Single and Double Welded Cups

Hog Slat highlighted an additional watering option for finishing pigs at the 2016 World Pork Expo. This all stainless steel welded cup is available in single and double models and designed with several features producers will appreciate.

Note formed gap in back plate to prevent manure buildup.

The back plate of welded cup is formed with a gap off the gate to allow any manure accumulating there to be easily washed out. This prevents premature rusting of gate rods common with cups mounted back to back without this gap.

Two-piece water pipe.

The unique design of the two-piece water pipe allows for easy replacement if it should ever become damaged or bent. The separate ½”x 48” long pipe installs into a female coupler on top of the cup. A specially designed bracket is included to mount the pipe to the top angle on a gate.

Mounting cups back to back is simple with four bolts or single cups can be mounted with a U-bolt around a horizontal gate bar.

The size of individual sow farms continues to increase; just a few years ago 2,400 head units were considered large, but new sow farms under construction this year range between 5,000 to 14,000 head in size.

Building cross-section comparison

Designing the central production facility into two or three larger buildings has many advantages including smaller land requirements, less underground utilities to bring to the site, shorter roadways to build and maintain, fewer walkways between buildings and less linear footage of exterior building walls.

Because of increased pig capacities and the desire to minimize the number of buildings, it was necessary to increase the buildings widths up to 190 feet.  Instead of the 4/12-pitch roof used on standard farm buildings, these jumbo-wide facilities utilize a two-piece rafter with a 1/12-pitch roof line resting on a center support wall in the middle.  Almost 6 feet high at the heel with a center height of 13 feet, the rafters are designed more like a large floor joist. The outside appearance resembles a steel frame building more than conventional wood framed structures.

Breeding/ Gestation

Galvanized gestation stalls

Totally slatted flooring is a common feature of newly constructed B&G buildings. While past layouts consisted of a solid laying area with slat sections in the rear of the pen or stall only, new construction plans incorporate slats over the entire floor with stainless feeding troughs fastened in place. This arrangement allows long-term flexibility to reconfigure the pen layout in the future if needed.

Group housing with stanchions is the predominant type of housing under construction this year. Largely through trial and error, the industry seems to have settled into pen configurations containing eight to twelve sows. This pen size permits closer grouping by size and condition and promotes easier visual inspection.

Whether the production system chooses gestation stalls, stanchions, or ESF, most equipment is specified with hot-dipped galvanized equipment instead of painted finish. The extended equipment life provided by the galvanized finish makes this an economical business decision.

One advantage reported with stanchion systems is longer equipment life resulting from moving the water away from the front of the stanchions. Locating a cup or swinging water pipe with nipples in the center of the pen reduces the deterioration of feed pipes and stall fronts by minimizing water contact with these areas.

Farrowing

Large pen farrowing crates with SowMAX feeders

Jumbo style layouts permit designing a double farrowing building with an extra wide 8-foot center alleyway to aid in animal and people movement between rooms.

Almost every new construction project increases the length and width of the farrowing crates and creep area from the standard 5′ x 7′ footprint up to 6’ wide by 8′ long, with some systems choosing 8’6″ long crates. Longer framed sows and reduced piglet crushing rates from using wider pens have driven this trend. Again, the equipment will have a galvanized finish with a combination of cast iron, TriDek, or plastic slats for flooring choices.

Most production systems will incorporate some provision for ad-lib sow feeding. Besides reducing farm labor, ad-lib sow feeding is the most efficient method for feeding individual sows to reach full milk production potential. The type of systems can range from electronic transponder metering devices to sow activated hopper type feed dispensers.

Swinging rafters on new farrowing house

Projects of this size require builders with an expanded skill set. A builder must be able to provide professional project management, understanding of regulatory issues, and increased insurance coverage. It is also critical for any construction firm undertaking projects of this size to have sufficient financial backing and the ability to manage large cash flows.

Not every labor saving idea for swine confinement lasted much past the initial development phase. From the 1960 Yearbook of Agriculture, we present the HOG-O-MATIC!

Hog-O-Matic

This automatic hog finishing facility – dubbed “Hog-O-Matic” – is equipped to feed the pigs and clean the floor under fully automatic control. Cleaning is done (below) with two jets of water under 70 pounds of pressure. The revolving boom circles the 21.5- foot exercise area every 2.5 minutes. A 4-inch center drain carries the wastes away.

High-Pressure Water Jets clean pen floor

A good idea in theory for the time, but it is likely this system would not work well with sub-zero temperatures during a typical Midwestern winter.  Here’s a more typical finishing floor from the early confinement years.

Reverse mono-slope finishing floors with rear access alley.

Hogs are housed in clean, airy, efficient buildings. The picture above shows one of the many new types of confinement housing during this time period. Raising hogs in confined quarters is a growing practice. The farmer designed this pen arrangement (below) with the plan of finishing two-thousand hogs per year. 

Labor-saving equipment included automatic watering and feeders filled with an overhead auger.

From these early designs, the industry continued to develop into the improved feeding and ventilation systems we have today. GrowerSELECT feed systems and AirStorm ventilation fans offer today’s producers great equipment backed by the best warranty in the business.

Rodney and Brett Bowden with new Airstorm 54″ fan

To the best of my knowledge, when we built them in 1989, these were the first tunnel/natural ventilated houses constructed in the state,” explained Rodney Bowden at his family farm near Clinton, NC.  “We’ve always had good results in the buildings, but the recent upgrades have improved our performance.”

Rodney added two GrowerSELECT 54″ AirStorm fans per house to increase airspeed and reduce the ambient temperature.  The durable AirStorm 54″ fans feature a fiberglass housing, plastic shutters, and a stainless steel prop.

GrowerSELECT Classic Flood feed pans

The next step in the upgrade was to replace the original feed pans with GrowerSELECT Classic Flood feeders. Rodney said, “Installing the new pans helps minimize wasted feed when the birds are young and has improved my feed conversion during grow out.”

These investments have paid off with an increased bird performance and helped Rodney settle in first place among his group several times since the upgrade.

Nameplate from GrowerSELECT fan motor

Today’s livestock and poultry operations rely on electric motors for a variety of feeding and ventilation functions. Used in buildings that can be both dusty and humid, with fluctuations in voltage and varying workloads we subject our motors to a very hostile work environment.

When selecting replacement motors, it is important to select motors that are both efficient and designed with a “safety factor” that will allow them to last under harsh conditions.

While you may be familiar with the term Service Factor or S.F., there are a couple of important designations found on a motor nameplate that may need more clarification.

Service Factor is defined as a motor’s ability to operate under a short-term load.   The higher a motor’s S.F. rating, the more durable the motor.  Motors with high S.F. are expected to last longer. To illustrate, a 1-1/2 Hp motor with a 1.5 S.F. can provide 2.25 Hp for short-term use.   However, it is not a good practice to continuously operate a motor above the rated workload. In other words, the same 1-1/2 Hp motor with  1.5 SF would not be selected to power a 60″ fan originally shipped with a 2 Hp motor.

Full Load Amps or F.L.A. represents the amount of current the motor is designed to draw at the rated horsepower. In the example nameplate, this means that when the motor is running under a full load at 230 volts, we can expect it to draw 5.4 amps. Motors with a lower F.L.A. for the amount of horsepower are considered more efficient to operate.

Service Factor Amps or S.F.A. represents the amount of current the motor will draw when running at the full Service Factor. In the example nameplate, the S.F.A. is eight amps at 230 volts.

Continually exceeding the S.F.A. shown on the nameplate can shorten motor life. Motors with a higher S.F.for the same horsepower have an increased “safety factor” and are expected to last longer under harsh conditions.

The most efficient, rugged motors are designed with a higher S.F., lower F.L.A., and higher S.F.A ratings. By comparing the information on a motor nameplate, we can select the best replacement motors for feeding and ventilation equipment.

Hog Slat designed the GrowerSELECT line of motors to help simplify a producer’s decision on selecting replacement motors. GrowerSELECT motors feature a high Service Factor (as high as 1.5) and higher  S.F.A. rating to increase motor life.  Each model number is a direct cross to the most popular brands of feed systems and fans used on producers’ farms. No matter what your existing brand of equipment we have a GrowerSELECT motor designed to replace it and save money while doing so. Shop GrowerSELECT motors.

GrowerSELECT Proxy Control on display  at the 2016 World Pork Expo

One of the products Hog Slat introduced at the 2016 World Pork Expo is designed to give pork producers an improved method for controlling feed line motors.

The GrowerSELECT Proximity Drop Tube Control features a flat proxy sensor that can detect feed levels through the plastic housing. The flat proxy mounts to the side of the feed tube and doesn’t require drilling a hole for installation. The compact design takes up less room on the control compared to rod type proxy sensors.

GrowerSELECT HS752

Flat Sensor

Like it happens with many advancements in electronics this improved sensor costs less than existing technology.  A quick online search shows replacement rod type proxy switches costing between $117 and $150.  The complete HS752 unit costs $125 and can replace the feed level control on any existing feed system.

How can we make the claim of selling the strongest, heaviest feed bins on the market at the best possible price to swine and poultry growers?

Traditional multilevel supply chain vs. Hog Slat’s Direct Distribution

Simple. Our direct distribution system eliminates the additional markup that dealers have to add to the bin’s price. Instead, that money goes back into building a stronger bin manufactured from heavier steel. These longer lasting bins are built with 5-10% more steel, by weight, than competitive brands.

Compare the features.

Most manufacturers only use 50,000 psi structural steel for the bin sheets and legs to reduce costs.  Hog Slat bins are constructed entirely of GRADE 55 structural steel.  The bin sheets, legs, roof sheets, bottom cone sheets…the entire bin.

Heavy, dent resistant bottom cone sheets.

The bottom cone sheets of a bin are subjected to extra abuse from hammers and mallets used to dislodge bridging feed.  That’s why we used thicker steel to resist dings and dents.

Heavy 10 gauge collar

We build the bin collar out of heavier 10 gauge steel to eliminate having to add additional reinforcing collars. The collar is stamped to reduce variations in dimensions compared to rolled or spun collars.

Every Hog Slat / Georgia Poultry bin is manufactured in-house for complete control of raw material purchasing and manufacturing operations.  Our facility includes state-of-art rolling, stamping and finishing machinery to ensure precise fit and finish.

Heavier bins, Stronger bins. Bins designed to last longer.

It starts with the selection of steel. Most feed bins are built from a mixture of steel grades. The sidewall sheets and legs are manufactured from Grade 50 structural steel (50,000 psi) while the other components are produced using a commercial grade type B steel (33,000 psi) The entire Hog Slat bin is manufactured using only Grade 55 Structural Steel with a superior strength of 55,000 psi.

We use stronger steel in the smallest part of our bin than the competition does in their most critical components.

We didn’t stop there.

We also use heavier gauges of steel in every part of the bins; including thicker bottom cone sheets, that resist dents from hammers, to bin collars over four gauges thicker than competitive brands.

Our state-of-the-art, in-house manufacturing allows us to produce heavier, stronger products with precision for ease of assembly and proper fit along with features designed to protect both the operator and the stored feed.

Our improved WeatherEdge™ design directs water away from the hopper, and rounded trapezoid ladder rungs provide for secure footing, exceeding OSHA safety standards. Hog Slat feed bins also feature a spring loaded lid that folds flat, below the fill ring, to protect it from damage during filling.

We are so confident of the quality of the bins that we offer the industry’s best warranty, an extended FIVE-YEAR warranty.

In addition to the great design and durable construction, one of the most important features of our feed bins is the local assembly, delivery, and service provided by our extensive store network. Our local stores selling directly to the end-user allows us to help eliminate extra costs and add value that makes choosing your next feed bins a simple choice.

Longer-lasting bins, a better warranty and local service.

Management expert Peter Drucker is often quoted as saying that “you can’t manage what you can’t measure.” We believe this is particularly true when it comes to developing, improving and testing ventilation fans.

Hog Slat’s Wind Tunnel

Hog Slat’s AirStorm and Windstorm ventilation fans are designed and tested using an Airflow Performance Test Chamber, or as it more commonly known, a Wind Tunnel. Measuring 10′ x 10′ x 28′ long, the Wind Tunnel was constructed according to AMCA standard 210 and installed at the Clinton, NC facility in May 2015.

Fans to be tested are fixed in place on one end of the Wind Tunnel.

Air Forcing fan powered by a 20 HP motor

A 48″ axial vane fan, powered by a 20 hp motor, located on the opposite end of the tunnel, forces air into the chamber.

Nozzle Wall

After passing through a series of mesh straighteners, the air is then forced through a nozzle wall consisting of metal cones that can be opened and closed to change available square inches of space.

Pressure transmitters feed data to the automated recording system.

Two devices, called Differential Pressure Transmitters, measure and record the static pressure differential on each side of the nozzle wall.  To maintain precise accuracy, the transmitters are calibrated monthly and are also returned to the manufacturer for a factory re-calibration once per year.

One of the key features of Hog Slat’s test chamber is the automated recording system that records data without any manual input from an operator. The Wind Tunnel is ramped up from zero to maximum static pressure while up to two data points per second are recorded in real time. This automated recording system is a custom program developed by a team from Hog Slat’s engineering group. This allows Wind Tunnel technician, Matt Parker, to supply the engineering group with a complete fan performance graph instead of limiting the information to only a few selected data points.

Technician Matt Parker views display screen readouts.

Lead engineer for ventilation products, Tyler Marion explains; “Having a Wind Tunnel in-house allows us to quickly break down a fan by critical components and test multiple variables quickly. We are able to test different motor/fan combinations, shutter designs, and cone styles to constantly improve the fans Hog Slat delivers to our customers.”

QC testing fan blades

Hog Slat’s Wind Tunnel is not only used for fan testing and development, it also serves as a Quality Control check on products received from suppliers. The photo above shows a galvanized prop mounted in standard fan ring. In this case, the initial run of product from the vendor is being checked against the approved sample. This testing continues for each production run to ensure the same performance levels from lot to lot. QC checks are also run for completed fans pulled from inventory and checked against published standards for airflow, CFM/watt and motor amperage.

Matt tests a Windstorm 36″ Box Fan using the Thrust Tester.

A new addition to our fan testing equipment is the device called a Thrust Tester. The Thrust Tester measures the amount of thrust (lbf or pounds of force) a stir or circulation fan develops.  It also measures the thrust efficiency ratio of a fan by dividing the lbf by kWs used. Although the Thrust Test is a stand-alone unit, it is tied into the Wind Tunnel transmitters to record the data. Matt also records centerline velocity at distances five times the prop diameter.

Here’s another selection from the 1960 edition of The Yearbook of Agriculture on the latest trends in farrowing.

Welfare-friendly farrowing pens

Caption in yearbook:
In this minimum-stress pen, the shape of the guardrail encourages the sow to lie with the teats toward the pigs. The pigs stay where it’s warm – under the heat lamp and behind the guard.

How about this for Ad Lib feeding? An overhead auger delivers feed to the farrowing pens. No carts or scoops are needed.

Labor saving feeding from the past.

And finally, double-decker farrowing crates! I saw one of these set up in Red Oak, Iowa years ago.

From the yearbook:
Hogs in double-deck, all steel, cage-type farrowing stalls. The pigs are transferred after weaning. Manure is removed by mechanical drags.
