Survey of scientific literature regarding carcass composition; quality and palatability of meat animals; factors that affect differences among animals of the same specie; the impact on value and usefulness.
Lectures will consist of discussions of research papers and material from the textbook and other reading assignments. Students are encouraged to enter into discussions, and, at times, will be asked to make short presentations regarding research information especially if it relates to an area they have conducted research or have a special interest in.
The tests are take-home and are designed to allow the student to gather information from many sources and answer complex questions regarding carcass composition and quality/palatability. The tests will be given to the student near the end of each module and will be due one week later. This method of testing is the best way to measure learning of this complex material. Although students are requested to do their own work, I encourage joint discussions among students regarding complex issues. This interchange improves the learning process.
Each student will be required to write a research paper covering some issue that is related to the subject matter material from this course. The paper is due on the last day of lecture (April 26) and will comprise one-fifth of the final grade. The papers are to be typed, double-spaced and be between 10-20 pages including tables, figures and references. Students must follow the current Journal of Animal Science or Meat Science style guides. Grading of the paper will be as follows: depth and completeness of review, 40 points; subject matter, 25 points; grammar and neatness, 15 points; adherence to the journal style guide, 10 points and meeting deadlines, 10 points. The papers should be of high enough quality that they could be submitted to the journal as review articles.
Each student must provide a proposed title by February 6 and a proposed outline by April 5. A near final draft of the paper is due April 19 that I will return in one week with my comments for the students use in finalizing. These steps are to help students meet the final deadline with a quality paper.
The schedule will be as follows:
| Item | Worth | Date Given | Date Due |
| Research paper | 100 points | January 16 | April 26 |
| Examination A | 100 points | February 6 | February 13 |
| Examination B | 100 points | March 1 | March 8 |
| Examination C | 100 points | April 5 | April 12 |
| Examination D | 100 points | April 26 | May 8 |
| Total | 500 points |
Grades will be assigned as follows: 450 points or higher = A; 400 to 449 points = B; 350 to 399 points = C; 300 to 349 = D; and less than 300 = F.
Because this is a graduate course, it is difficult for graduate students to be in class every time it meets. I encourage class attendance because this is a good way to learn from the interchange of ideas. I also understand the necessity to be gone from class conducting the research that will be used in this and following semesters to help increase the knowledge-base of students. Students who miss should check with me to obtain handout materials they miss.
