In order to complete this virtual lab, students will
have first thoroughly read the following modules in on the Animal Nutrition
CD, ©Patricia Schoknect, Rutgers University of New Jersey, The Mid-Atlantic
Consortium 2002.

2. Assessment
of Nutritive Value
3. Digestive
Anatomy
4. Rumen
Fermentation
Students are to first look at the virtual lab form. On the instructions page for the lab
report is a printer icon to view a printable version of the lab report. This might be useful to jot down your
observations as you are retrieving the test results from the virtual lab.
Take a look at the Rubric page to see how you will be accessed.
When
you are ready to begin, go to the virtual lab page and begin your analysis.
- Determine from your
reading why this analysis of feed and how it reacts in the rumen
environment is important. This
will be your purpose.
- Look at all the
different feed on the lab page available for you to introduce to the
rumen environment. The choices
include forages and concentrates.
You will test each feed for pH, Ammonia and Methane. Choose at least 6 different feeds and
make an educated guess or prediction “hypothesis” of what the outcome of
the different tests will be.
- Describe the
materials, procedures and steps.
- Make observations
on the different outcomes of each feed.
- Analyze and
compare the feeds against each other.
Explain what your data means. Interpret your data. Explain any
results that were not predicted.
- Finally, in one or
two sentences explain if your results agree or disagree with your
hypothesis
- Fill out the online
lab form and submit. Print out
the confirmation page and submit to you teacher.
- Finally, after
finishing the lab report, you will submit a
self-evaluation of your work by using the self-evaluating rubric found
on this site.
As
always, if you have any questions, please feel free to ask the instructor.
