The animal environment and energy costs all are impacted by ventilation. When converting to a group-housed sow barn, retaining the existing ventilation system leads to over-ventilation in winter as they are designed for a higher animal density. This can chill...

Sows in groups may have a lower critical temperature that is lower than sows housed in individual stalls as they can use thermoregulatory behaviour. If productivity does not changes, reducing energy costs for ventilation and heating may be an option....

Land application of livestock wastewater is creating challenges for producers due to costs and environmental impacts. Finding alternatives is of great interest in order to have  safe disposal with reduced costs. Wastewater contains nitrogenous and organic compounds that can be...

Transporting breeding stock across Canada is a daily occurrence with farms each having biosecurity procedures to reduce potential disease outbreaks. Infecting breeding stock during transport is a risk, especially through pig dense areas. Measures are needed to protect breeding stock...

Wide variations in building design, barn equipment, construction, management and other operational systems contribute to added costs and inefficiencies in hog barns. These variabilities make it difficult to develop improvement measures and they cannot be applied from barn to barn...

Different methods of swine manure use are of interest Crop response to swine manure biodigestate produced by biogas production compared to the conventional liquid swine manure and urea fertilizer was looked at. Applying long and short-term fresh and processed liquid...

A production cost that can be further reduced is energy cost. This can be done by reducing overall energy consumption or using energy more efficiently. Space heating is an area of interest for energy reduction. The performance of a heat...
