Course Description:

ASC 783C is a graduate course covering the broad topic of mineral and vitamin metabolism in ruminant and non-ruminant animals with more emphasis on farm and companion animals.

Office Hours: Friday (8:00 to 10:00 a.m.) Additional time is given by an appointment

Objectives for Student Learning:

  1. To develop in students a basic and practical understanding of mineral and vitamin metabolism in animals.  

  2. Students should be able to appreciate the significant roles of minerals and vitamins in maintaining health and productivity of animals.

  3. Students should be able to distinguish between symptoms of deficiencies and toxicities of minerals and vitamins.  

  4. Students should be able to know how to correct for symptoms of  deficiencies or toxicities by selecting the appropriate dietary ingredients and (or) supplementations.  

  5. Students should be able to use the gained knowledge to improve the nutrition of farm and companion animals.

Grading System:

The grades will be determined on the basis of 4 exams (100 points each), 4 oral presentations (25 points each) for a total of 500 points.  There will be 4 optional quizzes (5 points each; to encourage reading before attending the class) and an optional term paper (20 point) on one of the topics covered during the oral presentation sessions (for improving overall course grade).

Grading of Oral Presentation:

The oral presentation session will consist of a 12-min presentation covering the information reported in the selected journal article.  An additional 3 min will be allowed for questions and answers.  This should help the students to adapt to presentations in scientific meetings.  Students will be required to prepare slides and any additional overheads by using Microsoft PowerPoint.

Total points for each presentation = 25 pts.

- Organization and presentation

 = 10 pts.

- Visual aids

 = 5 pts.

- Answers to questions

 = 5 pts.

- Input during the 30-min manuscript evaluation session following the oral presentations

 = 5 pts.

.

Grading of Term Papers:

Any student wishes to write a term paper has to inform the instructor of his/her decision by March 16th.  Papers are to be written in a technical format.  Copies of the Style and Form for Journal of Animal Science will be provided to be used as a guide. 

Total points for the term paper = 20 pts.

- Organization

 = 5 pts.

- Contents

 = 10 pts.

- Style and Form

 = 5 pts.

.

Course Grades:

  A: 90% (450-500)

  B: 80% (400-449)

  C: 70% (350-399)

  D: 60% (300-349)

  F: <60% (< 300)
Reading Material:

Due to the diversity of the topics discussed in this course, no textbook is recommended. However, copies of chapters focusing on mineral and vitamin metabolism and (or) related issues from several books in print and off print and classical review articles will be provided to students along with handouts of each lecture. Students are responsible for all material covered in the classroom, the handouts, chapters, and articles provided.
