Testimonial
of a Veterinarian
I
became aware of MJ Biologics in late 2006. After contacting
some veterinarians who were using the MJPRRS™
vaccine, I decided to try it on my own. In my practice, I work
with mostly independent producers who are primarily farrow to
finish systems and nearly all dealing with the effects of PRRS.
I had used conventional killed autogenous vaccines with only
marginal success and little cross protection. I was frustrated
by the unpredictable results of LVI and did not want to use
modified live vaccines. The MJ Biologics technology is unique
because it provides a mechanism to analyze different viruses
to select immunologically different virus strains to broaden
the protection in the MJPRRS™
vaccine.
In 2007, I used this product in 10 farms that had a history
of repeated clinical PRRS outbreaks in the past. I began using
the vaccine to blanket the sow herd periodically. We were able
to provent prental losses, stabilize the sow herd and protect
them from outbreaks from new or mutated virus challenges. The
number of farms using the vaccine has continued to grow and
during the last 3 years the vaccine has been applied in many
different situations to stabilize herds, get back to producing
PCR negative pigs more quickly, and reduce levels viremia.
In 2009 with more product availability we started to use the
vaccine in piglets. We are very pleased with the unexpected
results that we experienced. In the 20-year history of the PRRS
disease I have never witnessed a product that would accomplish
what MJPRRS™
would do in stopping death loss and clearing the virus in such
a short period of time.
The clinical picture was dramatically and rapidly improved after
vaccination even though some PCR tests remained positive. The
Virus Quantitation revealed that vaccinates has 100 to 1000
fold LESS virus in their serum compared to non-vaccinates.
In conjunction with other good production practices, this technology
provides the means to produce a multi-strain vaccine with a
high antigen content that can reduce the clinical and economic
impact of PRRS in a swine herd. My confidence in this technology
allows me to continue to apply this product in situations where
producers have been dealing with costly effects of PRRS.
