Hi! You are most likely wondering what this insert is that is being sent
out with your report. Well, it is an informative bulletin that we technicians
at I & A lab have developed to keep you informed about exciting topics
that are happening in the milk production world. This first bulletin you
have received today is on the topic of mastitis and somatic cells. I hope
that you find it interesting and informative.
Mastitis -
What is mastitis? Well, mastitis is an inflammation of the mammary gland
usually caused by bacteria. Also, any injury to the udder, the use of
too high a vacuum with milking machines, or leaving the machine on after
the flow of milk has stopped tends to favor mastitis. It is important
to dairymen because this disease is very significant to the economy of
milk production. Mastitis is the most common and the most costly cattle
disease in the United States. It has been estimated that the average cost
per cow is equal to 1540 pounds of milk and the American Dairy Industry
estimates about one-half billion dollars per year are spent. Mastitis
affects milk composition, which decreases the quality of the milk for
processing.
Somatic Cells
- Now that we have reviewed what mastitis is, the next thing you're probably
wondering is what are somatic cells and how are they related to this udder
disease. Somatic cells are produced all of the time and they are shed
in healthy milk. They are important because they play a critical part
in fighting the harmful bacteria that cause mastitis. The increase in
numbers of somatic cells is a response by the body to combat the mastitis
infection. Even though the legal limit for somatic cell count is 600,000
in order to ensure maximum milk production and health of your herd, somatic
cell counts of about 100,000 are recommended. Counts that tend to be higher
than 300,000 may indicate a slight mastitis infection and are generally
considered to be on the high side of the spectrum.
Now let me explain
a little more about somatic cells to you. There are two types of somatic
cells. The first is called a leukocyte, which is a white blood cell. This
type of somatic cell knows that the bacteria are the bad guys and it tries
to ward off these invaders. This type of cell is beneficial to the health
of the cow, yet its increase in numbers indicate an infection. The second
type is the epithelial cell, or "damaged milk cell." These are
the cells, which normally help produce the milk, however, during a mastitis
infection they fail to produce milk because of the irritation. When we
count somatic cells we are actually counting both the leucocytes and the
damaged milk cells.
Finally, what measures
should you take to prevent such an infection from occurring? Here at A
lab, & I we offer two tests to accommodate your specific needs. The
first can be performed within about fifteen minutes and is a basic screening
test to suggest that there might be mastitis. The second test is more
accurate and the results give a number according to the somatic cell count.
This is called the DMSCC method. So, simply by bringing in a sample of
your milk, we can determine whether or not your herd has a mastitis infection
based on the screening and the Direct Microscopic Somatic Cell Count (DMSCC).
DMSCC is usually performed once a week and will assure you of the quality
of your milk and save you time, money and the loss of milk production
if you ever run into the common problem of mastitis in your herd.
It is important to
note that the symptoms of mastitis are not always visible to the dairymen.
Usually, symptoms only occur in the advanced or life-threatening stages
of the disease. With DMSCC, we are able to inform you of mastitis before
it can ever reach this point. So, in order to secure the quality of your
milk and allow you peace of mind, take advantage of our somatic cell test
to keep your dairy in the best possible condition. If you have any questions
or comments, please feel free to call us at (909) 947-6065 and we will
be more than happy to talk with you.
