Large swine production facilities have become controversial additions to the agricultural landscape as their numbers and sizes have increased. In addition to being larger enterprises, these units...
Optimization of a sprinkling system using undiluted canola oil for dust control in pig buildings
January 1, 1999
An oil sprinkling system has been designed to control dust levels in pig buildings using undiluted crude canola oil and was previously tested over a two-week period. The system was tested again over...
Estimating the availability of nutrients from processed swine lagoon solids through incubation studies
January 1, 1999By Miressa Duffera
Potential environmental hazards from the excess accumulation of swine (Sus scrofa domesticus) manure in eastern North Carolina and new state guidelines on treatment alternatives have necessitated the...
Phosphorus Fractionation in Manure from Swine Fed Traditional and Low-Phytate Corn Diets
January 1, 1999By Brian Wienhold
Traditional corn (Zea mays L.) (TC), the primary grain used in swine (Sus scrofa) diets, stores a majority of its P as phytate, which is largely unavailable for digestion by nonruminant animals....
Reduction of odour and gas emissions from swine buildings using canola oil sprinkling and alternate diets
January 1, 1999
This three year project evaluates the impact of four different canola oil application rates combined with specific diet formulations on odour and gas emissions from grower-finisher swine buildings....
Impacts of swine manure pits on groundwater quality
January 1, 1999By I. G. Krapac
