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.
