General Information : This course is intended for those who have both a
theoretical
and
practical interest in the sciences involved in the preservation of forages for
ruminant animals. Introductory material
and background will be presented in lecture.
Scientific literature and application of concepts will be covered in
discussions. Topics are presented for
general information and may be changed to meet class needs.
Course Objectives : The objectives of the course are (1) to provide students with the
scientific background associated with the processes involved in the
preservation of forage for ruminants (2) to help students understand and critique
research on the topic and (3) to enable students to solve practical problems
through the application of materials covered in the class.
Expected Learning Outcomes : Upon successful completion of the course.
1.
Students will be knowledgeable of the processes involved in the making of
hay and silage
2.
Students will know how to manage forage and control inputs that impact
hay and silage quality
3.
Students will know how to evaluate stored hay and silage
4.
Students will know how to use hay and silage to meet livestock needs and

Writing Assigments : Four papers are required. Each paper will constitute part of your grade as explained under
grading. Each paper will be graded on
scientific merit and clarity of presentation
Paper # 1.The topic of the paper is quick methods to determine moisture content of
forage. This paper is due September
12, 2001 and should be between two and three double spaced typed pages.
Paper # 2. You are in charge of developing an educational program for consultants
who wish to know about hay. Interests
include harvesting, storage, and nutritional value. Develop an outline of topics to cover and demonstrations you
would like to cover in the program.
Part of you assignment is to determine not only the topics but the time
needed in the program to present the topics.
In summary develop a complete workshop program on hay for the
consultants so they can provide information to clients. This paper is due October 3, 2001.
Paper # 3. You have taken a job as a silage
expert for a consulting firm that provides information to clients on all
aspects of silage making and use. You
decide to assemble major points in table form for quick reference. Include information on at least two types of
upright, horizontal and bagged silage operations or techniques. You should include information on
advantages, disadvantages, suitable crops for ensiling, additives, feeding
techniques and other items you consider important. (You might consider looking at a weed guide manual for ideas on
table arrangement). This paper is due October
24, 2001.
Paper # 4. Write a paper of 3 to 8 double
spaced typed pages in length on Diseases and Disorders associated with feeding
silage. This paper is due November
14, 2001.
