Swine Confinement SystemOBJECTIVES

• The following OBJECTIVES will be covered in this
  presentation
• 1. Type of Swine Confinement System
• 2. Manure Storage
• 3. Odor Control
• 4. Nutrient Application
• 5. Disposal of Carcasses

3
Type of Confinement System

• Grow/Finish Operation
• 1900 hogs per building
• Average Weight 150 lbs. per hog
• TWO enclosed hog confinement systems
• Slat Floors
• Slurry storage tank under slats
• Storage tanks hold 365 days of manure

4
Type of Confinement SystemNUMBERS

• 1900 hogs x
• 150 lb average weight x
• 2 buildings / 1000 lb/unit
• 570 units

5
Manure Storage System

• Storage Capacity 365 Days
• Volume of Manure 1,556,214 gallons per year
• Slurry mixture pumped into honey wagons

6
Odor ControlHousing

• Vegetative buffer along the west and north of
  building site
• Adequate ventilation
• Located at bottom of hill

7
Odor ControlStorage

• Containment deep pit
• Crust forms on stored manure, thus blocking odor

8
Odor ControlLand Application

• Soil Injection to reduce odor
• Apply on non-windy days
• Watch wind direction
• Morning applications

Nutrient and ApplicationManure Numbers

• TS 1,166,838.6 lbs/year
• VS 1556.2 x 562.35 875,129 lbs/year
• FS 1556.2 x 187.45 291,709 lbs/year

Nutrients and ApplicationNutrient Numbers

• N 1556.2 lbs/1000 gal. x 52.48 lb/1000 gal.
• 81, 667 lbs Nitrogen
• P 1556.2 lbs/1000 gal. x 22.50 lb/1000 gal.
• 35,014.5 lbs Phosphorus
• K 1556.2 lbs/1000 gal. x 18.33 lbs/1000 gal.
• 28,525 lbs Potassium

12
Nutrients and ApplicationLand Application - P

• Applying for crop removal rate of 175 bushel of
  corn
• Needed for phosphorus application 27 lbs/A
• Application rate 1200 gal./A
• Acres covered 1297 acres

13
Disposal of CarcassesComposting

• Death loss 4
• 364 head per year
• 2.4 turns in confinement building per year
• 14 compost bins needed
• Sawdust used as carbon source
• Skid loader used for turning compost piles

14
Conclusion

• Manure storage system is appropriate for
• Number of hogs
• Odor control
• Nutrient needs
• Land application needs
