Fecal
Analysis
|
|
Several times we have attended classed on how to do
fecal samples and have purchased the equipment. The
most expensive piece of equipment is, of course, a
microscope. You do not need the most expensive one.
A couple of our goat friends have obtained high school
or college lab microscopes when they upgraded to newer
ones. We went to Walmart and picked up a microscope
with 4X, 10X & 40X power with a built-in light.
I think it was from C & A Scientific, but am no
longer sure. The microscope came with some blank slides.
The rest of the equipment we had around the house
or barn. Of course, some of the items we do not want
to bring back into human use.

To make your flotation solution you can use sugar
or salt. Put water in a pan and bring to a boil. Add
salt, or sugar and stir. Keep adding and stirring
until the salt or sugar is so saturated in the solution
that it will not dissolve. Pour off the clear part,
and store.
|
Now, collect your nanny berries. I use a small zip
lock bag turned inside out. I retrieve fresh berries
and write on the bag whose berries they are. I normally
collect four or five goats, thus I run four or five
samples through at the same time.
|
Next, I measure 3 grams of fecal material and put
into a 5-ounce paper cup. I use a Dixie paper cup.
Add 15 ml sugar/salt solution to the fecal matter.
Stir the solution and fecal matter until the material
has and even consistency. Using a kitchen tea strainer,
pour the solution through the strainer into another
5-ounce paper cup. Use a tongue depressor, popsicle,
or craft sticks to press as much material through
the strainer as possible. Let set for a couple of
minutes, stir, then pour the solution into a test
tub or small glass vial.
|
We got our test tube as a gift from our local County
Extension Center. Fill the test tube to slightly overflowing.
Place a coverslip on top of the test tube, making
sure the solution is touching the coverslip. Allow
to sit for about 15 minutes. The eggs will float to
the top of the solution and collect o the coverslip.
Carefully remove the coverslip and place it wet side
down on top of a slide. Place the slide under the
microscope. 10X is all that is needed for the initial
observation. Begin by moving the slide in a pattern
so you get a change to view the entire slide. Each
time you find worm, annotate it. To get a better look
at a worm egg, change the microscope to 40X.
|
You should be able to identify the worm eggs from
one of the many charts provided for ruminant animals.
I use the Guide to Internal Parasites of Ruminants
provide by InterVet. I got my copy from Mr. Furney
Register of Register’s Sheep and Goat Supplies -
http://www.lightlivestockequipment.com/Manuals/GuidetoInternal(obscured).pdf .
When you have covered the entire slide, check to see
how many eggs you saw and the types you saw. The major
parasites we have to deal with are barberpole (Haemonchus),
stomach (Ostertagia) and tapeworm (Moniezia). |
If I find fewer than 15 worms, then I do not worm
the goat, but if over 15, I would check her eyelids
and gums and worm based on both. Ok you say, then
why did we go through all of the messing with nanny
berries. Well we need to know what kinds of worms
our goat has. All goat have worms, it is just that
we don’t want them to have too many worms. If
I find an overload or something I am concerned about,
then I collect some more nanny berries from that goat
and take them to the vet for an ‘expert’
look at what we have and a recommendation as to a
wormer for that goat and its worm problems.
