PRRS Virus Filter for Incoming Air

Porcine Reproductive and Respiratory Syndrome (PRRS) is a swine disease responsible for some of the highest economic losses in global pig production.  In particular, breeding companies, multipliers and centers for artificial insemination must do everything possible to make sure that they maintain a negative PRRS status.

As a review, what is PRRS?  prrs virus

PRRS was first isolated and classified as an antivirus as recently as 1991 but first recognized in the USA in the mid 1980’s and was called “mystery swine disease”. It has also been called blue ear disease.

The virus of PRRS has the greatest affect on the pig’s lungs and reproductive system.   A major part of the bodies defense mechanism is destroyed and allows bacteria and other viruses to proliferate and do damage.  PRRS tends to remain present and active indefinitely.

The clinical picture can vary tremendously from one herd to another. As a guide, for every three herds that are exposed to PRRS for the first time one will show no recognizable disease, the second would show mild disease and the third moderate to severe disease. The reasons for this are not clearly understood. However the higher the health status of the herd, the less severe are the disease effects. It may be that the virus is mutating as it multiplies, throwing up some strains that are highly virulent and some that are not.

PRRS infects all types of herd including high or ordinary health status and both indoor and outdoor units, irrespective of size.

The main affects are decreased farrowing rates, increased mortality, attrition, and increased respiratory disease.

Economic effect of PRRSprrs graphic

PRRS is the most economically important disease now affecting swine producers.

According to The Economic and Production Impact of Porcine Reproductive and Respiratory Syndrome on Nursery and Grower-Finisher Pigs by Radu Zorzolan, A Thesis Presented to The University of Guelph

“The reduction of profits due to a PRRS outbreak was US $236 / female, which represented an 80% reduction in expected profits in the year of the outbreak.”

The same study estimated the cost of PRRS infection in the grower-finisher population to average $6.25-15.25 per pig (combined nursery and finishing stage).

Does an PRRS air filter work to keep your heard PRRS negative?

Throughout the swine industry, extensive efforts have been made to protect genetic and commercial swine herds from infection with different pathogens. However, local spread of certain pathogens such as PRRSV between farms still occurs due to aerosol transmission (Dee et al. 2006c). To reduce the risk of airborne spread, swine producers around the world are beginning to implement systems to filter the air entering their facilities. France was the first country that reported the use of air filtration in nucleus herds and boar studs. Since 1996, Cooperl- Hunaudaye, implemented air filtration in 11 herds that were populated with PRRSV negative animals after the system was installed. Air Filtration for PRRS Control 155 These herds are situated in Brittany, the most populated swine area in France; all have preserved their PRRSV negative status since then. As of today a considerable number of artificial insemination centers and farms in Europe, Quebec and the United States have implemented this technology since, in spite of extreme biosecurity rules, they experienced among others PRRS outbreaks without finding a logical explanation (Desrosiers, 2004a).

Dwyer Manufacturing offers an PRRS virus air filtraton system designed by Big Dutchman, Germany.

Below is a summary of information on Big Dutchman’s Air Pro Tec system.  CLICK HERE to find complete brochure

With Air Pro Tec, Big Dutchman offers an efficient fresh air filter which significantly reduces the introduction of PRRS viruses – by up to 95%

With Big Dutchman’s pressurized system, there are no exacting requirements regarding the air-tightness of the  building.

airprotec4

The air filters consist of the following main parts:

  1. Wind protection netting – prevents the entry of coarse foreign matter

  2. Prefilter – filters particles with a diameter of 3 microns and any PRRS viruses adhering to them

  3. Main Filter – filter fine particles up to 0.3 microns and any PRRS viruses adhering to them

  4. Cooling Module – fresh air can be cooled as required

  5. Ventilation pipe with fan and cover flap

prrs filter expained

The Air Pro Tec filters come in three sizes to be used in a centralized or decentralized systems.

The centralized systems ( APT 10 000 and APT 20 000) works well in facilities where cooling is necessary.  Air capacity of each is 10,000 and 20,000 m3/hour respectively.

In Summary,

While the additional capital cost of a PRRS virus air filtration system can be significant, the cost benefit of keeping your PRRS virus negative status can be more over the lifetime of the filtration system.  Remember the study that shows $236 / sow / year in production lose is possible the first year of outbreak.

$236 x 500 sows = $118,000 in the first year alone plus over 10 years = $1,180,000 in production lose plus the value of a negative PRRS status.

Pig Barn Winter Ventilation

Winter Ventilation in Pig Barns 

As herdsmen(women) we have been entrusted with the day to day well-being of the staff, who work each day in the barns and the animals in our care.

During cold Canadian winters, providing quality air in the grower and finisher rooms can seem like a balancing act between clean air and energy costs.  For the sake of you and your staff  and the health and performance of your animals, proper air quality should be basic fact.

Here are a few points to think about:ammonia-graphic

  • If you breathe uncomfortably while in a pig room, or the room has visible vapour, barn workers health is at risk and the pigs are struggling too.  More often there can also be conditions where you can’t tell if ammonia (NH3) levels are elevated but if exposed to too much ammonia for an extended period of time, respiratory problems can occur.

    • From an paper from Dr. C. Dewey, B. Cox and J. Leyenaar.  Increased incidence of chronic cough, wheezing, chest tightness, irritation of the eyes………. can be experience in areas with ammonia (NH3) concentrations as low as 7 ppm.  Ammonia is expected to stay in the upper respiratory tract.  However, ammonia can adhere to dust particles and then will be carried to the smaller airways, causing more serious problems.

    • Citing Harry Huffman’s comments at the 2009 London Swine Conference.  Ammonia gas is released from the pig’s manure and should be kept at less than 20 parts per million.  Additionally, the relative humidity in the barn should be less than 70 percent.

From this information the question comes to mind:  how do we measure ammonia and humidity levels so we can manage our barn’s ventilation system to provide clean air without using too much heat?

  • Ammonia testammonia-test-strip

    • Paper test strips and Detector Tubes are available on-line or we can source them for you.

      • Directions for use are on the back of the ammonia strips package.

        • 1. Tear off a 2-inch piece of ammonia strip.

        • 2. Wet 1 inch of the strip with clean/distilled water.

        • 3. Wave the strip near animal level for 20 to 30 seconds.

        • 4. Wait 15 seconds and compare the strip color with the color chart on package.

      • Another low cost ammonia test with accuracy within 20% is called Colorimetric Tube or Detector Tube.colorimetric-tube

        • Use the provided air pump to draw air through the glass tube.

        • The chemical inside the tube will change colour

        •  Like a thermometer, you read ppm of ammonia on scale printed on tube.

        • There is also a passive detector tube that stays in place for up to 24 hours and reads an average ammonia level.

  • Humidity:  a basic humidity tester can be found at most hardware stores.  Place it in the room close to pig level during the test period.

You and your staff will quickly acclimatize to the smells of ammonia so it’s important to not just depend on the simple nose test as your air quality method.

When setting your minimum ventilation for your pigs rooms, remember the health benefits of cleaner air are more important then a few dollars in heating costs.

 

 

 

Reducing Feed Wastage

Reducing Feed Wastage

If pigs prices are up or down, if corn / soybean prices are up or down, it’s always a good idea to look at your feed delivery process to remove any wastage.

One or two small reductions in your feed wastage can result in significant dollars in your pocket.

Any of us would bend-over to pick up a $5 bill, imagine finding that $5 bill every day simply by bending over to adjust a few self feeders.

A quality New Year’s resolution would be to print this list and implement a few of them during the upcoming cold months and notice how your feed bill stretches a little further.

Check list on whole farm feed wastage areas:

  • Spillage at bin during filling.  Make sure your blow pipe is secure and without holes.  Do what you have to do to keep fines to a minimum.  Spilled feed attracts rodents.

  • Spillage and moisture in storage and unloading systems.  A little silicon goes a long way to stop moisture getting in.  If it’s beyond repair, contact us for a stainless steel flex and solid auger options that will serve you for many years.

  • Self Feeder:

    • Use a well designed self feeder that is easily adjusted and allows for proper water/feed mixing.  Dwyer Mfg can source a feeder to fit your needs.self-feeder

    • Insure there are enough feeding spaces for the pigs to eat with limited competition.

    • Even distribution of feed along the feeder.

    • Position of feeder in the pen so

      • The feeder is closer to the sleeping area, not the dunging area.  Manure in the feeder will always reduce intake and increase wastage.

      • it can be easily inspected from the passageway.

    • Locate the drinker so it can be reached but not played with and flood out the feeder pan.

    • A covered feeder is best to minimize dust in the room, reduce moisture and rodents from spoiling the feed. Include a see through area so feed can still be inspected.  Dwyer Mfg is a good source of PVC board.

    • Keep the feeder well maintained so it can be adjusted and no holes or cracks leak feed out.

    • Have feed available when the pigs enter the barn.  A detail that helps reduce lag in consumption that happens when pigs are moved.

    • Clean out your feeders thoroughly between batches.  Design your system so the feeder can be flipped upside down to really clean it out.

    • Don’t over-fill the feeders, especially when pigs first enter the barn.  Pigs will waste stale feed to find fresher.

  • Grind feed ingredients properly.  An average of 700 microns has been documented to be best.  Dwyer can do a particle test for you and provide you with a quality stainless hammer  mill.

  • Using multi-phase rations will give your pigs the correct nutrition as their needs change.  Every breed and farm can be unique, so conduct some tests to see what works best at your place. Dwyer Mfg can source or build you an affordable pig and feed weighing system.

  • Use some creep feed during the piglet’s last stage in the farrowing room.  It will ready their gut for solid food in the nursery barn. Conduct creep-feederyour own trials to find out how to fine-tune this to your system.  Dwyer Mfg has plastic and stainless creep feeders or piglet rescue decks.

  • Carefully feed a farrowing sow to meet her needs during lactation and during the first week back in the breeding barn.  Uneaten feed is a direct waste that turns moldy and attracts flies.

  • Having a “hospital” or recovery pen is a great idea but make sure the feeder is designed properly for the sick pigs that will be using it.  Keep the feed fresh and accessible. Dwyer can custom build a Stainless trough feeder for any size pig.

  • Keep rodents and birds out of the barn as best you can.  Screen naturally ventilated barns and put an anti-rodent program in place. It’s best to make it someone’s regular job or it’ll never get done. Put poison in short pieces of 2 or 3 inch pipe along the walls where rodents travel.  OMAFRA’s fact sheet on rodents CLICK HERE

  • Non-pregnant sows: It is essential that all sows 6 weeks post-mating are actually pregnant. A sow which is discovered not to be pregnant in week 16 of ‘gestation’ has just consumed 175 kg (2.5x7x10) of feed since mating. On many farms, this can be as many as 7% of sows. On a 250-sow unit, this is accounts for 3 tonnes of sow feed a year.

  • Cull sows:  Once the decision to cull a sow is made, ensure that she is culled as soon as possible. Cull sows are eating 2.5 kg a day.

  • Feeding finishing pigs prior to slaughter:  To feed a pig immediately prior to slaughter, wastes 2.5 kg per pig sold. Limit transport shrinkage by providing lots of water leading up to shipping.

  • Overweight finishing pigs:  Finishing pigs must be weighed and sold into the slaughterhouse matrix. Outside the box, the pig becomes extremely expensive.  Not only do they not earn the extra feed they have consumed, but they are going to result in a penalty at the slaughterhouse, reducing their return.  Dwyer Mfg can supply weighing systems that mark and sort pigs that meet the weight settings.

  • Review culling of runt pigs: Pigs which are born small and/or are weaned as a runt, should have their survivability carefully reviewed. Small, weak born piglets have poor FCR rate and increased mortality rate.  The feed cost of these animals needs careful review.

  • Air temperature and comfort:  Ensure that you keep the pigs within their thermo-comfort zone. If the pigs are housed too cold, feed will be consumed to help keep the pig warm.

The chart below shows clearly how feed wastage adds up in a hurry.

Joy of the Season

Joy of the Season

With the kids all out on their own, the “ba-humbug” part of me comes out much more easily.  It’s hard to go to that place with kids around the house brimming with excitement about the tree going up, wrapping presents and getting a bunch of play time with no school.  For parents it great watching the kids get along more then usual.  They plan activities together out in the snow or get out a favorite game to play together.  The older ones are more inclined to help the younger ones do things like get mom and dad’s present ready or get the toboggans ready for an afternoon of adventure out on a hill.

It seems the switch that turns the tree’s lights on also turns on the spirit of the season for me and probably lots of others.

Below is a nice video aimed at kids, but good for everyone, to learn how different cultures around the world celebrate this special season.  What struck me from this video is how there are many different traditions around the world but there is a common thread that connects us all, this is a time we all work to be nicer to our fellow man.

 

We all have family traditions around the Christmas season.  With Dutch roots in my family, we give out chocolate letters and make deep fried oliebollen and appleflappen.

Last year we set up a deep fryer in the garage, cooked up some dutch pastry and had various beverages on hand for our friends and family that came and went all afternoon.  At the end of the day your stomach might not be enjoying the 3 or 5 too many deep fried treats you had but you have a smile on your face because of the memories created.

You probably have your own too.  It might be watching a special movie from your childhood, or family hockey game, whatever it is, don’t let the “ba-humbug” feeling take root, get out of the Laze-boy chair and make some memories of your own.

Below is an interesting video of various traditions around the world.  It would be interesting to spend the next 20 Christmases visiting these countries and experience these traditions first hand.  Grab a tea or coffee and have a look.

From all of us here at Dwyer Mfg,

we wish you all the best of this special season of Good Will to All Man.

It seems the switch that turns the tree’s lights on also turns on the spirit of the season for me and probably lots of others.

Below is a nice video aimed at kids, but good for everyone, to learn how different cultures around the world celebrate this special season.  What struck me from this video is how there are many different traditions around the world but there is a common thread that connects us all, this is a time we all work to be nicer to our fellow man.

 

We all have family traditions around the Christmas season.  With Dutch roots in my family, we give out chocolate letters and make deep fried oliebollen and appleflappen.

Last year we set up a deep fryer in the garage, cooked up some dutch pastry and had various beverages on hand for our friends and family that came and went all afternoon.  At the end of the day your stomach might not be enjoying the 3 or 5 too many deep fried treats you had but you have a smile on your face because of the memories created.

You probably have your own too.  It might be watching a special movie from your childhood, or family hockey game, whatever it is, don’t let the “ba-humbug” feeling take root, get out of the Laze-boy chair and make some memories of your own.

Below is an interesting video of various traditions around the world.  It would be interesting to spend the next 20 Christmases visiting these countries and experience these traditions first hand.  Grab a tea or coffee and have a look.

From all of us here at Dwyer Mfg,

we wish you all the best of this special season of Good Will to All Man.
