    The format for this course is lecture-discussion. Student participation in class discussion is strongly encouraged. Students enrolled in this course typically represent a diversity of backgrounds and experiences. We all need to learn f-rom those diverse experiences. In many management situations, there are not right and wrong answers, there are differences in opinions and priorities. Hopefully our opinions are based on scientific facts and appropriate reasoning. Much of the grading in the course will be based on how well you defend the decisions you are making rather than coming to the same conclusion that you think the instructor would promote.

    Students are expected to give a 10-minute presentation at least once during the semester. The topic presented will be associated with the discussion for the day. If you have a health-related topic that you would like to present, please talk with me about it by January 15. If you do not have a topic to suggest, I will have several suggestions. Assignment of topics will be finalized during the second week of the semester. An outline and bibliography of the material reviewed for the presentation must be submitted to the instructor at the time of the presentation. It is expected that the major source of information for the presentation will be current scientific literature rather than books and popular press articles. Web site information is acceptable, if it is a quality site, but web sites should not represent the majority of the sources.

    The presentation should emphasize the important factors in theTiLhoZenesis and control of the health problem in the assigned topic.

There will be four quizzes, approximately 30 minutes long. The quizzes will be one or two questions presenting a herd situation and asking for your analysis of the problem(s) and for your recommendations for management programs to address the problem. Quiz dates will be announced and will occur after completion of the discussion of infectious disease, mastitis, reproduction and metabolic disease sections.

    Three reviews of current research articles are required; one each in the areas of reproduction, metabolic health and calf health. Articles reviewed must have a direct implication for herd health managem      . The student should review a research article of their choice from publications of the year 2000 and write a review of the article including the following information:

brief summary of the experimental design and results

impact of this research on dairy herd health management questions unanswered by this trial.

    If articles are reviewed from j oumals other than Journal of the American Veterinary Medical Association or The American Journal of Veterinary Research, please include a copy of the article with your report.

 

Due dates are listed in the schedule.

 

Course grade will be determined as follows: 

Quizzes                           10% each 

Research reviews                   5% each 

Class Presentation                10% 

Final Exam                        35%

All written materials must be: 

1. legible

2. complete

3. written in report style using proper grammar and spelling. Reports not meeting these standards will be graded accordingly.

 

ALL ASSIGNED WORK MUST BE COMPLETED IN ORDER TO RECEIVE A PASSING GRADE

 

    All cases of academic dishonesty will be handled according to current University Policies as outlined in Section 49-20 of the Penn State Student Handbook.

    

    A suitable text is not available. Outlines of the material to be presented will be available at the beginning of each section. Some references are cited in the outlines and students are encouraged to read these references for additional information. In addition, students are strongly encouraged to read articles in the current popular and scientific press. Suggested sources include:

Journal of Dairy Science

Journal of Animal Science

Journal of the American Veterinary Medical Association American Journal of Veterinary Research Preventative Veterinary Medicine Hoard's Dairyman

Dairy Herd Management

 

    I will ask for a discussion at the beginning of each Wednesday class on articles in the current literature that students have read related to the area of dairy herd health that is currently under discussion and that they would like to discuss.
