Dynamic Simulation Model of Nitrogen Fluxes in Pig Housing and Outdoor Storage Facilities
Posted in: Environment by admin on January 1, 2005 | 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.

Data Mining to Improve the Bottom Line
Posted in: Environment by admin on | No Comments
In recent years, the North American swine industry has evolved rather dramatically from being largely comprised of family-farming type businesses to being dominated by large integrated meat protein producing firms operating in several industries. Because of the changes associated with this evolution, the leaders of the swine industry have been transaction focused for too long. This includes buying new assets and making new deals. As leaders of the North American swine industry are forced to manage their businesses rather than just grow them in an effort to become competitive, their focus will increasingly be on making their businesses profitable. As has occurred with other non-agricultural industries, understanding opportunities to increase profitability through cost and revenue management will be integral to the success of pork businesses. Data mining will be the key to that understanding. You do not have to be good in mathematics to mine data, you just need to know arithmetic and be willing to study numbers.
