Comparison of Urination Frequency of Grower-Finisher Pigs to Ammonia Emission
Ammonia emissions have negative consequences on the environment, animals and workers in the swine industry. Urine breakdown produces ammonia in puddles and slurry. If urine puddle numbers are known, ammonia emission predictions can be made using a computer model. Puddles...
Hydrogen Sulphide Concentration While Pulling Pit Plugs and Power-Washing Rooms
Liquid manure produces hydrogen sulphide which is a life-threatening gas. It is believed that hydrogen sulphide levels may be high when pulling pit plugs and power-washing rooms. Six pig farms were monitored in regard to this hypothesis. All barns that...
Draeger microPac Performance for Hydrogen Sulphide Monitoring in Commercial Swine Operations
Hydrogen sulphide is a major hazard in swine facilities and must be monitored carefully. The monitors are subjected to a harsh environment including high humidity, dust and gas levels. The Draeger microPac unit was evaluated for detecting hydrogen sulphide in...
Feasibility Study for Concrete Swine Buildings and Manure Storage Facilities in Western Canada
Most swine facilities in the Prairies are constructed with wood framing and earthen manure storage facilities. Concrete walls may increase the buildings longevity and rodent control. Concrete manure tanks and walls decrease the production facilities annual costs and increases longevity....
Manure Management in Zero Till Systems
A broader range of nutrients can be provided with manure fertilizer compared to inorganic products. In order to properly use manure, nutrient and soil analyses are needed. Nutrient take time to be released after application of manure; in cattle, they...
Airborne Dust, Endotoxin and DNA Downwind from Swine Barns: An Update
Dust exhausted from swine barns may have endotoxins and microbial DNA present which is an environmental and health concern. Endotoxin is a pulmonary irritant which can cause phlegm, cough, wheezing, fever and in some cases chronic airway inflammation. Microbial DNA...
Clogging and Flow Reduction in Soil Materials by Ponded Hog Manure
An economically viable option for storing manure is using earthen manure storage. Proper construction and soil materials are crucial to avoid contamination. Soil pores can be clogged by liquid hog manure, though this clogging is a surface effect and can...
Influence of Hog Manure Application on Water Quality and Soil Productivity
Impacts of organic fertilizers on the environment are not known on ecosystems that are semi-arid to sub-humid. Hog manure is a source of nutrients as a fertilizer and more research should be done to understand its impact. The presence and...
Earthen Manure Storage Monitoring: PSC Elstow Research Farm Inc.
As the Saskatchewan hog industry grows, so does the publics environmental awareness. This has led to earthen manure storages having higher standards to uphold to. These improvements have not decreased public concern, so solute migration through the liners of different...
Oil Sprinkling and Dietary Manipulation to Reduce Odour Control and Gas Emissions from Grower-Finisher Buildings – Laboratory Scale Experiment
Hog barns emit a continuous emission of odours by the ventilation system which have a negative impact on the surrounding area. Canola oil sprinkling and specific pig diets may be able to decrease the gas and odour emissions from swine...
Two-Airspace Buildings Design for Reducing Odour and Gas Emissions from Grower-Finisher Barns
Nearby residents often find odour and gas emissions from swine operations to be a nuisance. Most barns have outside manure storage which increases the odour sources; the outside manure storage and the barn. To reduce the emissions from the area,...
Optimizing of a Sprinkling System using Undiluted Canola Oil for Dust Control in Pig Buildings
High dust levels in pig barns are a health hazard for farm workers. Different methods have been tested with oil spraying or sprinkling being the most effective method so far. Unfortunately, this used to require very intensive labour to manually...
