Next Tuesday is Valentines Day.  It’s a fact we can’t change, but who wants to spend 3 times more for flowers?  Not me.

If you’re a little handy, you can make something yourself that will mean even more then flowers and candy.

(But not too much beats a romantic dinner that she doesn’t have to cook.  just sayin)

After a little search on the internet, here are a few projects you can get done before next Tuesday.

You can even get the kids involved for a family activity.

Heart Light Bulb

mateiloveyoubulbrials:

1. red thin gauge wire  or pipe cleaner (available at craft stores)
2. light bulb (any standard incandescent bulb with a regular size base will do..no fluorescent or halogen bulbs)
3. pliers
4. screwdriver
5. safety goggles
6. scrap piece of wood or wood cube (craft stores usually sell wood for crafts and would have a small square or chunky piece that would work)
7. 2 pins
8. paper and pen (or type written message)
9. wire cutters
10. hammer and nail (optional- if you are using soft balsa or craft wood these are not necessary)
11. hot glue gun

instructions:

1. prepare a surface on a work table for hollowing out the bulb. make sure the area is large because little chunks might jump off the base when you crack the glass.

2. follow these instructions on how to hollow out the light bulb from teamdroid.com. these are easy to follow instructions that also give good tips on safety and procedure.

3. when you have your bulb ready, clean the outside carefully and put it to the side somewhere where it is protected from breaking.

4. cut a ten inch piece of wire to make a heart “filament”. fold the wire in half to create a sharp crease, then unfold. about an inch from the crease, take both loose wire ends and loop both wires around to create the heart halves. then pull both wires back down, overlapping the center of the crease and extending beyond the heart shape. you may want to tweak the heart halves a little to get heart shape that you like. your heart should be about 1/2″ wide so it will fit through the base of the bulb pretty easily.

5. if you want two or more heart filaments in your bulb, repeat step 4 one or more times.

6. take your filaments to your bulb and hold them up to see how long the stems need to be to have the heart filaments positioned in roughly the center of the bulb. use your pliers to cut the extra wire off the ends. also test that they fit int o your bulb without having to smush them or distort the shapes. if that is the case, make them smaller.

7. if your wood is soft, you should be able to poke the wire filaments down into the top of the wood and they will stay in position. if you are using a firmer wood, use a hammer and nail to create a small guide hole. then remove the nail and push the wire down into the hole. you may want to secure these with glue as well.

8. now fit your glass bulb over the filaments and glue the bulb down to the wood at the base.

9. use the pins to attach your love note or message to the front of the piece of wood.

YOU’RE DONE!!

Valentine Mapsvalentine maps

This project will only work if you actually remember where you met, got engaged and where married to your significant other.  Let’s assume you do.

Your first job is to source a frame from department store or 2nd hand shop of some kind with 3 compartments already in it.

Next get maps that show the places you met, engaged and married him/her.

After a little cut and paste you should end up with something like what is shown in this picture.

Extra points for drawing a heart, ring and wedding bands on each map.

This works best if each of these places are different.  Mine would all be of Goderich, ON.  Nice but a little boring.

 

 

Heart Eating Dino

 

valentine dino

 

He/She will never see this one coming.  If the one you love really really likes dinosaurs or star wars or fish or what ever, simply paint it and glue some felt, paper or wooden hearts to it in an amusing way.

The dollar store or Walmart toy section should be a good place to find something fun to paint.

Spray paint it Gold or Silver or his/her favourite colour.

The finishing touch that shows how much you care is gluing on the hearts.

To get full instructions CLICK HERE.

 

 

 

Heart Magnets

If you can get Crayola air drying clay or small wooden hearts this is an easy one to do.

To get full instructions CLICK HERE

Paint red, and glue small magnets or magnet cloth to the hearts and your good to go.

 

 

 

 

 

 

 

 

 

 

 

Valentine Coasters

For full instructions CLICK HERE. valentine coasters

Cutting the slices of wood is the hardest part of this job.

Once that’s done, sand each end so they don’t wobble.

Paint hearts and initials as shown or whatever else shows how much you care.

After a couple coats of clear coat paint to seal it all, your ready to go.

Note:  you don’t have to use tree branch slices, coasters can be made from almost anything.

  • Any metal works if you glue on silicon feet.  Shiny aluminum or Stainless looks great if you have some left over pieces from another job.

  • Used tire inner tube from your tractor is a fun material.  Cut it into 4″ circles with any good scissors and paint hearts on with the same paint used on patio furniture.

  • Pallet wood is great if you find some with an interesting grain.

 

Have Fun Creating

(but don’t do too good a job, as the bar will be too high for next year)

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).

For the complete thesis CLICK HERE

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.

The decentralized system is build to fit Big D’s CL wall air inlets but can also be retrofitted for existing wall inlets. Air capacity is 1500 m3/hour

prrs apt1500 b prrs apt1500

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

Jan 4, 2017

By Gilbert VandenHeuvel

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.

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

  5. Ventilation pipe with fan and cover flap

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.

The decentralized system is build to fit Big D’s CL wall air inlets but can also be retrofitted for existing wall inlets. Air capacity is 1500 m3/hour

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.
