Improvements in pork production efficiency have always been important to maintaining a viable and competitive Canadian pork sector. Because increasing production costs often outstrip increases in farm gate commodity values, improved production efficiencies assume an important role in maintaining farm profitability. In the past, combining environmental sustainability with positive economic spin-offs for the farm has been difficult. In many cases, pork producers have implemented conservation practices, with little return on investment. An overall industry willingness to provide this societal service has resulted in the generation of a forward thinking and environmentally responsible industry. The emergence of a new area of environmental sustainability, greenhouse gas management, has the potential to offer some quantity of cost recovery for environmental sustainability and potentially increase farm income.

Dynamic Simulation Model of Nitrogen Fluxes in Pig Housing and Outdoor Storage Facilities
Posted in: Environment by admin on | No Comments
Many factors in pig production, including genetics, feeding efficiency, feed composition, feed distribution method, environmental control, and waste management, affect the nitrogen content of pig slurry. However, estimating the global impact of these factors on the nitrogen (N) content of daily fresh manure and stored slurry is not easy. Mathematical modelling of certain N fluxes in pig production systems have shown good potential for predicting the impact of some of the aforementioned characteristics on either pig excretion or ammonia volatilisation in buildings and outdoor storage facilities. However, none considered both excretion and ammonia volatilisation over the entire production site. To do this, equations from the literature were used to construct a dynamic simulation model of N fluxes in both batch and continuous production systems. The resulting model allows for prediction of daily concentrations and quantities of N in buildings and storage facilities. Total N concentration in outside slurry tanks can be accurately predicted within an error range of 64% forthe growing–finishing site and 93% for the reproduction site.
