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...
PAMI Builds Tanker Truck for Research and Demonstration
A truck-based system with vacuum/pressure tank was developed to apply swine manure to research and demonstration plots throughout Saskatchewan. It can travel long distances, use a high or low disturbance injection to apply swine manure and be able to pump...
Nitrogen Dynamics in Manured Saskatchewan Soils
Manure is a nitrogen source for crop growth. To predict its behaviour in the soil, the amounts and forms of nitrogen must be known. The behaviour of the manure nitrogen as a plant nutrient source is influenced by the soil...
Effectiveness of Three Manure Pit Additives
Evaluation of three manure pit additives on their effectiveness in reducing manure strength and solids, odour threshold and gas concentrations above the manure surface, and maintaining micronutrient and nutrient content was completed. The additives investigated were Pit Boss, American BioCatalysts...
Development and Evaluation of a Temperature-Humidity Controller for Livestock Buildings
A TDK relative humidity sensor’s life expectancy and accuracy could be improved by applying a specific protection treatment, allowing humidity control strategies. Evaluation of the modified TDK relative humidity sensor and the temperature and humidity control strategy (THC) was completed....
Humidity Control Strategies for Winter Conditions
Automatically adjusting ventilation according to room humidity could optimize energy requirements while improving the buildings room conditions. Under Prairie winter conditions, a conventional temperature control system and a temperature-humidity control system were evaluated through a computer model. The optimum strategy...
