partitioning and metabolism in domestic animals.

• To critically review the applications and limitations of biotechnology in animal and human nutrition.

EXPECTATIONS FOR PERFORMANCE IN THIS CLASS:

Upon completing this course, graduate students are expected to:

• Develop a clear understanding of motor, secretory and digestive functions of the gatrointestinal tract.



• Be able to understand and discuss the physiological and molecular adaptations to dietary carbohydrates and lipids.



• Be able to appreciate how current developments in recombinant DNA technology can be used to improve the nutritive value of animal and human diets.



• Be able to read, interpret and discuss scientific journal articles in nutritional physiology and molecular biology.

RECOMMENDED TEXT: NONE

There is no required textbook. Many of the sections are described in detail in:

• "The Ruminant Animal: Digestive Physiology and Nutrition" by D.C. Church.
• "Physiology of the Gastrointestinal Tract" by L.R. Johnson.
• "Dukes' Physiology of Domestic Animals" by M.E. Swenson & W.O. Reece.
• "Nutritional Biochemistry" by T. Brody.

CURRENT CONCEPTS IN NUTRITIONAL PHYSIOLOGY:

During the semester, each student will be required to present a scientific journal article that relates to nutritional physiology of domestic animals. The paper should be selected and given to the instructor at least one week before the class period scheduled for the presentation so that the instructor may distribute the paper to the class. On the day of discussion, the student will have 20 min to present the paper (summarizing the objectives, experimental design, key results, and conclusions). The presiding student will then have about 10 min to lead the discussion regarding the appropriateness of experimental approaches as well as the biological significance of the work. Other students will be expected to read the paper in advance and prepare several points for discussion. These presentations will be worth 100 points (or 20% of the final grade

GRADES:

The final grade will be based on performance in all areas of the course as follows:

Mid-semester exams 2 @ 100 pts = 200 pts (40%)

Final Comprehensive exam 1 @ 200 pts = 200 pts (40%)

Paper discussion 1 @ 100 pts = 100 pts (20%)

Grading scale: A (90-100%); B+ (86-89%); B (80-85%); C+ (76-79%); C (70-75%); D+ (66-69%); D (60-65%); E (<60%).

ACADEMIC HONESTY:

As a result of completing the registration form at the University of Florida, every student has signed the following statement: " I understand that the University of Florida expects its students to be honest in all their academic work. I agree to adhere to this commitment to academic honesty and understand that my failure to comply with this commitment may result in disciplinary action up to and including expulsion from the University."
