ANS 6718 - NUTRITIONAL PHYSIOLOGY OF DOMESTIC ANIMALS
(Spring 2012 - MW - Period 4: 10:40 – 11:30 am Rm. 201 BLDG 499)
INSTRUCTOR: Dr. Lokenga Badinga, Associate Professor
Rm. 204B, Building 499 (Larson Dairy Science Bldg.)
Phone: 392-1958 ext. 252; E-mail: lbadinga@ufl.edu
Office Hours: As needed between 9:00 am and 5:00 pm on week days
CATALOG DESCRIPTION: CREDIT: 2; PREREQ: Animal Nutrition (ANS 5446) and
Gastrointestinal Physiology of Domestic Animals (ANS 6716).
An integration of physiological, biochemical and molecular control of nutritional
processes in monogastrics and ruminants.
COURSE FORMAT:
Two one-hour lectures per week. The general format will be a combination of
lectures and discussions on current concepts in nutritional physiology and
metabolism in monogastrics and ruminants.
EXPECTED OUTCOMES:
Upon completing this course, graduate students are expected to:
1. Understand the physical, biochemical, and molecular factors which control
intake, digestion and metabolization of nutrients in monogastrics and
ruminants.
2. Appreciate how current developments in recombinant DNA technology can
be used to improve the nutritive value of animal and human diets.
3. Develop independent thinking and conversational skills.
RECOMMENDED TEXT: NONE
There is no required textbook. Many of the sections are described in detail in:
1. ADukes= Physiology of Domestic Animals@ , 11 th ed., by Swenson & Reece, 1993.
2. ARuminant Physiology”, by Sejrsen, Hvelplund & Nielsen, 2006.
3. “Textbook of Veterinary Physiology”, 4 th ed., by Cunningham & Klein, 2007.
ASSIGNED READINGS:
During the semester, each student or group of students will be required to present a
scientific journal article that relates to nutritional physiology of domestic species.
The papers will be selected from a variety of scientific journals and assigned
randomly to students. On the day of discussion, students will have 30 - 40 min to
present the paper (summarizing the objectives, experimental design, key results,

and conclusions). The presiding students will then have about 10 - 20 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. One day before
the paper discussion, the presenter(s) will be required to turn in a one-page
summary of the article and the power point slides which will be presented. These
can be sent to the Instructor via e-mail the day before the paper discussion. The
presentations will be worth 50 points (or 12.5% of the final grade). Students are
expected to participate actively in all discussions to receive full credit.
Journal articles for discussion
1. Carnitine palmitoyltransferase I in liver of periparturient dairy cows: Effects of
prepartum intake, postpartum induction of ketosis, and periparturient disorders
(Dann and Drackley, J Dairy Sci 2005; 88:3851-3859).
2. Hexose transporter expression and function in mouse small intestine: Role of
diurnal rhythm (Fatima et al, J Gastrointest Surg 2009; 13:634-641).
3. Milk performance and glucose metabolism in dairy cows fed rumen-protected fat
during mid lactation (Lohrenz et al, J. Dairy Sci 2010; 93:5867-5876).
4. Gluconeogenesis in dairy cows: The secret of making sweet milk from sour dough.
(Aschenbach et al, Life 2010; 62:869-877).
5. Glucose transporters and enzymes related to glucose synthesis in small intestinal
mucosa of mid-lactation dairy cows fed 2 levels of starch (Lorenz et al, J Dairy Sci
2011; 94:4546-4555).
6. Involvement of skeletal muscle protein, glycogen, and fat metabolism in the
adaptation of early lactation of dairy cows (Kuhla et al, J Proteome Res 2011;
10:4252-4262).
GRADES:
The final grade will be based on performance in all areas of the course as follows:
Hourly exams 2 @ 100 pts = 200 pts (50.0%)
Final exam 1 @ 150 pts = 150 pts (37.5%)
Paper discussion 1 @ 50 pts = 50 pts (12.5%)
Grading scale:
A = 95-100%; A - = 90-94%; B + = 86-89%; B = 80-85%; B - = 76-79%; C + = 70-75; C = 66-
69%; C - = 60-65%; D + = 56-59%; D = 50-55%; D - = 46-49%; E =

Make-up Exam Policy:
No make-up examinations will be administered. For university functions or excused
absences, arrangements can be made to double the grade of the subsequent
examination. Verification of illness in the form of a note from the physician or form
for athletic activity or university-sponsored events will be required a week prior to
the scheduled exam. Detailed information on excused absences can be found on

ACADEMIC HONESTY, SOFTWARE USE, UF COUNSELING SERVICES, SERVICES
FOR STUDENTS WITH DISABILITIES
Academic Honesty:
In 1995 the UF student body enacted a new honor code and voluntarily committed
itself to the highest standards of honesty. When students enroll at the university,
they commit themselves to the standard drafted and enacted by students. In
adopting this honor code, the students of the University of Florida recognize that
academic honesty and integrity are fundamental values of the university community.
Students who enroll at the university commit to holding themselves and their peers
to the high standard of honor required by the honor code. Any individual who
becomes aware of a violation of the honor code is bound by honor to take corrective
action. The quality of a University of Florida education is dependent upon
community acceptance and enforcement of the honor code.
The honor code: “We, the members of the University of Florida community, pledge
to hold ourselves and our peers to the highest standards of honesty and integrity.”
On all work submitted for credit by students at the university, the following pledge is
either required or implied: “On my honor, I have neither given nor received
unauthorized aid in doing this assignment.”
The university requires all members of its community to be honest in all endeavors.
A fundamental principle is that the whole process of learning and pursuit of
knowledge is diminished by cheating, plagiarism and other acts of academic
dishonesty. In addition, every dishonest act in the academic environment affects
other students adversely, from the skewing of the grading curve to giving unfair
advantage for honors or for professional or graduate school admission. Therefore,
the university will take severe action against dishonest students. Similarly,
measures will be taken against faculty, staff and administrators who practice
dishonest or demeaning behavior.
Students should report any condition that facilitates dishonesty to the instructor,
department chair, college dean or student Honor Court.

It is assumed all work will be completed independently unless the assignment is
defined as a group project, in writing by the instructor.
This policy will be vigorously upheld at all times in this course.
Software Use:
All faculty, staff and students of the university are required and expected to obey the
laws and legal agreements governing software use. Failure to do so can lead to
monetary damages and/or criminal penalties for the individual violater. Because
such violations are also against University policies and rules, disciplinary action will
be taken as appropriate.
Campus Helping resources:
Students experiencing crises or personal problems that interfere with their general
well-being are encouraged to utilize the university’s counseling resources. Both the
Counseling Center and Student Mental Health Services provide confidential
counseling services at no cost for currently enrolled students. Resources are
available on campus for students having personal problems or lacking clear career
or academic goals, which interfere with their academic performance. The
Counseling Center is located at 301 Peabody Hall (next to Criser Hall). Student
Mental Health Services is located on the second floor of the Student Health Care
center in the infirmary.

accommodations within the classroom, accessing special adaptive computer equipment,
providing interpretation services, and mediating faculty-student disability related issues.
