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 buildings. Three diets were observed,...
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, the manure could be kept...
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 spray the oil and its...
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 manure from swine directly from...
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 and Westbridge (H4-5O2). The additives...
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. Room temperature and relative humidity...
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 was the temperature-humidity control system...
Performance and Carcass Quality of Growing-Finishing Pigs Submitted to Reduced Nocturnal Temperature
In the summer, higher temperature in the barn reduces feed intake and therefore reduces pig growth rate. To modify eating behaviour and stimulate the average daily feed intake, a reduced temperature setpoint during the summer was proposed. A reduced nocturnal temperature strategy was implemented with...
Engineering Controls Reduce Hydrogen Sulphide Exposure in Swine Barns
Three engineering control measures were developed and tested for effectiveness in protecting swine barn workers from exposure to hydrogen sulfide (H2S) gas during manure handling events. A remote manure pit plug pulling system allowed the worker to pull the manure pit plug from outside the room. A water sprinkling apparatus...

Pigs Consume more Water When Stressed
Two novel technologies consisting of an individual water consumption system (IWCS) and infrared thermography system (ITHS) were installed in a finishing room. The individual water consumption system (installed in each pen) was composed of a nipple drinker attached to a water flow meter, and an...
