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...

Filtration and mixing methods using zinc oxide nanoparticles were effective in controlling odour, ammonia and hydrogen sulphide emissions from swine facilities. This is important to the health and safety of the workers and the environment as well. The feasibility of...

The rate of water use in swine production impacts the overall production cost and the environment. It is usually used for cleaning, animal drinking, cooling and domestic use. The quantity of water use in the different production stages and units...

Different management and engineering measures can control the levels of air contaminants like dust and ammonia in swine facilities. This helps lower the safety risk of workers in the barn. Control measures were assessed on their effectiveness on decreasing respirable...

Profitability of swine production will be improved with any measure that reduces production cost. Using energy efficiently will help reduce the cost of energy. This can be done in the area of space heating. Energy consumption, in barn environment and...

A long-term concern to humans, animals and the environment are the environmental emissions produced by hog production operations. Previous work investigated nanoparticles and their ability to control hydrogen sulphide, ammonia and odour emissions from swine manure. Zinc oxide nanoparticles had...
