Porcine
Reproductive and Respiratory
Syndrome (PRRS) is the mosteconomically significant disease
to affect US swine productionsince the eradication of classic
swine fever.
As indicated by its name, PRRSleads to reproductive failure,
including abortions andstillbirths In young pigs.
(00:28):
It can cause respiratory issueslike pneumonia and can increase
susceptibility to secondarybacterial infections.
Welcome to Feedstuffs In Focus,our podcast taking a look at
the big issues affecting thelivestock, poultry, grain and
animal feed industries.
I'm your host, sarah Muirhead.
This episode is brought to youby Pharmgate Animal Health, a
growing business that putslivestock first.

(01:11):
Joining us today to talk aboutPRRS and options for protecting
your herd is Dr Nic Lauterbach,Technical Services Veterinarian
with Pharmgate Animal Health.
So, Nic, tell us about yourrole at Pharmgate and your
experience in battling PRRS.
Dr. Nic Lauterbach (01:28):
Yeah hi
thanks for having me.
I'm Dr Nic Lauterbaum, atechnical service veterinarian
with Pharmgate Animal Health.
I've been with the companyabout two and a half years.
Prior to that, I was aveterinarian within a production
company in the Midwest for fourand a half years, and so I've
been in the swine industry forseven years just about seven
years and so with that obviouslycomes a lot of experience
(01:52):
battling purrs, especiallyraising pigs in the Midwest, so
had a lot of experience on boththe sow side as well as the
finishing pig side, and I thinkthat that can be said about a
lot of other folks on our teamwithin Pharmgate as well.
I think that's one thing thatreally sets our group apart is
(02:14):
when you're talking about theseprevalent pathogens,
specifically with PRRS, right,we have a lot of in-barn
real-world experiences.
That, I think, positions usuniquely to really bring these
science-based solutions and talkabout some of the ways to
manage this really impactfuldisease that we're going to talk
about today.
Sarah Muirhead (02:33):
So what have you
been hearing out there from
customers about PRRS challengesand prevalence?
Dr. Nic Lauterbach (02:45):
I would say,
interestingly, the one thing
that I would say we hear a lotthat has probably changed, even
in my fairly brief career isthat we talk about PRRS year
round.
Now it really does not seemthat there is an off season for
PRRS.
People are focused on keepingPRRS out, managing PRRS, working
through PRRS breaks pretty muchfrom.
(03:05):
You know it used to be.
We dealt with it a lot in thewinter times as the weather got
cold and as the season shifted.
It just seems like anymore it'sa 12 month a year.
Conversation that we're havingis around PRRS and how do I
manage this better?
Sarah Muirhead (03:21):
And it's all
sizes of operations right.
Dr. Nic Lauterbach (03:24):
Yeah, it's
all sizes of operations, right?
Yeah, it's all sizes ofoperations, and really it's in
every state that we raise pigs.
I think there's very few statesanymore that are untouched by
the PRRS virus, and especiallywith I'm located in central Iowa
.
A big portion of our team isfrom South Dakota to Iowa to
(03:44):
Oklahoma, so we spend a lot oftime talking about PRRS.
Sarah Muirhead (03:49):
So what kind of
clinical signs should producers
be looking for as they monitorfor PRRS in their herd?
How best to have that diagnosed?
Dr. Nic Lauterbach (04:05):
Yep.
So PRRS stands for porcinereproductive and respiratory
syndrome virus, and so that inthe name kind of tells you what
disease processes we need tolook out for.
So when I think about the southside of things is really where
you can see both, both of thosediseases or both of the uh
pieces of the name kind ofmanifests itself where you have
the reproductive disease, whichreduced conception rate, loss of
(04:26):
litters and just overall areduction in the number of pigs
weaned from the sow farm.
But also you can see therespiratory side of things where
it tends to be really hard onsows and weaned pigs alike,
where you'll typically seelethargic, off-feed sows.
You could see an increase inpiglet mortality in the
(04:46):
farrowing house and just reallya really significant impact on
the number of pigs that wereweaning from the sow farm.
When you get out into thefinishing side of things,
obviously you're going to seemore on the on the respiratory
side, where you'll see a reallyreduced activity, lethargic pigs
, reduction in water intake,reduction in feed intake and in
(05:09):
the worst cases has thepotential to see some really
significant mortality.
That is associated with thePRRS but then is also partially
associated with some of thesesecondary bacterial infections
that comes with this virus'sability to really hamper the
immune system of this pig torespond to bacterial pathogens
(05:32):
that it otherwise would have noproblems fighting off.
Sarah Muirhead (05:36):
Yeah, let's talk
about that a little bit, those
secondary infections.
What's the overall risk fromthose?
Dr. Nic Lauterbach (05:43):
Yeah, the
risk is huge and really that's
the piece when we talk about anactive PRRS infection.
That's the piece we feel likewe can manage the best, or try
to attempt to manage the bestRight we have.
That's where our antibiotictreatment regimens would come in
, come into play when you havethese secondary bacterial
infections that, like I said,the pig would routinely come
(06:04):
into contact with.
But when you add a PRRSco-infection on top of this,
that immune system is just notfunctioning to the highest level
and that's when those bacterial, that bacterial pressure can
then really pose an issue tothese pigs.
Sarah Muirhead (06:18):
How important is
PRRS prevention versus
treatment, and is it possible tofully eliminate PRRS from a
system when you have it there?
Dr. Nic Lauterbach (06:29):
Yeah, I
would say PRRS prevention is the
number one thought that almost.
We talk to a lot of peopleacross the country and I don't
know of anybody that's notactively working to keep PRRS
out, whether they've had PRRSbefore or they haven't had PRRS
in the history of the farm.
Everybody has some plan inplace or some steps in place to
(06:50):
keep PRRS out of their farmbecause prevention is the best
way to manage this right.
If you keep PRRS out, you don'thave to worry about managing it
.
You don't have to worry abouteliminating it.
With that said, I do think thatfrom an industry standpoint, we
all recognize and realize thevalue that being PRRS negative
has, and I do think that we areworking towards being PRRS
(07:14):
negative.
There's just a lot of differentfactors that go into that right
.
Sarah Muirhead (07:19):
What are some of
the strategies that you
recommend when it comes to thecontrol of PRRS?
Dr. Nic Lauterbach (07:25):
Yeah.
So probably steps one, two,three, however many they are is
biosecurity Keeping this diseasewe mentioned it prevention If I
can keep this disease out of myfarm and I remain PRRS negative
, I don't have to worry abouteliminating it, I don't have to
worry about managing it.
So trying to put as many layersbetween the pig and potential
(07:46):
PRRS introduction is critical.
So having those biosecurityplans that are evaluated
routinely, making sure we don'thave any gaps and making sure
that our risks to our systemhaven't changed, is really
critical.
The second piece of that wouldbe a vaccination strategy, and
(08:07):
this would be widely used by theindustry as well, where you
know, if we know, we're going todo everything we can to keep
PRRS out of our system.
But based off your geography,your pig density, where your
farms are at, you will likelyhave some inherent risk of PRRS
being introduced into your farm,and so I think what ends, what
(08:27):
a lot of people then movetowards on the management side,
is PRRS vaccination, trying tomake sure that if those pigs
come in contact with a wild typePRRS, we have set them up for
as much success as we canpossibly have.
Sarah Muirhead (08:43):
So what kind of
strategies, then, or what kind
of solutions, does Pharmgateoffer to protect herds against
PRRS?
Dr. Nic Lauterbach (08:50):
So, in terms
of the, I think that's the one
exciting thing that I reallyenjoy about working for
Pharmgate Animal Health is whenit comes to managing PRRS,
managing through PRRS breaks.
We do have a extensiveportfolio that can be beneficial
in a lot of scenarios.
And so we have antibiotics likewe talked about, the secondary
(09:11):
bacterial bacterial infectionsand the roles that those play in
making this disease and theseco-infections worse, and so we
have, you know, water solubleantibiotics like Penn, chlor 64
and Avosyn that are labeled fora broad range of those bacterial
pathogens.
But then we also do on thevaccination side.
(09:35):
We are excited about havingPRRS Guard, which is our
modified live PRRS vaccineavailable to the industry.
And, yeah, that we have beenable to show is efficacious in
the face of a lot of theserelevant wild type PRRS strains
(09:55):
that we're seeing out in theindustry today.
Sarah Muirhead (09:58):
How exactly does
PRRS Guard work?
Dr. Nic Lauterbach (10:02):
So PRRS
Guard is a lineage one, chimeric
modified live PRRS vaccine, andso the goal with it, along with
a range of our other commercialvaccines in the swine industry,
is just to allow that pig tobuild an immune response before
it comes into contact with awild.
That PRRS Guard has the abilityto cross protect against some
(10:23):
of these significant wild typePRRS strains, such as a 174 PRRS
, and most recently we conductedcompleted a research study that
shows efficacy in the face of a144 L1C PRRS strain.
Sarah Muirhead (10:46):
So what about
product safety performance
effectiveness?
Talk to us more about thatstudy product safety,
performance, effectiveness.
Dr. Nic Lauterbach (10:54):
Talk to us
more about that study.
Yeah, sure so.
Pharmgate Animal Health takes alot of pride in the safety and
the efficacy of our vaccinesthat we bring to market.
We have a really robustprotocol that we follow to make
sure that the vaccines that weare bringing out are safe and
that they work well in thesituations that we need them to
work well for the industry.
(11:14):
Right, we want to be seen asbeing a resource and being a
value-added partner to producersand veterinarians alike, and so
that's where the trial I justreferenced is some of the most
recent work we've done withPurr's Guard, where we challenge
pigs with a relevant purrstrain Guard, where we
(11:35):
challenged pigs with a relevantPRRS strain 144 lineage 1C that
we see a lot of in the Midwest,and we showed success with PRRS
Guard vaccinated pigs inreducing the impact that that
PRRS has against not only thenon-vaccinated PRRS control pigs
but also had six.
We were.
We were as efficacious asanother relevant commercial PRRS
(11:57):
modified live that's on themarket, and so we're really
excited about that because Ithink ultimately, we want to be
seen as a an option for peoplethat are looking for hey, you
know how do I.
How do I maximize the toolsthat are available to us and the
tools that are in my toolbox?
Sarah Muirhead (12:17):
Very good.
Anything else you'd like to addand leave our listeners with
here today.
Dr. Nic Lauterbach (12:22):
Yeah, I
would just leave everybody that
if you ever have any questionsabout who we are as a company or
our experiences, you knowPharmgate, Pharmgate Animal
Health.
I think we are uniquelypositioned that not only me and
my experiences, but really ourentire team.
We have a lot of in barnexperience as it relates to the
(12:44):
swine industry, so our wholeteam has been around the, has
been around agriculture for mostof our careers and a majority
of us have spent our careersspecifically in the swine
industry at all different levels, at all different, you know, at
all different phases ofproduction.
So we feel that we can be a realresource and a value added to
(13:05):
add value to producers andveterinarians alike.
We have a robust portfolio and,specifically when it comes to
managing and getting throughthese PRRS breaks, I think
that's where partnering withsomebody like us, where we have
the PRRS vaccine on the frontside and then if things were to
happen and we need to react andwe need to try to limit these
impacts, we have antibioticsthat could also be implemented
(13:28):
to try to reduce that impact.
So if you have any morequestions or if you would like
to just learn more about howPharmgate can be a resource for
you.
